management of a packet switching network load, virtual network fragmentation, data routingAbstract
The problems of network load management for a generalized version of a large packet switching network are investigated. The network is divided into elementary fragments according to the selected rule. Data routing is "flat" (not hierarchical). Abstraction is used - a set of network fragments can be represented as a set of networked elements. For each fragment, a significant indicator of its load (for example, the average load of its nodes or another) is defined. The limit of this indicator is set, which provides the definition of an elementary fragment as a fragment with an increased load. In the entered imaginary "network of fragments" there are connected groups of fragments with the increased loading. For groups of elementary fragments with high load, modifications of the load control method are used due to the choice of the lowest cost paths, in which the routing takes into account the node's belonging to the fragments with high load.
