Problems solved by technology

[0006] On the one hand, the centralized controller will have a bottleneck in the search of business flow control information, potentially causing delays in data packet forwarding
[0007] On the other hand, combined with the specific implementation of the network and business requirements, some data packets can be processed according to the traditional routing and forwarding strategy, and it is not necessary to be processed by the controller to save the processing cost of the controller. technically impossible

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] In order to solve the problems existing in the prior art, the embodiment of the present invention proposes a hybrid SDN network architecture that includes both the SDN network architecture and the conventional network architecture. Identification information to determine the forwarding direction of the data packet, and when the contract relationship identification information indicates that the data packet needs to enter the SDN network for processing, send the data packet to...

Abstract

The embodiment of the invention discloses a data packet processing method, device and system. According to the technical scheme, a mixed SDN (software defined network) structure including an SDN network structure and a common network structure is achieved; a mixed router device determines a forwarding direction of data packets according to the subscription identity information carried by the received data packets. Therefore, compatibility of an SDN network and a common network can be achieved; meanwhile, the data packets are associated with service requirements, standard SDN treatment can be performed on certain data packets, and the others data packets can save SDN network and related network element treatment, further the treatment cost of a controller can be saved, the network structure can be optimized, and high flexibility can be provided for treatment of the data packets.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data packet processing method, device and system. Background technique [0002] In the current SDN (Software Defined Network, software-defined network), the router is only responsible for the forwarding function of IP data packets, and the forwarding strategy is decided by the controller (Controller) network element. Under the framework of the network system, any IP data packet entering the SDN network will have its forwarding policy sent to the controller to determine the subsequent forwarding path and related operations of the data packet. [0003] Considering that most of the existing network equipment does not support the Openflow (a new network switching model) standard switch defined by SDN, if the entire network is upgraded to support SDN, it will require a large amount of investment. At the same time, considering the application of SDN itself Scenarios, i...
