United States : Breakthrough Elastic Cloud-to-Cloud Networking Unveiled by AT&T, IBM Research and ACS

July 30, 2014



Scientists from AT&T, IBM and Applied Communication Sciences (ACS) announced a proof-of-concept technology that reduces set up times for cloud-to-cloud connectivity from days to seconds. This advance is a major step forward that could one day lead to sub-second provisioning time with IP and next generation optical networking equipment and enables elastic bandwidth between clouds at high connection request rates using intelligent cloud data center orchestrators, instead of requiring static provisioning for peak demand.

The prototype was built with contributions and expertise from AT&T, IBM and ACS, and the work was performed under the auspices of the U.S. Government s DARPA CORONET program, which focuses on rapid reconfiguration of terabit networks. The program was visionary in anticipating the convergence of cloud computing and networking, and in setting aggressive requirements for network performance in support of cloud services said Ann Von Lehmen, the ACS program lead.

AT&T was responsible for developing the overall networking architecture for this concept, drawing on its industry leadership in bandwidth-on-demand (BoD) technologies and advanced routing concepts. IBM provided the cloud platform and intelligent cloud data center orchestration technologies to support dynamic provisioning of cloud-to-cloud communications. ACS contributed its expertise in network management and innovation in optical-layer routing and signaling as part of the overall cloud networking architecture.

Cloud computing already has widespread impact across how we access today s applications, resources, and data. Today s traditional cloud computing model is built on the premise of automation and lower operational costs, which requires dynamic provisioning of resources. However, the traditional cloud-to-cloud network is static and creating it is labor intensive, expensive and time consuming.

In response to the rapid advent of cloud-based services and explosion in data center size and scope, Cloud Service Providers (CSPs) have installed automatic and intelligent resource management systems within their data centers. For example, these systems can load balance both processor and storage resources, as well as perform massive transfers of data among multiple data centers.

These shifts have driven the need to develop rapid and high rate bandwidth-on-demand in the Wide Area Network (WAN), said Robert Doverspike, executive director of Network Evolution Research at AT&T Labs. By combining software defined networking (SDN) concepts with advanced, cost-efficient network routing in a realistic carrier network environment, we have successfully demonstrated how to address this need.
