whitepaper Design and Implementation of the Network Server Based on SIP Communication Protocol2007-11-25 World Academy of Science, Engineering and Technology
  SIP is a kind of application-layer control signaling protocol for creating, modifying and finishing the conversation with one or more participants. It has several advantages such as simple, good expansibility and scalability, and so on. Based on the SIP, in this paper a design and implementation scheme of SIP server system is proposed, and the scheme can realize the functions of IP phone such as calling, billing and so on, and finally based on the standards and interfaces of JainSip API which was provided by SUN company the design scheme is realized.

whitepaper IBM System Storage N Series: An iSCSI Performance Overview2007-04-12 IBM
  The iSCSI protocol has enabled information technology organizations to lower the cost of their Storage Area Network (SAN) deployments. Cost is of little concern if the solution does not perform to expectations. This paper examines some of the issues and options that are available with the IBM N series storage product range with an aim to improve performance in an iSCSI environment.

whitepaper Towards Stateless Core: Improving SIP Proxy Scalability2007-01-10 Georgia Institute of Technology
  The Third Generation Partnership Project (3GPP) specified the IP Multimedia Subsystem (IMS) standard. This standard uses the Session Initiation Protocol (SIP) to setup and teardown multimedia sessions through a potentially large chain of proxies. The IMS standard allows some core elements to be deployed as transaction stateful or stateless proxies. Moreover, SIP standard allows proxies decide when to store transaction information on a per request basis. This paper examines the implementation of these core IMS proxies. It proposes an algorithm that determines for each incoming request when to store transaction information. The goal of this algorithm is to increase throughput by reducing the number of transactions without compromising call setup times.

whitepaper The LDAP Standard Specification2007-01-01 Isode
  In June 2006, 10 new LDAP RFCs were published (RFCs 4510-4519) to provide a new LDAPv3 (Lightweight Directory Access Protocol version 3) specification and to replace RFC 2251 and a number of related specifications. The primary goal of this paper is to guide those with some basic knowledge of LDAP.

whitepaper The MS-CHAP Version 1 Authentication Protocol Has Been Deprecated in Windows Vista2006-12-09 01:00:17 Microsoft
  The MicroSoft Challenge Handshake Authentication Protocol version 1 (MS-CHAP v1) has been deprecated in Windows Vista. This paper discusses this change and provides methods to work around it. In Windows Vista, Microsoft has removed MS-CHAP v1 from the list of authentication protocols for dial-up connections, for broadband (PPPoE) connections, and for Virtual Private Network (VPN) connections. This change has been made because MS-CHAP version 2 (MS-CHAP v2) provides better security.   
whitepaper A Robust Integrity Reporting Protocol for Remote Attestation2006-10-31 Darmstadt University of Technology
  Trusted Computing Platforms provide the functionality of remote attestation, i.e. attesting the configuration and status of a system to a remote entity. Remote attestation hereby proves integrity and authenticity of system environments. This is crucial for policy enforcement, which in turn is needed in many usage scenarios, e.g., DRM. However, applying remote attestation solely allows masquerading attacks. These attacks are possible since the concept of remote attestation does not provide any means for establishing secured communication channels. This paper describes this kind of attacks against protocols for remote attestation and presents a protocol for preventing masquerading attacks.
