Abstract

In order to achieve better scalability, inter-domain signaling protocols rely on aggregation to reduce the amount of state information that routers are required to maintain. Nonetheless, they do not address another scalability key factor, the signaling load associated with establishing and maintaining reservations. Such load can be reduced if bandwidth is over-reserved. Over-reservation allows accommodating reservations without exchanging signaling messages, but may result in additional blocking. In this paper, we carry out a systematic investigation of the impact of over-reservation in different aggregation approaches, evaluating such impact in terms of the achieved signaling reduction, and blocking.

支持可伸缩的as间信令:一种减少负载的方法
为了获得更好的可扩展性,域间信令协议依赖于聚合来减少路由器需要维护的状态信息的数量。尽管如此,它们没有解决另一个可伸缩性关键因素,即与建立和维护保留相关的信令负载。如果带宽过度预留,则可以减少这种负载。超额预订允许在不交换信令消息的情况下容纳预订,但可能导致额外的阻塞。在本文中,我们对不同聚合方法中过度保留的影响进行了系统的研究,从实现的信号减少和阻塞方面评估了这种影响。
