Example Embodiment
[0038] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0039] Such as figure 1 As shown, the sender initializes the congestion window field carried in the data packet, such as the 16-bit window field in the TCP data packet header, the initial value can be 0xffff, and then allocates the congestion window value according to the switch buffer pool size, and then The packet is sent.
[0040] The switch periodically counts and maintains the total number N of data flows passing through each port, with various statistics and calculation methods. For example, the handshake signal during connection establishment and disconnection can be used for statistics and updates. When receiving a connection establishment request such as TCP's SYN, N increases by 1; when receiving a co...
