Embodiment Construction

[0025] The present invention can detect the delay information of the data message from the source node to the destination node or to each intermediate device, including the outbound transmission delay, the node processing delay, the output buffer queuing delay, and the return transmission time It can also detect related system information and interface information, including CPU utilization, memory occupancy, interface type and maximum transmission unit.

[0026] image 3 It is a flow chart of a method for acquiring transmission information of nodes on a transmission path in the present invention.

[0027] In step 301, synchronizing the network time of the source node and the destination node can be realized by running the Network Time Protocol (Network Time Protocol, NTP) on the source node and the destination node. way, and record the sending timestamp of the message in the IP header option field of the Ping message sent by the source node to the destination node.

Abstract

The invention provides a method and a device for acquiring node transmission information on a transmission path. The method comprises: network time of a source node and a target node are synchronized, when the source node transmits a Ping message to the target node, the transmission time of the message is recorded in the IP header option field of the Ping message; after the Ping message reaches the target node, at least one of the following information is recorded: the IP header option field which copies the transmission time to the Ping reply message, the time when the target node receives the Ping message, the time when the Ping reply message is generated, the time when the Ping reply message is transmitted, the CPU occupancy rate the memory occupancy rate, the interface type and MTU when the Ping reply is generated. At least one of the above information is transmitted to the source node; and according to the transmission time of the source node, the receiving time of the target node, the generation time and the transmission time, the delay information is calculated and CPU utilization rate, the memory occupancy rate, the interface type and the MTU are extracted. The invention can easily and effectively acquire relevant delay information system information and interface information of each node in the transmission path,.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a method and equipment for acquiring transmission information of nodes on a transmission path in a communication network. Background technique [0002] The existing data communication network detects network faults through the Ping (Packet Internet Groper) command. Ping commands are provided on general routers and Layer 3 switches. Generally speaking, the Ping command is to check whether the network between two devices is connected by sending several ICMP (Internet Control Message Protocol) echo request messages to the destination device in the network, and then listening to the ICMP echo response messages returned by the destination device. [0003] In the field of telecommunication, especially in the NGN (Next Generation Network) network, some services have high requirements on the service quality of the network, for example, voice service, IPTV service and so on....
