First of all you should try: NET silver is best to use IE Menu: Tools--> Internet Options--> Security tab, Trusted sites, delete all ICBC-related sites (or delete them all), 99% of the mistakes were made by this damned place. ========================================================================= The following are reproduced: Try it on the top. Recently a lot of users can not open ICBC website and personal net Silver landing page, on this, I spent a little time research, found that may b

I recently learned about UDP programming and got a big head. I have found a lot of materials and consulted many colleagues. I think the following information is well written, so I collected it for reference.1. 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 to this question varies with the requirements of different systems.For example, if you want to analyze the situation of sending chat messages like ICQ, you

. Here is a ping result: .......... Reply from 211.97.55.129: bytes = 32 time = 1921 Ms TTL = 244 Ping statistics for 211.97.55.129: Packets: Sent = 300, received = 271, lost = 29 (9% loss ), Approximate round trip times in Milli-seconds: Minimum = 687 ms, maximum = 4233 ms, average = 1914 Ms We can see that the response latency is very long and the packet loss rate is very high. Response latency and packet loss rate. Any item can reflect the connection status. 2: Ping test maximum transmission

and does not equal to giving up;If there are still several routes after the above two steps, select the route with the highest priority;If several routes are available, repeat the first step. To simplify the process, we use {prefix, TOS, preference} to mark each route. . Route attributes The route entry provides the routing information and data (for example, output device, Next Hop) required for IP packet delivery.(For example, the maximum transmission unit

This article summarizes the good, from: http://hi.baidu.com/to_wait/blog/item/3e855931a5a51717eac4af22.html The TCP/IP protocol involves four layers: link layer, network layer, transmission layer, and application layer.The Ethernet data frame is at the link layer.IP packageAt the network layerTCP or UDP PacketsAt the transport layerData in TCP or UDP(Data) at the application layerTheirLink isData frame {IP packet {TCP or UDP packet {data }}}-------------------------------------------------------

determined by the physical characteristics of the Ethernet. This 1500 byte is called the MTU (maximum transmission unit) of the link layer ). The Internet Protocol allows IP sharding so that data packets can be divided into small fragments to pass through links with the maximum transmission unit smaller than the original size of the data packet. This fragment process occurs at the network layer. It uses the value of the maximum transmission unit that

directly released after use. The above section describes the cache hit condition of the next hop, so under what circumstances it will not be hit. This is very simple. It is nothing more than when the lookup_nh_cache routine above returns NULL, there are several situations that may lead to this, for example, deleting or updating existing route entries for some reason. This will be explained later through a p2p virtual network card mtu problem. Before

) the Server Load balancer device then initiates a connection to the server 172.29.141.100. 4) the server and the Server Load balancer device have three handshakes. We found that the MSS values at both ends were 1440 and there was no difference, and of course there was no fault as mentioned by the original author. Supplement: MSS is the maximum data segment that can be transmitted by TCP packets each time. To achieve optimal Transmission Performance, TCP usually needs to negotiate the MSS value

The first bottleneck of openvpn is that the Tun character device reads and writes frames at one link layer. The reason why the user-mode openvpn process must have the same link-MTU on both ends, it is because each time openvpn reads a complete Ethernet frame from the/dev/NET/TUN character device, there are not many, and the library interface: ssize_t read (int fd, void * Buf, size_t count); the count in is the MTU
