Method for generating IEEE1394 (Institute of Electrical and Electronics Engineers 1394) network topological graph

Abstract

The invention discloses a method for generating an IEEE1394 (Institute of Electrical and Electronics Engineers 1394) network topological graph, which comprises the steps of obtaining a physical identifier and port state information of each node in a network and judging the connection relation of the nodes on the basis of the port state information of the nodes in sequence according to an ascending sequence of the physical identifiers; obtaining an unique static identifier of each node; generating and saving a data structure of the connection relation among the nodes according to the connection relation and the unique static identifiers of the nodes; and generating a network topological graph according to the data structure of the connection relation among the nodes. Because the network topological graph can be automatically generated, an administrator can have an intuitive aware of the network connection situation according to the topological graph so that the connection state and the relative positions of the nodes in the network can be conveniently mastered. In addition, because the topological graph is automatically generated according to the connection relation of the nodes, the topological graph can be also updated in real time while the connection state among the nodes is changed so that the administrator can obtain the latest network distribution information in time.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for generating an IEEE1394 network topology map. Background technique [0002] By analyzing the network topology, administrators can understand the connection status and relative positions of each node in the IEE E1394 network. And when a node fails, the fault location is realized through the display of the topology map, and then the network layout is adjusted. [0003] However, in the prior art, there is no implementation scheme for automatically generating the IEEE1394 network topology map. If there is no network topology map, it is impossible to intuitively understand the connection status and error information of nodes in the network. It is necessary to obtain the required information by reading node information, which preempts the bandwidth resources of service information and affects network performance. If the administrator manually draws the topol...

Problems solved by technology

If there is no network topology map, it is impossible to intuitively understand the connection status and error information of nodes in the network. It is necessary to obtain the required information by reading node information, which preempts the bandwidth resources of business information and affects network performance.

If the administrator manually draws the topology map, it will not only increase the labor cost, but also cannot guarantee the real-time update of the topology map according to the network structure changes
