Specifically, first apply for information (Query) is sent by line concentrator to multiple access means multicast, by being confirmed whether to be confirmed whether to exist from the report message (Report) of access means the access means (following, Query, Report to be called MLD frame) wishing to carry out receiving.
Then, line concentrator is broadcasted multiple access means, wishes the access means obtaining information received, and does not wish that the access means received then gives up information (such as non-patent literature 1).
But, in the method, line concentrator and do not wish that the frequency band service efficiency between the access means carrying out receiving is lower.
For this reason, in order at line concentrator and not wish between the access means carrying out receiving service band effectively, have employed proxy response (proxy: agency) (such as non-patent literature 2).
Agency refers to, when being confirmed hope by line concentrator and carrying out the access means received, by sending to information source the dispensing that MLD frame asks Multicast Flows (Multicast Flows being called that MC flows below) by line concentrator, thus the access means multicast dispensing MC only carrying out receiving to hope flows.Thus, having can in line concentrator and the advantage of not wishing effectively service band between the access means carrying out receiving.

Access means 31 is positioned at the coverage of the next line concentrator 11, and the next line concentrator 11 is connected with co-level line apparatus 21.Co-level line apparatus 21 is connected with information source 50.
The next line concentrator 11 comprises agent processes portion 111 and filter house 112.Co-level line apparatus 21 comprises agent processes portion 211 and filter house 212.
Agent processes portion 111,211 pairs, agent processes portion MLD frame carry out agent processes.
Filter house 112, filter house 212 pairs of MC streams filter.
Then, action when utilizing the existing line concentrator of said structure to carry out agent processes is described.
Received the MLD frame (dispensing request) sent from access means 31 by the next line concentrator 11, utilize 111 pairs, agent processes portion filter house 112 to carry out the filtering settings of the MLD frame for handling object.
The MLD frame having carried out agent processes by the next line concentrator 11 is transferred to co-level line apparatus 21.Then, again carry out agent processes by agent processes portion 211, filtering settings is carried out to filter house 212.
Be transferred to information source 50 by the MLD frame after co-level line apparatus 21 carries out agent processes, information source 50 sends the MC corresponding with MLD frame and flows.
MC stream is filtered by filter house 112, filter house 212, is then transferred to desired access means (being access means 31 in this explanation).
If as described above by multistage for existing line concentrator connection, then Fig. 2 illustrating as utilized, needing separately agent processes to be implemented to each line concentrator and carrying out filtering settings.Therefore, upper line concentrator, the load of agent processes is larger.
Then, the line concentrator involved by embodiment of the present invention 1 is described.
Fig. 3 ~ Fig. 6 illustrate by the line concentrator of embodiment of the present invention 1 as shown in Figure 1 multistage connect into chain time structure and the control flow of essence.In addition, Fig. 3 ~ Fig. 6 is major part enlarged drawing when utilizing the line concentrator of embodiment of the present invention 1 to carry out agent processes, and the part etc. for the part for access means in the coverage of each line concentrator, the internal structure of line concentrator has carried out suitable omission.In addition, for by line concentrator be chain carry out two-stage connection situation be described, but as described above, also can connect more than three grades.
The structure of Fig. 3 to the line concentrator of embodiment of the present invention 1 is utilized to be described.
Access means 31 is positioned at the coverage of the next line concentrator 12, and the next line concentrator 12 is connected with co-level line apparatus 22.Access means 41 is positioned at the coverage of co-level line apparatus 22, and co-level line apparatus 22 is connected with information source 50.
The next line concentrator 12 comprises agent processes portion 121, filter house 122, agentbased control portion 123 and filtering settings portion 124.Co-level line apparatus 22 comprises agent processes portion 221, filter house 222, agentbased control portion 223 and filtering settings portion 224.
Agent processes portion 121,221 pairs, agent processes portion MLD frame carry out agent processes.In addition, also agent processes load condition notice is sent to the agentbased control portion in this line concentrator.
Filter house 122, filter house 222 pairs of MC streams filter.
