There are a lot of articles about implementing WCF communications in SL, so I'm focusing on my practice, which is probably understandable.
First, a brief introduction to the WCF
Full name: Windows communication Foundation starting from the Dotnet Framework 3.0, WCF traffic provides multiple methods for communicating with HTTP, TCP, and IPC channels. The channel provided by WCF uses DCOM for communication. WCF is suitable for sending messages quickly
Installation and server configuration of the six management tools for Microsoft Office Communications Server 2007 R2 Deployment
This chapter describes
1. Installation Management Tools
2. User Configuration, enabling OCS services for users
3. Set up OCS to allow clients to login in TCP mode
4. Set up DNS
Get to the point.

Now is the last step, how to actively send data to the front end? This will use the new features of HTML5: Server send event (to use newer non-IE browsers, specifically view here). See the JS code directly

The Agent/master HTTP interface is rest-like and varies from strictly RESTful design in several ways. The endpoints used by the agent is detailed in the HTTP API reference. Note that all HTTP endpoints is preceded by the environment being used. Note also that access to each individual endpoint are controlled byauth.conf on the master.DiagramThis flow diagram illustrates the pattern of agent-side checks and HTTPS requests to the puppet master during a single Pup Pet run.See below the image for a

Introduction: Learn how to configure the Kerberized Open Secure Shell (OpenSSH) on a aix®version 5.3 computer that uses microsoft®active Directory server as the Key Distribution Center (KDC). OpenSSH encrypts communications (including passwords) to prevent eavesdropping, to take over communication connections, or to peek at data. If you work with the AIX Version 5.3 system in a mixed multi-vendor solution environment, you'll find this article valuable
