Java TCP-based socket packet Splitting Method

Recently in the socket transmission, encountered packet loss problem, troubled for a long time, saw this article, the original address: http://suwish.com/html/java-tcp-socket-stream-packet-split.html is good, now much easier. In other words, the official "empty track" animation schedule of falcom and the broken people are displayed. I mean it is really unacceptable. Of course, we can't handle this either. W

Use iptales to implement a packet-over Firewall)

I. Overview Since the 1.1 kernel, Linux has already had the packet forwarding function. In the 2.0 kernel, we use ipfwadm to operate kernel packet forwarding rules. Later, in the 2.2 kernelYou are not familiar with ipchains to control the kernel package over the rules. Currently, the latest Linux kernel version is 2.4.1. In kernel 2.4, we no longer use ipchains,Use iptables, a new kernel package overhead m

Packet unpacking of sockets

For the TCP-based development of the communication program, there is a very important problem to be solved, that is, the package and unpacking. Let's talk about my thoughts on this question. If there is any wrong, the wrong place, begged everyone to correct. Thank you first. I. Why TCP-based communication programs require packets and unpacking. TCP is a "flow" protocol, the so-called flow, is a string of data without bounds. You can think of the river water, is connected into a piece, in the me

The bottom-level packet in Windows is sent in combat

1. IntroductionThe so-called "underlying packet" refers to the "run" at the data link layer of the packet, simply said "Ethernet frame", and our common socket can only send "run" in the transport layer of TCP, UDP and other packets, these transport layer packets have been able to meet most of the demand, However, there are times when you need to send the underlying pack

Packet and unpacking of network communication

Packet sticking during Mina socket communication

During socket communication, we often encounter packet sticking problems! Nima has a high probability of frequent data increases. Mina has considered this problem. cumulativeprotocoldecoder is answer! Cumulativeprotocoldecoder class, a cumulative protocol decoder, that is, as long as there is data sent, this class will read the data and then accumulate it into the internal iobuffer, however, the specific package (decoding the data accumulated into

Solutions to UDP packet loss and disorder

Recently, I was working on a project. Before that, I had a verification program.It was found that the client sent 1000 1024 bytes of packets consecutively, and the server experienced packet loss.The reason is that the server has not completely processed the data, and the client has sent and disabled the data.I used sleep (10) to solve this problem temporarily, but this is not a fundamental solution. If the data volume is large and the network conditio

Switch: easy to understand the iso8583 packet Protocol

We have translated the Chinese version of iso8583, so my goal is to learn about iso8583 after reading this article, so that people who have never been in touch with it can comply with the iso8583 packet specification. Now, we should turn into the subject. At the very beginning, financial systems were provided only by big companies such as IBM, such as va
