Through the Linux network programming-the original socket programming, we know that we can get the link layer packets through the raw sockets and recvfrom (), what is the link Layer Packet we receive ? Link Layer envelope formatMAC head (wired LAN)Note : CRC, PAD can be ignored when group packageOne of the scenarios of a link-layer packet:unsigned char msg[1024] = {//--------------group mac--------------0xb8, 0x88, 0xe3, 0xe1, 0x10, 0xe6,//Dst_mac:b

Socket (socket), similar to file descriptor, three kinds1, streaming Sockets (SOCK_STREAM): can provide a reliable, connection-oriented traffic flow, it uses the TCP protocol. TCP guarantees the correctness and sequencing of data transmission.2. Datagram Sockets (SOCK_DGRAM): Defines a non-connected service that transmits data through separate messages, is unordered, and is not guaranteed to be reliable and error-free, using Datagram Protocol (UDP).3, the original socket (SOCK_RAW): Directly bas

I've been thinking about life again. T_t,nd Array opened small, has been WA, adjusted for one hours only to find AH!!!!! I always thought my isap wrong t_t, but absolutely right!!!!In fact, the first question is very simple, run once the maximum flow can. The second question is to run the maximum flow of the residual network on each edge of the expansion capacity of OO, the cost of the cost of the side, and then set a super-source with a capacity of K

DescriptionGiven a forward graph, each edge has a capacity of C and an expansion fee of W. The expansion fee here refers to the cost of expanding the capacity by 1.Please:1, in the case of no expansion, the maximum flow of 1 to N;2, the maximum flow of 1 to N to increase the minimum required for the expansion of K cost.InputThe first line contains three integer n,m,k, which represents the number of points, sides, and the amount of traffic required to the graph.The next M-line contains four integ

If read:Port=socket.getservbyname (' SMTP ', ' TCP ')Port has a return value of 25. 4, from the socket to obtain information After you establish a socket connection, you can obtain its own IP address and port number by getsockname (), or you can display the IP address and port number of the remote machine by Getpeername ().For exa

assumed that the first connection request message segment issued by a has not been lost, but has been stranded for a long time at some network nodes and has been delayed until a certain time after the release of the connection to arrive at B, which is already a defunct message segment. However, after receiving this invalid connection request segment, B is mistaken for a new connection request and sends a confirmation message to a and agrees to establ

Over half a day of Unity's API, also did not find the way to handle the socket. Unity itself has sealed a network processing class network, mainly for state synchronization. It seems to be implementing an MMO-level network application that can only be written in C #. (Unity does not resemble as, there is a direct processing packet, byte level of the underlying fu
