Data Connection's IP Routing products form part of its suite of IP Routing, MPLS, and VoIP protocol software. This entire suite shares the same architecture and coding standards, so that the individual products can be readily integrated to form complete control-plane solutions.
The IP Routing products share the following architecture.
This architecture supports a wide range of applications, including highly-scaled and distributed architectures, and the use of common RTM and CSPF components provides flexible support of multiprotocol devices.
- The Routing Table Manager, DC-RTM, allows
routing information to be shared between different DCL protocol products, third-party routing
products, and static configuration. DC-RTM manages the combined forwarding table
and the export of routes between protocols, under the control of a policy engine.
- DC-CSPF is the Constrained Shortest Path First calculator, which provides traffic engineering support for DC-ISIS and DC-OSPF. This includes disjoint routes for protection switching and extensions for optical switching.
Distribution Options
The separate components may be distributed onto separate CPUs or line cards. This allows the software to be used in very highly scaled environments, as processing can be distributed.
DC-RTM, DC-CSPF, the DC-BGP Neighbor Manager and the DC-ISIS Subnetwork Dependent components can all be distributed to line cards. In addition, multiple instances of each component can be used for resilience and increased performance.
