Android Network programming series one TCP/IP protocol family

When we learn and use the Android network programming, we touch only the upper layer protocols and interfaces such as Apache HttpClient or Android's own httpurlconnection and so on. We also need to learn more about the underlying implementations of these interfaces, which requires that we understand the network communication layer and that the network communicati

TCP/IP network explaining: OSI Seven layer model (lesson two)

model of today's Internet use is the TCP/IP model, and the latter do not use layers 5th and 6th of the OSI, so we ignore them.Well, I think you should understand. Of course, the 7th level we need to consider. In fact, it was for this 7th tier application that we took the trouble to build this model. Yes, the 7th floor is Mister, you have to wait, is so capricious →_→Layer 7th or Application layer:

After the installation of network hardware and network protocol, we generally have to do the TCP/IP protocol testing, then how to test is a more comprehensive test? We believe that comprehensive testing should include two aspects of local area network and Internet, so it sho

Overview of the TCP/IP protocol for testing your network

After the network hardware and network protocols are installed, we usually need to test the TCP/IP protocol. How can we perform a comprehensive test? We believe that the comprehensive test should include two aspects: Lan and Internet. Therefore, we should test the LAN and Internet, the following are the steps to test t

As long as you do not accept, the number of sockets in the kernel queue will not be reduced.4 Close: When we close the connection, we use close to actually just subtract the reference count of the file descriptor by 1, and one fork causes the open see Descriptor reference count in the parent process to be added by 1. So in this case we should do a close to the file descriptor in the parent-child process. If you want to terminate the connection directly, you can use the shu
