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

UDP packet LengthThe theoretical length of UDP packetsWhat is the theoretical length of UDP packets and what should be the appropriate UDP packets? As can be seen from the packet header of the UDP packet in the 11th chapter of TCP-IP, the maximum packet length of UDP is 2^16-1 bytes. Since the UDP header accounts for 8 bytes, and the IP packet is encapsulated at the IP layer, it takes up 20 bytes, so this is the maximum theoretical length of the UDP packet is 2^16-1-8-20=65507.However, this is o
