Embodiment Construction

[0038] see figure 1 , is a schematic structural diagram of a communication system provided in the present application. The communication system may be an Ethernet system, and may specifically include a controller and an Ethernet device connected to the controller. An Ethernet device refers to a device used to implement functions defined by the Ethernet protocol. The Ethernet device at least includes an ingress device, a switching device and an egress device. Wherein, the ingress device and the egress device are edge devices. The ingress device is connected to the end device that generates the Ethernet traffic, and the egress device is connected to the end device that receives the Ethernet traffic. The switching device is located between the ingress device and the egress device, and is used to send the Ethernet traffic sent by the ingress device to the egress device. The present application does not limit the number of switching devices between the ingress device and the egr...

Abstract

The invention provides a communication control method, Ethernet equipment and a controller. The method comprises the following steps that: the Ethernet equipment receives a first bit block in a firsttime slot by using a first port; and the Ethernet equipment sends the first bit block in a second time slot by using a second port according to a first correspondence relationship, the first correspondence relationship comprising a mapping from a combination of an ingress port and a reception time slot to a combination of an egress port and a transmission time slot. In the present application, after receiving the bit block, according to a corresponding relationship from the combination of the ingress port and the receiving time slot to a combination of an output port and a sending time slot, the Ethernet equipment can determine the output port and the transmission time slot of the bit block, the bit block is transmitted in the transmission time slot by using the determined output port, andthe whole transmission process of the bit block is completed on the PHY chip without looking up a table through an MAC layer, so that the transmission rate is high, and the time delay is low.

Description

technical field [0001] The present application relates to the field of mobile communication, in particular to a communication control method, an Ethernet device and a controller. Background technique [0002] Time Sensitive Network (TSN) is a new Ethernet (Ethernet) standard. TSN is mainly used in various scenarios that need to support low-latency and time-synchronized data transmission. For example, TSN can be applied to industrial fields that require real-time monitoring or real-time feedback, as well as audio and video transmission fields. [0003] TSN usually adopts a data forwarding method based on a Media Access Control (MAC) address, that is, Layer 2 transmission. The specific data transmission process is: after the Ethernet device (such as a switch) receives the frame, it searches the MAC address table for the output port corresponding to the destination address of the frame. [0004] Since the MAC address-based transmission mode is adopted, a corresponding MAC ch...
