METHOD OF CONTROLLING OSI (ISO) LAYER-TWO LOOPS FOR TELECOMMUNICATION NETWORKS

摘要

The invention relates to a method of controlling OSI (ISO) layer-two loops for telecommunication networks. The invention is characterised by the use of links that are disabled by a standard protocol which prevents the occurrence of loops, for the sending of messages to a single user (unicast) with a known destination. The inventive method can be used to optimise the efficiency of the network with regards to the traffic directed towards a single user between destinations that are connected by means of a medium. In this way, the method can also be used to maintain the objective of any standard loop-prevention protocol which is applied to the system for multicast and broadcast traffic, i.e. traffic which can generate flooding and other problems caused by the loops, while increasing efficiency between switches having links that have been disabled by the standard loop-prevention protocol for unicast traffic.
