whitepaper Control Mechanism for QoS Guaranteed Multicast Service in OVPN Over IP/GMPLS Over DWDM2007-01-01 Academy Publisher
  OVPN over IP/GMPLS over DWDM technology with QoS assurances is considered as a promising approach for the next generation OVPN. This paper suggests a multicast OLSP (Optical Label Switched Path) establishment mechanism for supporting high bandwidth multicast services in OVPN over IP/GMPLS over DWDM. For the establishment of the multicast OLSP, the paper proposes a new multicast tree generation algorithm VS-MIMR that finds the minimum interference path between virtual source nodes. The paper also suggests an entire OVPN control mechanism to adapt the operation of the routing and signaling protocols of GMPLS.

whitepaper Multicast in a Campus Network: CGMP and IGMP Snooping2007-01-01 Cisco Systems
  The purpose of Cisco Group Management Protocol (CGMP) and Internet Group Management Protocol (IGMP) snooping is to restrain multicast traffic in a switched network. By default, a LAN switch floods multicast traffic within the broadcast domain and this can consume a lot of bandwidth if many multicast servers are sending streams to the segment.

whitepaper Fair Bandwidth Sharing Between Unicast and Multicast Flows in Best-Effort Networks2007-01-01 French National Institute for Research in Computer Science and Control
  This paper proposes a simple scheduler called SBQ (Service-Based Queuing) to share the bandwidth fairly between unicast and multicast flows according to a new definition of fairness referred as the inter-service fairness. The paper also describes a new active queue management mechanism called MFQ (Multicast Fair Queuing) to fairly share the allowed multicast bandwidth among competing flows in the multicast queue. The simulation results obtained for very heterogeneous sources and links characteristics suggest that, on the one hand, SBQ achieves the expected aggregated bandwidth sharing among unicast and multicast service, and on the other hand the multicast flows remain TCP-friendly.

whitepaper RMCM: Reliable Multicasts for Core-Based Multicast Trees0000-00-00 Ohio State University
  Reliable multicast is one of the important and challenging problems that must be effectively resolved before multicast applications can be fully deployed on the Internet. Most existing reliable multicast schemes focus on source-based multicast trees. They either cannot be directly deployed in core-based multicast trees or may render sub-optimal performance when directly deployed. The major difficulty lies in that an on-tree router on a core-based tree does not know, due to lack of the per-source information, how to direct a retransmission request (NAK) toward the sender or some designated replier router/host. This paper presents a design and evaluates a Reliable Multicast scheme for Core-based Multicast trees, called RMCM.

whitepaper Multicast Network Management2006-12-01 Cisco Systems
  This paper provides an overview of the instrumentation, tools, and solutions that enable the management of Cisco IP multicast deployments. The paper focuses on the areas of fault, configuration, and performance management. The methods and solutions employed to monitor and control resource-usage accounting and security for an IP multicast deployment do not differ from any other network, and are, therefore, covered other Cisco reference documents.

whitepaper An Overview of Link Local Multicast Name Resolution2006-11-29 TechGenix
  When a user on a corporate network needs to access some resource off of another computer, the user usually specifies the remote system's NetBIOS name when establishing the connection. This means that users can attach to a remote system by using its NetBIOS name and Windows will query the DNS server in order to determine the IP addresses associated with the host record matching the computer's name. In most cases, it is either impossible or impractical to add a DNS server to a home network or to an ad-hoc network. This makes name resolution impossible. Windows Vista in Longhorn Server will change this with the new technology called link local multicast name resolution.

whitepaper Bounds on the Network Coding Capacity for Wireless Random Networks2006-11-16 Texas A&M University
  Recently, it has been shown that the max flow capacity can be achieved in a multicast network using network coding. This paper proposes and analyzes a more realistic model for wireless random networks. The authors prove that the capacity of network coding for this model is concentrated around the expected value of its minimum cut. Furthermore, the authors establish upper and lower bounds for wireless nodes using Chernoff bounds. The experiments show that the theoretical predictions are well matched by simulation results.

whitepaper Multicast in 802.11 WLANs: An Experimental Study2006-10-06 Association for Computing Machinery
  While the deployment of WiFi networks continues to grow at an explosive rate, the multicast multimedia delivery service on WiFi compliant devices is still in its early stage of development. The real culprit is the IEEE 802.11 MAC protocol, and in particular, the absence of feedback mechanism when multicast is used. Recently, a leader-based mechanism has been proposed to overcome this problem. This paper measures the characteristics of the legacy multicast transmission mechanism and analyze its flaws. Then, it studies the performance of the leader-based approach and compares its performance with the standard multicast service.

whitepaper Securing IP Multicast Services in Triple-Play and Mobile Networks2006-10-01 Cisco Systems
  Cisco IP Multicast, the established bandwidth-conservation technology, not only increases the efficiency of network resources and bandwidth but also is extremely secure, from endpoints to network cores, due to an array of protocols, techniques, and topologies. This paper describes the various technologies that can be deployed in the control plane, data plane, access layer, and infrastructure and through admission control features to secure IP Multicast traffic for these highly demanding services.
