MPLS-OpenFlow based access/aggregation network

SPARC: Split architecture carrier class Networks

• Enhance control flexibility by Breaking OUT Intelligence to CENTRALIZED Controller

• Interact with Distributed MPLS control Plane VIA legacy Protocols

• OAM & Protection Functions IMPLEMENTED IN DATA Plane to Off-load centralized controller

Demo Includes• MPLS OPENFLOW CONTROLLER for Best effort Point-

to-Point and multicast traffic

• SEAMLESS INTERWORKING WITH MPLS CONTROL PLANE

• ESTABLISHMENT OF BFD Monitoring in OpenFLOWDomain

• OPENFLOW Controller driven RESTORATION AND data plane triggered protection

Monitoring and Protection RUN in Data Plane

• Working & Protection Label Switched Paths (LSP) monitored with Periodic probe packets (BFD)

• Client LSP mapped TO working LSP via Virtual Ports

• When working LSP goes down client LSP IS Automatically RE-Mapped to THE Protection LSP

Split Architecture: OpenFlow based MPLS access/aggregation network – DEMONSTRATOR András Kern, Zoltán Lajos Kis, Dávid Jocha, Attila Takács – Ericsson Research Pontus Sköldström, Viktor Nordell – Acreo AB E-mail: andras.kern@ericsson.com

The "Split architecture carrier grade networks" (SPARC) 7th framework EU project(http://www.fp7-sparc.eu/) aims at designing and prototyping a scalable control planesolution for public networks by splitting the control and forwarding functions. This isdone by the use of an open interface between a centralized controller and a set offorwarding elements. The focus use-case is an MPLS based access and aggregationnetwork and the inter-working with IP/MPLS based core network. Making use of open-source components, our proof-of-concept prototype demonstrates a semi-centralizedcontrol scheme, where a centralized controller manages an MPLS based aggregationdomain and seamlessly inter-works with a legacy distributed MPLS core network.

In our demo we show (i) the connectivity setup across OpenFlow aggregation and the core IP/MPLS network, utilizing the OSPF and LDP protocols, (ii) a multicast video streaming with dynamic subscription/un-subscription and optimal transmission tree recalculation, and (iii) LLDP based controller driven restoration versus BFD based data plane managed protection.

Our NOX OpenFlow controller and Linux based soft-switch implementation of OpenFlow 1.1 will be available open-source. Please send request for more information to andras.kern@ericsson.com.
