in the same sk_buff would become a single TCP segment. Still, the segments can be fragmented further at IP level.
The TCP queue is activated; Packets is sent with TCP_TRANSMIT_SKB () (called multiple times if there is more active buffers).
TCP_TRANSMIT_SKB () builds the TCP header (the allocation of the Sk_buff have left space for it). It clones the SKB in order to pass control to the network la
Muduo network library source code analysis (1) EventLoop event loop (Poller and Channel)
Starting from this blog post, we began to analyze the source code of the Muduo network library, mainly combining the "Linux multi-thread Server programming" and some learning materials on the Internet!

It was very easy yesterday after analyzing the Redis event-driven model, today I'll look at Anet's code, Anet is a small package of Redis for Client/server's network operations. The official interpretation of this file in the code is:/* anet.c--basic TCP socket stuff made a bit less boring * Socket connection based on simple basic TCPBehind the made a bit less bo
