Voice/data switch uses advanced Linux routing software

Apr 28, 2004 — by LinuxDevices Staff — from the LinuxDevices Archive — 2 views

Telecom equipment vendor Giga Stream says it uses IP Infusion's ZebOS Advanced Routing Suite (ARS) in a unique embedded Linux based “Universal Navigation Switch” (UNS) that integrates voice, data, and radio access to support seamless subscriber roaming between Radio Access Networks (RANs) and Wireless LANs.

Giga Stream's “Universal Navigation Switch” provides connectivity, network control, and interworking between converged voice/data networks and GPRS/3G/WLAN wireless networks, according to Giga Stream. It targets mobile and fixed operators wishing to support 3G, WLAN, and high-performance IP packet transmission capabilities in a single device, and to migrate from today's TDM / ATM transport towards an all-IP environment.

IP Infusion describes its ZebOS Advanced Routing Suite (ARS) as a sophisticated, robust, and standards-based Layer 2 and Layer 3 carrier-class routing and switching software package supporting IPv4, IPv6, Multicast, and MPLS/Traffic Engineering protocols.

IP Fusion first demonstrated the interoperability of ARS with MontaVista Linux — on which the UNS is based — in October of 2002. The UNS will use a number of the routing and switching protocol modules available in ARS, including BGP-4+, OSFPv2 with Traffic Engineering, IS-IS with Traffic Engineering, RSVP-TE, and an MPLS Forwarder.

"IP Infusion enabled us to enhance the delivery of value-added IP Services. The separation of forwarding and routing elements substantially changes the architecture of Next Generation Networks and reduces operational expenditures -- a clear benefit for our customers,” said Thomas Maul, Giga Stream founder and CEO.
