Re: [tsvwg] WGLC Announcement for draft-ietf-tsvwg-sctp-udp-encaps-14 to confirm changes - 5th April 2013

[Thomas Dreibholz <[e-mail]>]

Dear Gorry,

I would like to express my support for the draft draft-ietf-tsvwg-sctp-udp-
encaps-14. It is a very useful extension to make use of SCTP in certain setups 
where SCTP is not possible otherwise, e.g. when blocked by firewalls or not 
supported by operating system kernels.

As part of my work on the sctplib userland SCTP implementation, I have also 
implemented UDP encapsulation in sctplib. I intensively used it in sctplib-
based RSerPool setups.
