This vidoe helps you learn how to use the Windows 8 multicast LAN discovery effectively to connect people together for multiplayer games and collaboration apps.
"Internet Protocol (IP) multicast is a one-to-many and many-to-one delivery mechanism that is useful for efficiently distributing data to interested listening hosts at arbitrary locations on a home or work network, or on the Internet."
This video snack complements the BUILD technical session PLAT-580T: Building Windows Runtime Sockets Apps (second embed below).
"Today's networks have grown more complicated as a result of multihoming, web proxies, security issues, internationalization and other issues. Because dealing with these complexities is hard, it is either ignored or significant resources are spent attempting to do so. In this session, we will demonstrate how the Windows Runtime sockets API simplifies what an app must do to use TCP or UDP. We also will present exciting new functionality, such as proximity discovery and using WebSockets for HTTP proxy traversal, as well as how to handle complex security and cost issues," Microsoft said.
