Description
Technical field
The present invention relates to a kind of method for routing and system, and in particular to a kind of distributed load equalizing route based on content
Method and system.
Background technology
With the development of satellite network, satellite communication is sent out by individual layer Satellite Networking mode (low earth orbit, LEO)
Open up as multilayer Satellite Networking mode (Geo-synchronous earth orbit, GEO).Individual layer Satellite Networking mode refers to
Constellation is formed by the satellite of same rail height.Multilayer Satellite Networking mode is referred to by two or more multiple orbital attitudes
Satellite forms constellation.Multitiered network networking mode solves the bottleneck of single layer network satellite communication, extends the model of network service
Enclose.
The routing issue of satellite network is its subject matter to be solved.For the rational network road of LEO/GEO network designs
It is the study hotspot of current satellite network to meet the communication of dynamic satellite network by algorithm.Due to satellite and terrestrial user phase
The feature such as sudden of continuous change to position, the uneven characteristic of terrestrial user business segment and communication time period, leads
Cause the flow load of satellite network unbalanced, therefore, solve the problem of load balancing of LEO/GEO networks, and its is to be solved
Subject matter.
Routing mechanism main at present is divided into three kinds:Load balancing routing policy based on source node, based on Centroid
Load balancing routing policy, distributed load equalizing routing policy.
1) the load balancing routing policy based on source node realizes simple that all routing mechanisms are by LEO/GEO networks
In the source node uniquely specified carry out policy development, but lack and the overall situation of network considered, the reality of flow information can not be ensured
Shi Xing, signal overhead are also higher;
2) the load balancing routing policy based on Centroid, it is contemplated that the overall situation of network, use the entirety of global network
Network topological information and flow information carry out the formulation of routing policy, but the signal overhead of Centroid is higher, and can not be real
The scalability of existing network network;
3) it is based on distributed load equalizing routing policy, the full distributed progress routing policy of all nodes in network
Formulate, each node carries out the formulation of routing policy using the local message of real-time update, and this method being capable of rapid development route

Generation set;
The current congestion degree for each route being related in the set is calculated, selects the minimum road of Congestion Level SPCC
By the Optimization route forward-path as flow information.
It is described that routing policy is formulated according to the flow information of service request, including:When the type of service is data service
If flow status judge current layer Congestion Level SPCC δ in Shi Jinhang layers<During predetermined threshold (predetermined threshold 80%), then formulation layer
Interior routing policy, handled in individual layer Satellite Networking mode layer, otherwise formulate interlayer routing policy, service request is submitted
Handled to multilayer Satellite Networking mode layer.
It is LEO/GEO network architecture diagram as shown in Figure 1.The service request of terrestrial user is sent to LEO satellite layer, LEO
Satellite layer carries out processing forward to flow caused by business, and the business that LEO satellite layer can not be handled is transferred at the GEO layers of upper strata
Reason.The present invention, which puies forward route, can be divided into route in layer, interlayer route.Route refers to the routing policy inside LEO layers in layer,
Interlayer route refers to the routing policy formulated in LEO and GEO interlayers.
As shown in Fig. 2 be the flow chart of routing policy of the present invention generation, including:
1) judge that this formulates route plan in interlayer routing policy or layer as the flow according to the content of flow information first
Slightly.Judge whether the business is voice service, if voice service, because its delay requirement is higher, it is entered in LEO layers
Row processing;If data service, because its delay requirement is relatively low, flow status in layer are carried out again and are judged, if current LEO
Layer Congestion Level SPCC is relatively low, then is handled in LEO layers, otherwise submit to GEO layers and handled.
2) routing policy formulating method in layer:Business is marked, according to service label, service request divided
Class, and " route experts database in layer " is searched, if corresponding route in experts database be present, according to the destination address of the route
Business route is forwarded.If corresponding route is not present in experts database, routing mechanism carries out route judgement to business route.
3) route determination methods are service request source address during current business is route, service request destination address, are built
Vertical " route mapping graph ", according to service requester destination address, to currently available route, is combined, selects route
The minimum route of flow, as the Optimization route under current state.Meanwhile according to uninterrupted, after the route is chosen, by this
Flow in route is overlapped.
4) by the Optimization route of generation, according to message label, it is added to " route experts database in layer ".
5) interlayer routing policy formulating method:According to business purpose address, calculate and currently arrive at location, route congestion
The minimum route of degree, directly carries out routing forwarding.
Flow information content format in routing mechanism is as shown in table 1 below:
Flow information content format in the routing mechanism of table 1
Business Name | Service label | Service request source address | Service request destination address | Uninterrupted |
This paper institutes extracting method is in each satellite of LEO and GEO layers, and specific route implementation method is as follows:
The service request that terrestrial user is sent is labelled, service label, to the industry of Different Ground user requestor
Business is parsed, and analyzes its business tine, and using the numerical value of the uninterrupted in business tine as message label, be placed into and disappear
Cease in head.Judge the message for route in layer or interlayer route.
According to the source address S of service request, destination address D, service label T, " route experts database in layer " is searched, if specially
There is the route met in family, then carry out message forwarding according to the route in storehouse.
If qualified route is not present in experts database, new route is generated.Generating the method newly routeing is:According to
The destination address D of service request, judge that all routes of location, generation set can be arrived at.
In set P, the Congestion Level SPCC of each route is calculated according to flowmeter, selects the minimum road of Congestion Level SPCC
By the forward-path as the flow.
This is route, according to service label T and source address S, is added to " interlayer route experts database ".
The formulation of interlayer routing policy, because the number of satellite of GEO layers is less, therefore, directly calculate current source address energy
Get at up in all paths of destination address, the minimum route of Congestion Level SPCC, as forward-path.
