Description
Technical field
The present invention relates to communication technical field, particularly a kind of network management system and communication means thereof.
Background technology
Development along with computer networking technology, the rapid expansion of the scale of computer network and range of application, the task that network is born is more and more heavy, therefore a series of special NMPs have appearred, by network management, make great efforts to improve utilance, performance, service quality and the fail safe of the network equipment.
At present, mainly contain following several NMP: the ITU-T of telecommunication standardization sector of International Telecommunications Union (the former telegram telephone counseling CCITT of the committee) proposed specially at telecommunication network management telecommunication management network (Telecommunications Management Network, TMN); International Standards Organization (International Organization for Standardization, ISO) also for network management worked out CMIP (Common Management Information Protocol, CMIP); International Internet organizes then and has worked out Simple Network Management Protocol (SNMP) for network management.
Above-mentioned several NMP has different separately starting points, and wherein: TMN designs at telecommunication network management; CMIP be for the inventionthe open systems interconnection reference model (Open SystemInterconnection, 7 layer models OSI) design; SNMP then is based on the NMP of TCP/IP net, is from early stage simple gateway monitoring protocol (Simple Gateway ManagementProtocol, SGMP) development.In these standards, the function of CMIP is the most powerful, but it realizes that difficulty is also maximum, and this has just hindered its application, and the product of therefore present support CMIP seldom; SNMP is then because therefore it simple and easy to operate be widely used and the standard on having come true.
As shown in Figure 1, be the structural representation of the network management architecture of using snmp protocol.This architecture mainly comprises: and the management information bank of managing process (Manager) unit, administration agent (Agent) unit, Managed Object (Managed Object) and description Managed Object state (ManagementInformation Base, MIB).Wherein: the managing process unit is the control centre of whole network management system, and it is monitored and control the various device in the network, facility and resource by each administration agent unit, and finishes various management functions.In addition, the managing process unit is furnished with man-machine interface usually, and the information and the data of the Managed Object collected are filed, analyzed and handle.The managing process unit operates on the management server, and the administration agent unit operates on the network equipment.
Communicate by the snmp management agreement between managing process unit and the administration agent unit.In snmp protocol, defined 4 class bookkeeping: Get operation; Get Next operation; The Set operation; Trap (trap) operation.Managing process unit by using Get and Get Next operate the information of extracting each management information bank, and then obtain the current comprehensive state information of network.Where necessary, the managing process unit can be by indirect some information that is provided with or revises in the management information bank of Set operation, to reach the purpose of control.When serious anomalous event took place network, active was just operated to managing process unit reporting event by Trap in the administration agent unit, thereby had improved the aging performance of network management greatly.
As shown in Figure 2, be the SNMP message information form schematic diagram of various version.The SNMP message information comprises: version number, community name and protocol Data Unit.Wherein: Version is the version number of snmp protocol, and managing process unit and administration agent unit must use the snmp protocol of identical version; Community is a community name, is used for before managing process unit access administration agent unit the managing process unit being authenticated; PDU is a protocol Data Unit, wherein comprises concrete message content.
SNMP is a kind of application protocol, is encapsulated in the User Datagram Protoco (UDP) (UDP).Because udp protocol not be used between client and the server and connects, and do not have mechanism such as overtime repeating transmission before datagram, so transmission speed is very fast.But, udp protocol is the transition layer protocol of a simple datagram-oriented, the datagram of just application program being passed to the IP layer sends, but can not guarantee that these datagrams can arrive the destination, and SNMP is encapsulated among the UDP, whether receive the alarm Trap information of the network equipment so can't confirm management server, and when the network communication between the management server and the network equipment was broken down, the network equipment can not obtain returning of " alarm sending failure " yet.In the network management system of reality, losing of significant alarm information can bring serious negative effect to the stability and the maintainability of system's operation.
