3.11.5 RSVP/Packet I/O Interface

3.11.5 RSVP/Packet I/O Interface

An RSVP implementation needs the following support from the packet I/O and forwarding mechanisms of the node.

  • Promiscuous Receive Mode for RSVP Messages

    Packets received for IP protocol 46 but not addressed to the node must be diverted to the RSVP program for processing, without being forwarded. The RSVP messages to be diverted in this manner will include Path, PathTear, and ResvConf messages. These message types carry the Router Alert IP option, which can be used to pick them out of a high-speed forwarding path. Alternatively, the node can intercept all protocol 46 packets.

    On a router or multi-homed host, the identity of the interface (real or virtual) on which a diverted message is received, as well as the IP source address and IP TTL with which it arrived, must also be available to the RSVP process.

  • Outgoing Link Specification

    RSVP must be able to force a (multicast) datagram to be sent on a specific outgoing real or virtual link, bypassing the normal routing mechanism. A virtual link might be a multicast tunnel, for example. Outgoing link specification is necessary to send different versions of an outgoing Path message on different interfaces, and to avoid routing loops in some cases.

  • Source Address and TTL Specification

    RSVP must be able to specify the IP source address and IP TTL to be used when sending Path messages.

  • Router Alert

    RSVP must be able to cause Path, PathTear, and ResvConf message to be sent with the Router Alert IP option.
