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.

Abstract

Embodiments of the present application provide a method, device, computer equipment, and storage medium for determining a forwarding path. The method includes: if the data traffic is received, obtaining the key nodes that the data traffic needs to pass through to reach the destination address and the flow marks corresponding to the key nodes; encapsulating the data packets in IPv4 format corresponding to the data traffic into data packets in IPv6 format ; Write the flow label corresponding to the key node into the flow label field of the data packet in IPv6 format; according to the correspondence between the flow label in the flow label field and the node address, write the data packet in IPv6 format Forward to the node address corresponding to each key node, and finally forward to the destination address. In the embodiment of the present application, the data flow is forwarded according to the path where the specified key node is located, which is convenient for efficient fault location and abnormal troubleshooting, and at the same time, it can implement flow analysis and reasonable prediction on the data flow.

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...
