packet switched network definition

In fact, it has been a long time to explore the problem of network card packet capture. I found some basic things in the last few days. I will just repeat them here. Packet Capture first needs to know that the data transmitted through the NIC is actually through the underlying link layer (MAC). in Linux, the data traffic we obtain from the NIC is actually directl

Contact a period of time of the online game package design, with some preliminary ideas, want to borrow this article summed up, but also make a record, in order to facilitate the later update their own ideas.Network Game Technology research and development, divided into three main aspects: Server design, client design, database design. The intermediary between the server and the client to implement the game logic is the game data packet, and the serve

I recently developed an android network packet capture tool. I have searched the internet for a long time. No clue found So we need to work hard on the Linux layer. Therefore, tcpdump in Linux is used to implement the packet capture function. To define tcpdump in a simple way, dump the traffic on a network is a

needs to consume processing time (relative to the previous two methods), the general switch chip can automatically check the network packet Ethernet frame head, but to allow the chip to check the IP frame head, the need for higher technology, but also more time-consuming. Of course, this is related to the implementation method of each vendor. 4. According toIP Multicast PartitioningV LANIP multicast is act
