Embodiment two
Fig. 8 is the structural schematic diagram of the route network of alternative embodiment according to the present invention, as shown in figure 8, whole network contains
There is the routing of six communication apparatus, all equipment requires to route by root and the external world communicates.In addition, other than routing 5,
Remaining 5 equipment is all equipment existing for original, and routing 5 is the equipment being added in the later period.Root routing is whole network correspondence with foreign country
Unique channel.
Application scenarios one: the foundation of route network.In emergency system, when equipment is destroyed, need promptly to introduce
New communication apparatus routes and establishes communication connection, and routing 1 to routing 4 has 4 equipment altogether and establishes road according to network physical position
By connecting, here it is the initialization of network connection.Routing 1, routing 2 with root routing at a distance from be all 2 units, they directly with
Root routing connection, completes initialization with the root routing nearest equipment of physical distance in this way.Routing 3 can choose routing 1 or routing 2
Any one establishes connection, and the physical distance of routing 3 and root routing in this way is most short, it is assumed that company is established in final route 3 and routing 1
It connects.The connection with routing 3 is established in routing 4, although routing 4 is minimum by the hop count of 2 connection root routing of routing, according to physics
Apart from nearest principle, the connection with routing 3 is established in routing 4.It can thus be seen that the process that new route network initializes
The process exactly constantly expanded outwardly from root routing does not need complicated software algorithm, it is only necessary to the physics of communication apparatus
Position.
Application scenarios two: the introducing of new communication apparatus routing.Existing network needs new be added to route 5, according to most short
Distance algorithm, routing 5 directly establish initial connection with routing 4.If former according to the routing minimum hop count in usual software algorithm
Then, routing 5 needs to know the connection of remaining routing in network, establishes the connection with routing 1, routes 5 in this way to root routing
Hop count it is minimum.The software algorithm of this complexity, needs to know the connection state of whole network.And it is related to this alternative embodiment
And method, routing 5 is by directly establishing connection with routing 4, so that it may existing network rapidly be added.
Application scenarios three: routing connection is destroyed in network.Disconnecting between routing 3 and routing 1.Route 3, road
It still can not mutually be communicated between them with root route communication by 4, routing 5.Current routing 2 is recently from them
Routing establishes connection between routing 3 and routing 2, and routing 4 and routing 5 do not need to do any work, can restore entire net
Network.It is this using most short physical distance as the routing algorithm of foundation, fast and effeciently guarantee network it is unobstructed.
Field higher for route handoff time requirement is waited in military affairs, using the route handoff side in this alternative embodiment
Method can establish new routing connection fast and reliablely.Compared with the equipment based on routing table in the related technology, this equipment disappears
The resource of consumption greatly reduces, while algorithm is simple, has certain superiority.When constructing route network, using this optional reality
The device in example is applied, traditional route protection device is replaced, route protection cost can be reduced, improves the effect of Route establishment switching
Rate.
The above is only alternative embodiments of the invention, are not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
