Embodiment Construction

[0064] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0065] refer to figure 1 As shown, the forwarding architecture of the traditional packet forwarding device includes the following units: an ingress unit, a message forwarding unit, and an egress unit.

[0066] Specifically, the ingress unit receives packets through multiple ingress Media Access Control (MAC) ports, and then sequentially sends the received packets to the packet forwarding unit. The message forwarding unit queries the message forwarding table for each message, determines the corresponding forwarding information, and sends the message to the egress unit. The egress unit distributes the corresponding message to the corresponding egress MAC port according to the forwarding information corresponding to each message, and sends it to the next-hop device through the egress MAC port.

[0067] It can be seen from the above that traditional packet forwardin...

Abstract

The application discloses a method and a device for processing messages, in order to solve the problem that ultra-low-time-delay forwarding requirement can not be met due to large forwarding time delay of time-delay-sensitive business. The method comprises the steps of: acquiring a first slicing data frame included in a first data frame from an MAC (Media Access Control) layer by first network equipment, caching the first slicing data frame to a first queue; acquiring a second slicing data frame included in a second data frame from the MAC layer by the first network equipment, caching the second slicing data frame to a second queue; transmitting the first slicing data frame to a forwarding processing module by the first network equipment, and acquiring first forwarding information throughthe forwarding processing module; and transmitting the second slicing data frame to the forwarding processing module by the first network equipment after the first slicing data frame is transmitted tothe forwarding processing module, and acquiring second forwarding information through the forwarding processing module. Through adoption of the method provided by the application, forwarding time delay of the time-delay-sensitive business in network equipment can be reduced and the time-delay-sensitive business can not be affected by non-time-delay-sensitive business.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message processing method and device. Background technique [0002] With the emergence of new 5G delay-sensitive services such as driverless driving, telemedicine, virtual reality, tactile Internet, and ultra-high-definition video, the end-to-end delay of the operator network is required to be no more than 1ms, and it is decomposed into a single group. The forwarding device needs to meet the requirement of microsecond (us)-level ultra-low latency, which is difficult to meet with the traditional packet transmission network, and it is necessary to reduce the forwarding time of data packets in a single packet forwarding device. [0003] Traditional packet forwarding devices generally support two forwarding modes: store and forward (Store and Forward) and cut-through forwarding (Cut-Through). Among them, the Store and Forward method requires sending data to ...
