Non-SDN (Software Defined Network) equipment interconnection device and method

Abstract

A non-SDN (Software Defined Network) equipment interconnection device comprises a network construction module, a detection module and a control module. The network construction module is used for constructing a SDN network. The detection module is used for detecting whether or not a plurality of pieces of non-SDN equipment access to the SDN network. The control module is used for connecting the plurality of pieces of non-SDN equipment through the SDN network when the plurality of pieces of non-SDN equipment access to the SDN network. The invention also provides a non-SDN equipment interconnection method. The invention enables interconnection among non-SDN equipment to be flexible, transparent and intelligent.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an interconnection device and method for non-SDN (Software Defined Network, software-defined network) equipment. Background technique [0002] Software-defined networking is a new type of network architecture. By separating the control plane and the forwarding plane of the underlying network equipment, the flexible control of network resources and the flexible deployment and software definition of the underlying equipment are realized. It can be divided into SDN devices whose control plane and forwarding plane can be separated and non-SDN devices whose control plane and forwarding plane cannot be separated. [0003] At present, in some industries that are highly dependent on IT systems, such as governments, public institutions, banks, securities and other units, it is often necessary to perform complex and flexible interconnection of various network devices, many of which are ...

Problems solved by technology

There are many problems with this working method: when connecting, people need to go to the site to do the wiring (low efficiency and error-prone); because physical cables or traditional network devices are used for interconnection, the traffic between non-SDN devices cannot be seen after interconnection. It is also difficult to carry out fine-grained control of traffic (poor visibility, difficult fine-grained control); personnel located in different physical locations (such as branches) cannot share IT resources in different places, and cannot be scheduled, condition-triggered, and automated operations (cannot be automated, remote In many cases, the same device cannot be shared with multiple personnel at the same time. When the connection relationship needs to be changed, personnel need to go to the site to change the connection, and it is even impossible to automatically switch the connection (such as automatic topology switching test, link road flash test)

Also for cloud service providers, because their tenants use the network randomly and dispersedly, the traditional fixed-configuration network needs to reserve network resources for all users, which wastes network resources and makes high-value users The quality of service (QoS) cannot be fully satisfied, and network resources cannot be dynamically allocated according to information such as tenant usage, network resource congestion, and tenant payment levels.
