…-1 Carrier Routing System. In 2004, Sprint and Cisco used CRS-1 routers to conduct the first 40-Gbps technology trial with live-production traffic. Sprint began deploying them in its IP core network in 2006. Today, Sprint CRS-1 routers are deployed in more than 25 U.S. cities, and Sprint is working to…

…Initially, Cisco and Ciena will work to enable service providers to build high-capacity IP backbones by interfacing the Cisco 12000 Gigabit Switch Router (GSR) directly to Ciena?s long-haul, dense wavelength division multiplexing (DWDM) systems. The Cisco 12000 will interface with Ciena?s DWDM systems…

…Synchronous Ethernet, and IEEE 1588v2* over Gigabit Ethernet (GbE) or 10GbE trunk interfaces for cost-effective interworking with Ethernet switches and routers. Also, the enhanced traffic management capabilities guarantee end-to-end performance during congestion and protection scenarios. The switches provide…

…Gigabit Ethernet (10GbE) connectivity to subscriber edge and first-tier aggregation switches, and high-performance 10GbE uplinks to IP/MPLS core switch/routers. With its 1 Tb/s full duplex capacity today, the system can easily accommodate future line modules that will offer 100GbE interfaces. The 5410 architecture…

Monday, March 5, 8:00-11:00am PST | 408B Denis Morgen, Senior Director, Sales The Road to the…

Mitch Auster discusses how Ciena's core router offload solution decosts the network while allowing it to scale-enabling profitable bandwidth and revenue growth.

…Router Redundancy Protocol (VRRP) A non-proprietary redundancy protocol designed to increase the availability of the default gateway servicing hosts on the same subnet. This increased reliability is achieved by advertising a "virtual router" (an abstract representation of master and backup routers…

…synchronization includes both Synchronous Ethernet and IEEE 1588v2 over GbE trunk interfaces for cost-effective interworking with Ethernet switches and routers. These switches provide Ethernet access (10/100 RJ-45), Structure Agnostic TDM access (T1/E1 - SAToP), Structure Aware TDM access (nxDS0/E0 &ndash…

…today. ``Optical service providers are demanding backbone routers that scale with network growth and provide simple IP-over-glass connectivity,?? said Joe Furgerson, vice president of marketing for Juniper Networks. ``We designed the M40 Router to provide both full wire rate performance at OC-48 at Layer…

…provide network operators up to a 50% reduction in the cost of connecting routers to the optical network vs. the legacy Packet-over-SONET (POS) alternative. In addition to interface cost savings, deploying CoreDirector FS for router interconnect provides the following additional benefits to service providers…
