Problems solved by technology

However, although on some Cisco TM It is possible in switches to set the broadcast rate to zero, but so far there is no incentive to set the broadcast rate so low, as this would usually result in an unacceptable number of packets being dropped (due to their unknown forwarding addresses)

Abstract

A communications scheme for configuring a network comprising a plurality of connected switching apparatus, each switching apparatus having functionality for implementing connectionless forwarding of received communications traffic to selectively provide a connection-oriented service for said received communications traffic, the scheme comprising: determining in a control plane index header field values to identify connectionless traffic received at switching apparatus for which a connection is to be established between a source node and a destination node; providing each switching apparatus necessary to implement the connection with information from the control plae, the information enabling the data forwarding tables of the switching to be populated with said index header field values in association with egress ports of the switching apparatus; and disabling all other functionality on said switching apparatus capable of populating the data forwarding tables with index information associated with said egress ports of the switching apparatus necessary to establish said connection.

Description

technical field [0001] The present invention relates to a connection-oriented communication scheme for exchanging connectionless traffic over a communication network. The invention relates particularly but not exclusively to switching arrangements configured to implement a connection-oriented communication scheme for said connectionless traffic in said communication network, and such as providing appropriate signaling information and OAM control information to support this Relevant aspects of the method of the communication scheme. Background technique [0002] Communications networks have evolved dramatically over the past few decades from the connection-oriented circuit-switched systems of the past using point-to-point connections to the connectionless digital communications networks available to virtually all businesses and consumers. As a result, there currently exists a mixture of communication systems, each with its own specific characteristics for different types of ...
