Thomas, This makes a lot of sense to me. My recommendation is to add a "ASAP Transport Param" field to the PE parameter that is a full SCTP transport TLV. Simply adding a SCTP port number field may be too restrictive since some PEs may want to use a separate NIC for its ASAP communications. regards, -Qiaobing Thomas Dreibholz wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Dear all, > > when a NS takes over the ownership of PEs owned by a failed NS, it sends an > ENDPOINT_KEEP_ALIVE message to each of the PEs which change their ownership. > As defined in KA2.4 of section 3.4 of the ASAP draft, the PE should adapt the > sender of an ENDPOINT_KEEP_ALIVE message as its new NS. > > But, how does the new NS know the PEs' ASAP endpoint, that is especially the > SCTP port number the PE is listening on for ASAP ENDPOINT_KEEP_ALIVES?
