Protocols In Data Communication

The following article is mainly about wireless encryption is commonly used in wireless network encryption protocol, in the actual operation of the widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol two. The widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol. WEP protocol is also called Wired Equivalent encryption protocol, this kind of wireless communication protocol is often those who are eager to produce and sell wireless equipment in a relatively short period of time to put together the informal wireless encryption communication standards, from the current view of this wireless network encryption protocol There are quite a lot of security ...

Hadoop RPC communication is different from other systems RPC communication, the author for the use of Hadoop features, specifically designed a set of RPC framework, the framework of personal feeling is still a little complicated. So I'm going to split into client-side and Server service-side 2 modules for analysis. If you have a good understanding of RPC's entire process, you must be able to understand it very quickly for Hadoop RPC. OK, let's cut to the chase. The related code for the RPC of Hadoop is ORG.APAC ...
