Summary of the invention
The invention discloses a kind of IP-free routing method that is applicable to wireless broadcast channel; Make up wireless network through a plurality of wireless route exchange devices: in the Routing Protocol of route exchange device, be device identification that the whole network is unique of each wireless route exchange device configuration; All preset planning subnet route in each wireless route exchange device, record the equipment identification information routing iinformation corresponding in the planning subnet route with each device identification; IP header section in the message is rejected, and with the source address of device identification as message; During message transmission, the source address information in the wireless route exchange device analytic message, the device identification that obtains being correlated with is handled message according to the planning routing iinformation; The corresponding routing iinformation of said each device identification is also referred to as the planning routing iinformation.
The byte number that said device identification takies is 4 bytes.
Said a plurality of wireless route exchange device makes up Radio Link; Comprise; The corresponding a plurality of wave points of single wireless route exchange device; Through wave point communication,, and be not wave point distributing IP address between the wireless route exchange device for each wave point in the single route exchange device distributes a unique interface identifier in this wireless route exchange device.
The byte number that said interface identifier takies is 1 byte.
During described message transmission, the source address information in the wireless route exchange device analytic message, the device identification that obtains being correlated with is handled message according to the planning routing iinformation, comprising:
When wireless route exchange device sends message; The device identification of local wireless route exchange device is sent with message as the source address information of message, and do not comprise the subnet route that relates in the planning file of storing in the indicated routing iinformation of this device identification and this equipment in the routing iinformation;
When wireless route exchange device receives message; If do not comprise the source address of this message in the route network segment in the message; The route main frame route that then to add one be purpose and gateway with this message source address, and transmit the not variation routing iinformation among planning by the planning routing iinformation; If include this message source address in the route network segment in the message, then directly transmit the not variation routing iinformation among planning by the planning routing iinformation.
Described by planning the not variation routing iinformation among planning of routing iinformation forwarding; Comprise: if the routing cost of the destination address of message is not maximum; Then add this route in the converting route in wireless route exchange device; Simultaneously, the all-ones subnet of the equipment of this route indication subnet route as message source equipment is added in the converting route;
If the routing cost of the destination address of message is a maximum; Then delete this route in the converting route in wireless route exchange device; Simultaneously, the all-ones subnet of the equipment of this route indication is deleted from corresponding converting route as the all-ones subnet route of message source equipment.
Useful technique effect of the present invention is: provide a kind of and made the wireless network method for routing of reorganization arbitrarily, and routing cost is little.
Embodiment
In the prior art, wireless Routing Protocol requires route exchange device interface that the Radio Link equipment in the same subnet connected in same IP subnet, and each equipment in the network is discerned through IP each other; But actual conditions are that owing to some artificial or unartificial former thereby occurring network reorganization, the IP of route exchange device can't be discerned by other equipment after the network reorganization Radio Link equipment, causes communication disruption through regular meeting.
The IP-free routing method that is applicable to wireless broadcast channel that the present invention proposes; Same needs make up wireless network through a plurality of wireless route exchange devices; But the difference of itself and prior art is: in the Routing Protocol of route exchange device, be device identification that the whole network is unique of each wireless route exchange device configuration; All preset planning subnet route in each wireless route exchange device, record the equipment identification information routing iinformation corresponding in the planning subnet route with each device identification; IP header section in the message is rejected, and with the source address of device identification as message; During message transmission, the source address information in the wireless route exchange device analytic message, the device identification that obtains being correlated with is handled message according to the planning routing iinformation; The corresponding routing iinformation of said each device identification is also referred to as the planning routing iinformation.The drawback of having avoided the network reorganization back equipment that equipment causes through IP identification in the prior art to discern.The byte number that said device identification takies is 4 bytes.
The corresponding a plurality of wave points of single wireless route exchange device; Pass through wave point communication between the wireless route exchange device; For each wave point in the single route exchange device distributes a unique interface identifier in this wireless route exchange device, and be not wave point distributing IP address.
After wireless network brings into operation by the method for routing of preamble; When wireless route exchange device sends message; The device identification of local wireless route exchange device is sent with message as the source address information of message; Opposite equip. only need be discerned device identification, and the information of the corresponding device sign in the planning subnet route of noting gets final product.When wireless route exchange device receives message: if do not comprise the source address of this message in the route network segment in the message; The route main frame route that then to add one be purpose and gateway with this message source address, and transmit the not variation routing iinformation among planning by the planning routing iinformation; If include this message source address in the route network segment in the message, then directly transmit the not variation routing iinformation among planning by the planning routing iinformation.Wireless route exchange device is when sending and receive; To the processing of message source address information, in fact be exactly a process that new route is learnt, after this has guaranteed the network reorganization; Can set up new routed path between the equipment, thereby guarantee the lasting communication after the network reorganization.
The routing cost of each routed path that writes down in the planning subnet routing iinformation all is in allowed limits; But after the network reorganization, the new routed path that equipment is set up through study might make routing cost surpass permissible value; At this moment just need be optimized the very big path of route expense; Specifically, be exactly:, then add this route in the converting route in wireless route exchange device if the routing cost of the destination address of message is not maximum; Simultaneously, the all-ones subnet of the equipment of this route indication subnet route as message source equipment is added in the converting route;
If the routing cost of the destination address of message is a maximum; Then delete this route in the converting route in wireless route exchange device; Simultaneously, the all-ones subnet of the equipment of this route indication is deleted from corresponding converting route as the all-ones subnet route of message source equipment.This has effectively been avoided the excessive problem of new routing cost that causes because of networking again.
