Reservation Styles; Rsvp Message Pacing - Alcatel-Lucent 7210 SAS M User Manual

RSVP

Reservation Styles

LSPs can be signaled with explicit reservation styles. A reservation style is a set of control options
that specify a number of supported parameters. The style information is part of the LSP
configuration. SR OS supports two reservation styles:
Note that if FRR option is enabled for the LSP and selects the facility FRR method at the head-end
node, only the SE reservation style is allowed. Furthermore, if a 7210 SAS M PLR node receives a
path message with fast-reroute requested with facility method and the FF reservation style, it will
reject the reservation. The one-to-one detour method supports both FF and SE styles.

RSVP Message Pacing

When a flood of signaling messages arrive because of topology changes in the network, signaling
messages can be dropped which results in longer set up times for LSPs. RSVP message pacing
controls the transmission rate for RSVP messages, allowing the messages to be sent in timed
intervals. Pacing reduces the number of dropped messages that can occur from bursts of signaling
messages in large networks.