Agentbased control portion 123 is regular Receiving Agent disposal load condition notice from agent processes portion 121, agentbased control portion 223 from agent processes portion 221 regular Receiving Agent dispose load condition notice, according to load condition, agency is sent to the agentbased control portion of other line concentrator and implements notice or without the need to agent advertisement.In addition, implement notice if receive agency from the agentbased control portion of other line concentrator or without the need to agent advertisement, then this notice is sent to the agent processes portion of this line concentrator.
Filtering settings portion 124 receives the filtering settings notice of the MLD frame after agent processes from agent processes portion 121, filtering settings portion 224 receives the filtering settings notice of the MLD frame after agent processes from agent processes portion 221, the filter house of connection object to the filter house of this line concentrator and other line concentrator according to MC stream carries out filtering settings.
Then, Fig. 4 ~ Fig. 6 is utilized to be described the agent processes that the line concentrator of embodiment of the present invention 1 carries out.In addition, lower and higher to the load of agent processes respectively situation is described.
Fig. 4 is the figure of the control flow of essence when representing the load of agent processes lower (the agent processes performance of line concentrator still has surplus energy relative to processing load situation).As an example, the situation sending MLD frame from the access means 31 in the coverage of the next line concentrator 12 is shown.
When the load of agent processes is lower, the agentbased control portion 223 of co-level line apparatus 22 receives the agent processes load condition notice of load this meaning lower representing agent processes from agent processes portion 221.So agentbased control portion 223 sends without the need to agent advertisement to the agentbased control portion 123 of the next line concentrator 12.
The agentbased control portion 123 received without the need to agent advertisement sends without the need to agent advertisement to agent processes portion 121.Agent processes portion 121 receives without the need to after agent advertisement, then no longer implement agent processes (becoming closedown).
Be under the state of closing in the agent processes portion 121 of the next line concentrator 12, the MLD frame sended over from access means 31 without agent processes, and carries out agent processes by the agent processes portion 221 of co-level line apparatus 22 agent processes portion 121.
The filtering settings of the MLD frame after agent processes notice is sent to filtering settings portion 224 by agent processes portion 221.
Filtering settings portion 224, based on the filtering settings notice received, carries out filtering settings to the filter house 122 of filter house 222 and the next line concentrator 12.
Be sent to information source 50 by the MLD frame after agent processes portion 221 carries out agent processes, information source 50 sends the MC corresponding with the request of MLD frame and flows.
MC flows through and is sent to desired access means (being access means 31 in this explanation) by the filter house 222 of co-level line apparatus 22, the filter house 122 of the next line concentrator 12.
When the agent processes load that Fig. 4 is such is lower, the situation higher with agent processes load described later is same, also considers agent processes to be distributed in the next line concentrator.But, if will agent processes disperse when agent processes load is lower, even if then such as there is the MC stream of providing and delivering in upper line concentrator, also can carry out the dispensing request of same MC stream from the line concentrator of bottom, agency's function originally may be hindered, namely frequency band uses efficiently.In other words, unify process to same dispensing request, this has the higher advantage of efficiency in the MC frequency band use of banising when sending.
Then, action during the higher state of agent processes load is switched to be described to the state lower from the agent processes load shown in Fig. 4.
Fig. 5 is the figure of the control flow of the essence represented when switching to higher state from the state that agent processes load is lower.As an example, the action of following situation is shown: except the dispensing request that the access means 31 in the coverage from the next line concentrator 12 is sent, also send MLD frame from the access means 41 in the coverage of co-level line apparatus 22, because the agent processes load of co-level line apparatus 22 is higher, therefore make agent processes transfer to the next line concentrator 12, disperse agent processes load.
First, except from except the dispensing request of access means 31, also produce the dispensing request from access means 41, the MLD frame that agent processes portion 221 receives becomes the state exceeding the defined threshold relevant with agent processes number.
