Preferred as one, receive the network coordination frame that other power on and the host node of networking sends, enter bandwidth negotiation and refer to the bandwidth duration by retaining in Frame, the broadband holding time of statement concentrator host node own net, by the bandwidth end mark retained in Frame, the bandwidth end time of statement concentrator host node own net.
After adopting above method, the present invention is compared with prior art, have the advantage that by arranging monitoring and buffering time period, the network designation of the host node that the network designation of the host node of non-networking completes with networking is compared, if occurring consistent, show there is conflict, the network designation of the host node of non-networking network designation again, the network designation of host node carrying out again completing with networking compares, until no longer there is conflict in network designation, the concentrator host node of non-networking afterwards starts networking work, so can allow for multi-network coexisted, thus ensureing that network communication is usual.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of Multi net voting internetwork coordination method for power wire broadband carrier communication network of the present invention, it includes the concentrator host node that networking completes in the bandwidth carrier communication network that power common line is carrier, for in bandwidth carrier communication network, other power on but the network coordination frame of the host node of non-networking monitoring the transmission of concentrator host node cycle, wherein, this network coordination frame includes
Network identity territory: comprise the network identity in the bandwidth carrier communication network that master node network identifies and host node receives;
Step one: when after the concentrator host node initial power-on of a non-networking, stochastic generation network identity;
Step 2: the network in bandwidth carrier communication network is carried out the monitoring that duration is T1 by the concentrator host node of non-networking, in this listening period section, receive the network coordination frame in bandwidth carrier communication network, if the master node network mark in the network identity territory in network coordination frame is consistent with the network identity of the concentrator host node of non-networking, show that network identity exists conflict, then enter step 3, otherwise jump to step 4;
Step 3: enter and consult, the concentrator host node of non-networking sets the duration negotiation phase buffer as T2, in this negotiation phase buffer, the concentrator host node of non-networking continues to monitor the network coordination frame in bandwidth carrier communication network, no matter whether the mark of the master node network in bandwidth carrier communication network is consistent with the network identity of the concentrator host node of non-networking, all consulting phase buffer to after date, concentrator host node B regenerates new network identity, then jumps to step 2;
Step 4: the concentrator host node of non-networking starts networking work.
The described concentrator host node that networking completes in bandwidth carrier communication network also can periodically in bandwidth carrier communication network, other power on and the host node of networking sends network coordination frame, this network coordination frame includes
Network identity territory: comprise the network identity in the bandwidth carrier communication network that master node network identifies and host node receives;
Frame; Described Frame includes the bandwidth end mark that the network needs for representing host node place apply for whether the bandwidth duration of bandwidth time length taken and the last bandwidth cycle of network for representing host node place are over.
Networking completes in bandwidth carrier communication network concentrator host node monitors in bandwidth carrier communication network the network coordination frame that other power on and the host node of networking sends, receive the network coordination frame that other power on and the host node of networking sends, enter bandwidth negotiation, in order to orderly the staggering of the bandwidth of heterogeneous networks.
Receive the network coordination frame that other power on and the host node of networking sends, enter bandwidth negotiation and refer to the bandwidth duration by retaining in Frame, the broadband holding time of statement concentrator host node own net, by the bandwidth end mark retained in Frame, the bandwidth end time of statement concentrator host node own net.
Wherein, bandwidth negotiation is deferred to following principle and is included keeping out of the way principle, FEFO priority principle and little network identity priority principle,
Wherein, keep out of the way principle and refer to: if host node 1 and host node 2, when host node 1 can receive the internetwork coordination frame of host node 2, but host node 2 does not receive the internetwork coordination frame of host node 1. If host node 1 finds the bandwidth time section to take, host node 2 also states the bandwidth time section to take, and the airtime section of host node 2 comes into force, and host node 1 needs to avoid the airtime section of host node 2, takies other time slot bandwidth.
FEFO priority principle refers to: if the whole airtime section of host node 1 network terminates prior to host node 2 network, then host node 1 network can terminate without waiting for host node 2 network, can preferentially take, namely continue to start next airtime section.
Little network identity priority principle: when the cycle of host node 1 network and host node 2 network terminates simultaneously, the bandwidth occupancy of the network of network identity less (airtime section is short) comes into force, the network of network identity relatively big (airtime segment length), it is necessary to keep out of the way the bandwidth application of the less network of network identity.
In sum, Multi net voting internetwork coordination method of the present invention, under multi-network coexisted environment, after internetwork coordination, it is to avoid interfere between each network, it is ensured that the reliable communications of network, it is achieved that stablizing of network.
It is described as far as highly preferred embodiment of the present invention above, but is not to be construed as limitations on claims. The present invention is not limited only to above example, and all various changes made in the protection domain of independent claims of the present invention are all in protection scope of the present invention.
