拥塞通知 meaning in Chinese
becn
fecn
Examples
- Backward explicit congestion notification , becn
后向显式拥塞通知 - Becn backward explicit congestion notification
反向显示拥塞通知 - Because internet is based on the bandwidth statistical multiplexing principle so there are lots of active flows competing limited bandwidth resource in a link . when network congestion occurs aqm must send congestion notification to adequate sources to reduce the traffic load and avoid queue overflow
由于互联网是基于带宽统计复用的，一条链路上有很多活跃流( activeflows )在竞争有限的带宽资源，因此，进行拥塞通知时应充分考虑到瓶颈链路上流的数量，而red算法并没有考虑到这一点。 - When the traffic load becomes heavy mred increases the value of maxp , and on the other hand when the traffic load becomes light mred decreases the value of maxp , and therefore mred can effectively adjust the congestion notification sending rate and stabilize the queue size . the differentiated services architecture , proposed by the ietf diffserv working group has recently become the preferred service model for addressing qos issues in ip networks because of its simplicity and scalability
当tcp连接数很大也就是拥塞程度严重时需要采用激进的方法，也即增大max _ p的值；当tcp连接数较小也就是拥塞程度较轻时需要采用保守的方法，也即减小max _ p的值；从而及时调整向源端发送拥塞通知的速率，维持队列长度的稳定，避免不必要的传输延时和抖动。
