In general, a communication network provides the capability to selectively forward (transport) information between access points. The capacity (of the network) is shared amongst the users of the network. The shared capacity is formed by a recursion of elements of capability some of which aggregate capacity and some of which partition capacity (ie.eg., allocate some dedicated portion of the capacity to a particular user).

The key concepts are summarized below:

Generalized Constraint:

  • Constraint Domain (CD)A general : Is a general grouping, scoping and constraining conceptcapability.
    • It is used to group representations of functionality (network, control etc.) such that constraints can be applied to the group if required.
      • The detailed constraint model is under development.
    • It is used to group representations of physical things.
    • Constraint Domains can be related, or they may be for different purposes, they can overlap and they don't need to form a hierarchy.

Generalized Control:

  • Control Construct (CC)A Control Construct processes : Represents a function that processes information to control other network functions (such as Processing Constructs, Forwarding Constructs, Control Constructs etc.).

Generalized Network Transport structure and functions:

  • A Forwarding Domain (FD) represents : Represents a switching/routing function. It constrains transport of information by constraining enclosed Forwarding Constructs, Links and other Forwarding Domains, by limiting their extent and connections to LTP.
  • A Link represents : Represents adjacency between FDs provided by server layer capability. It constrains the creation of Forwarding Constructs between two or more Forwarding Domains (FD), by associating a set of LTP on one FD with an equivalent set of LTP on another FD.
  • A Forwarding Construct (FC) represents : Represents the transport of information (forwarding) between its ports.
  • Logical Termination Point (LTP) and Layer Protocol (LP). LTP provides a common place to represent the termination of protocol layer information and the adaption between protocol layers. LP provides a place to represent protocol layer specific information within the LTP.

Generalized Processing:

  • A Processing Construct (PC): Represents any function that takes information arriving at one or more of its ports, processes it and then sends it out of one or more of its ports.

Telecoms focused Physical:

  • Equipmentrepresents: Represents, for example, a circuit pack; a rack; an SFP etc. only from the perspective of its physical structure. A piece of equipment may support one or more functional resources (as described above).
