Wipro Technologies, the global IT services division of Wipro, has announced the availability of its suite of Multi Protocols Label Switching (MPLS) and Routing Protocols. These ready to use protocol stacks will help the Network Equipment vendors to reduce their development time and accelerate time to market and can be integrated in to the vendor equipment.

The protocol stacks are used in Network equipment like Edge Routers and Switches and use Wipro's Advanced Real-time Multi-platform Adaptive Development Architecture (ARMADA). By using a reusable design block, the customer team starts from a previously synthesized, verified and integrated set of functions reducing overall design time.

Wipro Multi Protocols 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. These are designed to be fully compliant with the IETF RFC's and drafts. These stacks can easily ported to any ROTS/Platform and are designed to interact with any of the routing and forwarding modules.

Features of MPLS include: Supports of downstream, on demand, unsolicited label distribution mechanism, Supports independent and ordered LSP control modes, Supports liberal and conservative label retention mode, Supports basic and extended discovery mechanism, Supports label merging, Loop detection using path vector and hoop counts, Setting of constraint based traffic engineered paths using CR-LDP for Quality of service (QOS) and Class of service (COS), Supports quick and loose explicit routing capabilities with local repair mechanisms and route pinning, CR-LDP uses admission controller and resource manager component for optimum utilization of resources and control LSP admission, Can be used in Label edge router and label switch router, Ipv6 support, COPS interface, Supports RSPV-TE interface, SNMP-MIB support, Works with ATM, frame relay, Ethernet and POS and is available on Linux and VX works. 

The Wipro Routing Protocol Suite includes Border Gateway Protocol (BGP4) and Open Shortest Path First (OSPF) Protocol. Border Gateway Protocol (BGP) is an Exterior Gateway Protocol and is used to carry network reachability information between Autonomous Systems (AS's). Wipro BGP4 is fully compliant with RFC1771. Wipro Open Shortest Path First (OSPF) Stack is designed to be fully compliant with RFC2328. The stack performs routing functionality with the help of configuration information provided by the user.
