1. Introduction
The Interface to the Routing System (I2RS) Working Group is chartered
with providing architecture and mechanisms to inject into and
retrieve information from the routing system. The I2RS Architecture
document [I-D.ietf-i2rs-architecture] abstractly documents a number
of requirements for implementing the I2RS requirements.
The I2RS Working Group has chosen to use the YANG data modeling
language [RFC6020] as the basis to implement its mechanisms.
Additionally, the I2RS Working group has chosen to use the NETCONF
[RFC6241] and its similar but lighter-weight relative RESTCONF
[I-D.ietf-netconf-restconf] as the protocols for carrying I2RS.
NETCONF and RESTCONF are suitable for handling the configuration

Internet-Draft I2RS Data Flow March 2016
portion of the I2RS protocol, but need extensions to handle the I2RS
use cases described in [I-D.ietf-i2rs-usecase-reqs-summary]. The
requirements for these functionalities include:
o ephemeral state - as defined in [I-D.ietf-i2rs-ephemeral-state]
o notifications and events - as defined in
[I-D.ietf-i2rs-pub-sub-requirements]
o traceability - as defined in [I-D.ietf-i2rs-traceability]
o protocol security - as defined in
[I-D.ietf-i2rs-protocol-security-requirements]
o Generic interfaces to Protocol Local-RIBs or Policy Data bases,
o Large data flows,
o Traffic monitoring data,
o Data flows for Action sequences, and
o data flows during network outages or attacks
This document describes the protocol requirements for these last five
types of requirements. The first section summarizes the data flow
requirements gathered from the Use Cases. These list of requirements
are being presented to the I2RS Working group to determine if the
requirement is need for the first revision of the I2RS protocol.
Future revisions may add additional data flow requirement. The
authors have indicated their suggestion with the following
abbreviation:
v1 - version 1, or
fv - future version
Section 2 details how the I2RS use case requirements for Generic
interfaces to protocol RIBS or policy data base do not add any
requirements to the I2RS protocol. Section 3 describes how the
describes
2. Summary of I2RS Data Flow Requirements
Additional requirements from Generic Interface:None
The additional Data flow requirements are:
Hares & Dass Expires September 22, 2016 [Page 3]
Internet-Draft I2RS Data Flow March 2016
DF-REQ-01: Support writing to the ephemeral copy of the Local RIB
with three different types of checks: minimal data reception
checks (TLVs of data oacket valid), all non-referential checks
(e.g. do not do leafref, MUST, instance identifiers), and do
referential checks via three different rpcs. [v1]
DF-REQ-02: The support of large data transfers in a data format
agnostic format. The NETCONF protocol now supports XML and JSON.
I2RS protocol should also support other data formats (MTL [fv],
raw ascii stream [fv])
DF-REQ-03: Support of I2RS Agent and I2RS Client negotiating
specific transport and transport options out the options that are
available (v1),
DF-REQ-04: Support for the ability to send traffic monitoring
information using IPFIX protocol and IPFIX templates (fv),
(DF-REQ-05): Support of traffic statistics for filter-based
policies (BGP-FS, I2RS FB-RIB, policy routing), IPPM, SFLOW, and
others in yang data model format. (authors mixed - v1 or fv)
DF-REQ-06: I2RS should be able to support an action which
allocates internal resources for the I2RS agent (memory,
processing time, interrupts) and outbound data flow bandwidth. It
is expected that an action would be included in a data model in an
"rpc"-like format in yang. (v1)
DF-REQ-07: The I2RS should be able to support an action that
interacts with routing OAM functions. [Editor: Operator-applied
priorities and manual control must support limiting I2RS actions
with OAM.] (v1 or v2)
DF-REQ-08: The I2RS Agent must be able signals that it will be
using different protocol with different constraints (security,
priority of data, or transport) or different constraints on the
existing protocol (smaller message sizes, different priorities on
data carried, or different security levels). (v2) [Editor's Note:
Should this be for network outages or for just security attacks?]
