Mobile-CORD Overview
The figure below describes the high level architecture of M-CORD.
As seen above:
• The entire solution runs on open compute hardware – Radisys' DCEngine™ which is compliant to the OCP-
ACCEPTED CG-OpenRack-19 specification.
• The data center is typically comprised of leaf and spine connectivity and commercial off-the-shelf (COTS) servers.
• It follows a micro-service architecture wherein the control and user plane are segregated and services are
instantiated on top very easily.
Other features include:
Virtualized Infrastructure Manager – The CORD platform uses OpenStack as its infrastructure manager which
provides all the infrastructure support such as networking, computing and storage via its various modules – Nova,
Neutron, Ceilometer, Glance, Cinder, etc. This captures the cloud context of M-CORD.
So ware-Defined Network (SDN) – The M-CORD platform uses the open source SDN controller ONOS to control
the user plane traffic and the tenant networking on the platform.
Virtualized Network Function (VNF) – within M-CORD, the network functions are MME (Mobility Management
Entity), SGW (Security Gateway) and PGW (Packet Gateway) which all run on virtual machines. Also, the VNF includes
a virtualized baseband unit for the RAN access side. The EPC VNFs are all split across control and user planes, and
the user planes are controlled over OpenFlow by the ONOS controller.
