Detailed in addition to embodiments of the invention below with reference to accompanying drawings explanation.Fig. 1 and Fig. 2 are respectively the block diagram of an embodiment of connection state information dispensing device of the present invention and connection status video data generating apparatus.And Fig. 3 is the block diagram of the protocol architecture of IEEE 1394.
Among Fig. 3, the protocol architecture of node 21 comprises IEEE 1394 interfaces 22, API23 and display layer 24.IEEE 1394 interfaces 22 comprise three 1394 layers of physics and link layer 25, processing layers 26 etc., also are provided with bus management equipment 27 simultaneously.
Physics and link layer 25 are the interface of physical layer and link layer, in physical layer, transmit also carry out when the coding of data and decoding, bus arbitration are handled and medium between interface handle, in link layer, carry out the transceiver and the periodic Control of packets of information.
The transmission of processing layer 26 regulation instructions and the agreement of reception.Processing layer 26 is by transmitting the transmitting-receiving of data between the transmission medium (IEEE 1394 buses) that does not have among physics and link layer 25 and the figure to show.
Processing layer 26 is by carrying out the transmission of data, instruction and function between API23 and the display layer 24.API23 is the interface that application program is utilized the service of operating system etc., and 24 of display layers provide the management and the user interface of hardware.Such as, when display layer 24 has the display part,, can show according to connection status video data by the API23 input if carried out standardization to connecting video data.
And, there is not the IEEE1394 interface 22 of specific on IEEE 1394 buses of an expression node to be provided with bus management portion 27 in the drawings.Bus management portion 27 is used to carry out node control and bus management, such as optimal control, power management, transmission speed management and the structure management of the control of carrying out cycle master, performance.By control, can realize the communication between the node to node.
In IEEE 1394, each node is with the daisy chain or tree-shaped that is connected to like that described above.When power connection,, and the information (link information) relevant with the connection status of node carried out initialization to bus reset.To the node initialization time, it himself is the branch node that is connected with other several nodes, or leaf node that only is connected with a node or the information that is in notconnect state that each node all has.
In case bus is reset in IEEE 1394, at first carry out the identification of topology.Promptly all port (hereinafter referred to as father port) of leaf node by being connected with branch node behind bus reset will send expression by the father notice of child node to parent node notice.Branch node will be represented to be sent to the son notice of the notice of child node by the parent node by the port (hereinafter referred to as subport) that receives information after receiving father's notice.Come to determine two set memberships between the node thus.
In addition, with port that other nodes link to each other in, those have both confiscates the branch ports node that father's notice is not received the son notice yet, sends father's notice by this port.The node that at first receives father's notice between port in two nodes that will connect is as the parent node, and another then is a child node.
After this promptly carry out same processing repeatedly, the last parent node of determining is as root node in bus.After carrying out bus identification, carry out the identification of the identifier of node.
That is, when the node identifier of the node that the little port of those and sequence number is linked to each other gave less label, also the node identifier for the node that is connected with lower level gave less label to each node at the label of the port of the node of each layer.Therefore, comprise that the node of each layer of root node is connected with the port of sequence number minimum, counting the node identifier that is positioned at undermost leaf node by root node is 0.At the node identifier is the branch node on the upper strata of 0 node when a child node is only arranged, and the node identifier of this branch node is 1; When it had plural child node, the node identifier of the leaf node that is positioned at the orlop position that links to each other with the port of label minimum then was 1.
The node identifier is 0 node, at first announces the own node of other nodes and is designated 0.Secondly the number of the identifier information bag of other node self node that will be received by other nodes in moment of announcement is as the node identifiers of oneself.By above-mentioned order, each node is announced the node identifier of self, and makes all nodes obtain the announcement of own node identifier.
Each node utilizes the tagging packets of information to transmit the identifier of self node.Fig. 4 is the structural representation that this target is known packets of information.