DF-REQ-09: Yang MUST have a way to indicate in a data model has
actions which allow: different transports, different resource
constraints, or different security. (v1)
DF-REQ-10: Yang MUST have a way to indicate a data model has
different levels of checking where: lowest level is message form
only, medium level checks message format plus data syntax, and
highest level uses the message format, data syntax and referential
Hares & Dass Expires September 22, 2016 [Page 4]
Internet-Draft I2RS Data Flow March 2016
check netconf configuration does. The default level for I2RS is
message format plus data syntax. (v1)
3. Generic Interfaces to Routing Functions
The I2RS use case requirement suggests that a generic interface be
created to protocol local RIBs and a generic interface be available
to configure policies.
3.1. I2RS-Generic Interface to Local-RIB
The I2RS requirements ([I-D.ietf-i2rs-usecase-reqs-summary]) require
that a generic interface be defined to the local-RIB in protocols.
This type of data flow does not require a new type of data flow, but
the definition of a new data model that creates a generic local RIB
and has operations to funnel this generic Local-RIB to a specific
protocol.
The Protocol Independent Use case (PI-REQ-11) Local RIB use case
suggest the I2RS protocol has three levels of checks: minimal data
reception checks (TLVs of data align), all non-referential checks
(e.g. do not do leafref, MUST, instance identifiers), and do
referential checks. This feature could be supported through
different rpc calls to the LOCAL RIB.
3.2. I2RS-Generic interfaces to Policies
The I2RS requirements suggest that I2RS have a generic interface to
routing policies for protocols, routing distribution, or routing
protocols. This generic interface is currently being implemented as
common definitions for data models. At this time, This generic
interface does not need additional protocol requirements.
3.3. I2RS Data Flow Requirements
[DF-REQ-01] Support writing to the ephemeral copy of the Local RIB
with three different types of checks: minimal data reception checks
(TLVs of data oacket valid), all non-referential checks (e.g. do not
do leafref, MUST, instance identifiers), and do referential checks
via three different rpcs.
4. Large Data Flow Requirements
This section decribes the data flow requirements for large data
flows, traffic flows measurements, CDNI traffic flows, OAM and Action
rqeuests, data flows during outages or network attacks (DDoS
(Distributed Denial of Service) or other network attacks), and non-
Hares & Dass Expires September 22, 2016 [Page 5]
Internet-Draft I2RS Data Flow March 2016
secure data flows. These data flows are data flows which are not
configuration based data flows.
4.1. Large Data Flow Use Case Requirements
The I2RS use case for Large Data Collection systems
[I-D.ietf-i2rs-usecase-reqs-summary] requires the I2RS protocol and
data models:
o be able to be done at a high frequency and resolution with minimal
impact to devices memory or CPU (L-Data-REQ-01) ,
o use a data model which allows definition of the form as part of
the data model (L-Data-REQ-02) ,
o support a publication/subscription mechanism with push/pull
mechanism (L-Data-REQ-03),
o (supports capability negotiation for level of transport, security,
and error handling as a general configurations, per I2RS client-
agent protocol for all interfaces and all time instance, or per
I2RS interface client-agent protocol per specific interface or per
time instances. (L-Data-REQ-04,L-Data-REQ-06, L-Data-REQ-07, L-
Data-REQ-08, and L-Data-REQ-09),
o dynamic subscription model set-up via IPFIX (L-REQ-12c),
o support of subscriber and consumer I2RS-Agent pairs (L-REQ-12d),
o remapping of Node's databases,
o data format agnostic (L-Data-REQ-05),
o data models and I2RS protocol additions that support of query,
introspection using data-base model that support a set of
capabilities, data filters, and error handling (stale data,
repeated transport failures, and other errors.) Introspection
supports data verification, inclusion of legacy data, and merging
of data flows based on meta-data. (L-Data-REQ-11, L-Data-REQ-13),
o Support of push of data synchronously or asyncronously via
registered subscriptions (L-Data-REQ-12a).
o Pull of data in one-shot or multiple sequences (L-Data-REQ-12b),
and
o dynamic subscription model set-up via IPFIX Feed (?) (L-REQ-12c)
Hares & Dass Expires September 22, 2016 [Page 6]
Internet-Draft I2RS Data Flow March 2016
4.1.1. Data Requirements Supported in pub-sub Requirements
All use case requirements for the publication/subscription service
for the push service from large data requirements 01-04 and 6-12 is
found in [I-D.ietf-i2rs-pub-sub-requirements], and an example
protocol addition to netconf is include in
[I-D.ietf-netconf-yang-push].
