Thinking about the solution… Routing Add 2 bits, one for vcat capability, one for lcas capability of a TE link Signaling We need to tell how big the group is (VCAT) or is going to be (LCAS)? May need to know in advance so we don’t set up 60 and choke at #61 We need some VCAT group id, possibly use association id List of extra error codes we thought of: Be able to refuse the 1st one Be able to refuse subsequent ones: no more Alarm such as signal label mismatch (mapping scheme, e.g. GFP, LAPS) should also be communicated as an error code Inter-domain boundaries May need to terminate association at the boundary and restart a new one |
