Multicast routing in datagram internetworks and extended LANs
TLDR
In this paper, the authors specify extensions to two common internetwork routing algorithms (distancevector routing and link-state routing) to support low-delay datagram multicasting beyond a single LAN, and discuss how the use of multicast scope control and hierarchical multicast routing allows the multicast service to scale up to large internetworks.Abstract:
Multicasting, the transmission of a packet to a group of hosts, is an important service for improving the efficiency and robustness of distributed systems and applications. Although multicast capability is available and widely used in local area networks, when those LANs are interconnected by store-and-forward routers, the multicast service is usually not offered across the resulting internetwork. To address this limitation, we specify extensions to two common internetwork routing algorithms—distance-vector routing and link-state routing—to support low-delay datagram multicasting beyond a single LAN. We also describe modifications to the single-spanning-tree routing algorithm commonly used by link-layer bridges, to reduce the costs of multicasting in large extended LANs. Finally, we discuss how the use of multicast scope control and hierarchical multicast routing allows the multicast service to scale up to large internetworks.read more

TL;DR: In this article, a server divides digital contents held therein into a plurality of packets, and transmits packets of a minimum unit for constructing the digital contents to the second network, where the clients include means for holding the contents therein by use of the packets of the minimum unit received from the server and packets received from other clients constructing the second networks.

Ppssm: push/pull smooth video streaming multicast protocol design and implementation for an overlay network
TL;DR: A novel ALM protocol based Push/Pull Smooth video Streaming Multicast (PPSSM) protocol is proposed, to increase the throughput and reduce the packet loss rate and the performance of the proposed PPSSM protocol shows improvement in respect of throughput, packet loss, and average decoding time.

TL;DR: The basis of this book is the material contained in the first six chapters of the earlier work, The Design and Analysis of Computer Algorithms, and has added material on algorithms for external storage and memory management.
Internet Protocol
TL;DR: Along with TCP, IP represents the heart of the Internet protocols and has two primary responsibilities: providing connectionless, best-effort delivery of datagrams through an internetwork; and providing fragmentation and reassembly of data links to support data links with different maximum transmission unit (MTU) sizes.
