Current Status: Two formatsGlobal-ID as per RFC5003ITU Carrier Code

Issue:Should these be combinable with all other

identifiers that need global uniquenessOr should some limits exist on mixing and matching

ITU and IP style IDs?Needs to be sorted for ACH-TLV draftBalance of presentation using “SP-ID” as

placeholder without specifying which one(s)

Link InterfaceTunnel Interface

Node IDs◦ 32-bit ID assigned by operator◦ Need not be an IP Address, but◦ Can be auto-generated from an IPv4 address

Interface IDs◦ Logical Interface Handle

32-bit ID that is assigned from a space local to a particular node

◦ IF-ID ::= Node-id::LIH◦ Only needed on tunnels and links

lower ([Sp-ID]::Node-ID) goes first

LSP-num – 16 bit identifier as in RFC3209Unique within scope of tunnel

LSP-ID formed as local{[Sp-ID]::node::Tun-ID::LSP-ID}

+remote{[Sp-ID]::node::Tun-ID::LSP-ID}◦ Canonical Format of LSP-ID

lower ([Sp-ID]::Node-ID) goes first◦ Compatible with GMPLS signaling

MEP – Maintenance Endpoint◦ Management function associated with an Tunnel,

LSP, or PW endpoint MEG - Maintenance entity group

◦ A set of peer MEPs ME - Maintenance entity

◦ A relationship between two MEPs within a MEG A MEP belongs to one and only one MEG A MEP may belong to multiple MEs

This is normal for P2MP objects
