The Signaling and Traffic Engineering development kits as described in MARBEN™ GMPLS Suite are very flexible, and can be used to accommodate a wide range of MPLS, OIF or GMPLS-based applications. However, they require a significant development effort from the MARBEN™ Products customer to build a complete application on top of these development kits.

The MARBEN™ GMPLS controllers are a set of high-level libraries built on top of the Signaling and Traffic Engineering development kits. Such controllers are intended for MARBEN™ Products customers that are willing to trade off some flexibility against faster GMPLS application development and integration. These controllers provide GMPLS and GMPLS-based (OIF/ITU-T UNI and E-NNI) signaling and routing procedures.

It consists of three different controllers:

• the Signaling controller
  • mainly manages Setup and teardown of calls and connections. It invokes services from the Routing Controller and the Link Resource manager to achieve such a goal.
• the Routing controller
  • mainly manages Path computation capabilities using the traffic engineering information running IS-IS or OSPF routing protocols.
• the Link resource manager
  • performs local TE-Links management.
