摘要： A communications network has means for interconnecting a user computer terminal to a further computer terminal, which further computer terminal is one of a plurality of computer terminals connected in the network. To achieve this a virtual message path is established from the further computer terminal to the user computer terminal in response to an open message sent form the user computer terminal to a user router which sends a service request to the further computer terminal via one or more further routers. Typically the communications network will be the Internet or a similar service.

摘要： In an ATM network, traffic can be self-regulated to avoid congestion by a method where the "congested" indication provided for in the Payload Type field of the standard cell format is set by a switch when the size of queues provided in the switch to statistically multiplexed switched inputs onto output ports suggests the approach of congestion and where the said "congested" indication is subject to a check at the receiving port of the network and a message is sent to the source port if the proportion of cells carrying the "congested" indication on a particular channel is relatively high and where, on receipt of such a message, the permitted bandwidth of the channel is reduced and, if no congestion messages are received over a specified period the permitted bandwidth is increased, said reduction and increase of bandwidth being in small increments between absolute limits.
摘要翻译：在ATM网络中，流量可以被自我调节以避免拥塞，其中当交换机中提供的队列的大小为切换到设置的队列的大小时，由交换机设置标准小区格式的有效载荷类型字段中提供的“拥塞”指示在输出端口上的统计复用的交换输入表明拥塞的方法，并且其中所述“拥塞”指示在网络的接收端口进行检查，并且如果携带“拥塞”的小区的比例的信息被发送到源端口在特定信道上的指示相对较高，并且在接收到这样的消息时，减少了信道的允许带宽，并且如果在指定周期内没有接收到拥塞消息，则允许带宽增加，所述减少和增加带宽在绝对限制之间以小增量。