The requirements for the publication/subscription service for the
pull model are not specified in the
[I-D.ietf-i2rs-pub-sub-requirements], but a majority of the pub-sub
requirements and mechanisms can be reused. In a pull, the publisher
prepares the data that is pulled by a few receivers who then
distribute it to the receivers. The pull mechanism would have a
different "pull latency" versus the push latencey, and a set of
parameters which indicate the amount of data stored if receivers did
not pull the data within a certain time.
At this time, the pull-model of the publication/subscription model is
not being requested by vendors or operators.
4.1.2. Data Flow Requirements Outside of Pub/Sub Requirements
The data flow requirements for large data flows also include support
for data flows outside of publication/subscription via any transport
(L-Dat-REQ-04) and any data format (L-Data-REQ-05). It is unclear
whether the L-DATA-REQ-12 really wants to utilize IPFIX protocol or
just IPFIX templates to handle the montoring data.
Editor note: It becomes a question for the WG as to whether these are
necessary for version 1 of the I2RS protocol, version 2 or never.
4.1.3. I2RS Data Flow Requirements
The following requirements are additional data flow requirements for
large data flows.
(DF-REQ-02): Support of any data format including: XML, JSON, (MTL
(Alias/WaveFormat,.mtl), protobufs, and ascii. NETCONF already
supports the pub/sub push model with XML and JSON. It is
important to determine what is needed.
DF-REQ-03: Support of I2RS Agent and I2RS Client negotiating
specific transport and transport options out the options that are
available,
(DF-REQ-04): support of the ability send information using IPFIX
templates over the IPFIX protocol. [Note: This requirement is
Hares & Dass Expires September 22, 2016 [Page 7]
Internet-Draft I2RS Data Flow March 2016
unclear in the use case so it is included here to determine the
working groups input. This would include I2RS protocol to have
NETCONF/RESTCONF + IPFIX.]
[I-D.ietf-netconf-yang-push] supports XML and JSON in its first
release, and provides an ability to register extra formats, but these
requirements should also support large data flows sent outside of the
publication-subscription service.
4.2. Traffic Flow Measurements
The I2RS requirements for the Protocol independent use cases requires
the support off interactions with traffic flow and other network
management Protocols (requirements PI-REQ-05, PI-REQ06) in
[I-D.ietf-i2rs-usecase-reqs-summary]).
The following IETF protocol pass traffic related information:
o BGP Flow Specification (BGP-FS) ([RFC5575]
o IPFIX - IP Flow Information ([RFC7011]) that reports on a wide
variety of routing system statistics, and
o IPPM - IP Performance mangement ([RFC2330], [RFC7312]) that
reports on one-way or two-way end-to-end network performance
statistics,
In addition the SFLOW([RFC3176]) of layer 2 devices is supported by
many routers. Other traffic flows may be measured in support of IDS/
IPS, but these will be covered in the section on security flows.
Additional traffic flow models are being defined to configure traffic
flow policy and to monitor the statistics on the use of the traffic
flow statistics:
o BGP Flow Specification (BGP-FS) yang model
[I-D.wu-idr-flowspec-yang-cfg] contains flow filter match
statistics.
o I2RS Filter-Based RIB yang model
([I-D.kini-i2rs-fb-rib-info-model],
[I-D.hares-i2rs-fb-rib-data-model])- yang model contains ephemeral
flow statistics,
o Filter-Based RIB (draft-hares-rtgwg-fb-rib-data-model) contains
both flow filter match statistics,
Hares & Dass Expires September 22, 2016 [Page 8]
Internet-Draft I2RS Data Flow March 2016
4.2.1. Protocol Requirements based on Traffic Flows
Due to the potentially large data flow these statistics should be
handle by push pub-sub model or a pull pub-sub model. Thresholds for
data models may be passed by the event portion of the push/pull pub-
sub model. The pub-sub model will allow the I2RS client-I2RS Agent
to meter the amount of data flow these statistics carry. The push
portion of the pub-sub model is supported by
[I-D.ietf-netconf-yang-push], but the pull portion of the pub-sub
model is not defined.