Agent processes load condition notice is sent to agentbased control portion 223 by agent processes portion 221, if according to this agent processes load condition notice, agentbased control portion 223 is judged as that agent processes load has exceeded threshold value, then the agentbased control portion 123 to the next line concentrator 12 sends agency's enforcement notice.
The agentbased control portion 123 receiving agency's enforcement notice implements to notify to agent processes portion 121 transmission agency.If agent processes portion 121 receives agency and implements notice, then become and can implement agent processes (becoming startup).
Therefore, the filtering settings notice can implementing to be undertaken by filtering settings portion of 121 pairs, agent processes portion 124 and the filtering settings undertaken by 124 pairs, filtering settings portion filter house 122 and filter house 222 is become.
Then, the action of following situation is described: namely, having shifted from co-level line apparatus 22 to the agent processes of the next line concentrator 12 shown in Fig. 5, become the state being implemented agent processes by the next line concentrator 12, make co-level line apparatus 22 no longer implement the agent processes of the MLD frame that (closedown) receives from the next line concentrator 12 thus.
Fig. 6 is the figure of the control flow of the essence represented when the agent processes of co-level line apparatus 22 being stopped.Namely, as the follow-up of control flow using Fig. 5 to represent, following action is shown: agent processes is transferred to the next line concentrator 12 from co-level line apparatus 22, makes the function stop (closedown) in the agent processes portion 221 of the co-level line apparatus 22 originally implementing agent processes.
In the next line concentrator 12 starting agent processes, agentbased control portion 123 is from agent processes portion 121 Receiving Agent processing load condition notification.So agentbased control portion 123 sends without the need to agent advertisement to the agentbased control portion 223 of upper line concentrator 22.
The agentbased control portion 223 received without the need to agent advertisement transmits without the need to agent advertisement to agent processes portion 221.If agent processes portion 221 receives this without the need to agent advertisement, then no longer implement the agent processes (becoming closedown) of MLD frame in the MLD frame received from co-level line apparatus 22, that receive from the next line concentrator 12.
As mentioned above, under the state that agent processes is distributed to the next line concentrator 12 from co-level line apparatus 22, agent processes is carried out.Namely, the agent processes of the MLD frame that access means 31 sends be can't help co-level line apparatus 22 and is carried out, and undertaken by the next line concentrator 12, in addition, accept the agent processes in the next line concentrator 12 and by the filtering settings portion 124 of the next line concentrator 12, with filter house 222 both sides, the filtering settings relevant with this MLD frame carried out to filter house 122.
It is noted herein that, can't help in Fig. 6 (closedown) agent processes portion 221 implement agent processes to as if the MLD frame that receives from the next line concentrator 12, and (opening) agent processes is implemented to the MLD frame that the access means 41 in the coverage from co-level line apparatus 22 receives.
Namely, after making agent processes load, the next line concentrator 12 only carries out agent processes to the MLD frame from the access means 31 in self coverage, and co-level line apparatus 22 only carries out agent processes to the MLD frame from the access means 41 in self coverage.
In addition, from the dispersed State Transferring of agent processes load shown in Fig. 6 for shown in Fig. 4 carry out the state of agent processes by co-level line apparatus 22 is unified time, become following flow process.
After access means 41 stops sending MLD frame, agent processes portion 221 sends to agentbased control portion 223 and represents that the agent processes load condition that the load of agent processes reduces this meaning (this meaning of the second defined threshold lower than relevant with agent processes number) notifies.
So agentbased control portion 223 sends without the need to agent advertisement to the agentbased control portion 123 of the next line concentrator 12.In addition, agentbased control portion 223 sends agency and implements notice, to process the MLD frame from the access means in the next line concentrator 12 coverage to agent processes portion 221.
Thus, afterwards, as utilized illustrated by Fig. 4, being unified to carry out agent processes by co-level line apparatus 22, carrying out filtering settings by 224 pairs, filtering settings portion filter house 222 and filter house 122.
As mentioned above, according to the present embodiment 1, multiple line concentrator is being configured in multistage communication system, multiple line concentrator can be utilized to carry out control agent process, therefore have and can disperse the load of agent processes and the effect that the line concentrator with handling property same can be applied to large-scale communication system.
