Dynamic Systems Network Architecture Resource Allocation and Address Assignment

This article discloses a structure which permits dynamic allocation of network resources and network address space in a communications network.

A communications network can be viewed as a finite set of information source/sync nodes with each node identified by a unique network address. The network address space can be divided into equal, fixed size subareas, and any network node is then identified by the concatenation of a subarea address with an element address. The communications network may consist of one or more domains, each having network manager programs at a system services control point (SSCP). Groups of subareas are assigned to each domain, and specific subarea addresses are permanently assigned to subarea physical units (SPU). Each subarea physical unit is computer programmed to dynamically allocate or de-allocate the element address portion of a network node address to each resource. Because new devices must be disconnected, or additional devices connected, to a subarea computer, it is desirable to permit network addresses to be allocated to these devices dynamically by the subarea computer upon request from the network operator. New network resources may be introduced into the network and/or existing ones removed while the network is in operation.

To dynamically allocate resources, the domain SSCP has a data set, including a network resource profile, for each defined resource.

The profile is created by a DEFINE command entered by the network operator while the network is in operation. The defined parameters consist of a unique symbolic resource name, the domain name, the resource name of the owning resource, and the hardware addresses necessary for link/terminal connection. After being defined, the resource can be activated by the network operator simply by the symbolic name. Deactivation/deletion is accomplished in the same way, by name and the DELETE command. The deactivate process frees the network resource address space, which may then be reallocated to another network resource during its subsequent activation. Having defined the resources of the network in the profile data set, the resource can be activated by the network program. The activate process essentially allows the network resource (NR) to participate in the network by allocating a network address element and the network control block (NRCB) for the resource. The NRCB describes the resource to the network manager (NM) and consists of profile data and NM generated information, such as NR status.
