Embodiment 1

[0063] The content-based distributed load balancing routing method and device of the present invention refers to the satellite nodes in the LEO / GEO network, which can dynamically change according to the traffic content, and adaptively generate a traffic routing line that satisfies the load balance. The traffic routing line follows the traffic The difference in content is automatically adjusted.

[0064] The present invention provides a content-based distributed load balancing routing method, the flow chart of which is as follows image 3 Shown, including:

[0065] The present invention provides a content-based distributed load balancing routing method, and its improvement lies in:

[0066] According to the content of the flow information and the size of the flow information, determine whether to implement the routing strategy within the LEO layer or the routing strategy between the GEO layers.

[0067] Preferred: Determine whether to implement the routing strategy within the LEO layer...

Embodiment 2

[0104] Based on the same inventive concept, the present invention also provides a content-based distributed load balancing routing system, including:

[0105] The strategy execution module is used to determine whether to execute the routing strategy within the LEO layer or the routing strategy between GEO layers according to the content of the flow information and the size of the flow information.

[0106] Further: the strategy execution module further includes:

[0107] The service type acquisition module is used to obtain the service type from the traffic information content;

[0108] The service label forming and module is used to form the service label of the traffic information according to the service type;

[0109] The execution module is used to determine the routing strategy within the execution layer or execute the routing strategy between GEO layers according to the service label.

[0110] Further: the service types include: voice service and data service.

[0111] Further: the...

Abstract

The invention relates to a distributed load balanced routing method and system based on content. The method comprises the steps of determining whether to execute a routing strategy within an LEO layer or the routing strategy within a GEO layer according to the content and size of flow information, a routing expert database in the layer is also provided, business routes are recorded according to difference of business types, and routing generation efficiency is improved. According to the method provided by the invention, routing selection is performed according to a current routing congestion degree, and an overall load balancing is achieved. The format of the business flow is optimized, a business label, a business request source address and a business request target address are added into business flow, and generation of the business routing is facilitated.

Description

Technical field [0001] The invention relates to a routing method and system, in particular to a content-based distributed load balancing routing method and system. Background technique [0002] With the development of satellite networks, satellite communication has developed from a single-layer satellite networking (low earth orbit, LEO) to a multi-layer satellite networking (Geo-synchronous earth orbit, GEO). The single-layer satellite networking mode refers to a constellation composed of satellites with the same orbital height. Multi-layer satellite networking refers to a constellation composed of two or more satellites with different orbital heights. The multi-layer network networking method solves the bottleneck of single-layer network satellite communication and expands the scope of network communication. [0003] The routing problem of the satellite network is its main problem to be solved. Designing reasonable network routing algorithms for LEO / GEO networks to satisfy the...
