AT&T today announced some enhancements to its Network on Demand, this time naming some specific vendors participating — Brocade, Cisco, and Juniper Networks.

AT&T designed virtual customer premise equipment (vCPE) with Juniper and has been working with Brocade to enable routing functions to be delivered from the cloud. With Cisco, the carrier is collaborating on two fronts: vCPE and on-demand services for business customers.

Network on Demand was introduced a year ago and rolled out to 100 markets by April. It's an example of the way AT&T is trying to work with a broader range of vendors on software defined networking (SDN) and network functions virtualization (NFV) to create more dynamic on-demand services.

Juniper's software-based vCPE, designed to AT&T's specifications, enables business customers to run multiple virtual functions on one device with no new hardware.

With Brocade, AT&T has created a new on-demand Managed Internet Service to deploy virtualized access routers and streamline Internet setup for business customers. With the Brocade vRouter, control is automated in AT&T’s core network for enterprise customers to adjust and add capabilities in near-real time. Customers don't need a router at their location, and they are able to order more ports, add or change services, and adjust bandwidth at will.

Managed Internet Service on Demand will be available in select U.S. cities later this fall.

Finally, AT&T noted Cisco is also part of its vendor group working on NFV and SDN, bringing a portfolio of over 100 virtualized network function (VNF).

Today’s announcements stem from the carrier’s recent work to roll out its AT&T Switched Ethernet Service, which is deployed in more than 170 U.S. cities and for which it has signed more than 200 customer contracts. In conjunction with the switched Ethernet initiative, AT&T announced Network on Demand in September 2014 as a way to simplify and speed the provisioning of network services for businesses.
