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

A system for constructing configurable high-level protocols
TL;DR: A network subsystem that supports modular, fine-grained construction of high-level protocols such as atomic multicast and group RPC is described, based on extending the standard hierarchical model of the x-kernel with composite protocols in which micro-protocol objects are composed within a standard runtime framework.

I/O Requirements of Scientific Applications: An Evolutionary View E. Smirni.
TL;DR: The results show that both small and large request sizes are common, that at present, application developers must manually aggregate small requests to obtain high disk transfer rates, and that appropriate matching of the application access pattern and the file system access mode can significantly increase application I/O performance.

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.
