Working on cloud based hosted VOIP and unified communication solutions.

The project involved development of the Veraz SIP Session Border Controller (SBC), aimed at delivering comprehensive interactive communication – voice, data, video, multimedia sessions – across IP network borders. The Veraz SBC is modeled in a way that it can act as an SIP ALG for message security, an IMS compliant P-CSCF/I-BCF in the control plane, an A-BGF in the media plane

or any combination of these. The unique architecture of the SEG allows it to be deployed as an Access-SBC and an Interconnect-SBC between peering networks.

The Broadband Service Router (BSR) provides broadband carriers with competitive edge in defining, deploying and managing broadband services.

This carrier-class switching and service provisioning solution allows cable operators to rapidly introduce differentiated data, voice and multimedia services for both corporate and residential subscribers and deliver QoS levels end-to-end from the cable modem to the core network.

Product expertise :

• BSR2000 / BSR1000 / BSR64000 – Cable Modem Termination System (CMTS) variants to cater from small to large scale Multiple Service Operators (MSOs).

Domain expertise

• DOCSIS 1.0/1.1/2.0 – CableLabs specifications - data over cable transmission

• OSPF/RIP/BGP/PIM/IGMP – Unicast / Multicast routing protocols

• PacketCable Multimedia (PCMM)

Key Responsibilities:

• Involved in the first software release for BSR2000 in the areas of routing and policy control. Worked on features such as OSPF, BGP, access-lists, PBR, PIM.

• Implementation of PacketCable Multimedia (PCMM) functionality on BSR2000. Work ranged from initial impact analysis right up to integration testing and field trials.

• Part of a technical council focusing on exploring/following the prospects of WiMax as a next generation access technology
