光突发交换网络中的主动拥塞控制策略

An active congestion control mechanism in OBS networks

提出了光突发交换网络中一种主动拥塞控制策略,详细讨论了该策略的具体实现过程。该策略将拥塞控制从用户端扩展到光突发交换网络的边缘节点,不仅能对网络中的拥塞及时地作出主动的响应,同时迅速重传丢失的数据,克服子网中的准同步现象和减少不必要的数据重传,从而改善整个OBS网络的性能。

This paper proposes an active congestion control mechanism in OBS networks,and expounds the realization process of it in details.This mechanism extends congestion control from the users to the edge nodes of OBS networks, responds to congestion in time,and retransmits the dropped data quickly. The mechanism can reduce the retransmission of the dropped data and avoid the phenomenon of semi-synchrony of subnet, so it enhances the performance of OBS networks.
