M-Link provides a range of capabilities for operating over networks with low bandwidth, high delay and poor reliability. This includes support for HF Radio and Federated Multi-User Chat (FMUC).
For more details see the section on Support for Disadvantaged Networks on the M-Link product page.
M-Link's scalability and support for both Wide and Local Area Clustering make it the natural choice for deployments supporting large and growing user numbers and concerned about service interruptions due to server or network failure, support for Disaster Recovery and for military organizations needing a survivable deployment
You can read more about this on the M-Link Clustering page.
M-Link uses Directory to hold user, authentication and group information. M-Link use Isode’s M-Vault directory (included with M-Link) or an existing directory holding account and directory information, such as Active Directory.
To read more about this, please see the page on Directory for users, groups and authentication.
Connections to non-XMPP instant messaging services (such as AIM, ICQ, Windows Live/MSN and Yahoo Instant Messenger) via support for XEP-0114 (Jabber Component Protocol) can be enabled by use of a compatible XMPP Gateway, such as the JBuddy XMPP Gateway from Zion Software.
M-Link Edge is an Isode product based on M-Link that can be configured in a number of ways to provide an XMPP Boundary Guard service. Whilst peering decisions are the simplest way to apply boundary controls, use of an XMPP Boundary Guard enables controls to be applied and checks made separate to the XMPP server(s). M-Link Edge can be used in conjunction with a High Assurance Boundary Guard.
The page on M-Link Edge gives more details.
M-Link is a standards conformant XMPP server that will operate with any XMPP client (or multi-protocol client that includes XMPP support). Some deployment environments require specialised features, such as support for security labelling, and with these environments in mind Isode offers commercial support contracts for the Swift XMPP Client.
Isode also offers commercial licensing and commercial support contracts for the Swiften XMPP Client Library.
