Embodiment Construction

[0079] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0080] The invention is mainly applied in the field of network communication. The following are the technical terms involved:

[0081] SDN: Software Defined Networking, which is a software-defined network, is an innovative new network architecture compared to traditional networks, aiming to completely separate the data plane and control plane of network equipment;

[0082] MPLS label: MPLS uses labels to forward data. When a packet enters the network, it is assigned a fixed-length short label, and the label is encapsulate...

Abstract

The invention discloses an end-to-end service monitoring method based on an SDN. The method comprises the following steps: performing path query on a service to be monitored to obtain the informationof each node on a path of the service; packaging a specific packet_out message according to the attributes of the service; on the basis of matching the specific packet_out message with a service stream, matching a specific flag bit; issuing the packet_out message to a head end node of the service, and meanwhile starting a timer of the service; finally forwarding the packet_out message to a tail end node of the service; and after a packet_in message sent by the tail end node is received, parsing the packet_in message at the same time, calculating the delay of the path of the service, and resetting the timer of the service, wherein the packet_in message is packaged by the tail end node according to the received packet_out message information. By adoption of the end-to-end service monitoringmethod disclosed by the invention, the end-to-end monitoring of the service is achieved, the normal forwarding of the data traffic of the service is not affected, the performance requirements of a controller are not increased, and the end-to-end service monitoring method can be applied to a large SDN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for end-to-end service monitoring based on an SDN network. The present invention also relates to an end-to-end service monitoring device based on an SDN network. Background technique [0002] SDN network (Software Defined Network) is a software-defined network. It is a new network innovation architecture proposed by the clean slate research group of Stanford University in the United States. Its core technology, OpenFlow, separates the control plane of network equipment from the data plane. It realizes the separation of software and hardware and the virtualization of the underlying hardware, thereby realizing the flexible control of network traffic and providing a good development platform for the innovation of core network and applications. [0003] In SDN, the data forwarding layer and control layer of switching equipment are separated, so the upgrade of...
