Embodiment Construction
[0029] The method of the present invention monitors the on-off status and the congestion situation of the whole path in real time through the agent between the networks between the satellite links, once the satellite node and the link are switched or congested, the agent between the networks can quickly monitor this problem and communicate with Forward and backward information exchange between adjacent nodes, quickly rebuild a new optimal path. The protection strategy of the present invention includes three aspects of routing reconstruction problems: inter-satellite handover, satellite-ground handover, and congestion control. Monitor network resource dynamics and link failures through the inter-network Agent. There is an inter-network Agent between every two satellite nodes on the existing path to monitor link switching information and congestion status. The inter-network Agent and the front and rear phases Adjacent nodes can exchange information. Once a link is switched or co...

The invention relates to a dynamic route service quality protection method for safe agent-based satellite network mainly for solving the problem of route reconstruction when the safe agent-based satellite network link fails. In the protection method, full-path reselection of the path for protecting the link and the node is not required, but only partial updating of the route is required, an original path map still needs to be maintained at the satellite node with unchanged link, and the path is reconstructed at the part where the service path fails; when the network fails, inter-network agent can feed back the information to the key path node in time, so that the key path node suspends sending service data stream to avoid the loss of the data package; after the success of route reconstruction, the sending of the data package is continued, the constructed path is maintained and updated continuously, and the obtaining of the routing information is timely; therefore, the protection to the QoS route is well realized.
Description
Technical field: [0001] The invention is a service quality protection method of satellite network dynamic routing based on safety agent, which is mainly used to solve the problem of route reconstruction when link failure occurs in the satellite network based on safety agent, and belongs to the technical field of network survivability. Background technique [0002] The routing algorithm and protocol of the satellite network must not only operate efficiently and reliably, but also provide better QoS (Quality of Service) and security guarantees. Traditional routing and switching technologies cannot meet the special needs of satellite networks in terms of reliability, security, and on-board conditions; nor can they provide routing and switching equipment under strict restrictions on power and weight and network topology changes. The QoS guarantee mechanism does not have the ability to quickly self-reorganize the network when the network structure is severely damaged. At present...
