Software definable network business configuration method

Abstract

Conventional network business disposition is very complex, so an operator needs to plan a service path in advance, and manually configures strategies for each node on the service path; different from the conventional network, the software definable network business configuration method comprises the following steps: on one aspect, a control layer possesses a global network resource view, thus easily planning the service path according to the service requests; on the other aspect, the control layer uses a southbound interface to gather and manage physics switch nodes in the data layer, thus automatically configuring the physics switch node strategies.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a software-definable network service configuration method. Background technique [0002] A computer network usually consists of a large number of routers, switches and network middleware with various functions. In order to effectively manage the network, administrators formulate various policies according to the services carried by the current network (such as: video, language, Web, etc.). Due to the lack of available tools, administrators need to manually convert these advanced policies into devices that can be used by network devices. Identifying low-level configuration commands can be challenging and error-prone. [0003] Another almost insurmountable difficulty for network practitioners and researchers is the "ossification" of the Internet. The huge deployment scale of the Internet makes it a key infrastructure in society. With the continuous expan...

Problems solved by technology

Of course, as an alternative solution to the "ossified" problem of the Internet, a large number of network function boxes (such as firewalls, intrusion detection systems, and address translators, etc.) can be placed on the basic interconnection at the bottom of the network, but such For managers, the management cost is too high, which is the current last choice