As shown in Figure 4, the stem of tagging packets of information is " 10 ", thereafter, and for representing the Phy-ID " 0 " of self node identifier, " L ", gap-cnt, sp, del, c, pwr, p0, p1, p2, i, m; The logical inversion signal in initial side district (quadrate) is set in following 32.In the tagging packets of information, P
0, P
1, P
2Be two, represent the state of three ports respectively, " 11 " expression links to each other with child node, and " 10 " expression links to each other with the parent node, and " 01 " is then represented to link to each other with other nodes, and " 00 " then represents not have port.Again, when each node has port more than four, the P of transmission expression port status in side district thereafter

4...
Has the bus manager that does not have expression among the figure in the bus management portion 27.Bus manager receives by all nodes and transmits the self identification packets of information, the topological diagram of the side district set when generating as all tagging packets of information initial.
Among Fig. 1, link information reading circuit 2 is used for the information of the topological diagram 1 that the bus manager of read bus management equipment 27 generates.The link information reading circuit outputs to parent node designation list generative circuit 3 with the information of reading.
Fig. 5 and Fig. 6 are the key diagram of parent node designation list generative circuit 3.
Be illustrated in the state when being connected to six nodes of #0 to #5 on the bus among Fig. 5.Again, in the example of Fig. 5, with the label of the numeral port of symbol P back.Each node of #0 to #5 utilizes the recognition methods of above-mentioned node identifier, to the given identifier 0 to 5 of each node.The node identifier is that 5 node is a root node.
With regard to each node, only there is a parent node, but the experimental process node is arranged.Therefore, parent node designation list generative circuit 3 can be calculated the identifier of the parent node of each node in order to grasp connection state.Parent node designation list generative circuit 3 is at first checked the identifier of the child node of each node, and calculates the parent node of each node in view of the above.
As mentioned above, the data P in the tagging packets of information
0, P
1, P
2When linking to each other with child node, each port is " 11 ".Parent node designation list generative circuit 3 at first checks that to nodes all on the network its Port State Table registration is according to P
0, P
1, P
2, and the subport number that is connected with child node (below be referred to as the subtree number) counted.
Such as, the data P that comprises in the self-identifying packets of information by node # 3 output
0, P
2Be " 11 ", the subtree number that parent node designation list generative circuit 3 detects node # 3 is 2.The information of the subtree number of each node that the example parent node designation list generative circuit 3 of presentation graphs 5 calculates in the following table 1.
Table 1
| The node identifier | ????0 | ????1 | ????2 | ????3 | ????4 | ????5 |
| The subtree number | ????0 | ????0 | ????1 | ????2 | ????1 | ????1 |
Following parent node designation list generative circuit 3 is checked the node that the node that subport is arranged promptly has child node according to the junction label size sequence, calculates the node identifier of sub-tubercle.The identifier of child node is that parent node identifier subtracts 1 when its parent node only has a subport.To the example of Fig. 5, can be as seen from Table 1, node # 0, #1 do not have subport.And be that the node identifier is 1 node # 2 in the table 1 with first node of junction label size sequence with subport.Because the subnumber of node # 2 is 1, the child node corresponding with this node is node identifier (=2-1) the node # 1 that is 1.
Below, whether 3 couples of next node # 3 of parent node designation list generative circuit have subport inspection.Node # 3 has two subports as shown in Figure 1.Therefore to node # 3, the node identifier of at least one child node is than the 3 node # 2 that only lack 1 (being 2).And also have a child node for node # 3, i.e. its node identifier node littler than node # 2, and be not the child node of other nodes.Because node # 1 is the child node of node # 2, then another child node of node # 3 is 0 node # 0 for the node identifier.
Parent node designation list generative circuit 3 adopts same program, and the sequence number of node is checked the node identifier of the child node of each node by ascending order.In example shown in Figure 5, as shown in table 1, because the subtree number average of node # 3 and node # 5 is 1, the node identifier of the child node of their node is respectively 3,4.
Parent node designation list generative circuit 3 is calculated the node identifier of each child node of each node by this way.Any node of 3 pairs of parent node designation list generative circuits beyond digging up the roots utilizes its fact that links to each other with a parent node at least, from the information of the child node that is connected with each node, asks the relation of the node identifier of each node and its parent node conversely.Table 2 provides the relation of each node and its parent node.
