Abstract
The Session Initiation Protocol (SIP) is a text-based protocol for
initiating and managing communication sessions. The protocol is
extended by the SIP-events notification framework to provide
subscriptions and notifications of SIP events. One example of such
event notification mechanism is presence, which is expressed in XML
documents called presence documents. SIP can be compressed by using
Signaling Compression (SigComp), which is enhanced by using the SIP/

SDP dictionary to achieve better compression rates. However, the
SIP/SDP dictionary is not able to increase the compression factor of
(typically lengthy) presence documents. This memo defines the
presence-specific static dictionary that SigComp can use in order to
compress presence documents to achieve higher efficiency. The
dictionary is compression algorithm independent.

Internet-Draft Presence dictionary for Sigcomp May 2007
1. Introduction
The Session Initiation Protocol (SIP) [4] is extended by the SIP-
events framework [5] to provide subscriptions and notifications of
SIP events. One example of such event notification mechanism is
presence. The presence information is typically carried in
Extensible Markup Language (XML) [22] documents that are compliant
with a given XML schema [23]. The Presence Information Data Format
(PIDF) [8] defines the format for the basic presence document that
supplies presence information. Typically, PIDF is used in
combination with other extensions to provide a richer user
experience, among others: the Presence Data Model [10], Rich Presence
Extensions to PIDF (RPID) [11], Contact Information in PIDF (CIPID)
[12], the SIP Event Notification Extension for Resource Lists [19]
and the SIP User Agent Capability Extensions to PIDF [20].
Typically, presence documents can contain large bulks of data. The
size of this data is dependent on the number of presentities that a
watcher is subscribed to and the amount of information supplied by
the presentity. This can impose a problem in environments where
resources are scarce (e.g., such as low bandwidth links with high
latency) and the presence service is offered at low or no cost. This
is the case, e.g., of some wireless network and devices. It is
reasonable to try to minimize the impact of bringing the presence
service to wireless networks under these circumstances.
Work has been done to mitigate the impact of transferring large
amounts of presence documents between endpoints. For example, the
Partial PIDF [15] reduces the amount of data transferred between the
endpoints.
On the other hand, the signaling compression mechanisms specified in
the SigComp framework (RFC 3320) [2] provide a multiple compression/
decompression algorithm framework to compress and decompress text-
based protocols such as SIP. When compression is used in SIP, the
compression achieves its maximum rate once a few message exchanges
have taken place. This is due to the fact that the first message the
compressor sends to the decompressor is only partially compressed, as
there is not a previous stored state to compress against. As the
goal is to compress as much as possible, it seems sensible to
investigate a mechanism to boost the compression rate from the first
message.
RFC 3485 [7] defines a the static dictionary for SIP [4] and SDP [9].
The dictionary is to be used in conjunction with SIP [4], SDP [9] and
SigComp [2]. The static SIP/SDP dictionary constitutes a SigComp
state that can be referenced in the first SIP message that the
compressor sends out. The dictionary boosts the compression of SIP