And, due to filtering settings can be carried out when not carrying out agent processes to each line concentrator to other line concentrator, therefore there is following effect: the load of agent processes can be suppressed to increase, when not affecting the function of the such agency's script of effective use frequency band, frequency band can be effectively utilized.
In addition, the repetition of the agent processes produced in line concentrator in the past can be eliminated, the situation lower and higher to agent processes load can provide most suitable proxy processing method respectively.
Execution mode 2.
In above-mentioned execution mode 1, show the catenulate situation of multistage for multiple line concentrator connection.When connecting in chain, the next line concentrator be directly connected with a co-level line apparatus is one, namely annexation one to one.
In present embodiment 2, be N number of (N is the natural number of more than 2) to the next line concentrator that a co-level line apparatus is directly connected, be described by the multistage star-like situation connecting into the annexation with 1:N of multiple line concentrator.
Fig. 7 illustrates the overall structure figure of communication system when connecting into star-like by the line concentrator in coverage with multiple access means.
The multiple access means 30 be made up of access means 31 and access means 32 are connected to the next line concentrator 10.In addition, access means 31 and these two access means of access means 32 have been shown in Fig. 7, but the quantity forming the access means of multiple access means 30 can be arbitrary.
The multiple access means 70 be made up of access means 71 and access means 72 are connected to the next line concentrator 60.In addition, access means 71 and these two access means of access means 72 have been shown in Fig. 7, but the quantity forming the access means of multiple access means 70 can be arbitrary.
The multiple access means 40 be made up of access means 41 and access means 42 are connected to co-level line apparatus 20.In addition, access means 41 and these two access means of access means 42 have been shown in Fig. 7, but the quantity forming the access means of multiple access means 40 can be arbitrary.
The next line concentrator 10 and the next line concentrator 60 are connected with co-level line apparatus 20.Co-level line apparatus 20 is connected with information source 50.
In addition, shown in Fig. 7, the star-like of the annexation of 1:2 that have that the next line concentrator 10 and the next line concentrator 60 are connected with co-level line apparatus 20 is connected, but also can carries out star-like connection with the annexation of 1:N.
Connect into shown in star-like line concentrator with above-mentioned execution mode 1 same in present embodiment 2, comprise agentbased control portion and filtering settings portion.
When multiple line concentrator is connected into star-like, when acting on behalf of processing load and being lower, also by not implementing (closedown) agent processes cause co-level line apparatus 20 unified implementation agent processes in the next line concentrator 10, the next line concentrator 60.Thus, effectively frequency band can be utilized.
On the other hand, when the agent processes of co-level line apparatus 20 is higher, the next line concentrator 10 implements agent processes to the MLD frame from multiple access means 30, the next line concentrator 60 implements agent processes to the MLD frame from multiple access means 70, co-level line apparatus 20 does not implement agent processes to the MLD frame received from the next line concentrator 10 and the next line concentrator 60, disperses agent processes thus.
When chain connects, if line concentrator to be connected into more than 3 grades, then except the line concentrator of upper and lowermost position, also need to consider the control system of an and co-level line apparatus that this line concentrator is directly connected and the next line concentrator, the altogether agent processes of two line concentrators.On the other hand, when star-like connection, even if increase the next line concentrator, also remain in the next line concentrator and the connection of co-level line apparatus (there is not the line concentrator more the next than this next line concentrator), also remain in co-level line apparatus and the connection of the next line concentrator (there is not the line concentrator more upper than this co-level line apparatus), therefore the control system of agent processes situation about connecting than chain is simpler.
As mentioned above, according to the present embodiment 2, can utilize and obtain the effect same with above-mentioned execution mode 1 than the control system of the simpler agent processes of above-mentioned execution mode 1.
In addition, the present application can carry out independent assortment to each execution mode in its scope of invention, or is out of shape any inscape of each execution mode, or omits the arbitrary inscape in each execution mode.
