- Description of Working Group:
- SIP is another candidate for IPv7. The purpose of the Working Group
- is to finalize the SIP family of protocol, and to foster the early
- development and experimentation of this protocol.
-
- There are two major characteristics of the SIP proposal: it is very
- much a continuation of IP, and it aims at maximum simplicity. A
- short hand definition of SIP could be ``64 bits IP with useless
- overhead removed''.
-
- Following the IP model, SIP uses globally-unique addresses,
- hierarchically structured for efficient routing. SIP addresses are
- 64 bits long, which we believe adequate to scale the Internet up
- to, say, thousands of internet-addressable devices in every office,
- every residence, and every vehicle in the world.
-
- The quest of simplicity in SIP has been described as parallel to the
- RISC philosophy. The minimal SIP header contains only those fields
- which are necessary to achieve our goal: routing packets efficently
- in a very large internet. As a result of this design philosophy, the
- SIP header is much simpler than the IP header. Simplicity
- facilitates high-performance implementation and increases the
- likelihood of correct implementation.
-
- Contrary to several other IPv7 candidates, the SIP effort is
- focused mostly on the description of the final state, not on the
- description of the transition. This is due to a coordination with
- the IPAE working group, which has already engaged an intensive study
- of transition problems, with SIP in mind as a final state.
-
- Goals and Milestones:
-
- Done Post the complete SIP specification as an Internet-Draft. This
- specification shall include the header format, the address format,
- ICMP and IGMP, the fragmentation protocol, the source route protocol,
- and the the requirements SIP imposes on higher layer protocols and
- lower later protocols, e.g., ARP.
-
- Done Post an Internet-Draft specifing the SIP addressing and routing
- architecture. Include discussion of multicast and mobile host support
- as well as a discussion of how policy routing can be supported.
- Detail the changes required to OSPF, BGP, and RIP.
-
- Jan 93 Post as an Internet-Draft a specification for the SIP MIB. Detail the
- operation of SNMP over SIP.
-
- Jan 93 Make available a public domain implementation of SIP for the UNIX-BSD
- socket environment.
-
- Jan 93 Make available a public domain version of modified TCP and UDP for
- the UNIX-BSD socket environment.
-
- Mar 93 Post as an Internet-Draft a report on the initial implementation and
- experience with SIP.
-
- Jun 93 Incorporate security into SIP.
-
- Done Post an Internet Draft specifying changes to RIP needed for SIP.
