RE: [RRG] Publicly available LISP and shim6 implementations

Luigi,
 
SEAL is right now implemented as a Linux kernel protocol module, and
used to support tunnel-mode and transport-mode applications. It sounds
like what you need is an application-mode instantiation of SEAL, where
the layering would be something like:
 
  Inner-IP/LISP-SEAL/UDP/Outer-IP
 
In that case, to do it at the application layer we would simply need to
pull the 'seal.c' code up into your application and implement some kind
of packet filter that could capture IPv4 first-fragments ICMPv4 "Fragment
Needed" messages at the application layer. That shouldn't be too hard, I
don't think?
 
I'll desist now since this is vectoring off into discussion that should go
to the other lists. But, I just wanted to have this application-layer
implementation option for SEAL out on the table since it isn't well
documented in the current spec.

Hi Fred,

in the new openlisp report we cited seal (section 6.8.2)

I do not know yet the details of your implementation, but if it runs in the user space, thanks to OpenLISP's mapping sockets, to set MTU towards specific RLOCs is pretty easy.

Cheers

Luigi

Oliver et al,

Integrating LISP with SEAL is a possible next step of interest.
If you would like to try putting your implementation together
with SEAL, let me know:


(IMHO, in the future our LISP should be SEALed.)

Fred

Subject: [RRG] Publicly available LISP and shim6 implementations

Hello,

To allow researchers to experiment with some of the mechanisms 
that are 
being extensively discussed on the RRG mailing lists, we are happy to 
announce the public release of two implementations :

- OpenLISP is the first publicly available implementation of 
the Locator 
Identifier Separation Protocol (LISP) that has been extensively 
discussed within the RRG. OpenLISP runs on the FreeBSD kernel and has 
been written by Luigi Iannone.

- LinShim6 is the first implementation of the shim6 IPv6 host-based 
multihoming solution developped within the IETF shim6 working group. 
LinShim6 runs on the Linux kernel and has been written by 
Sebastien Barré.

You can find additional details (implementation reports, source code, 
papers, ...) about these two implementations from our webpage :



Best regards,


Olivier Bonaventure

PS: Discussion about LISP/shim6 should be sent on the 
lisp/shim6 mailing 
lists and not on the RRG mailing list