Table 2
| The node identifier | ????0 | ????1 | ????2 | ????3 | ????4 |
| Parent node identifier | ????3 | ????2 | ????3 | ????4 | ????5 |
Fig. 6 represents the connection status of eight node # 0 to #7 on the bus.In this embodiment, each node # 0 to #7 utilizes the recognition methods of above-mentioned node identifier, and the identifier of each node is decided to be 0 to 7 respectively.The node identifier is that 7 node is a root node.
In this example, parent node designation list generative circuit 3 is at first checked the identifier of the child node of each node, calculates the parent node of each node in view of the above.That is, the data P of its port status is represented in all the node inspections on 3 pairs of networks of parent node designation list generative circuit
0, P
1, P
2, calculate its subtree number.
Following table 3 shows the subtree of each tubercle that is counted to get by the parent node designation list generative circuit 3 in the example shown in Fig. 6 and counts information.
Table 3
| The node identifier | ????0 | ????1 | ????2 | ????3 | ????4 | ????5 | ????6 | ????7 |
| 3 tree numbers | ????0 | ????0 | ????1 | ????0 | ????3 | ????0 | ????1 | ????2 |
Then, parent node designation list generative circuit 3 is checked the node with subport by node sequence number size sequence, calculates the node identifier of child node.For the example of Fig. 5, as can be seen from Table 3, node # 0, #1 do not have subport.Its postjunction # 2 is because the subtree number is 1, and the child node of this node is node identifier (=2-1) the node # 1 that is 1.Node # 3 does not have subport.Node # 4 is as shown in table 3, has three subports.Node # 4 has the node # 3 of its node identifier of a child node than 4 only little by 1 (being 3) at least.Again, two child nodes beyond the node # 3, the little node of node identifier of node # 4 for this reason, and be not the child node of other nodes, node # 2 and node # 0 are its child node as can be seen in the table 3.
By same program, parent node designation list generative circuit 3 is undertaken by the node identifier of junction label size sequence to the child node of each node.For the example of Fig. 6, as shown in table 3, the child node of node # 6 is node # 5, and the child node of node # 7 is node # 6 and node # 4.
Parent node designation list generative circuit 3 is obtained the relation of node identifier between each node and its parent node according to the node identifier of the child node of each node of calculating.Below table 4 provide the relation between each node and its parent node in the example of Fig. 6.
Table 4
| The node identifier | ????0 | ????1 | ????2 | ????3 | ????4 | ????5 | ????6 |
| Parent node identifier | ????4 | ????2 | ????4 | ????4 | ????7 | ????6 | ????7 |
Parent node designation list generative circuit 3 outputs to connection status video data generative circuit 4 to the information that concerns between the identifier of the node of expression generation and parent node.
Connection status video data generative circuit 4 is according to the information of input, and generation has the connection status video data of predetermined data format, and outputs to formating circuit 5.Formating circuit 5 with the input the connection status video data be transformed to the transmission data form and with its output.
Fig. 7 A is the connection status format of display data, the transmission data format of Fig. 7 B.
Shown in Fig. 7 A, connection status video data generative circuit 4 is in 8 bit representation node identifiers, the identifier of the parent node of this node identifier is also represented with 8, the data of each node and its parent node are made up generate the connection status video data.Again, the numeral in the bracket of Fig. 7 A is the identifier of node in the example of Fig. 5.
Fig. 7 B is the structural representation of the asynchronous information bag of IEEE 1394.The asynchronous information bag is to constitute by the arrangement of stem, stem CRC (cyclic redundancy school sign indicating number sign indicating number), data and data CRC.Formating circuit 5 is arranged on the connection status video data data division of the asynchronous information bag of IEEE 1394.Formating circuit 5 also is arranged on the connection status video data in the asynchronous information bag and transmits.
Data by formating circuit 5 transmission output to IEEE 1394 buses that do not have expression among the figure by terminal 6.And the connection status video data of connection status video data generative circuit 4 outputs is directly exported by terminal 7.
