AT&T, the third largest mobile operator in the United States in terms of subscribers, has deployed a next-gen open dis-aggregated IP edge routing platform with support from Broadcom, Cisco, and UfiSpace.
The hardware platform being used for this edge application is identical to that previously announced for AT&T’s IP/MPLS core, AT&T said.
“The first IP edge use case is peering – the system that connects AT&T’s IP network with that of other Internet Service Providers (ISPs),” said Andre Fuetsch, AT&T’s CTO for Network Services. “We work with Cisco on developing additional edge use cases that will include broadband, IP content, Ethernet, mobility, and VPN services.”
The identical open hardware from UfiSpace that is being used for the core will be used for the edge applications.
The Broadcom Jericho2-based hardware designs have been accepted by OCP, and compatible products are available from other ODMs. The UfiSpace portfolio consists of three components: a 40x100G line card system, 10x400G line card system, and a 48x400G fabric system.
These building blocks are deployed using the Distributed Dis-Aggregated Chassis (DDC) design in various configurations to build routers with capacity anywhere between 4 Tbps to 192 Tbps, said Ram Velaga, senior vice president and general manager, Core Switching Group, Broadcom.
Cisco’s innovative IOS-XR Network Operating System provides the management and control functions for the solution.
Some of the features for the peering use case are BGP Flowspec, unicast Reverse Path Forwarding (uRPF), and port mirroring which will allow AT&T fine granular monitoring and mitigation actions for security threats such as Directed Denial of Service (DDoS) attacks, Jonathan Davidson, SVP and GM, Mass Scale Infrastructure Group, Cisco, said.
