whitepaper Wireless Mobile Ad-Hoc Network Protocols and Evaluation With Model Checking2007-02-28 Harvard University
  A Mobile Ad-hoc NETwork (MANET) is a wireless network set up temporarily without a wired infrastructure (routers, switches, servers, cables, access points, etc.). The wireless nodes in a MANET may move around and each one of them may need to forward packets for other components in the network. Because they can be deployed quickly, MANETs could be used for disaster rescue, battle field communication, sensor networks, etc. this paper focuses on investigating the specific properties that a wireless routing protocol needs to satisfy, evaluating existing wireless routing protocols with model checking, and designing better protocols.

whitepaper Cisco IOS Firewall Authentication Proxy for FTP and Telnet Sessions Buffer Overflow0000-00-00 Cisco Systems
  Cisco Systems has released Cisco Security Advisory: Cisco IOS Firewall Authentication Proxy for FTP and Telnet Sessions Buffer Overflow. This paper describes the Firewall Authentication Proxy (Auth-Proxy) feature and discusses the workarounds and mitigations identified in the advisory. The firewall authentication proxy feature allows network administrators to apply specific security policies on a per-user basis.

whitepaper HPTP: Relieving the Tension Between ISPs and P2P2007-01-27 Microsoft
  Measurement-based studies indicate that there is a severe tension between P2P applications and ISPs. This paper proposes a novel HTTP-based Peer-To-Peer (HPTP) framework to relieve this tension. The key idea is to exploit the widely deployed web cache proxies of ISPs to trick them to cache P2P traffic. This is achieved via a process the authors refer to as "HTTPifying": the authors segment large P2P files or streams into smaller chunks, encapsulate and transport them using the HTTP protocol so that they are cacheable and outline the design of several key tools of the proposed HPTP framework - HTTPifying, cache detection and usability test tools, and describe a Cache-Aware Tree Construction (CATC) protocol for delivering P2P streaming traffic as an example to showcase the HPTP framework.

whitepaper A Quick Look at IPv6 and IPSec Protocols2007-01-01 Hewlett-Packard (HP)
  Hewlett-Packard uses a variety of security standards and recommended protocols to ensure that the LaserJet printers and MFPs are capable of serving as active components of the organization's security plan. This paper explains about two such protocols: IPv6 and IPSec. IPv6 is a network layer Internet Protocol (IP) standard used by electronic devices to exchange data across a packet-switched internetwork. IPSec is short for Internet Protocol Security, a set of protocols designed to support secure exchange of packets at the network IP layer.

whitepaper Cisco IPv6 Solutions2007-01-01 Cisco Systems
  The continuous growth of the global Internet requires that its overall architecture evolve to accommodate the new technologies that support the growing numbers of users, applications, appliances, and services. Internet Protocol version 6 (IPv6) is designed to meet these requirements and enable a global environment where the addressing rules of the network are again transparent to the applications. This paper describes the Cisco position and details current and future IPv6 support across Cisco strategic product families.

whitepaper TCP-Planet: A Reliable Transport Protocol for InterPlaNetary Internet2007-01-01 Georgia Institute of Technology
  The space exploration missions are crucial for acquisition of information about the space and the universe. The entire success of a mission is directly related to the satisfaction of its communications needs. For this goal, the challenges posed by the InterPlaNetary Internet need to be addressed. Current TCP protocols have very poor performance in the InterPlaNetary Internet which is characterized by extremely high propagation delays, link errors, asymmetrical bandwidth and blackouts. The window-based congestion control, which injects a new packet into the network upon an ACK reception, is responsible for such performance degradation due to high propagation delay. Slow start algorithms of the existing TCP protocols further contribute to the performance degradation by wasting long time periods to reach the actual data rate.

whitepaper Performance of Different Proxy Concepts in UMTS Networks2007-01-01 University of Stuttgart
  It is well known that the large round trip time and the highly variable delay in a cellular network may degrade the performance of TCP. Many concepts have been proposed to improve this situation, including Performance Enhancing Proxies (PEPs). One important class of PEPs are split connection proxies, which terminate a connection from a server in the Internet in a host close to the Radio Access Network (RAN) and establish a second connection towards the mobile User Equipment (UE). This connection splitting can be done either purely on the transport layer (TCP proxy) or on the application layer (HTTP proxy in the case of web traffic).

whitepaper Network Design for OSPF Routing2007-01-01 University of Campinas
  Internet Protocol (IP) traffic follows rules established by routing protocols, such as Open Shortest Path First (OSPF). Each router computes shortest paths using weights assigned by the network operator, and creates destination tables used to direct each IP packet to the next router on the path to its final destination. Furthermore, the routing protocol is used to establish procedures to be taken in case of a failure in the network. In this extended abstract, the paper describes a new genetic algorithm for designing a network with minimal total link capacity necessary to route demand without overload in case of any single edge or node failure.

whitepaper Evolution of the Spanning Tree Protocol2007-01-01 Force10 Networks
  The Spanning Tree Protocol, that is the basis for the IEEE standard 802.1D was designed to provide "plug-and-play" operation for large Layer 2 networks based on half duplex shared Ethernet, which was the prevalent LAN technology throughout the late 1980s and early 1990s. As Ethernet evolved to become a switched full duplex technology, it soon became evident that 802.1D needed to be upgraded in order to keep pace with the new design models and switch features (e.g., VLANs) that emerged to allow optimization of switched networks.