Among Fig. 2, the transmission data by IEEE 1394 bus transfer output to transmission data decoding circuit 11 by terminal 9.Transmit data decoding circuit 11 the asynchronous information bag of input is unpacked, the connection status video data that is arranged on data portion is outputed to connection status view data generative circuit 12.
Again, also by terminal 10 places input connection status video data, at this moment, the connection status video data of terminal 10 inputs is directly outputed to connection status view data generative circuit 12 sometimes.
Connection status view data generative circuit 12 generates the view data of representing network connection state by the connection status video data of input, and it is supplied to display circuit 13.
Such as, connection status view data generative circuit 12 generates connection status view data shown in Figure 5 after the input of the connection status video data shown in Fig. 7 A.That is, by size the order and the identifier of parent node thereof arranged in the connection status video data; Connection status view data generative circuit 12 is represented node according to the order (node identifier size sequence) that is provided with in the mode of square frame, the square frame that generates its parent node of expression is also connected, after this corresponding connection status video data is sequentially arranged square frame, and connected, generate the view data of expression connection status.
In addition, in connection status view data generative circuit 12, also may be by the information of terminal 8 each passing node equipments of input.So-called facility information is by the machine name of each equipment and the icon of indication equipment formations such as (graphical informations).In the WG of IEEE 1394, IEEE 1212 is defined in and leaves the memory space (configuration ROM) that can be read by other equipment in the memory space of each equipment, with inputs such as the icon informations of implementor name and equipment wherein, as facility information, can utilize by sense information in this memory space.
Connection status view data generative circuit 12 can generate the view data of indication equipment title and appliance icon according to the facility information that is provided by terminal 8 input equipment information the time.
In addition, formating circuit 5 and transmission data decoding circuit 11 are realized together by processing layer 26 and physics and link layer 25.

Like this, in the present embodiment, at transmitter side, generating the parent node designation list of the identifier relation of each node of expression and its parent node according to topological diagram, is the connection status video data with tentation data form with the information conversion of this parent node designation list.At receiver side, by the transmission connection status video data that obtains of data or directly obtain the connection status video data, generate the view data of expression connection status by the connection status video data.Therefore, if there is the node with function that the view data that generated by the connection status video data shows in network, no matter what equipment each node has, or transmitter side and receiver side be not at same node, or the display device difference, can be to show connection status with a kind of form.
Therefore, it is very effective making display layer and API generalization.
Specifically, the present invention can provide a kind of node by the bus manager with topological diagram information to provide the method that shows connection status with display device from the simplest transmission data to the node of the display device that does not have above-mentioned functions.
Again, in the above embodiments for the node with connection status view data generative circuit 12 to the example of the facility information read by other nodes in addition explanation, and have the node that the node of bus management portion 27 also can have the function of connection status view data generative circuit 12 with the facility information input of being read by other nodes.
That is, each circuit of Fig. 1 and Fig. 2 can constitute in arbitrary node, and also can constitute in arbitrary position of inter-node.Thus, each circuit of Fig. 1 and Fig. 2 also can be realized with software.And for example, connection status view data generative circuit 12 and display circuit 13 also can be arranged on other node.In addition, when the connection status video data being write the read-write memory space of institute's locking equipment, the node with connection status view data generative circuit 12 can be read the connection status video data of storing in this memory space.
Again, in the embodiment of Fig. 1 and Fig. 2, when the connection status video data of the relation of the identifier of the whole nodes that utilize display network and its parent node or transmission data, when increase and decrease taking place, can transmit the facility information of the equipment that is increased and decreased as the equipment in network.
That is bus resetted when, connection status changed in IEEE 1394.Like this,, utilize the function of (for example) bus manager etc., the facility information of the node before and after the bus reset is compared, detect the equipment of increase and decrease because the value of the identifier of each node may change.Because promptly there was equipment in the parent node of increase and decrease equipment before summary resets, can be only the facility information of the equipment of the facility information of the equipment of increase and decrease and this parent node be transmitted as the connection status delta data.
At this moment, connection status view data generative circuit 12 has memory, and the connection status delta data that utilizes new transmission can upgrade the connection status video data in the memory.Generate the view data of expression connection status again with the connection status video data after upgrading.
