Please refer to the current edition of the "Internet + Official Protocol Standards" (STD 1) for the standardization state + and status of this protocol. Distribution of this memo is unlimited. + +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/ + Session Description Protocol (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. + + + + + + + + + + + + + + + + + + + +Garcia-Martin Standards Track [Page 1] + +RFC 5112 Presence Dictionary for SIGCOMP January 2008 + + +Table of Contents + + 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 an 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], or + the Location Object in PIDF [16]. + + Typically, presence documents can contain large amounts 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., 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 networks 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. + + + + + +Garcia-Martin Standards Track [Page 2] + +RFC 5112 Presence Dictionary for SIGCOMP January 2008 + + + 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 previously 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 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-specific 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. + + + + + +Garcia-Martin Standards Track [Page 3] + +RFC 5112 Presence Dictionary for SIGCOMP January 2008 + + + 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 evolves. It is + defined once, and it 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 + 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 farther down at the + bottom, we have decided to allocate a priority to each string in + the dictionary. Priorities range from 1 to 5. A low value in the + priority column (e.g., 1) indicates that we believe there is 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. + + + + +Garcia-Martin Standards Track [Page 4] + +RFC 5112 Presence Dictionary for SIGCOMP January 2008 + + + 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 include 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. + + o When a string appears as an XML element in an XML document, it is + typically surrounded 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 made the decision to + omit the '<' and '>' signs because then we can easily reuse the + same string for start-tags (e.g., <foo>), start-tags that contain + attributes (e.g., <foo attr="myattr">), empty-element tags (e.g., + <foo/>), and end-tags (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. + + + + +Garcia-Martin Standards Track [Page 5] + +RFC 5112 Presence Dictionary for SIGCOMP January 2008 + + + The binary SigComp dictionary is composed 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, Table 2, fully characterizes the + state item. + + Note that the string subset of the dictionary can be accessed using: + + STATE-ACCESS (%ps, 6, 0, 0x0955, %sa, 0), + + and the table subset can be accessed using: + + STATE-ACCESS (%ps, 6, 0x0955, 0x043E, %sa, 0), + + where %ps points to Universal Decompressor Virtual Machine (UDVM) + memory containing + + 0xd942297d0bb3 + + and %sa is the desired destination address in UDVM memory with UDVM + byte copying rules applied. + + + + + + + + + + + +Garcia-Martin Standards Track [Page 6] + +RFC 5112 Presence Dictionary for SIGCOMP January 2008 + + + 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 |
