RSVP-TE Overview
DC-RSVP
Metaswitch is the leading supplier of MPLS software, including
RSVP-TE and its optical extensions
RSVP-TE is used to establish MPLS LSPs when there are traffic engineering
requirements. It is mainly used to provide QoS and load balancing across the network core, and includes the ability to
control all-optical networks.
RSVP allows the use of source routing where the ingress router determines
the complete path through the network. The ingress router can use a Constrained Shortest Path First (CSPF) calculator to
determine a path to the destination, ensuring that any QoS and Shared Risk Link Group (SRLG) requirements are met. The
resulting path is then used to establish the LSP.
The RSVP optical extensions include the ability to signal optical
wavelengths and shared risk link groups, as well as bandwidth, latency and other link characteristics.
Metaswitch's MPLS software, DC-MPLS, fully supports RSVP-TE, including
its optical extensions. For more information on DC-MPLS, see the link below.
