acknowledgement, error detection and error recovery servicesC. UDP protocol: Compare unreliable10. Client and serverA. The server and client share the burden of computingA. Customer: Computer requesting service from another computerB. Server: The computer that handles client requests11. Socket (socket): is the endpoint of Internet communication and the client and server connect and communicate through sockets12.Java support for

UDP connection function into the socket class, However, Sun has added the Datagramsocket class to the later JDK, so the construction method is useless, so sun sets it to the deprecated tag, which means that this construction method can be removed in later JDK versions. For these reasons, try not to use this construction method to establish a UDP connection when writing a network program in Java.(4) public

What are the open source projects that are suitable for students to participate in C + +, network programming? The TINYHTTPD is an ultra-lightweight HTTP server, developed in C language with only 502 lines (including comments), with a simple client that can read the code to understand the nature of an Http

the TCP transmission efficiency is not as high as UDP.2,UDPIt is simple to operate and requires less monitoring, so it is usually used for client/server applications in decentralized systems with high reliability on the LAN. For example, video conferencing system, does not require audio and video data is absolutely correct, as long as the consistency can be guaranteed, in this case, the obvious use of UDP is more reasonable. Three, Java

like a pipe, it's a channel. The channel is different from the flow where the channel is bidirectional and can be used for reading, writing, and simultaneous read and write operations.The underlying operating system's channels are generally full-duplex, so Full-duplex channel can better map the underlying operating system APIs than streaming.Channel mainly divided into two major categories: Selectablechannel: User Network Read-write FileChannel: for

1. What is HttpClient?The HTTP protocol is probably the most widely used and most important protocol on the Internet now, and more and more Java applications need to access network resources directly through the HTTP protocol. while the basic functionality of accessing the HTTP protocol has been provided in the Java NET Package of the JDK, theJDK library itself p

1) processor usage (2) memory usage (3) inbound and outbound data packets (4) the overall network load data should be extracted from the/proc/stat,/proc/meminfo,/proc/net/dev files, in fact, in Embedded linux, vlan division interfaces are generally used. The traffic of a specific interface can be seen in the/proc/net/vlan/interface name file. If you have any problems or are not clear about the data to be extracted, you can use man proc to view the onl

(AIO) NIO 2.0 introduces the concept of a new asynchronous channel and provides an implementation of asynchronous file channels and asynchronous socket channels. True asynchronous non-blocking I/O when asynchronous socket channels correspond to event-driven I/O (AIO) in UNIX network programming. He does not need too much selector to poll the registered channel for asynchronous reading and writing, thus simp

Second, in many applications do not need to ensure strict transmission reliability, such as video conferencing system, does not require audio and video data is absolutely correct, as long as the consistency can be guaranteed, in this case, obviously using UDP is more reasonable.8. 2 high-level Java
