Central Office Re-architected as Datacenter (CORD) Solution POC
CORD is a solution POC driven by a team comprised of AT&T, ON.Lab, ONOS Project, PMC-Sierra and Sckipio that aims to bring datacenter economies of scale and cloud-style agility to service provider networks.
is an end-‐to-‐end solu1on POC that combines SDN, NFV, Cloud with commodity infrastructure and open building blocks to deliver datacenter economies of scale and cloud-‐style agility to service provider networks 3 CORD Value proposiAon 4 CORD open building blocks ONOS(SDN Control Plane), Openstack(Virtual infrastructure mgmt), XOS (Services mgmt), open commodity hardware, OF-‐enabled OLT MAC and G.fast DPU CORD enables service providers to build an underlying common infrastructure in Central Office with white boxes, ONOS, OpenStack, and XOS with a diversity of organiza1ons building the services and solu1ons above. CORD Highlights
of CAPEX/OPEX Problem: Today’s Telco Central Offices (COs) are huge source of CAPEX/OPEX • Fragmented non-‐commodity hardware. • Physical install per appliance per site • Nearly 300+ unique deployed appliances. BNG Firewall DPI CDN Message Router Carrier Grade NAT Session Border Controller PE Router SGSN/GGSN/ PDN-‐GW Source: AT&T and their design/infrastructure is not geared for programmability, agility What’s needed? Common underlying infrastructure based on commodity hardware/whiteboxes and open pla\orms
of SDN/NFV/Cloud Broadband Network Gateway Eth Agg OLT 10 GigE (LAG) PON Spli^er CPE CPE ONT ONT Phone Phone STB w DVR STB w DVR PC PC Telco Central Office Subscriber home 2.5 Gb/s 1.25 Gb/s What’s needed? An End-‐to-‐end solu1on that spans CPE, diversity of access(GPON, G.fast etc) and Central Office to get maximum benefits of SDN/NFV/Cloud Source: AT&T 300+ appliances (Firewall, DPI, CGNAT..) Subscriber home
solu1on POC that spans Telco Central Office, Access (GPON, G.fast..), Home/Enterprise • combines SDN, NFV, Cloud with commodity infrastructure and open building blocks to deliver datacenter economies of scale and cloud-‐style agility to service provider networks • enables service providers to build an underlying common infrastructure in Central Office with white boxes, ONOS, OpenStack, and XOS with a diversity of organiza1ons building the services and solu1ons above. • proof-‐of-‐concept solu1on will be demonstrated at ONS 2015
