Aricent’s comprehensive SDN controller applications suite provides an array of network services such as routing services, operations, administration, and maintenance (OAM), traffic steering, lawful intercept, and route optimization. The controller applications can be ported across various controller platforms.
Routing Service ApplicationTraditional routing protocols BGP and OSPF are run as Virtual Routing Engine (VRE) on the controller. VRE provides a logically centralized control plane separated from the forwarding switches. It enables optimized routing services such as computation of shortest path and application aware routing. The benefits of the centralized control plane include better view of the network traffic and flexible, intelligent and traffic engineered route control. This improves the network operations, leading to better utilization of network resources.
OAM for Carrier NetworksOpenFlow protocol does not have provision for fast failure detection at transport level. While this is acceptable in data center networks, same may fall short in carrier networks. To bridge this gap, Aricent’s widely deployed OAM Frameworks for carrier networks – Ethernet OAM IEEE 802.1ag and ITU-T Y.1731 are re-purposed as controller applications, rendering efficient OAM in carrier networks.
