“…The idea of aggregation was firstly studied in [8], further exploited by A. Fei et al for IP multicast routing with/without MPLS in [9][10][11], and it has been revisited in the specific context of MPLS VPNs in several works [7,12] where different aspects are addressed together with aggregation, including P2MP tree signaling and frame encapsulation mechanisms on the shared tree. In [10] the authors address many implementation aspects of group management and introduce a centralized management entity called tree manager, which is in charge of assigning groups to existing trees or create new ones.…”

“…In [12] authors use the same aggregation algorithm and applies the same to the particular case of VPN MPLS implementation based on label stacking. In [11], the authors extend their work from [9,10] to support QoS by including measurement-based admission control to aggregated MPLS trees featuring Diffserv. Yet the forwarding state analysis and aggregation method is similar.…”

“…Instead, entries stored at PE routers are specific for VPNs. In [9] authors introduce the concepts of reducible and non-reducible state information. By using ATs, or even by using traditional IP multicast, terminal nodes necessarily need state information related to multicast traffic of VPNs, and that is why this state information is called non- 6, 7).…”

“…The trade-off is that this approach may waste extra bandwidth to deliver multicast data to non-group-member nodes. In our earlier work [8,9], we introduced the basic concept of aggregated multicast, proposed an algorithm to assign multicast groups to delivery trees with controllable bandwidth overhead and presented some initial results to show that multicast state can be reduced through inter-group tree sharing. However, a thorough performance evaluation of aggregated multicast is needed: what level of the gain does aggregated multicast offer over conventional multicast schemes?…”

Abstract. Multicast state scalability is among the critical issues which delay the deployment of IP multicast. In our previous work, we proposed a scheme, called aggregated multicast to reduce multicast state. The key idea is that multiple groups are forced to share a single delivery tree. We presented some initial results to show that multicast state can be reduced. In this paper, we develop a more quantitative assessment of the cost/benefit trade-offs. We introduce metrics to measure multicast state and tree management overhead for multicast schemes. We then compare aggregated multicast with conventional multicast schemes, such as source specific tree scheme and shared tree scheme. Our extensive simulations show that aggregated multicast can achieve significant routing state and tree management overhead reduction while containing the expense of extra resources (bandwidth waste and tunnelling overhead, etc.). We conclude that aggregated multicast is a very cost-effective and promising direction for scalable transit domain multicast provisioning.

Abstract. As the number of simultaneously active groups increases, IP multicast suffers from scalability problem. In backhone networks, the state scalability problern is even more serious. In this paper, we propose a novel scheme, called AMBTS, which uses the concept of aggregated multicast, and employs tree splitting before aggregating. We design an algorithm to divide the leaf nodes of backhone into different sub-groups, and then splitting the native multicast spanning tree. We propose a scheme to assign a set of aggregated multicast trees to deliver packets for a group. Analyses and simulations show that AMBTS can greatly improve state scalability: the number of aggregated trees is bounded in a small fixed number, and the multicast routing entries in transit nodes decreased dramatically.
