Embodiment Construction

[0035] Fig. 1 is a schematic diagram of an adjacent space multi-protocol label switching network system according to some embodiments of the present invention. As shown in Fig. 1, the system includes a user layer and an adjacent space network layer, wherein the user layer is composed of user nodes, and the adjacent space network The layer consists of access nodes and forwarding nodes. Any router on the access node or forwarding node includes a network edge router module and a label switching router module. The above router modules include a control plane and a forwarding plane. The control plane includes an air control unit. and ground control unit.

[0036] User nodes are users who need to initiate multi-protocol label switching (MPLS) service applications. These users may include fixed users, low- and medium-speed mobile users (handheld and vehicle-mounted mobile devices), and high-speed mobile users (missiles, drones, etc.); Business types may include: voice, data, multimed...

Abstract

The invention relates to a proximity space multi-agreement label exchange network system. The system includes a consumer layer and a proximity space network layer. The proximity space network layer consists of access nodes and transmitting nodes. A router on any access node or transmitting node includes a network edge router module and a label exchange router module. Both the network edge router module and the label exchange router module include a control plane and a transmitting plane. The control plane includes an air control unit and a ground control unit. The air control unit and the ground control unit alternate the control information through an air-ground signaling interface. The system adopts the mode of air-ground integrated cooperative processing which can better solve the contradiction between limited resources and capabilities of a proximity space aircraft node and the requirements of high performances and a plurality of functions. Besides, the invention also relates to a processing method of the proximity space multi-agreement label exchange network system.

Description

technical field [0001] The present invention relates to a multi-protocol label switching network system, in particular to a multi-protocol label switching network system integrated with space and ground in adjacent spaces; The invention relates to a processing method for an air-ground integrated multi-protocol label switching network system; it belongs to the communication field. Background technique [0002] With the maturity of near-space vehicle technology, the networking among near-space vehicles and the integrated design between near-space networks and other networks (such as space-based and ground-based networks) have become the hotspots in the development of near-space communication systems. [0003] The near-space network uses airships and other levitators as the core nodes (hereinafter referred to as near-space nodes). Taking advantage of its flexible deployment, relatively large coverage, and smaller transmission delay than satellites, it provides a wider range of ...