Alternatively I2RS can use the the IPFIX protocol ([RFC7011]) as a
component protocol. I2RS processes can support an IPFIX exporting
process sendinging dta to a node to a node on a collector process.
The IPFIX templates can be configured as ephemeral state or
configuration state. The IPFIX data flows may run over SCTP, UDP, or
TCP utilizing the congestion services at each time. The IPFIX
connections assumes that: a) congestion is an temporary anomaly, b)
dropping data during a congestion is reported, and c) for some
exporiting process it is acceptable to have drop data in a reliable
protocol. The I2RS protocol must support the establishment of an
IPFIX connection.
Traffic monitoring can occur in a network under DDoS with high levels
of congestion and loss the use of these protocols which rely on
transport-level retransmission may not be as resilient as needed for
network security functions (NSF). These are considered in section 5
on operations during network outages or congestoin.
The Flow Filtering data models with policy rules (BGP Flow
Specification, I2RS Filter-Based RIB, and n-tuple policy routing RIB)
often track how often these policies are match. These statistics can
also be pushed/pulled in a publication/subscription with yang data-
model defined format or an IPFIX exporting process format. Similarly
IPPM statistics or SFLOW data, be sent via publication/subscription
service in yang data model format or in a IPFIX Template or as XML or
JSON representation of a yang data model. These additional sources
do not change the requirements for the push publication/subscription
or expand the
Summary: The pub-sub model push or pull may have to support
additional formats (E.g. SFLOW, IPFIX) as well as yang data models.
4.2.2. I2RS Data Flow Requirements
DF-REQ-04: Support for the ability to send traffic monitoring
information using IPFIX protocol and IPFIX templates, [Editor: This
requirement is unclear in the use case so this requirement is to
Hares & Dass Expires September 22, 2016 [Page 9]
Internet-Draft I2RS Data Flow March 2016
confirm the I2RS WG desire for NETCONF/RESTCONF + IPFIX == I2RS
protocol]
(DF-REQ-05): Support of traffic statistics for filter-based policies
(BGP-FS, I2RS FB-RIB, policy routing), IPPM, SFLOW, and others in
yang data model format.
4.3. Action sequences in Data Models
This section considers the data flow requirements in sequences of
actions (e.g. calculate topology and install), and actions that
interact with TCAMs (e.g. putting filters in TCAMs).
4.3.1. Action sequences
Several of the I2RS requirements from the use cases require a
sequence of events with the following actions:
1. query data in protocol independent model (topology, RIB, Filter-
RIB), or protocol),
2. start calculation (or re-calculation) in protocol function,
3. Report results,
4. install topology or RIB calculated,
5. check results,
6. recycle.
The actions included looking for overlapping BGP routes, IGP LFA
calculation, ECMP load balancing traffic, optimizing paths via MPLS-
TE, CCNE re-optimization, and virtual topology creation.
An alternate pattern within the requirements is if the topology is
calculated off-line, and uploaded.
These action patterns may involve an interaction of the I2RS action
sequences with existing OAM functions in the routing system.
NETCONF/RESTCONF have the concepts of an "rpc" for a configuration
enabled action, but these action sequences should have the abilty to
have the following characteristics:
o the ability to request a reservation of resources for this effort
so the action sequence does not start unless there is enough
calculation or response bandwidth in a node,
Hares & Dass Expires September 22, 2016 [Page 10]
Internet-Draft I2RS Data Flow March 2016
o the abilty ability to have validation on off-line calculated data
so this critical data does not have errors
o the ability to "prioritize" notification or reports ahead of other
I2RS data streams to allow process to work.
