AT&T deploys disaggregated open routing platform for edge applications

Tuesday 17 November 2020 | 13:34 CET | News

AT&T announced it has deployed an open disaggregated IP edge routing platform in its production environment with support from Broadcom, Cisco and UfiSpace. The hardware platform used for this edge application is identical to that previously announced for AT&T’s IP/MPLS core. 

The identical open hardware from UfiSpace used for the core will be used for the edge applications. Common hardware enables consistent maintenance processes and sparing. 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. 

Cisco’s IOS-XR Network Operating System provides the management and control functions for the platform. Some of the key features for the peering use case are BGP Flowspec, unicast Reverse Path Forwarding (uRPF), and port mirroring which collectively will allow AT&T fine-granular monitoring and mitigation actions for security threats such as DDoS attacks.
