Procrastination management manner inside frame relay network and node null of frame relay

摘要

(57) [summary] The present invention relates to a method for managing the congestion of the frame relay network. In this method, a virtual channel associated with (39) the frame to be transferred is determined. In order to provide a congestion management method is reliable, it is possible to respond quickly and allow determine priority virtual connection to the probability of throughput and, each service level for at least some of (a) virtual channel Specify; determined for (15) easily network resources cause congestion, the congestion level having a value of predetermined relationship relative to the value (b) of the service level; the virtual (c) FR frame (39) discard (39) the frame when the (d) the comparison result does not fall within a predetermined value range and; compared with the value representing the congestion level of the resource, the value representing the service level of the channel.
