Wipro Multi Protocol Label Switching
(MPLS) solution includes Label Distribution Protocols
(LDP and CR-LDP) and Resource reSerVation Protocol(RSVP-TE).
These stacks provide a signaling mechanism to
set-up Label Switched Path (LSP)across the MPLS
networks. They are designed to be fully compliant
with the IETF RFC’s and drafts. These stacks
can be easily ported to any RTOS/Platform. These
stacks are designed to interact with any of the
routing protocols and forwarding modules.
Features:
 |
Supports
Downstream on-demand and Unsolicited label
distribution mechanisms |
|
Supports
Independent and Ordered LSP control modes |
|
Supports
Liberal and Conservative label retention modes |
|
Supports Basic
and Extended Discovery mechanism |
|
Supports Label
Merging |
|
Loop detection
using Path Vector and Hop Counts |
|
Setting of
Constraint based Traffic Engineered paths
using CR-LDP for Quality of Service (QoS)
and Class of Service (CoS) |
|
Supports Strict
and Loose explicit Routing capabilities with
local repair mechanisms and Route Pinning |
|
CR-LDP uses
Admission Controller and Resource Manager
component for optimal utilization of resources
and control LSP admission |
|
Can be used
in Label Edge Router (LER) and Label Switched
Router (LSR) |
