“…Some schemes in applying multicast to MPLS network environment have been proposed. In MMT (Multicast MPLS Tree) [2], reducing the information quantity to be memorized in routers and ensuring scalability by limiting the presence of multicast routing states to branching node routers. In [3], each domain contains NIMS (Network Information Management System) for each group, charged to collect join and leave messages from all group members in that domain.…”

Merging MPLS andMulticast technologies is a valuable and hard issue. In this paper, presenting and analyzing a mechanism of AERM (Active Edge Routers Multicast) in MPLS environment. Setting up active ideal multicast tree by a mechanism of APM (Active and passive management), which avoids network bottleneck happening and reduces the forwarding states of the middle LSRs (Label switching routers) in Multicast Tree. It can improve the scalability of MPLS.

“…As for MPLS multicast, Edge Router Multicasting [14] and the scheme proposed by Boudani et al [15] are techniques to build point-to-multipoint LSPs by utilizing only unicast LSPs in the network. In these solutions, the amount of links a multicast trees contain is not optimal.…”

Large enterprises usually require Virtual Private Network (VPN) services provisioned by the network operator. Also, there is an emerging need for supporting multicast communications, i.e. one host communicate with other hosts located in multiple remote sites. While MPLSbased IP VPNs are proven to be scalable, current approaches for extending it with multicast features involve potential state explosion, some bandwidth inefficiencies in the operator network or complex management tasks to find a good balance between forwarding state and bandwidth usage. These properties are direct consequences of the current MPLS and network-layer multicast forwarding approaches, as state should be maintained in the forwarding plane for each tree in each intermediate node.In this paper, we build on a stateless Bloom-filter-based forwarding plane installed in the service provider's network. By moving the state into the packet headers from the nodes, new trade-offs appear due to the probabilistic nature of Bloom filters. We highlight autonomic scenarios, such as selfconfiguration of addresses, resource management in the network, simple autonomic provisioning of dynamic multicast trees and self-optimization of forwarding performance.

“…In [5,6], authors propose to minimize the number of labels required by multicast sessions by using unicast LSPs comprising the corresponding multicast trees. However, multicast sessions typically require high bandwidths, and their This work has been supported by the Serbian Ministry of Education, Science, and Technology, Telekom Srbija, and Informatika.…”

Due to a continuous rise in Internet traffic and the appearance of new services, the use of IP protocol routing can lead to the congestion of the network resources. Because of this, the modern networks use the MPLS technology to enable support to a wide spectrum of services and make Internet traffic management more efficient. Multicast traffic is becoming more popular on the Internet, so the MPLS must efficiently support multicast traffic as well. This paper proposes the hardware implementation of the control protocol which should enable the exchange and updating of labels used for multicast traffic (mLDP). Advantage of the presented hardware implementation is that it could support higher scalability and more dynamic traffic compared to the standard, software solutions. We will examine performance of the implementation in terms of the resources that it consumes, as well as the possibilities for its further improvement.
