Embodiment Construction
[0078] The embodiment of the present invention provides a method, device and system for detecting the connectivity of a service chain. The network device uses the detection event message to report the event of obtaining the detection data packet, and the monitoring server counts the detection event message, combined with the preset service chain. The flow entry is used to detect the fault location of the service chain.
[0079] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0080] figure 2 The flow chart of the service chain connectivity detection method provided by the embodiment of the present invention includes:
[0081] Step 201: The network device obtains the detection data packet.
[0082] A detection data packet for detecting connectivity of the service chain is generated in a service chain of a software defined network (Software Defined Network, SDN). The detection data packet is different fro...

An embodiment of the invention provides a business chain connectivity detection method, device and system. A network device acquires a detection data packet, generates a detection event message according to the detection data packet, reports the detection event message to a monitoring server and forwards the detection data packet to a next network device of a business chain detected by the detection data packet. The monitoring server respectively receives detection event messages transmitted by a plurality of network devices, acquires a preset business chain flow table item, and detects failure positions of the business chain according to the received detection event message and the flow table item. The network devices in the business chain generate the detection event message and report the event of acquiring the detection event message to the monitoring server, the monitoring server counts the detection event messages transmitted by the network devices, a detection forwarding path of the detection data packet in the business chain can be acquired, and the failure positions of the business chain can be detected according to the preset business chain flow table item.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for detecting service chain connectivity. Background technique [0002] In the field of fixed or mobile broadband access and data center applications, there are a variety of value-added service processing based on layers 4 to 7, including: antivirus, firewall, network address translation (Network Address Translation, NAT) and application caching and acceleration Wait. When networking, multiple service processing nodes are set up, and each service processing node can provide a value-added service processing function. [0003] For the service data flow received by the user access device, different types of service data flows need to perform different types of value-added service processing. If all the service data streams received by the user access device flow through all the service processing nodes sequentially, a large processing cap...
