Problems solved by technology

In such an IEEE 1394 serial bus network as shown in FIG. 1, if a transmission rate difference occurs between adjacent nodes, the efficiency of a high-speed node (for example, 200 Mbps) will be lower than that of a low-speed node (for example, 100Mbps) and reduce

Embodiment Construction

[0012] The following will combine Figure 3A describe the process of optimizing the topology of the IEEE 1394 serial bus, Figure 3A Six nodes respectively providing transmission rates of 100 Mbps, 200 Mbps, and 400 Mbps (hereinafter referred to as "rates") are shown. Labels 0, 1, and 2 represent the number of ports for each node. First, refer to figure 2 , in step 110, the bus controller detects the number of ports and the speed of each node. Next, at step 110, the bus controller judges whether the sum of the port numbers is equal to or greater than 2(N-1), where "N" represents the number of all nodes. This is to verify that all nodes can be connected to the serial bus. In this embodiment, the number N of nodes is 6, and the total number of ports is 11, so the preconditions of step 110 are satisfied. In step 130, each node is prioritized according to the rate and the number of ports. In this case, consider the speed first, and then the number of ports. Such as Figure...

Abstract

A method of optimizing the topology of the IEEE 1394 serial bus having a plurality of nodes each with communication ports, comprises the steps of prioritizing the nodes according to the number of the ports and the transmission speed, connecting a non-used port of the node of the first priority with a port of the node of the second priority, and repeating the previous step until all of the nodes are connected together, whereby the nodes are connected through the ports according to priority order.

Description

technical field [0001] The present invention relates to IEEE 1394 networks, and more particularly to a method for optimizing the topology of the IEEE 1394 serial bus. Background technique [0002] IEEE 1394 is a next-generation multimedia interface for exchanging information between various multimedia devices in accordance with the regulations established by IEEE (Institute of Electrical and Electronics Engineers). A serial bus standard between multimedia devices such as HD-TV, DVD, and DVC. This interface is different from the traditional interface that only allows connections between personal computers and peripherals such as mice, printers, and scanners. Through the practice of engineers in electronics, communications and computers, IEEE 1394 technology has achieved rapid development, and currently can provide data transmission rates up to 400Mbps (megabits per second), plug and play (plug & play) systems and 63 nodes on a single bus, etc. [0003] In order to optimize ...
