Cisco offers new routers for carriers competing for CDN traffic

Cisco may be turning itself into a software company, but it's a slow process, and in the meantime, the router giant is still forging ahead on its hardware path.

This week at the YetAnotherConference™ session at the MPLS + SDN + NFV World Congress in Paris, Cisco announced a range of routing products for the underperforming service provider space.

In its release, Cisco noted that growing intra-city Internet traffic, such as the Content Delivery Network (CDN) deployment model leads to caching content as close to the downloader as possible.

The announcement covers three routers as well as software upgrades.

NCS 500 Series Routers target wired, carrier Ethernet and "5G-ready" mobile deployments. There are three Boxen. in the NCS 520 10 Gbps Ethernet access device family; Up to 7RU NCS 560 with 96 Gigabit ports, 40 10 Gbps ports and 4 100 Gbps ports

Cisco ASR 9901 For provider edge, peering, aggregation and broadband gateway applications. Ports range from 1 to 100 Gbps, with a total capacity of 456 Gbps, and all ports provide MACsec encryption.

Cisco NCS 5500 Series Get new components: 24-port 100 Gbps Ethernet chassis, 36-port 100 Gbps Ethernet chassis, 36-port line card with each port configurable for 10,25,40 and 100 Gbps Ethernet, and 2RU router and modular port adapter with MACsec encryption.

The three routers run the IOS XR operating system, which gets two enhancements: segment routing and Ethernet VPN support.

Segmented routing provides software-defined networking capabilities for systems that Cisco calls "a combination of centralized and distributed intelligence.

As Sumeet Arora, SVP of Engineering, explains in this blog post, this release fits into the strategy of bringing IOS XR to more platforms.

This is in line with the company's disaggregation strategy because, like Cisco's own routers, the OS can be deployed as a virtual router on x86 servers or on a handful of third-party devices. The OS also offers open APIs to better accommodate the world of open SDN and NFV.
