AT&T Submits White-Field Router Spec for Open Computing

AT&T submitted specs for a brand new white-box structure to the Open Compute Undertaking (OCP), concentrating on service provider-class routers with chips optimized for 400 gigabits per second (400G) speeds to satisfy evolving community calls for.

These calls for consequence from new applied sciences corresponding to 5G and fiber-based broadband providers.

To fulfill these rising calls for, AT&T’s spec incorporates a Distributed Disaggregated Chassis (DDC) design, prominently that includes 400G Jericho2 service provider silicon chips from Broadcom.

Assembly rising calls for is a part of the mission assertion of the OCP, which describes itself as “a collaborative neighborhood targeted on redesigning {hardware} know-how to effectively help the rising calls for on compute infrastructure.”

To help that mission, the AT&T spec gives a brand new tackle the normal modular chassis design for high-capacity routers, incorporating stand-alone white bins that bundle previously separate gear playing cards that supplied elements for energy provides, followers and controllers.

The three key constructing blocks for the brand new white field design have been listed as:

  • A line card system that helps 40 x 100G consumer ports, plus 13 400G fabric-facing ports.
  • A line card system that help 10 x 400G consumer ports, plus 13 400G fabric-facing ports.
  • A cloth system that helps 48 x 400G ports. A smaller, 24 x 400G cloth programs can also be included.

4 typical DDC configurations have been introduced as:

  • A single line card system that helps four terabytes per second (Tbps) of capability.
  • A small cluster that consists of 1 plus 1 (added reliability) cloth programs and as much as four line card programs. This configuration would help 16 Tbps of capability.
  • A medium cluster that consists of seven cloth programs and as much as 24 line card programs. This configuration helps 96 Tbps of capability.
  • A big cluster that consists of 13 cloth programs and as much as 48 line card programs. This configuration helps 192 Tbps of capability.

“The discharge of our DDC specs to the OCP takes our white field technique to the subsequent stage,” stated AT&T exec Chris Rice. “We’re getting into an period the place 100G merely cannot deal with all the new calls for on our community. Designing a category of routers that may function at 400G is important to supporting the huge bandwidth calls for that can include 5G and fiber-based broadband providers. We’re assured these specs will set an trade normal for DDC white field structure that different service suppliers will undertake and embrace.”
