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.

whitepaper COCOON: An Alternative Approach to End-Point Congestion Management0000-00-00 Alcatel-Lucent
  This paper proposes an alternate endpoint congestion management scheme, called COordinated COngestion cONtrol (COCOON). The basic idea is to identify and group connections that may traverse the same backbone link, to enable them to share congestion information, and to coordinate among them all the congestion avoidance/control activities. The size of a COCOON group can be dynamically adjusted so as to magnify the benefits of end-host congestion management. COCOON also allows a new connection to commerce with a congestion window that is large enough to catch up with other connections while not inducing congestion. Finally, COCOON takes into account non-responsive UDP connections and "Bundles" them into a virtual connection that is subject to TCP-like congestion control.

whitepaper Timed Spi-Calculus With Types for Secrecy and Authenticity0000-00-00 Alcatel-Lucent
  This paper presents a discretely timed spi-calculus. A primitive for key compromise allows to model key compromise attacks, thus going beyond the standard Dolev-Yao attacker model. A primitive for reading a global clock allows the authors to express protocols based on timestamps, which are common in practice. The authors accompany the timed spi-calculus with a type system, prove that well-typed protocols are robustly safe for secrecy and authenticity and present examples of well-typed protocols as well as an example where failure to typecheck reveals a (well-known) flaw.   
whitepaper SPACE: Secure Protocol for Address-Book Based Connection Establishment2006-11-13 Microsoft
  This paper presents SPACE an application-level protocol for secure automatic ad-hoc connection-establishment between two devices based on their address book entries. The protocol is based on the simple premise that if two people have each others contact details in their address books, they probably know and trust each other in some limited way and this can form a basis for a trust relationship between their devices, without additional user intervention. This paper shows how the protocol is resistant to specific security attacks and can accommodate for privacy concerns. Existing connection-establishment protocols for Bluetooth and IEEE 802.11 have known security flaws, and can be compromised using well-known techniques and off-the-shelf hardware. In addition, these protocols require explicit user intervention, like entering a passkey.
