Industry Standard Protocols

This paper shows one how to connect your Sametime infrastructure to another Sametime community or SIP-enabled community using the Session Initiation Protocol (SIP) for easy and secure exchange of instant messages. The Session Initiation Protocol (SIP) is a standard protocol defined by the Internet Engineering Task Force (IETF). SIP is an application-layer signaling protocol that handles interactive, multimedia sessions, including presence and instant messaging. tech news

This paper contains a detailed description of the congestion control algorithm of TRAM, a tree-based reliable multicast protocol. This algorithm takes advantage of regular acknowledgements from the receivers that propagate back to the sender via the repair tree. This scalable feedback mechanism is used to collect receiver credits. Complementing the windowing mechanism, packet transmission is smoothed by using a data rate commensurate with the window size. tech news

This document discusses the various threats against routing protocols, including peering disruption and falsifying of routing information, followed by a description of the methods and techniques used to attack a routing system tech news

A detailed description of the operation of hierarchical and recursive BGP/MPLS VPNs as described in RFC 2547bis. tech news

A single VPN protocol cannot fulfill every customer requirement, as there will always be trade-offs between functionality, interpretability and security. This paper explains the VPN solution therefore has to come from the combined protocol "L2TP with IPSec". This hybrid protocol will offer a robust, secure mechanism for creating both Client-to-LAN and LAN-to-LAN VPNs that are as easy to set up and use as PPTP. tech news
