If the number of ports is one, the node will
(Step S1603). here
A leaf is a node connected to only one node.
It is a word. A node serving as a leaf has a connection port
For the connected node, "I am a child (Cbil
d) "(step S1604).
At this time, the leaf sets the connection port to "parent port (parent
(Communication port connected to the node). Here, the declaration of the parent-child relationship is first made on the net.
Performed between the leaf and branch at the end of the work
And then sequentially between branches.
You. The parent-child relationship between each node is a communication that can be declared quickly.
Determined in order from the port. Also, between each node,
The communication port declared to be a child is the “parent port”.
The communication port that is recognized as
(Communication port connected to child node) "
It is. For example, in FIG. 14, nodes A, E, and F are:
After recognizing that you are a leaf, declare a parent-child relationship.
U. Thereby, the child-parent, node E
-D is determined as child-parent and between nodes FD is determined as child-parent.
It is. As a result of the processing in step S1602,
If the number of connection ports is two or more, the node
It is recognized as “branch” (step S160)
5). Here, a branch is connected to two or more nodes.
Node that is being used. A node serving as a branch is connected to each connection port.
A declaration of a parent-child relationship is received from the node (step S1)
606). The connection port that accepted the declaration
Is recognized. Recognizing one connection port as a “child port”
After the branch, the connection that has not yet been determined
Whether there are two or more connection ports (ie, undefined boats)
Is detected (step S1607). As a result, undefined
If there are two or more ports, the branch will step again
The operation of S1606 is performed. As a result of step S1607, the undefined port
If there is only one branch, the branch defines its undefined port
Recognizes that the port is a “parent port” and connects to that port.
Declared that "I am a child" for the node
(Steps S1608 and S1609). Here, the branch is the remaining undefined port
Until one becomes a child, the other node
Cannot be declared. For example, in FIG.
Nodes B, C and D recognize that they are branches
And receive declarations from leaves or other branches.
Attach. Node D is a parent-child relationship between DE and DF.
Is determined, a parent-child relationship declaration is made to node C.
ing. Node C, which has received the declaration from node D,
The parent-child relationship is declared to node B. As a result of the processing in step S1608,
If the defined port does not exist (that is,
All connection ports that are parent ports),
The branch recognizes itself as the root.
(Step S1610). For example, in FIG.
Node B that has become the parent port is the 1394 network.
Is recognized by other nodes as a route to mediate communication on
It is. Here, Node B is determined to be the root,
The timing at which the parent-child relationship of node B is declared
If it is earlier than the timing,
It could be the root. That is, when to declare
In some cases, any node can be the root.
Therefore, even in the same network configuration, the same node
Not necessarily the root. Thus, the parent-child relationship of all connection ports is
By being declared, each node is
Recognize work connection configuration as hierarchical structure (tree structure)
Can be performed (step S1611). Note that the above
The parent node is higher in the hierarchy and the child nodes are
It is lower in the layer structure. (8) Allocation of Node ID FIG. 17 shows the process of step S1505 shown in FIG.
(That is, the process of automatically assigning the node ID of each node
9 is a flowchart for explaining in detail). here,
The node ID includes a bus number and a node number.
However, in this embodiment, each node is connected on the same bus.
And the same bus number is assigned to each node