Like this, just can the connection status behind the bus reset be shown.
Figure 13 and Figure 14 are the block diagram of other embodiment of the present invention.Figure 13 is the connection state information dispensing device, and Figure 14 is a connection status video data generating apparatus.In Figure 13 and Figure 14, the device identical with Fig. 2 structure with Fig. 1 promptly omits the explanation to it with identical symbolic representation.
In the embodiment of Figure 13, different with the embodiment of Fig. 1 only is to substitute former connection status video data generative circuit 4 with connection status video data generative circuit 41.
Figure 15 A, Figure 15 B and Figure 16 represent connection status video data generative circuit 41 and formating circuit 5 respectively.Figure 15 A is a connection status video data formating circuit, and Figure 15 B is transmission data formatting circuit.And Figure 16 represents that #0 is to the connection status of 24 nodes of #23 on the bus.And, in the example of Figure 16, with number number of the numeral port of symbol P back.# 0 utilizes above-mentioned node identifier recognition methods to give 0 to 23 identifier respectively to node to each node of #23.The node identifier is that 23 node is a root node.
For the example of Figure 16, parent node designation list generative circuit 3 generates the parent node designation list shown in the table 5 according to the relation of the identifier of node and parent node.
Table 5
| The | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
| | 3 | 3 | 3 | 23 | 5 | 9 | 8 | 8 | 9 | 23 | 23 | 13 | 13 |
| The |
13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 |

22 | 18 | 17 | 17 | 18 | 22 | 20 | 22 | 22 | 23 |
Connection status video data generative circuit 41 results according to the parent node designation list upgrade the node identifier together.That is, connection status video data generative circuit 41, according to the value maximum of the identifier of root node, begin to the necessarily big rule of the identifier value of little identifier, parent node, upgrade together with the mode that can show identifier to node to the connection status of receiver side multilayer than the identifier value of child node by leaf.
In the example of table 5, connection status video data generative circuit 41 at first places the front with the identifier 23 of root node, and next is arranged the node identifier of the child node of this node # 23 by the size of sequence number.As shown in Table 5, be 3,9,10,22 node # 3 because the child node of node 23 is node identifiers, #9, #10, #22 is showing the 23 back configurations 3,9,10,22 of node identifier.
Secondly, by knot # 3, #9, #10, the order of #22 checks its child node, and with the child node identifier order assignment node identifier by size of child node.Because by table 5 as seen, the child node of node # 3 is that the node identifier is 0,1,2 node # 0, and #1, #2 promptly press the identifier of this sequence arrangement node.In addition, as shown in Table 5, the child node of node # 9 is that the node identifier is 5,8 node # 5, and #8 is so arrange the node identifier with this order.Again secondly, there is not child node by the visible node # 10 of table 5.The identifier of the child node of node # 22 is as shown in table 5 to be 13,18,20 and 21.
To node # 22, connection status video data generative circuit 41 is pressed node identifier 23,3,9,10, and 22,0,1,2,5,8,13,18,20,21 order is arranged the node identifier.
After this in the same way, connection status video data generative circuit 41 upgrades the node identifier together.After this promptly, connection status video data generative circuit 41, to node # 0, #1, #2, #5, #13, #18, #20, #21 checks its child node by this order, the node identifier order by size of the child node after the inspection is arranged the identifier of this node.
At last, connection status video data generative circuit 41 presses 23,3,9,10,22,0,1,2,5,8,13,18,20,21,4,6,7,11,1,2,14,17,19,15 to the node identifier in the table 5,16 sequence arrangement.
The identifier that connection status video data generative circuit 41 will upgrade together outputs to formating circuit 5 by the mode shown in Figure 15 A as the connection status video data with 8 arrangements respectively.
Figure 15 B is the structure of the asynchronous information bag of IEEE 1394.The asynchronous information bag is arranged by stem, stem CRC, data and data CRC and is formed.Formating circuit 5 is arranged in the connection status video data data division of the asynchronous information bag of IEEE 1394.Formating circuit 5 is arranged in the connection status video data in the asynchronous information bag and transmits.Data by formating circuit 5 transmission are delivered to IEEE 1394 buses that do not have expression among the figure by terminal 6.Also can directly export by the connection status video data of connection status video data generative circuit 41 outputs through terminal 7 again.
