Ivip - a potential new routing and addressing architecture for the Internet

msg01518.html 2007-06-15 ViP: Anycast ITRs in the DFZ & mobile tunnels

General introduction, starting with contrast with my understanding of LISP.

msg01542.html 2007-06-16 Ivip (was ViP ...)

More introduction.

msg01547.html 2007-06-17

Ivip-basic and Ivip-mobile, with the TTR (Translating Tunnel Router) and a two-way tunnel to the mobile host.

Responding to questions about how Ivip compares with Mobile-IPv4/6 and NEMO.

msg01550.html 2007-06-18

The need to allow for "pull" queries from ITRs which do not attempt to maintain a full up-to-date copy of the database.

msg01555.html 2007-06-18

Further discussion of comparison with Mobile-IPv4/6 and NEMO - the different types of tunnel which are used in Ivip-basic and Ivip-mobile.
Example of how more and more prefixes mapped to the Ivip system may reduce the number of BGP advertisements needed, as gaps are filled and multiple subnets join into a single longer subnet.

msg01561.html 2007-06-19

Where the ITRs would be located and who would run them and pay for them.
Musing about how a single Ivip system might be introduced, and whether RIRs should allow address space to be used for alternative Ivip systems.

msg01563.html 2007-06-22

Similarities and differences with various forms of Mobile IP, including Proxy Mobile IPv6.
Speculation that LISP or Ivip would be needed if and when IPv6 becomes widely adopted - and either would have a profound effect on Mobile-IPv6 (MIPv6) and perhaps diminish the importance of SHIM6.

Detecting multihoming failures.

msg01628.html 2007-07-04

ITR/ETR functions in hosts, NATs & servers - not in routers?
Making an ITR with one or more ordinary PC Linux/BSD servers, rather than a router.

Since BGP's limitations are driving this whole LISP/Ivip thing, please also see also the discussion of BGP's path hunting, the MRAI timer etc. in the RRG and IDR mailing lists, beginning around 2007-06-20. I have a little guide to this discussion at: ../../sram-ip-forwarding/##BGP_hunting_MRAI_disc .
