Embodiment Construction

[0051] Before describing in detail an Ethernet packet flow control method and control device provided by the present invention, please refer to figure 1 The application system of Ethernet switching control device. The figure shows two very high data rate Digital Subscriber Line (VDSL) users among the many users of this system (not shown), one is 64K user 140, and the other is For 2M users 150, the data transfer rates are 64Kbps and 2Mbps, which are very different. The two users connect to the router 110 through the connection ports P5 and P6 of the second-level switching control device 130, and then the first-level switching control device 120 to obtain information services. Since the data rate of the 64K user 140 is relatively slower than that of the 2M user 150, the buffer space of the connection port P5 of the second layer exchange control device 130 will be filled up soon, so the second layer exchange control device 130 will pass Its connection port P4 sends out a broadcast f...

Abstract

The invention relates to the method for controlling the packet flux and the control device in Ethernet. When the buffer space in the target port being insufficient, the flux control packet is transmitted through the unicast instead the flux control pack sent by the source port through the broadcast. The said unicast informs the source port, which is linked to the target port, that the target portis backed up. The packet transmitted to the said target port should be paused, but the packet transmitted to other target port can be carried out so as to raise the the efficiency transmitted throughthe network.

Description

Technical field [0001] The invention relates to an Ethernet network method and device, in particular to an Ethernet network packet flow control method and a control device thereof. Background technique [0002] Due to the development of electronic technology, computers and various information digitization equipment are becoming more and more popular, and in order to achieve the purpose of resource sharing, the network has become a necessary configuration for information exchange. In a variety of different network configurations, Ethernet has the characteristics of easy acquisition, convenient installation, and fast transmission speed, which makes Ethernet-related equipment flourish, and its transmission rate has also evolved from 10Mbps to 100Mbps or even 1Gbps. , Ethernet switch control device (EthemetSwitch hereinafter referred to as switch control device) is a necessary equipment for network information exchange. [0003] In the switching control device, in addition to providi...
