XMPP Instant Messaging
Whitepapers with a special relevance to XMPP solutions together with those of a more general relevance to Instant Messaging and Presence.
| M-Link & XMPP Performance Measurements over Satcom and Constrained IP Networks This paper describes and analyses measurements made operating XMPP over a slow IP link with variable delay to simulate Satcom. These results are applicable to use of XMPP with any constrained IP network. This paper compares measurements of standard XMPP and Isode's optimized server to server protocol. Comparison measurements with IRC (Internet Relay Chat) are also given. (13th July 2010) |
| M-Link Support for XMPP over Constrained Networks This paper looks at how M-Link, Isode's XMPP server is optimized for operation over constrained networks, including Satcom, HF Radio, and other Radio links. The paper starts by looking at the benefits of using XMPP over constrained networks, and the key problems faced. Then it describes the M-Link architecture and how it addresses the various problems, both for networks where IP will be used, and for HF Radio. (25th June 2010) |
SCRAM: A New Protocol for Password Authentication |
| XMPP Boundary and Cross Domain Protection This White Paper looks at approaches for checking XMPP (Internet Standard eXtensible Messaging and Presence Protocol) traffic at organizational and other operational boundaries. It looks at the requirements on various approaches, and shows how Isode’s M-Link and M-Link Edge products can be used in these approaches. (13th Oct 09) |
| Operating XMPP over Radio and Satellite Networks XMPP, the Internet Standard eXtensible Messaging and Presence Protocol is being widely adopted for Instant Messaging (IM), Group Chat and Presence services in military networks. This paper starts by looking at the military tactical requirements for IM, Group Chat and Presence. It discusses briefly why XMPP is ideal for these services, and also as a building block for situational awareness systems and in support of voice and video communication. (7th Jan 09) |
| Using Security Labels to
Control Message Flow in XMPP Services XMPP is widely used by military and government organizations with stringent security requirements, where it is critical to ensure that sensitive information is not sent to inappropriate individuals or domains. Security Labeling is the mechanism of choice for handling sensitive information in high security environments. This paper looks at the use of Security Labels in conjunction with XMPP services, and how Isode plans to enhance its M-Link product to provide Security Label based controls for user-to-user messaging and for Multi-User Chat. (08th Nov 08) |
| XMPP, M-Link and Directory Isode provides both directory and XMPP server products, and the approach for M-Link (Isode’s XMPP Server) and associated management tools is to make maximum use of directory. This paper describes how M-Link makes use of directory, and explains why this close integration of XMPP and directory is beneficial. (23rd Sept 08) |
| Isode's Presence,
Real Time Messaging and XMPP Strategy Isode plans to add an XMPP Server to its product set, in order to provide presence and real time messaging services. XMPP is the Internet Standard eXtensible Messaging and Presence Protocol, sometimes referred to as Jabber. This paper sets out why Presence and Real Time Messaging are important to Isode's customers and markets, why XMPP, and not another technology, why Isode is building a product, rather than integrating with available XMPP servers and outlines what Isode will be providing.

General
| SNMP and Isode Servers This white paper looks at the role of SNMP (Simple Network Management Protocol) in managing systems using Isode messaging and directory servers. It explains why SNMP support is provided, the sub-agent architecture used by Isode products, and approaches to deploying SNMP monitoring. (25th May 2007) |
| Operational Monitoring and
Control of Systems using Isode Servers Isode server products are deployed in a wide variety of situations, and usually there is a high service reliance placed on them. Isode’s approach to server design and management is that the products are building blocks, with maximum use of open standard protocols for interconnection. Management is almost entirely client/server. This combination of building block + client/server means that the approach to operational management needs to be considered as part of the overall system design. This paper explains the approach Isode has taken and the options provided, that can be used to build an operational system. (1st March 2006) |
