Embodiment Construction

[0034] The present invention decomposes network protocol functions into multiple atomic functions according to the three logical domains of connection, service quality and security, which are called meta-services. Several service containers are set on network nodes, and each service container manages and organizes a group with the same The protocol unit of the interface, each protocol unit corresponds to a meta-service, and completes the corresponding network function. The user increases the network service provided by the service container by deploying a new protocol unit to the service container, and provides the binary file of the protocol unit and the added Description of the network service, after the service container receives a new deployment request, it loads the protocol unit into the memory to run, and updates the service request parsing module of the service container according to the description of the network service, and the service request parsing module is used to ...

Abstract

The invention relates to an implementation method for network node structure supporting service customization and expansion, which comprises the following steps of: adopting a service container to replace the protocol stack in the traditional network system structure; adopting a deployable protocol unit and a dynamic combination thereof to replace the original series of protocols; providing a service interface for network application by the service container and receives the customizing request of the network application upon the network service, and the inner part realizes and provides the customizing service through an organization management unit; and providing a deployment interface to a service provider by the service container, dynamically loading or downloading the protocol unit, and implementing the dynamic expansion of the network function through the downloading of the protocol unit. In the invention, the network application can obtain the network service equal to the traditional network system structure and also can obtain more flexible service support by putting forwarding the service customization request facing to the requirements in the aspects of connection, service quality and the safety from the service container, and the service of the service container can be flexibly expanded.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and relates to a network node system, which is used to provide customizable and scalable network transmission services. It is a network node structure implementation method that supports service customization and expansion, and can be deployed on network end nodes or intermediate nodes. superior. Background technique [0002] The network architecture stipulates the information interaction, access control, connection mode and topology between network equipment and terminal equipment, and is embodied in a series of protocols and standards. The currently widely used TCP / IP five-layer network structure was formed in the 1970s. Its layered structure and based on the idea of ​​best effort and packet forwarding can better solve the design problems of complex communication protocols and provide certain scalability. and higher efficiency. [0003] With the development of Internet applications,...
