Description
Technical field
The present invention relates to a kind of network for formance measuring method, especially a kind of IP based network is at two layers of mesh tubular construction and the cross-domain method of initiatively initiating network performance measurement.
Background technology
Network performance is meant when a certain paths of packet in network is transmitted, and calculates the performance parameter value in this path that obtains, as propagation delay time, delay variation and packet loss.According to the difference in first, second node (or tested path), network performance comprises unilateral network performance and loopback network performance.First, second node in the tested path of unidirectional finger is different nodes, and packet ends at Section Point after sending from first node.The loopback network performance refers to that first, second node is same node, after packet sends from first node, behind a certain loopback node of appointment, is sent and end at back to first node in the arrival network; At this moment, the loopback node in the network also needs to specify.The network that carries out network performance measurement mainly is meant IP network, also can comprise other networks.
In network performance measurement, can be divided into dual mode, Active Networks performance measurement and passive network performance measurement.The Active Networks performance measurement is meant that the packet that is used to measure is produced specially, is different with user data package.After measuring termination, just there are not these measurement data bags in the network.In the passive network performance measurement, do not have the special measurement data bag that produces in the network, all metrical informations all obtain from user data package.
At present, all adopt the Active Performance method of measurement about network performance measurement, promptly in network, inject the packet that is specifically designed to measurement at the first node of measuring, after Section Point is received this measurement bag, from this measurement bag, extract relevant information, go out performance parameter such as time delay, test shake and the packet loss of packet when this inter-two-point path transmits according to these information calculations at last.The conveying function parameter of these network inter-two-point paths abbreviates network performance parameter usually as.
It below is the introduction of various device related in the network performance measurement.Network element (NE) is the elementary cell in the network, is used to transmit packet, is exactly a NE as a router.Operation maintenance center (OMC) and webmaster control system (NMS) all are network management units.Several NE form a subnet, and each subnet is managed by an OMC; Several subnets are formed a big net, and each big net has a NMS generally speaking.Network diagram is that a NMS manages several OMC in this network as shown in Figure 1.
The technical scheme that existing network performance measurement is relevant has following several:
Technical scheme one: IETF IPPM working group has formulated relevant agreement of IP network performance measurement and flow process, and its functional entity as shown in Figure 2.Wherein be divided into 5 functional entitys: server (Server), client's control end (Control-Client), client read end (Fetch-Client), session transmitting terminal (Session-Sender) and session receiving terminal (Session-Receiver).Wherein, Session-Sender and Session-Receiver are starting point and the terminal points of measuring, in network corresponding to network equipments such as RNC, MGW or routers; Control-Client is responsible for initiating control command; Fetch-Client is responsible for collecting measurement result; Server realizes one or more measurements being managed control of measuring and result's collection.IPPM has defined OWAMP (One Way ActiveMeasurement Protocol) agreement at present, and this agreement is divided into OWAMP-Control and OWAMP-Test again.OWAMP-Control is used to realize the transmission of measurement configuration information and measurement result between Control-Client/Fetch-Client and the Server; OWAMP-Test is between Session-Sender and the Session-Receiver, the agreement that the measurement data bag should be followed.Proposed in this technical scheme to measure employed agreement, do not related to and how to initiate between NMS in the network, OMC and the NE to measure, how to have collected measurement result.
Technical scheme two: when carrying out network performance measurement initiatively in atm network, flow process is: OMC (or NMS) sends measurement configuration information to first and second NE that measure; The one NE sends to the 2nd NE and measures bag; When measuring end, the 2nd NE calculates corresponding network performance measurement parameter according to receiving the information of measuring in the bag.A kind of measuring command send mode that this scheme adopts when initiatively measuring usually, simultaneously carry out information interaction by OMC or NMS with first, second NE, flow process is comparatively simple, do not consider the various complex network situations under the actual conditions, as the three-decker that NMS, OMC and NE formed, stride the measurement problem of different management domains etc.; And at be the three-layer network structure.That is, in atm network, the network enabled performance measurement.Scheme is at present: send measurement configuration information by OMC to NE, and trigger and measure.Can not transmit measurement configuration information between the NE; Except that measuring cell, cell alternately not between the NE.Under the three-decker that this scheme does not refer explicitly to be made up of NMS, OMC and NE, how to realize network performance measurement.And because atm network and IP network performance measurement is machine-processed incomplete same, so the implementation of IP network performance test is also different.In addition, under the situation of not communicating by letter between the OMC, this technical scheme is difficult to realize crossing over the network performance measurement of OMC.
Technical scheme three: in 3GPP (being responsible to define the International Standards Organization of 3G communication standard), only formulate the standard of interface between NMS and the OMC, perhaps the interface between NMS and the NE at present; Between the OMC, and the interface between OMC and the network element adopts the implementation of each producer inside.This technical scheme does not realize the measurement of network performance, has just stipulated the standard of interface between some equipment.And in the standard that 3GPP formulates, do not have at present to realize to realizing the definition of network performance measurement function.
Therefore, up to the present, after also consideration is not having OMC equipment in network (especially IP network) performance measurement, the network performance measurement between NMS and NE double-layer structure, and the network for formance measuring method when NE belongs to different N MS.
Summary of the invention
