Cox Communications has expanded deployment of Juniper Networks' gear by installing the company's M320 multiservice edge routers and additional NetScreen security systems.
Cox is deploying 28 Juniper M320s in 14 POPs and NetScreen ISG-2000 systems to support IP/MPLS backbone security and site-to-site VPNs. Cox previously deployed Juniper's M- and T-series routing platforms to support peering, CMTS aggregation, high-speed Internet and video in metro core networks, transparent LAN services, VoIP, video transport and internal IT transport. Cox also uses a range of NetScreen integrated firewall/IPSec VPN products to support the managed security service offered by Cox Business Services, the company's commercial services division.
The M320s will serve as the edge interface between Cisco 12000 series routers in the Cox nationwide core backbone and routers in the cable company's metro area footprints. Three years ago, Cox tapped Riverstone Networks as its metro router supplier but requirements have and are evolving since then, says Randy Kinsey, manager of Network Engineering and Architecture.
"In a lot of these cases, you're reaching the lifetime of some of these boxes as features evolve and utilization increases," Kinsey says. "Riverstone is still being used but not necessarily in all of the same metros that they were originally being used for. Some have evolved into bigger boxes and some of them have been replaced."
Cox says it is replacing its legacy edge routers with the M320s to enhance support for SLAs and network reliability. Kinsey would not say what those legacy routers are but it is believed to be Cisco's 7600 OSR series systems.
Cisco did not comment by press time.
The Cox national IP/MPLS network supports long distance voice traffic and signaling. Cox has over 6.6 million customers.
