As shown in fig. 3, a schematic diagram of passive probe deployment and dial testing based on greedy algorithm.
(1) Test scene of internal network layer of EPON access network
The probe deployed in the OLT can periodically initiate network layer dial-test to the probe deployed in the ONU below the OLT, and vice versa. When the ICMP request sent by any probe does not respond within a fixed time, the second task in the network layer dial testing task is started, and traceroute commands are respectively sent to the probes of other ONUs deployed under the same OLT to judge which section of the route of the network channel has a problem.
(2) Test scene of internal network of public network
The probe deployed in the front-end processor can periodically initiate network layer dial testing to the probe deployed in the terminal below the probe, and vice versa. When the ICMP request sent by any probe does not respond within a fixed time, the second task in the network layer dial testing tasks is started, and traceroute commands are respectively initiated to the probes of other terminals deployed under the front-end processor to judge which route of the network channel has problems.
As shown in fig. 4, the terminal access network passive probe mapping diagram.
When the dial testing terminal initiates ICMP requests to network equipment, an application server and a user terminal, and when the dial testing object does not respond within the fixed request times, the dial testing agent preliminarily judges that the network is not accessible, and the next testing process is started. The dial testing agent initiates a traceroute command to the network equipment, the application server and the user terminal, the dial testing agent carries out ICMP request to each hop route, and when a certain route has no response, the dial testing agent prompts the IP of the route. The edge router is connected with the backbone router in an MP-BGP mode, and the backbone router is responsible for forwarding, so that the bandwidth of dial testing information is saved. Each backbone router dial testing terminal reports the routing information to the dial testing terminal connected with the management platform in a VPN mode, and the whole network routing information summarization is achieved.
The function of dialing the network layer to dial the test is to record the route path and hop count of the network layer test target and to query the route change of the test target. At present, a networking structure of a data communication network bears different service flows in an MPLS VPN mode, and a specific routing path can not be obtained through a dial testing path test in an MPLS label switching environment, but a global routing of the data communication network is complete IP routing switching and does not pass through any MPLS VPN, so that the specific routing path can be obtained through the dial testing global routing test. If the VPN and global IP addresses are tested simultaneously for the same target, the route path through global IP can be correlated to a path in the VPN address.
Fig. 5 is a schematic diagram of network self-healing switching based on an intelligent management and control system.
The power distribution service guide is started from a power distribution master station (client), and is respectively connected to a wireless network, an EPON network and an industrial Ethernet network downwards to further carry out service transmission. Accessing CPE (wireless terminal access equipment) from a TD-LTE base station (LTE core network) in a wireless mode, then accessing a HUB (HUB) and finally entering a DTU (server end); after receiving the information of the power distribution master station, the EPON goes from the OLT to the ONU, then enters the HUB and finally enters the DTU. The top layer is accessed with an intelligent management and control system which can monitor all nodes in the whole network topology structure, supervise the conditions of the nodes and realize visualization of the whole network. The whole network can also be automatically controlled.
If any link of the EPON network is not communicated, the management and control system receives feedback sent by the probe, monitors the position of a fault, and then sends an instruction to the LTE core network to transmit the service in a wireless mode; similarly, when any wireless link monitored by the control system fails, an instruction is sent to the EPON, so that services can be transmitted from the EPON, and the conditions of the industrial Ethernet are also similar. Therefore, the self-healing capability of the intelligent management and control system network is greatly improved.
