Wireless Mobile Ad-Hoc Network Protocols and Evaluation With Model Checking | 2007-02-28 | 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.

TechNet Webcast: Why Deploy Internet Protocol Version 6 (IPv6)? (Level 200) | 0000-00-00 | Microsoft |
| This webcast explains how IPv6 is designed to solve many issues within the current version of IP, Internet Protocol version 4 (IPv4). The webcast discusses the limitations in IPv4, like address depletion, security, auto-configuration, and extensibility, and explore how IPv6 addresses these issues, while introducing a new addressing structure.

Cisco IOS Firewall Authentication Proxy for FTP and Telnet Sessions Buffer Overflow | 0000-00-00 | 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.

University Uses Existing Windows Investments to Tighten Network Security and Management | 0000-00-00 | Microsoft |
| The Universidade de Vila Velha (UVV) in Brazil is host to 14,000 students. Like most universities, UVV provides computer resources for its students, faculty, and administrative staff. To ensure better security, UVV kept its faculty and staff network separate from the student network. But managing separate networks was difficult and became increasingly expensive as the university continued to grow. In 2005, UVV implemented a highly secure network using a Server and Domain Isolation solution based on Internet Protocol security (IPsec). The solution allowed the school's two networks to coexist on a single physical network.

HPTP: Relieving the Tension Between ISPs and P2P | 2007-01-27 | 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.

A Quick Look at IPv6 and IPSec Protocols | 2007-01-01 | 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.

TCP-Planet: A Reliable Transport Protocol for InterPlaNetary Internet | 2007-01-01 | 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.

Performance of Different Proxy Concepts in UMTS Networks | 2007-01-01 | 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).

Network Design for OSPF Routing | 2007-01-01 | 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.
