Network management method and network architecture based on application and user mode protocol stack

Abstract

The invention discloses a network management method and network architecture based on application and user mode protocol stacks, the network architecture comprises an application layer, a TCP layer, a network layer and a controller, a ServiceIP layer is arranged between the TCP layer and the application layer, the application layer comprises a plurality of APPs, at least one user mode protocol stack is deployed in the ServiceIP layer, and the user mode protocol stack is used by more than one APP. The network management method comprises the steps that a controller receives an APP request sent by any APP, and the APP request is sent to the controller through a corresponding user mode protocol stack; and the controller processes the APP request and feeds back a processing result to the corresponding user mode protocol stack, and the corresponding user mode protocol stack sends the processing result of the controller to the corresponding APP. According to the method, the problems of identification, access, mobility and the like of the APP are solved, the deployment of the user mode protocol stack is more flexible, and the platform portability is high.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a network management method and network architecture based on application and user state protocol stacks in an SDN scenario. Background technique [0002] With the large-scale use of network devices, access users, and user APPs, the current development of the Internet has made traditional user-oriented network interfaces face more and more challenges. [0003] First of all, the traditional operating system socket interface uses the IP address + port as the locator for communication. As the address or port changes, it brings network shocks. As far as APP is concerned, it should not be aware of changes in IP addresses or ports. Moreover, it is currently impossible to hide the identity by using the IP address as the basic interface of the socket. For network eavesdroppers, during the entire transmission of the message, it can always be traced back to the source according to t...

Problems solved by technology

Moreover, it is currently impossible to hide the identity by using the IP address as the basic interface of the socket

For network eavesdroppers, during the entire transmission of the message, it can always be traced back to the source according to the identity of the IP address, so as to launch a corresponding attack

[0004] Second, the current kernel network connection mechanism is based on the IP address + port method, which cannot distinguish between different applications, and thus cannot perform application policy management, resulting in redundant transmission of network data and a great waste of network resources.

[0005] Third, there is currently no reasonable way for high-priority application requirements to be delivered to the network layer, so application-based requirements cannot be expressed on the network

However, HIT adopts the method of transforming the kernel protocol stack, and the transformation based on the kernel involves huge differences in kernel versions, which is difficult to promote. At the same time, due to the natural low efficiency of the kernel protocol stack, high latency, and no application SLA adaptation API of the application, etc. The technology is of little practical significance
