【摘要】 介绍了一种引入标记聚集的新机制来实现多协议标记交换(MPLS)中的IP组播,并分析了该机制。与原有无标记聚集机制相比,该机制延时低,所需标记数少。所以可采用该机制来解决MPLS中组播的可扩展性问题。更多还原

【Abstract】 This paper introduces and analyses a new mechanism which adopts label aggregation to realize IP multicast in MPLS. Compared with the previous mechanism without label aggregation,it has less delay and reduces label consumption.So,the scalability problem of MPLS IP multicast can be solved through this mechanism.更多还原
