New Cisco edge routers optimized for IPv6 traffic

Cisco this week rolled out two routers designed to allow service providers to migrate to IPv6 and more capably support video, mobility and cloud offerings.

Cisco unveiled the ASR 9922 and ASR 9000v, two extensions to its 3-year-old Aggregation Services Router (ASR) line. The routers feature a new capability for the ASR line called Network Virtualization (nV) designed to allow service providers to blend the network edge, aggregation and access layers into a single logical  router, to simplify operations and accelerate service delivery, specifically for IPv6 applications.

Cisco predicts that by 2015, the number of network-connected devices will be more than 15 billion -- twice the world's population -- and the total amount of global Internet traffic will quadruple. This week's ASR 9000 extensions are intended to allow service providers to address these trends.

For the edge, Cisco introduced the 9922 and two new modules for the chassis-based system -- a two-port 100Gbps Ethernet card and a 24-port 10G Ethernet module. The 9922 is the largest router in the ASR family, at 43 rack units and a 22 slot chassis. Twenty of the slots can be used for line cards, while the other two house a route processor and a fabric card. The chassis can run two router processors for redundancy and seven fabric cards for 6 + 1 redundancy, all operating in active/active nonblocking mode.

The 9922 runs the same IOS XR operating system as the existing ASR 9010 and 9006 systems, and includes the following software features: Ethernet business services such as Layer 2 VPN and L3VPN, IPTV, Content Delivey Networks , and Mobile Backhaul transport networks. Layer 2 and Layer 3 Multicast, IP-over-DWDM, Ethernet OA&M, MPLS OA&M, Hierachical QoS, MPLS Traffic Engineering Fast Reroute, Multichassis Link Aggregation , and Cisco Nonstop Forwarding and Nonstop Routing.

The two-port 100G and 24-port 10G Ethernet line cards can also run in the ASR 9010 and 9006 systems.

For aggregation, Cisco rolled out the 9000v, a 1-RU device that functions as a remote line card for the ASR 9000 or ASR 9922 systems for both collocated and remote deployments. Each 9000v can be located up to 80km away from the host ASR system.

The 9000v supports 44 SFP based 10/100/1000Mbps subscriber ports and four SFP+ based 10G Ethernet network uplink ports. With the 9000v, service providers can offer Ethernet services using individual Ethernet Virtual Connections to carry traffic belonging to a specific service type or end user through the network. EVC-based services can be used in conjunction with MPLS-based L2VPNs and native Ethernet switching deployments.
