larger than 1500 bytes. The transmission layer of the sender node divides the data into smaller data slices, and arranges a serial number for each data segment so that the data can reach the transmission layer of the receiver node, the process can be reorganized in the correct order, which is called sorting. It uses the maximum transmission unit value that sends a group to the network interface on the link. All parts of the original group are marked,

UDP Packet Size Problem Post from: http://blog.csdn.net/buptzwp/archive/2009/12/22/5055487.aspx During UDP programming, the most common question is how many bytes are sent at a time? Of course, there is no unique answer. The answer is different from the requirements of different systems. Here we only analyze the situation of sending chat messages like ICQ, in other cases, you may be able to get some help:First, we know that TCP/IP is generally considered as a layer-4 protocol system, includin

Problem: PPTP is used to build a VPN Server on the Linux platform. After dial-in, the Intranet FTP is accessed. downloading files is extremely slow. When using PPTP as a gateway to access the Internet, most websites except Baidu are extremely slow to access, almost inaccessible. Solution: Add-I forward-P TCP -- SYN to the * filter table of iptables of the Linux service where PPTP is located.-I ppp +-J tcpmss -- Set-MSS 1356/sbin/iptables-I forward-p tcp -- syn-I PPP +-J tcpmss -- Set-MSS 1356 Ca
