whitepaper Multi-path Routing Protocols in Wireless Mobile Ad Hoc Networks: A Quantitative Comparison2006-09-18 Springer Science+Business Media
  Multi-path routing represents a promising routing method for wireless mobile ad hoc networks. Multi-path routing achieves load balancing and is more resilient to route failures. Recently, numerous multi-path routing protocols have been proposed for wireless mobile ad hoc networks. Performance evaluations of these protocols showed that they achieve lower routing overhead, lower end-to-end delay and alleviate congestion in comparison with single path routing protocols. However, a quantitative comparison of multi-path routing protocols has not yet been conducted. This paper presents the results of a detailed simulation study of three multi-path routing protocols (SMR, AOMDV and AODV_Multipath) obtained with the ns-2 simulator.

whitepaper Virtual Ring Routing: Network Routing Inspired by DHTs2006-09-15 Association for Computing Machinery
  This paper presents Virtual Ring Routing (VRR), a new network routing protocol that occupies a unique point in the design space. VRR is inspired by overlay routing algorithms in Distributed Hash Tables (DHTs) but it does not rely on an underlying network routing protocol. It is implemented directly on top of the link layer. VRR provides both traditional point-to-point network routing and DHT routing to the node responsible for a hash table key. VRR can be used with any link layer technology but this paper describes a design and several implementations of VRR that are tuned for wireless networks. The paper evaluates the performance of VRR using simulations and measurements from a sensor network and an 802.11a testbed.

whitepaper IPTV Industry Leaders Naturally Turn to ISMA.tv to Find the Alliance2006-09-06 Verisign
  Internet Streaming Media Alliance (ISMA or the Alliance) is a non-profit trade association dedicated to the integration and development of open standards for the IPTV (Internet Protocol Television) industry and streaming rich media content such as video, audio, and associated data utilizing mainstream Internet protocols. The company wanted obvious, simple, globally-appropriate domain name. They also needed a reliable, trustworthy partner for domain name resolution services. The Internet Streaming Media Alliance turned to the .tv Corporation, a VeriSign company, to register for the "ISMA.tv" domain name in order to establish and maintain a highly successful Web presence in the .tv domain name space.

whitepaper Is There a Security Hole in Your Windows Hosting? New VERIO White Paper2006-09-01 Verio
  VERIO's white paper, "Sharks in the AppPool," describes serious security risks associated with shared application pooling. Many hosting companies achieve server densities by sharing AppPools. But for any customer with a Website that processes credit card information directly, or has proprietary scripts, this is a significant problem.

Download this white paper to learn about the risks of shared application pooling and the rewards of VERIO Web Servers for Windows.

whitepaper IPv6 - The Road Ahead2006-08-01 Alcatel-Lucent
  IPv6 is gaining momentum worldwide, driven by the need for more IP addresses than IPv4 can provide. This is particularly true in Asia where shortage of IPv4 address is more evident and the strategic importance of IPv6 is promoted by the governments. Indeed, even the US Government is getting on board with IPv6, with the DoD mandating upgrade by 2008 and other government organs likely to do the same. The adoption of IPv6 creates an opportunity for Lucent Technologies to provide additional solutions for existing customers as well as opening the doors to new customers as well. This paper describes Lucent's 3 phase plan to meet customer demand for IPv6 support.

whitepaper AuthIP in Windows Vista2006-08-01 Microsoft
  To simplify Internet Protocol security (IPsec) deployment, Microsoft Windows Vista and Windows Server Code Name "Longhorn" (now in beta testing) support an enhanced version of the Internet Key Exchange (IKE) protocol known as Authenticated Internet Protocol (AuthIP). AuthIP provides simplified IPsec policy configuration and maintenance in many configurations and additional flexibility for IPsec peer authentication.

whitepaper Distributed Nonlinear Integer Optimization for Data-Optical Internetworking2006-08-01 Institute of Electrical and Electronics Engineers
  This paper presents a novel approach for joint optical network provisioning and Internet Protocol (IP) traffic engineering, in which the IP and optical networks collaboratively optimize a combined objective of network performance and lightpath provisioning cost. The authors develop a framework for distributed multilayer optimization. This framework is built upon the IP-over-Optical (IPO) overlay model, where each network domain has a limited view of the other. The formulation allows the two domains to communicate and coordinate their decisions through minimal information exchange.

whitepaper 4CP: Competitive and Considerate Congestion Control Protocol2006-08-01 Microsoft
  This paper presents a first practical packet-level window-based congestion controller (4CP) that implements farsighted strategy, which was introduced and shown to be optimal for sources that value large long-run average throughput and are indifferent to sporadic throughput degradations. The target loss probability is adapted very slowly so that the 4CP source verifies a given (TCP) loss-throughput formula over large timescale. The send rate is reduced to (virtually) zero in a controlled manner only during bad congestion phases, and not under full control of other (TCP) transfers, as it is the case with prior low-priority service emulators.

whitepaper A Budget-Balanced and Price-Adaptive Credit Protocol for MANETs2006-08-01 Columbia University
  A virtual credit exchange protocol for Mobile Ad-hoc NETworks (MANETs) is proposed to enforce the cooperation of packet forwarding. In this protocol, each node decides a price i.e. the number of credits) charged for forwarding a unit amount of traffic (i.e. one data packet). One node's pricing decision only depends on the prices of nodes that are going to forward packets for it. Each node updates its price adaptively and distributively. Under certain condition of the demand relationship between all nodes, this protocol converges to a unique price solution and provides sustainable and stable credit levels for all nodes.

whitepaper Email Thread Reassembly Using Similarity Matching2006-07-28 National Chiao Tung University
  Email thread reassembly is the task of linking messages by parent-child relationships. This paper presents two approaches to address this problem. One exploits previously undocumented header information from the Microsoft Exchange Protocol. The other uses string similarity metrics and a heuristic algorithm to reassemble threads in the absence of header information. The pros and cons of both methods are discussed. The similarity matching method is evaluated using the Enron email corpus and found to perform well.
