CORD: Central Office Reimagined as a Datacenter
Many carriers in both the telecom and cable fields are espousing next generation architectures that borrow heavily from web scale data centers and cloud providers. With this they use SDN and NFV to transform their carrier functions into workloads that are hosted on this common infrastructure. We’ve coined the phrase Central Office Re-architected as a Datacenter (CORD) to refer to this approach of providing infrastructure as a service and networking services as tenant applications for that infrastructure. One application that is a great example of this is broadband access by virtualizing Optical Line Termination equipment (vOLT) as well as Customer Premises Equipment (vCPE) and Broadband Network Gateway (vBNG).
CORD Central Office Re-architected as a Datacenter
CORD re-architects the Telco Central Office as Datacenter to bring in cloud-style economies of scale and agility. It takes today’s proprietary boxes, determines how their functions can be aggregated or disaggregated, and instantiates them on commodity infrastructure.
ON.Lab today announced that a team comprised of AT&T*, ONOS project, PMC-Sierra (Nasdaq:PMCS) and Sckipio will showcase the first public demonstration of the Central Office Re-architected as Data Center (CORD) proof-of-concept (POC) at next week’s Open Networking Summit (ONS2015) in Santa Clara, Calif.
In addition to virtualized network functions such as firewall, parental control, and caching, the CORD demo also includes virtualization of three legacy network devices common to today’s access network — Optical Line Termination (OLT), Customer Premises Equipment (CPE), and Broadband Network Gateway (BNG) — all refactored as software running on (and controlling) commodity servers, white- box switches and merchant silicon I/O blades. The resulting software is then organized as an interconnected set of elastic and scalable services, all managed by open source software — specifically ONOS, OpenStack, and XOS1 — to unify SDN, NFV, and the Cloud under a common, intuitive, carrier-grade framework.
