These processes include the evolution of 17 the Session Initiation Protocol (SIP) and related protocols, as well 18 as the operation of the DISPATCH and SIPCORE working groups. This 19 document updates RFC 5727 to allow flexibility for the area and 20 working group structure, while preserving the SIP change processes. 21 It also generalizes the DISPATCH working group processes so that they 22 can be easily adopted by other working groups. 24 Status of This Memo 26 This Internet-Draft is submitted in full conformance with the 27 provisions of BCP 78 and BCP 79. 29 Internet-Drafts are working documents of the Internet Engineering 30 Task Force (IETF).

Introduction 71 [RFC5727] describes processes for evolving and maintaining the 72 Session Initiation Protocol (SIP) [RFC3261] and related technologies 73 in the former Real-time Application and Infrastructure (RAI) area. 74 These processes are collectively known as the "SIP Change Process". 75 While areas do not normally have "charters" per se, RFC 5727 has 76 effectively served as a charter for RAI. The language in RFC 5727 is 77 tightly bound to the RAI area and to the the DISPATCH and SIPCORE 78 working groups. 80 At the time of this writing, the RAI area recently merged with the 81 Applications (APP) area to form a new Applications and Real-Time 82 (ART) area. This document updates RFC 5727 to remove its dependency 83 on RAI and its working group structure. 85 RFC 5727 specifies that the DISPATCH working group assesses potential 86 new work for the area, and determines where such work should occur. 87 DISPATCH does not itself take on such new work. The SIPCORE working 88 group is responsible for maintenance of SIP. Other RAI working 89 groups develop extensions to SIP that do not change the core 90 protocol, new applications of SIP, and other technologies for 91 interactive communication among humans. This document further 92 generalizes the processes of the DISPATCH working group so that they 93 can be applied to other areas, or to clusters of technologies within 94 an area. 96 While the reorganization is expected to involve merging RAI with the 97 Applications (APP) area and renaming the resulting area, the updates 98 in this document do not depend on that. Rather, the authors seek to 99 future-proof the SIP Change Process against future reorganizations. 101 This document does not change any other aspect of RFC 5727. While 102 areas and working groups may change over time, the rules and 103 procedures for changing SIP and other RAI protocols remain the same, 104 until such time that they are updated by future documents. 106 2. Dispatch-Style Working Groups 108 The DISPATCH working group has proven successful at managing new work 109 for the RAI area. Areas may choose to adopt DISPATCH-like 110 procedures, either for an entire area, or for technology-clusters in 111 an area or across areas. A "Dispatch-Style" working group operates 112 according to procedures similar to those used for DISPATCH. 114 The "Dispatch Style" includes the following essential elements: 116 o The working group evaluates proposals for new work for an area, or 117 for a well-defined technology cluster. It acts as a filter for 118 the area or cluster to determine whether a proposal is a 119 reasonable use of or addition to associated technologies. This 120 determination may depend upon established criteria (for example, 121 the SIP Change Process), the experience and expertise of the 122 participants, or a combination of the two. 124 o The dispatch-style working group determines an appropriate venue 125 for the work. The venue could be an existing working group. If 126 no appropriate group exist, it may develop a charter for a BoF, a 127 new working group, or an exploratory group [RFC5111]. The working 128 group may also determine that a proposal should not be acted upon 129 at the time. 131 o The dispatch-style working group does not complete the proposed 132 work. It may, however, adopt milestones needed to properly 133 dispatch the work. For example, it may produce charter text for a 134 BoF or a new working group, an initial problem statement, or 135 documentation about why certain work was not pursued. 137 Nothing in this list prevents existing working groups from directly 138 adopting new work that reasonably fits their charters. For 139 borderline cases, the decision whether new work should start in a 140 dispatch-style group, or in an existing group is a judgement call 141 among the responsible Area Directors and chairs. Likewise, in cases 142 where an area has multiple dispatch-style groups for different 143 purposes or technology clusters, the decision about which group will 144 handle a particular proposal is a judgement call. 146 The charter of a dispatch-style group should make that fact clear, 147 either by referencing this document, or by directly describing 148 similar procedures. 150 3. Decoupling the SIP-Change Process from the RAI Area 152 This document clarifies that the SIP Change Process is not bound to 153 any particular area or working group structure. All references to 154 the RAI area in RFC 5727 should be interpreted as "the cluster of SIP 155 and closely related application and infrastructure technologies, as 156 well as other technologies designed primarily for interactive 157 communication among humans." 159 While the DISPATCH and SIPCORE working groups are expected to 160 continue in their current capacities, nothing in the SIP Change 161 Process prevents their responsibilities from being assigned to other 162 working groups in the future. 164 All other aspects of the SIP-Change process are to continue as 165 described in RFC 5727. 167 4. IANA Considerations 169 This document makes no requests to IANA. 171 5. Security Considerations 173 This document discusses the roles and responsibilities of areas and 174 working groups. It does not create new security considerations in 175 the conventional sense. 177 However, organizational structures come with their own security 178 considerations. A dispatch-stye working group has the potential to 179 concentrate the control of work for an area or cluster in the hands 180 of a much smaller set of people than those in the whole area or 181 cluster. This could have the effect of a "Denial of Service Attack" 182 against the area or cluster. Likewise, such a concentration could 183 reduce the quality of decisions about new work. Care must be taken 184 to avoid this risk. The best mitigation is active participation in 185 the group by as many people in the area or cluster as possible. 187 6.
