The RSVP protocol is used by routers to deliver quality-of-service
(QoS) requests to all nodes along data flow path(s) and to establish
and maintain state for the requested service. RSVP requests generally
result in resource reservations in each node along the data path.
RSVP has the following attributes:
Makes resource reservations for unidirectional data flows.
Allows the receiver of a data flow to initiate and maintain
the resource reservation used for that flow, as shown in Figure 6.
Maintains a soft state in routers and hosts, providing
graceful support for dynamic membership changes and automatic adaptation
to routing changes.
Depends upon present and future routing protocols, but
is not a routing protocol itself.
Provides several reservation models or styles to fit a
variety of applications.
Supports both IPv4 and IPv6. Note, you can configure the
JUNOS software to tunnel IPv6 over an MPLS-based IPv4 network. For
more information, see the JUNOS MPLS Applications Configuration Guide.