What the embodiment of Figure 14 was different with the embodiment of Fig. 2 has just replaced connection status view data generative circuit 12 with connection status view data generative circuit 42.
In Figure 14, the transmission data that transmit by IEEE 1394 buses are identical with the embodiment of Fig. 2, through terminal 9 input transmission data decoding circuit 11.Transmit data decoding circuit 11 the asynchronous information bag of input is unpacked, the connection status video data that will be positioned at data division offers connection status view data generative circuit 42.
Again, by terminal 10 places inputs connection status video data the time and the embodiment of Fig. 2 be directly inputted into connection status view data generative circuit 42 by the connection status video data of terminal 10 inputs equally.
Connection status view data generative circuit 42 generates the view data of expression network connection state by the connection status video data of input, and imports display circuit 13.
The key diagram of Figure 17 for connection status view data generative circuit 42 among Figure 14 is described.Figure 17 is corresponding to the connection status video data shown in Figure 15 A.
Such as, connection status view data generative circuit 42 promptly generates the view data of demonstration connection status shown in Figure 17 after the input of the connection status video data shown in Figure 15 A.Connection status view data generative circuit 42, the value that utilize the identifier of root node to have maximum value, to be begun to give the identifier of less identifier, parent node by leaf necessarily generates connection status shown in Figure 17 than the big rule of value of the identifier of child node and shows.
That is, the connection status of 42 pairs of inputs of connection status view data generative circuit shows that carrying out level judges.Connection status video data shown in Figure 15 A is the value by 23,3,9,10,22,0,1,2,5,8,13,18,20,21,4,6,7,11,12,14,17,19,15,16 tactic node.According to above-mentioned rule, the little part of identifier of the node of the ratio front of arranging in the data rows is the place of level layering.Be in the example of Figure 15 A, 23 → 3,22 → 0,21 → 4 and 19 → 15 are the place of layering.
Because node identifier 23 is the value of the identifier of maximum, so it is a root node.After, four the node identifiers 3,9,10,22 from node identifier 3 to node identifier 22 are the node of the second layer.And, after this be the 3rd layer node by node identifier 0 to 9 node identifiers 0,1,2,5,8,13,18,20,21 of node identifier 21.
After this in the same way, 42 pairs of connection status view data generative circuits represent which layer the node # 0 of node identifier 0 to 23 belongs to #23 and judge.In the example of Figure 15 A, node # 23 is a root, belongs to ground floor; Node # 3, #9, #10, #22 are the second layer, node # 0, #1, #2, #5, #8, #13, #18, #20, #21 are the 3rd layer; Node # 4, #6, #7, #11, #12, #14, #17 and #19 are the 4th layer, node #15, #16 then belong to layer 5.
Connection status view data generative circuit 42 generates expression is arranged in each node connection status of each layer to layer 5 by ground floor data as shown in figure 17.Which node on the node of 42 pairs of each layers of connection status view data generative circuit and its upper strata links to each other then, and promptly the parent node of each node is which node is judged.
According to above-mentioned rule, child node has little node identifier than parent node.The node of 42 pairs of each layers of connection status view data generative circuit, the node that carries out having in the node than its high one deck the node identifier bigger than this node is the judgement of its parent node.
Such as, the node of the second layer is node # 3, #9, #10, #22.The identifier of three-layered node point is child nodes of node # 3 than 3 little nodes.The 3rd layer node is node # 0, #1, and #2, #5, #8, #13, #20, #21, the child node of node # 3 is node # 0, #1 and #2 as can be seen.And the child node of node # 9 is the 3rd layer a node with node identifier big and littler than the identifier of node # 9 than the identifier of node #3.The child node that is node # 9 is node # 5, #8.
Connection status view data generative circuit 42 is checked the child node of all nodes equally, to represent set membership as line as shown in figure 17.Connection status view data generative circuit 42 will show the view data output of the connection status of Figure 17.
