Forwarding path determination method, apparatus, system, computer device, and storage medium

Abstract

Embodiments of the present application provide a forwarding path determination method, apparatus, computer device, and storage medium. The method comprises the following steps: if the data flow is received, obtaining the key node through which the data flow reaches the destination address and the flow mark corresponding to the key node; Encapsulating packets of IPv4 format corresponding to data traffic into packets of IPv6 format; Writing the flow label corresponding to the key node into the flow label field of the IPv6 format packet, According to the correspondence between the flow label andthe node address in the flow label domain, forwarding the IPv6 packets to the node address corresponding to each key node according to the order in which the flow label is written, and finally forwarding to the destination address. The embodiment of the application forwards the data traffic according to the path where the designated key node is located, which is convenient for efficient fault location and troubleshooting, and at the same time can realize traffic analysis and reasonable prediction of the data traffic.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method, device, computer equipment and storage medium for determining a forwarding path. Background technique [0002] At present, the optimal path of data packets in the network is mainly selected through hop count (hop), metric value (metric), cost value (cost) or comprehensive comparison. For example, the path forwarding strategy corresponding to RIP (Routing Information Protocol, Routing Information Protocol), IGRP (Interior Gateway Routing Protocol, Interior Gateway Routing Protocol) and other protocols is to select the best path through the number of hops, IS-IS and other protocols correspond to The path forwarding strategy is to select the best path through the measurement value. The path forwarding strategy corresponding to EIGRP (Enhanced Interior Gateway Routing Protocol, enhanced interior gateway routing Value to select the best path, there are...

AI Technical Summary

Problems solved by technology

Interior gateway protocols (such as RIP, OSPF, IS-IS, IGRP, EIGRP) select the best path by considering the number of hops or considering a single influencing factor. The algorithm for selecting the best path has shortcomings, such as the number of hops ignores bandwidth and delay. , the cost value ignores delay, bandwidth occupation and backup path, etc.

BGP protocol has a strong control ability in the calculation of the best path but lacks the ability to calculate dynamic paths. TE has strong path control capabilities and intelligent path selection capabilities but has high complexity and weak path control capabilities.
