Embodiment Construction

[0065]The technical solutions in the present application will be described below in conjunction with the drawings.

[0066]First, the Ethernet System 100 according to the present application is described. Such asfigure 1 As shown, the transmission device 101, the forwarding device 102, and the receiving device 103 are included in the Ethernet system 100. The transmitting device 101, a serial connection between the forwarding device 102 and the receiving device 103. The Ethernet frame to be transmitted is issued by the transmitting device 101. After the forwarding device 102, the receiving device 103 is finally reached.

[0067]It should be noted,figure 1 Only a forwarding device is shown, that is, the forwarding device 102. It should be understood that a plurality of forwarding devices may include a plurality of forwarding devices and receiving devices 103. The Ethernet frame to be transmitted is sent by the transmitting device 101, and is forwarded via a plurality of forwarding devices, ...

Abstract

The present application provides a data processing method and device, the method is applied to a communication device including the first sublayer, by adding a physical sublayer on top of the physical coding sublayer PCS of the physical layer, and the physical sublayer is different from The Ethernet rate media-independent interface xMII is connected, and the physical sublayer realizes the interleaving of data signals from multiple different media access control client MAC clients, and then instructs the PCS to encode the xMII signal through the tx_cmd command. Finally, it is sent out through the port. This method can continue to use the encoding function of PCS to decouple interleaving and encoding, and perform interleaving based on the xMII interface. It can realize port channelization for ports with multiple rates, and at the same time ensure that when the number of service flows is too large during transmission The transmission of high-priority services avoids bandwidth waste caused by frame preemption.

Description

Technical field[0001]The present application relates to the field of communications, and more particularly to a method and apparatus for realizing port channelization in a physical layer.Background technique[0002]Port channelization technology can improve the sense of determinism of network applications, low-time delay. For example, for a fixed 100Gbps port, it can be divided into a plurality of businesses required, specifically a different sub-rate such as 5 g, 20G, 40G, and the port channelization uses a forward-passing method, Solve the surfaction table used by traditional storage forwarding mechanisms, waiting in line, further providing certainty, low delays, thereby better isolating individual services.[0003]At present, in Ethernet, port channelization techniques mainly have flexible Ethernet, Flexe. The implementation of Flexe is only based on a high-speed Ethernet port, and the port is used to intend to intend to interleave the encoded 64B / 66B code block. It can be seen tha...
