Abstract The Session Initiation Protocol (SIP) [4] is a text-based protocol for initiating and managing communication sessions. The protocol is extended by the SIP-events framework [5] to provide, e.g., subscriptions and notifications to presence information that are carried in presence documents [8]. SIP can be compressed by using Signaling Compression (SigComp) [2], which is enhanced by using the SIP/SDP dictionary [7] to achieve better compression rates. However, Garcia-Martin Expires September 3, 2007 [Page 1] Internet-Draft Presence dictionary for Sigcomp March 2007 the SIP/SDP dictionary [7] is not able to increase the compression factor of (typically lengthy) presence documents. This memo defines the presence-specific static dictionary that SigComp may use in order to achieve higher efficiency. The dictionary is compression algorithm independent. Table of Contents 1.

Introduction The Session Initiation Protocol (SIP) [4] is extended by the SIP- events framework [5] to provide, e.g., subscriptions and notifications to presence information. The presence information is typically carried in Extended Markup Language XML documents that are compliant with a given XML schema. For example, the Presence Information Data Format (PIDF) [8] defines the format for the basic 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], or Timed Presence Extensions to PIDF [13]. 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 scare (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 SigComp [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, SDP and SigComp. 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. Garcia-Martin Expires September 3, 2007 [Page 3] Internet-Draft Presence dictionary for Sigcomp March 2007 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 announce the availability of one or both dictionaries during the Sigcomp initialization phase. 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 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 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. Garcia-Martin Expires September 3, 2007 [Page 4] Internet-Draft Presence dictionary for Sigcomp March 2007 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 consideration that require a bit more explanation. For example, when a string appears as an XML element in an XML document, it is typically prepended by the '<' and '>' signs, such as in ''. 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., ), opening elements that contain with attributes (e.g., ), empty elements (e.g., ), and closing elements (e.g., ). Whenever there is an enumerated string, the string does not contain Garcia-Martin Expires September 3, 2007 [Page 5] Internet-Draft Presence dictionary for Sigcomp March 2007 quotes, following the same pattern like any other input string. 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 [1], a SigComp state is characterized by a certain set of information. For the presence-specific static dictionary, the information in the following Figure 3 fully characterizes the state item. Note that the string subset of the dictionary can be accessed using: STATE-ACCESS (%ps, 6, 0, 0x0980, %sa, 0), and the table subset can be accessed using: Garcia-Martin Expires September 3, 2007 [Page 6] Internet-Draft Presence dictionary for Sigcomp March 2007 STATE-ACCESS (%ps, 6, 0x0980, 0x04B9, %sa, 0), where %ps points to UDVM memory containing 0x46f8c65183ca 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 0x07E2 0x019E 0x0980 0x0045 1..2 0x0712 0x026E 0x0980 0x0075 1..3 0x0442 0x053E 0x0980 0x0159 1..4 0x02C8 0x06B8 0x0980 0x01C2 1..5 0x0000 0x0980 0x0980 0x04B9 Figure 1: Priority Table The state item consists of the following elements: Name: Value: ===================== ======================== state_identifier 0x46f8c65183ca690bfc34426e34ee3cc3ca2ab484 state_length 0x0E39 state_address 0 (not relevant for the dictionary) state_instruction 0 (not relevant for the dictionary) minimum_access_length 6 state_value Representation of the table below.
