RFC 3209 RSVP-TE Session Attribute without resource affinities Object

The Session Attribute Class is 207. Two C_Types are defined, LSP_TUNNEL, C-Type = 7 and LSP_TUNNEL_RA, C-Type = 1. The LSP_TUNNEL_RA C-Type includes all the same fields as the LSP_TUNNEL C-Type. Additionally it carries resource affinity information. The formats are as follows: 4.7.1. Format without resource affinities SESSION_ATTRIBUTE class = 207, LSP_TUNNEL C-Type = 7 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Setup Prio | Holding Prio | Flags | Name Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | // Session Name (NULL padded display string) // | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Setup Priority The priority of the session with respect to taking resources, in the range of 0 to 7. The value 0 is the highest priority. The Setup Priority is used in deciding whether this session can preempt another session. Holding Priority The priority of the session with respect to holding resources, in the range of 0 to 7. The value 0 is the highest priority. Holding Priority is used in deciding whether this session can be preempted by another session. Flags 0x01 Local protection desired This flag permits transit routers to use a local repair mechanism which may result in violation of the explicit route object. When a fault is detected on an adjacent downstream link or node, a transit router can reroute traffic for fast service restoration. 0x02 Label recording desired This flag indicates that label information should be included when doing a route record. 0x04 SE Style desired This flag indicates that the tunnel ingress node may choose to reroute this tunnel without tearing it down. A tunnel egress node SHOULD use the SE Style when responding with a Resv message. Name Length The length of the display string before padding, in bytes. Session Name A null padded string of characters.
