Abstract: Exemplary methods for updating an application programming interface (API) that includes a first set of functions and a first set of data types, includes determining a new software version has been installed, wherein the new software version requires the API to include a second set of functions and a second set of data types. The methods include determining a set of common functions and a set of common data types, wherein the set of common functions includes functions that are common between the first set of functions and the second set of functions, and wherein the set of common data types includes data types that are common between the first set of data types and the second set of data types. The methods include sending the set of common functions and the set of common data types, and calling the API, causing the set of common functions to be performed.

Abstract: An Enhanced Service Layer Mapping which is hierarchical and widely load balanced to derive an efficiently distributed architecture. At the top of the hierarchy, all the ports are grouped into SPG units and tightly coupled with the SSS unit. At the second level of the hierarchy, within a given SPG-SSS unit, the ports and subscribers are sub-grouped and tied to a sub-pool of PEs. At an even lower level of the hierarchy, subscribers and services are mapped and load balanced to a fixed PEs.
