Data forwarding method and related device

Abstract

The embodiment of the invention provides a data forwarding method and a related device. The method comprises the following steps: a second device receives a first message sent by a first device, wherein the first message is sent by the first device within a time period T; the second equipment determines the latest time t1 when the message in the period of the first message arrives at an outlet, and takes the period next to the period with the earliest starting time in the period of the time t1 as the sending period of the first message; the starting time of the sending period takes T / M as an interval, and M is a positive integer greater than or equal to 2; and the second equipment forwards the first message to the next hop of the second equipment in the sending period of the first message. According to the method and the device provided by the invention, the time delay in the data forwarding process is reduced by reducing the interval of the starting moment of the sending period and improving the selection method of the sending period in the message forwarding process.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a data forwarding method and a related device. Background technique [0002] The communication network provides deterministic service guarantee for the services carried in the network domain, which can be called deterministic network (Deterministic Networking, DN). The core of deterministic service guarantee is to ensure end-to-end deterministic bandwidth, delay and jitter . Among them, the deterministic delay means that the delay and jitter <delay, jitter> of message transmission are lower than the upper bound on the premise that the message complies with the requirement of burstiness. [0003] The two adjacent routers in the deterministic network are respectively called the first router and the second router. The first router sends messages to the second router at a period of time T, and the messages sent at each time T can be called da...

Problems solved by technology

[0003] The two adjacent routers in the deterministic network are respectively called the first router and the second router. The first router sends messages to the second router at a period of time T, and the messages sent at each time T can be called data blocks. The method for the above-mentioned second router to perform message forwarding may be: the above-mentioned second router determines that the time when the above-mentioned data block is received and reaches the exit is completed as t 1 , then t 1 The next cycle of the cycle is used as the cycle for sending the above data block; in practical applications, the delay of the above message forwarding method is relatively large