and SDP, but unfortunately, does not have any effect in XML-based
presence documents.
It sounds reasonable to define a presence-specific static dictionary
that can be used in conjunction with SIP and Sigcomp. This
dictionary can coexist with the static SIP/SDP dictionary defined in
RFC 3485 [7]. Sigcomp endpoints will initially announce the
availability of one or both dictionaries until the other end
acknowledges that it has received the announcement.
Our initial simulations when developing this dictionary reveal that,
once the current mitigation mechanisms are applied (e.g., Sigcomp,
partial notification, partial publication), a further compression
factor of 10% can be achieved when Sigcomp uses the presence-specific
static dictionary.
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in BCP 14, RFC 2119 [1]
and indicate requirement levels for compliant implementations.
3. Design considerations
The presence static dictionary is a collection of well-known strings
that appear in most of the presence documents used by SIP. The
dictionary is not a comprehensive list of reserved words, but it
includes many of the strings that appear in presence documents.
The presence static dictionary is unique and MAY be available in
SigComp implementations for SIP that support the presence service.
The dictionary is not intended to evolve as presence evolve. It is
defined once, and stays as is forever. This solves the problems of
updating, upgrading and finding out the dictionary that is supported
at the remote end when several versions of the same dictionary
coexist.
Appendix A contains the collection of strings that were contributed
to the presence static dictionary. The appendix also includes
references to the documents that define those strings.
While this appendix is of an informative nature, Section 4 gives the
normative binary form of the presence-specific static dictionary.
This is the dictionary that is included in the SigComp
implementation. This dictionary has been formed from the collection
Garcia-Martin Expires November 29, 2007 [Page 4]
Internet-Draft Presence dictionary for Sigcomp May 2007
of individual dictionaries given in Appendix A.
The input set is a collection of UTF-8 [6] encoded character strings.
The appendix provides a table where each row represents an entry.
Each entry contains the string that actually occurs in the
dictionary, its priority (see below), its offset from the first octet
and its length (both in hexadecimal), and one or more references that
elucidate why this string is expected to occur in presence documents.
Note: Length in this document always refers to octets.
The columns in the table are described as follows:
String: represents the UTF-8 string that is inserted into the
dictionary. Note that the quotes (") are not part of the string
itself.
Pr: indicates the priority of this string within the dictionary.
Some compression algorithms, such as DEFLATE [3], offer an
increased efficiency when the most commonly used strings are
located at the bottom of the dictionary. To facilitate generating
a dictionary that has the most frequently occurring strings
further down at the bottom, we have decided to allocate a priority
to each string in the dictionary. Priorities range from 1 until
5. A low value in the priority column (e.g., 1) indicates that we
believe in a high probability of finding the string in a presence
document. A high value in the priority column (e.g., 5) indicates
lower probability of finding the string in a presence document.
This is typically the case for less frequent extensions or
optional infrequent XML elements or attributes.
Off: indicates the hexadecimal offset of the entry with respect to
the first octet in the dictionary. Note that several strings in
the collections can share space in the dictionary if they exhibit
suitable common substrings.
Len: the length of the string in octets in hexadecimal.
References: contains one or more references to the specification and
the section within the specification where the string is defined.
Note that the strings stored in the dictionary are case sensitive.
(Again, the strings do not comprise the quotes ("), they are just
shown here to increase the readability).
There are a few design considerations that require a bit more
explanation:
o Due to the fact that most compression algorithms have a break-even
point around three or four characters, we have selected those
static strings of characters that consist of four or more
characters.
Garcia-Martin Expires November 29, 2007 [Page 5]
Internet-Draft Presence dictionary for Sigcomp May 2007
o When a string appears as an XML element in an XML document, it is
typically prepended by the '<' and '>' signs, such as in '<foo>'.
It would have been natural to include the '<' and '>' signs of the
element in each input string. However, we took the decision of
omitting the '<' and '>' signs because then we can easily reuse
the same string for opening elements (e.g., <foo>), opening
elements that contain with attributes (e.g., <foo attr="myattr">),
empty elements (e.g., <foo/>), and closing elements (e.g.,
</foo>).
o Whenever there is an enumerated string, the string does not
contain quotes, following the same pattern as any other input
string.
o In a few cases, we have decided to split a string that appears a
few times into a few substrings. This is the case of Uniform
Resource Names (URNs) in the IETF address space, because this
allows the dictionary to reuse the same substring in various URN
strings.
4. Binary representation of the presence-specific static dictionary
This section contains the binary form of the presence-specific static
dictionary that is loaded into SigComp as a state.
The binary SigComp dictionary is comprised of two parts, the
concatenation of which serves as the state value of the state item: A
string subset, which contains all strings in the contributing
collections as a substring (roughly ordered such that strings with
low priority numbers occur at the end), and a table subset, which
contains pairs of length and offset values for all the strings in the
contributing collections. In each of these pairs, the length is
stored as a one-byte value, and the offset is stored as a two-byte
value that has had 1024 added to the offset (this allows direct
referencing from the stored value if the dictionary state has been
loaded at address 1024).
The intention is that all compression algorithms will be able to use
the (or part of the) string subset, and some compression methods,
notably those that are related to the LZ78 family, will also use the
table in order to form an initial set of tokens for that compression
method. The text below therefore gives examples for referencing both
the table subset and the string subset of the dictionary state item.
As defined in section 3.3.3 in the Signaling Compression
specification [2], a SigComp state is characterized by a certain set
of information. For the presence-specific static dictionary, the
information in the following Table 2 fully characterizes the state
item.
Garcia-Martin Expires November 29, 2007 [Page 6]
Internet-Draft Presence dictionary for Sigcomp May 2007
Note that the string subset of the dictionary can be accessed using:
STATE-ACCESS (%ps, 6, 0, 0x0951, %sa, 0),
and the table subset can be accessed using:
STATE-ACCESS (%ps, 6, 0x0951, 0x0453, %sa, 0),
where %ps points to UDVM memory containing
0x554a2da68469
and %sa is the desired destination address in UDVM memory with UDVM
byte copying rules applied).
If only a subset of the dictionary up to a specific priority is
desired (e.g., to save UDVM space), the values for the third and
forth operand in these STATE-ACCESS instructions can be changed to:
+---------------+------------+------------+------------+------------+
| Priorities | String | String | Table | Table |
| desired | offset | length | offset | length |
+---------------+------------+------------+------------+------------+
| 1 only | 0x07A7 | 0x01AA | 0x0951 | 0x0039 |
| 1..2 | 0x06DD | 0x0274 | 0x0951 | 0x0066 |
| 1..3 | 0x04DE | 0x0473 | 0x0951 | 0x0144 |
| 1..4 | 0x028E | 0x06C3 | 0x0951 | 0x01B0 |
| 1..5 | 0x0000 | 0x0951 | 0x0951 | 0x0453 |
+---------------+------------+------------+------------+------------+
Table 1: Priority Table
The state item consists of the following elements:
+----------------------+--------------------------------------------+
