6 results about "Network management station" patented technology

The invention relates to a method for operating a network, in which at least two network devices are connected to each other via a data line and exchange data via the data line, each network device is fixedly distributed with an independent MAC address; furthermore, the network management station controls the configuration and / or operation of the network, in which a request is sent by the network management station to the network device by means of a language-independent data format in a multicast manner in order to query configuration parameters of the network device and / or to configure the requested network device by means of the language-independent data format.

A system includes a plurality of network access devices that are remotely distributed and coupled to at least one Internet-coupled, wide-area wireless network. Each of the plurality of network access devices persistently execute respective device management programs. The device management programs are operable to read and change local device status and maintain respective persistent network socket connections. The system includes an Internet-coupled data center with one or more servers that operate a plurality of Simple Network Management Protocol (SNMP) agent programs. Each of the SNMP agent programs communicate with a respective one of the device management programs via the persistent network socket connections. The SNMP agent programs provide an SNMP interface at the data center. A network management station manages the respective network access devices via the respective SNMP interfaces, the respective device management programs, and the respective persistent network socket connections.

The invention discloses an FDMA satellite communication network multi-stage management system based on a hybrid management channel. The FDMA satellite communication network multi-stage management system comprises a first-stage network management center, a plurality of second-stage network management centers and a plurality of third-stage network management stations belonging to the second-stage network management centers, a ground private network is established between the primary network management center and the secondary network management center; a TDMA satellite communication network network is established between each second-level network management center and a plurality of subordinate third-level network management stations; the third-level network management station is used for managing equipment in the earth station; the secondary network management center is used for centrally managing the state and parameters of each station device in the area; and the primary network management center is used for managing the whole satellite communication network. According to the system, a three-level management architecture adopting a centralized management mode is designed, and equipment management and resource management are completed through mutual cooperation; a ground special line and a TDMA satellite communication network are combined to manage a channel, so that the limitation of a service communication satellite is eliminated, and the defect that a reverse ALOHA is easy to conflict and collide is overcome; and the flexibility and the expansibility of multi-satellite networking are improved.

The application discloses a network expansion management method and device based on SNMPv3. The method comprises: constructing, at the proxy end, an aggregated view configuration management information base including an aggregated view configuration table and an aggregated view OID table, and a data subscription management information base including a subscription table; sending, by the network management station, a first and a second SetRequest PDU to the proxy end; creating, based on the first SetRequest PDU, an aggregated view in the aggregated view configuration table, assigning a unique name and ID to the aggregated view, and configuring, in the aggregated view OID table, a mapping relationship between each object identifier OID from different MIB trees and each aggregated view ID; creating, based on the second SetRequest PDU, a subscription entry in the subscription table, each subscription entry specifying a target aggregated view, a trigger condition and a security parameter; monitoring, by the proxy end, the target aggregated view in the subscription entry, and obtaining a target object identifier OID corresponding to the ID when the trigger condition is met; constructing, by the proxy end, an InformRequest PDU, and sending, based on the security parameter, data corresponding to the target object identifier OID to the network management station; and updating, by the network management station, the data based on the InformRequest PDU and sending back an acknowledgement. The application can improve the efficiency, real-time performance and security of network management.

The invention relates to a method for planning, operating and optionally eliminating errors in a network topology of a network having network devices, which are connected to one another in accordance with the functionality of the network, characterized in that the network devices are connected to one another in a wired manner. The topology of the network is first planned by means of a suitable planning tool, and then the planned network is in line connection with the network devices thereof, the network devices are addressed one by one from a network management station, and an IP address is assigned to each network device according to the undefined identification feature of each network device. Thereafter, the network devices receive and store their configuration data and then perform a restart on each network device to activate the received and stored configuration.
