Embodiment Construction

[0032] The principle of the present invention involves three problems: (1) The distributed deployment mode of the function service chain adopted in the ground network is not suitable for the satellite network based on the wireless link, how to deploy the network function service chain in the satellite network and implementation; (2) The business function arrangement in the ground network has high requirements for the intelligent processing level of the local controller. How to realize the unification of business functions for the satellite system that mainly focuses on transmission and switching functions and has a severely limited processing capacity Description and flexible arrangement; (3) The OpenFlow standard adopted in terrestrial SDN is mainly aimed at IP-based services, how to design a generalized flow table format for the diversified service requirements of various autonomous heterogeneous satellite systems.

[0033]The satellite network plays more of a basic service f...

Abstract

The present invention relates to a service architecture based on a virtual data plane and a method for providing services, so that the parallel implementation of multiple network function service chains can be simultaneously supported on the same satellite network device, avoiding the problem of multifunctional strategy combination; and in each In the VDP, different customized intermediate service function modules can be combined and enabled through standardized programming interfaces, so that the entire processing process of the network function service chain can be programmed and customized; each intermediate service function node of the present invention corresponds to one level The flow table unifies the format of each level of flow table, which solves the problems of flow table applicability and unified description of different intermediate business function nodes. At the same time, the deployment of intermediate service function nodes can be flexibly arranged, so that the network function service has the ability of flexible expansion and contraction; the unified description method of the satellite network service proposed by the present invention fully considers the characteristics of the limited on-board processing capacity of the satellite system, and is simple and efficient. , with engineering feasibility.

Description

technical field [0001] The invention relates to a service architecture based on a virtual data plane and a service providing method, which belong to the communication field. Background technique [0002] Satellite system is a typical limited system (weight, volume, power consumption, device selection, etc.), with long development cycle, high cost and high risk. Diversified business application requirements and rapidly evolving technologies have repeatedly magnified the shortcomings of traditional satellite systems that lack programmable capabilities, are difficult to change functions within the life cycle, and are difficult to arrange services on demand. To realize the function / service on-demand arrangement of the satellite network, a unified service description method is the foundation. [0003] The general service description model in NGN provides only an abstract description model of a service, and does not involve any specific implementation mechanism. The Web service ...
