Embodiment Construction

[0051] In computer networks, DPDK serve to focus on high performance processing network application packet. DPDK embodied in the application is running using the data provided in the plane of the library itself to send and receive data on the user space. Compared with traditional packet processing mode, DPDK service has many advantages. Therefore, DPDK service is typically used to implement Linux Virtual Server LVS (LinuxVirtualServer), Source Network Address Translation SNAT (Source Network AddressTranslation) and other services, typically deployed L3_Switch interconnection and three switches. Three switches and DPDK cluster using OSPF ECMP protocol and deployment. like figure 1 As shown, three switches to achieve an ECMP load balancing among the plurality of nodes DPDK, such DPDK1 and DPDK2, perceived by the node service state DPDK OSPF protocol, when a service failure, and remove the node from the routing table driving traffic to other nodes, so as to ensure the flow is not int...

Abstract

The invention discloses a network node fault detection method, device and system. The method applied to the network node comprises the steps that under the condition that session connection between the network node and a switch is established, the network node sends a first control message to the switch through the session connection, and the first control message is at least used for the switch to monitor whether the network node breaks down or not; the network node monitors whether a second control message sent by the switch through the session connection is received within a preset first duration; and under the condition that the network node does not receive a second control message sent by the switch through the session connection within the first duration, the network node outputs afirst detection result to the switch, and the first detection result represents that the network node has a fault.

Description

Technical field [0001] The present application relates to computer network technology, and more particularly relates to a network node failure detecting method, apparatus and system. Background technique [0002] Usually DPDK (Intel Data Plane Development Kit) service as a unified whole cluster to provide services outside. Wherein, DPDK cluster network node by a set of services running DPDK composition. Specifically, the three switches DPDK Clusters equal-cost multi-path routing ECMP (Equal-Cost Multipath Routing) and Open Shortest Path First OSPF (Open Shortest Path First) deployed mode, based on this, through the three switches in the ECMP load balancing, traffic balancing and DPDK introduced to the network node in the cluster, and the three switches in the network node dynamically perceived failure of the cluster through DPDK OSPF protocol, when a fault occurs on the network service node, from the routing table remove the node traffic and leads to the other nodes to ensure the...
