New IP Gear from Cisco

Cisco Systems Inc. is introducing two new major products to its Internet-protocol-based next-generation architecture, both aimed at helping platform providers, including cable companies, to cope with the demands of rising amounts of video on their networks and the coming growth of wireless devices that will perform services like retrieving e-mail from broadband accounts.

One product is an IP dense-wave-division multiplexing platform. The other is a session-border controller and associated media gateway for IP Multimedia Subsystem applications and non-IMS applications.

Cable operators have been delivering on-demand video streams using IP for several years. In most cases, they have installed 10-gigabit DWDM technology to speed those video streams around their metro- and local-area systems.

Cisco’s new IP DWDM platforms allow operators to increase throughputs to 40 GB with the installation of 40-GB ports on to existing 10-GB systems, said Suraj Shetty, director of marketing in Cisco’s routing and service-provider technology group.

The 40-GB ports would allow operators to eliminate the physical transponder layer between their Cisco routers and their reconfigurable add/drop multiplexer systems, Shetty said.

The new session-border controller works alongside Cisco’s “CSR 12000” series router and delivers voice calls for IMS and non-IMS applications. The “MGX 8880” media gateway provides service for wireless, wireline and cable applications.

Historically, cable has not pursued IMS and Session Initiation Protocol applications as they applied to voice applications over the Data Over Cable Service Interface Specification platform.

But reliable SIP applications based on new IMS standards have begun to take hold in wireless-phone marketing, said Peter Clarke, marketing director at Cisco’s service-provider group.

Specifically, cable began to add IMS-type language to PacketCable Multimedia specifications over the past few months.

Cisco’s new session-border-control product is both a network card that can be inserted into the vendor’s existing “CSR 12000” routers and associated software to run new IMS-type applications.
