System and Apparatus of a Software-Service-Defined-Network (SSDN)

A system for software service defined networking (SSDN) environment, comprising:

• a network software service layer (NSSL) service bus in a NSSL, wherein the NSSL service bus comprises a processor;
• a service bus utilities node comprising a plurality of service bus utilities used by the NSSL service bus to manage and control interaction between a plurality of network controllers and a plurality of network switches in a plurality of local networks;
• a plurality of adapters coupling the NSSL service bus to the plurality of network controllers and the plurality of network switches,
• wherein the network controllers determine a path for data to traverse at least one of the local networks via at least some of the plurality of switches,
• wherein the network switches are configured to forward data through the SSDN, and
• wherein the NSSL service bus is configured to provide the network controllers with global network information, such that the network controllers provide end-to-end service routing plane in a global SSDN network comprising the plurality of local networks.

A computer program product executable by a processor in a network software service layer (NSSL) service bus in a software service defined network (SSDN), the computer program product comprising computer executable instructions stored on a non-transitory computer readable medium that when executed by the processor causes the NSSL service bus to perform the following:

• coordinate actions of a plurality of network controllers in the SSDN, wherein at least some of the network controllers correspond to different local SSDNs;
• expose the plurality of network controllers as services addressable by service names;
• extend the local SSDNs into a global SSDN network;
• and
• provide the network controllers with global network information, such that the network controllers provide end-to-end service routing in the global SSDN network.