4.3.2. TCAM use case
Note: TCAM (hardware memory)in general is used in m ost of the
routing devices for faster address lookup that enables fast routing.
The TCAM also provides the flexibility to manually specify how much
TCAM space you want to allocate to a specific feature or action (like
routing, switching, security , ACL etc.). There may be cases when a
manual allocation of memory (H/W or S/W) could restrict the I2RS
functions. To allow operators the control they need, the manual
allocation must be considered.
A few questions need to be consider:
o how do we handle Action sequences or TCAM?
o After the allocation internal resources, what shall be the timing
or proces to release those resources?
o What should happen in case there are issues getting the internal
resource allocation done? - Should we just send a event/error to
the client or should something else happen?
4.3.3. I2RS Data Flow Requirement
I2RS-DF-REQ-06: I2RS should be able to support an action which
allocates internal resources for the I2RS agent (memory, processing
time, interrupts) and outbound data flow bandwidth. It is expected
that an action would be included in a data model in an "rpc"-like
format in yang.
DF-REQ-07: The I2RS should be able to support an action that
interacts with routing OAM functions. [Editor: Operator-applied
priorities and manual control must support limiting I2RS actions with
OAM.]
4.4. Operation during network outages or attacks
The router needs dynamic management during periods of outage or
periods of security attack.
Hares & Dass Expires September 22, 2016 [Page 11]
Internet-Draft I2RS Data Flow March 2016
4.4.1. Periods of Network Outage
During periods of outage, the I2RS protocol must operate when data
bandwidth is reduced and network connectivity fluctuates. I2RS
agents must be able to adjust operation of event notifications,
logging, or data traffic during this period. Data Models and I2RS
agent configuration must allow operator-applied policy to prioritize
data during this period. The I2RS Agent should be able to signal the
I2RS Client that such a time period is occuring.
Some periods of outage are caused by security attacks (DDoS or target
incident that exploit vulnerabilities in software, network devices,
protocols.) [I-D.hares-i2nsf-mgtflow-reqs] provides a description of
the data flow needed from network security controllers to the network
security devices or firewalls in routers. Editor's Note: I2NSF is
reviewing this draft, and will give feedback on this requirement.
Network Outages may occur due to several issues including the
security reasons but network downtimes caused by security reasons may
also be quite diverse, for example a network outage due to DDoS
attack, botnets, malware attack, identity theft, or incidents that
incident that exploit vulnerabilities in software, network devices,
protocols. And if an outage has occurred due to security reasons
then other safeguard measures could overlap with the I2RS based
prioritization.
Since these outages can overlap with the network security controllers
using I2NSF protocol to contact the network service functions (NSF)
or virtual service functions (vNSF), the I2NSF working group should
be consulted to determine what I2RS versus I2NSF needs are, and what
conflicts exist. [I-D.hares-i2nsf-mgtflow-reqs] provides a
description of the data flow needed from network security controllers
to the network security devices or firewalls in routers. The I2NSF
WG is reviewing this draft.
Editor's note: Do we want a general OAM feature or a feature specific
to DDoS and security attack case?
4.4.2. I2RS Data Flow Requirements
DF-REQ-08: The I2RS Agent must be able signals that it will be using
different protocol with different constraints (security, priority of
data, or transport) or different constraints on the existing protocol
(smaller message sizes, different priorities on data carried, or
different security levels). [Editor's Note: Should this be for
network outages or for just security attacks?]
Hares & Dass Expires September 22, 2016 [Page 12]
Internet-Draft I2RS Data Flow March 2016
5. Changes to YANG
To support the above requirements, the yang modules will need to
support the following features:
o DF-REQ-09: Yang MUST have a way to indicate in a data model has
actions which allow: different transports, different resource
constraints, or different security.
o DF-REQ-10: Yang MUST have a way to indicate a data model has
different levels of checking where: lowest level is message form
only, medium level checks message format plus data syntax, and
highest level uses the message format, data syntax and referential
check netconf configuration does. The default level for I2RS is
message format plus data syntax.
