Multicast Extensions to OSPF
Multicasting Extensions to OSPF (MOSPF) enhances the OSPF protocol by
providing capabilities that allow a router to forward multicast IP traffic within an
OSPF Version 2 autonomous system.
For instructions on configuring MOSPF, see Cha
pter 5.
Quality of Service Extensions to OSPF
QOSPF is an extension of OSPF and MOSPF that works in conjunction with the
Resource Reservation Protocol to provide quality of service (QoS) for multicast
data flows.
QOSPF is described in Cha
pter 6.
Resource Reservation Protocol
The Resource Reservation Protocol (RSVP) allows host systems in an IP network
to reserve resources on RSVP-capable routers for unicast or multicast dataflows.
(A dataflow is a transmission of packets from a source to one or more destinations
requiring a certain QoS.)
RSVP is described in Cha
pter 7.
Bay Networks Resource Manager
The Bay Networks Resource Manager lets you define a certain percentage of a
line’s bandwidth as reservable. Applications that require a guaranteed quality of
service can negotiate for the reservable bandwidth. When the router honors a
reservation request, the Resource Manager allocates bandwidth from the
reservable bandwidth, reducing the bandwidth available for other requests.
For information about the Bay Networks Resource Manager, see Cha
pter 8.
