S. Yan, B. Lin
2009 IET Computers & Digital Techniques  
We formulate the joint multicast routing and network design problem using a rip-up and reroute procedure, where each multicast routing step is formulated as a minimum directed spanning tree problem, and  ...  Our new formulation adopts a rip-up and reroute concept that provides us with a heuristic iterative mechanism to identify increasingly improving solutions.  ...  Thus our multicast benchmarks cover a large range of applications with mixed unicast/multicast flows and varying hop count and data rate distributions.  ...

An overview of quality of service routing for next-generation high-speed networks: problems and solutions

Shigang Chen, K. Nahrstedt
1998 IEEE Network  
The delay constraint of a multicast connection requires that the longest end-to-end delay from the sender to any receiver in the tree must not exceed an upper bound.  ...  Many unicast/multicast QoS routing algorithms have been published recently, and they work with a variety of QoS requirements and resource constraints.  ...  Algorithms were derived from the framework to route connections with a variety of QoS constraints on bandwidth, delay, delay jitter, cost, and their combinations.  ...

2009 arXiv   pre-print
As we know, the member-only algorithm in provides the best links stress and wavelength usage for the construction of multicast light-trees in WDM networks with sparse splitting.  ...  Simulations show the proposed algorithm is able to greatly reduce the diameter and average delay of the multicast tree (up to 51% and 50% respectively), while keep the same or get a slightly better link  ...  The members of a multicast session and the MC nodes in the networks are assumed to be uniformly distributed.  ...

Scaling IP multicast on datacenter topologies

Xiaozhou Li, Michael J. Freedman
2013 Proceedings of the ninth ACM conference on Emerging networking experiments and technologies - CoNEXT '13  
Unfortunately, traditional protocols for managing IP multicast, designed for arbitrary network topologies, do not scale with aggregate hardware resources in the number of supported multicast groups.  ...  For example, experiments show that a datacenter with 27,648 servers and commodity switches with 1000-entry multicast tables can support up to 100,000 multicast groups, allowing each server to subscribe  ...  However, with fast failover to local rerouting, we can allow some reasonable delay until multicast tree reconstruction, and thus lessen the computational burden on network controllers.  ...

Kwan-Wu Chin, Mohan Kumar
2002 Computer Communications  
With MCoRe, source migration is transparent to the multicast group members and does not entail reconstruction of existing multicast tree.  ...  In this paper we propose multicast connection rerouting (MCoRe), a novel scheme for ef®cient multicasting in mobile asynchronous transfer mode (ATM) networks.  ...  There are two main disadvantages with path extension: increased end-to-end delay and likely formation of loops.
