Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

Fig. 1 is the schematic diagram of network link, and with reference to Fig. 1, wherein A ~ I indicates each network node in network, and solid arrow indicates the Business Stream and the direction that flow through this network.Referring to Fig. 1, the concept that the embodiment of the present invention is relevant is described.

Concept: hop-by-hop (HOP)

HOP is exactly that service message is sent to link that next Observable website (or site groups) may experience and the set that interface is formed from an Observable website (or site groups) on path.Such as Fig. 1 interior joint A is to node D.Target service flow to into website (namely target logic port TLP(Target Logical Port) hereinafter) or site groups (i.e. TLP Group) be called entrance TLP group (Ingress TLP Group), the website (TLP) that target service stream flows out or site groups (TLP Group) are called outlet TLP group (Egress TLP Group), therefore one closed (Hop) is represented by a tuple (Ingress TLP Group, Egress TLP Group).

Concept: closed HOP and non-closed HOP

As shown in Figure 1, inside compound path, the feature of Hop ({ A}, { D}) be flow on outlet TLP{D} except from its entrance TLP{A}, also have the flow from other nodes; The feature of Hop ({ F}, { G, H}) is that the flow of entrance TLP{F} does not all go to outlet TLP{G, H}.This two class HOP is non-closed Hop, obviously cannot based on performance datas such as the packet loss of non-closed Hop computing service stream, time delays.

Relative non-closed Hop is exactly closed Hop(Closed Hop, abbreviation CH), CH is exactly all flows sent from the entrance TLP group of this Hop, all goes to the outlet TLP group of this Hop.Such as, { (A, B), D } in Fig. 1 three node TLP just can form a CH (closed Hop).

Concept: atom closes HOP(Atom Closed Hop, abbreviation ACH)

Less closed HOP cannot be partitioned into again be further referred to as atom and close HOP in given pahtfinder hard, namely the minimum measuring object in Examples below, at Internet protocol (Internet Protocol, be called for short: IP) carry out pointwise performance measurement in network pahtfinder hard, obviously the performance measurements based on ACH must meet the exact position navigating to property abnormality, and the ACH therefore under IP network pahtfinder hard is the minimum performance measuring object in IP network pahtfinder hard.

Before the computational methods providing minimum performance measuring object, according to the definition of ACH, (otherwise comprise multiple ACH that this TLP is entrance TLP will inevitably there is inclusion relation, this and ACH define contradiction) can only be there is at most in an ACH in the TLP that can derive a service path as the entrance TLP group membership of ACH; A same TLP can only occur at most as the outlet TLP group membership of ACH in an ACH.

Fig. 2 is the flow chart of the acquisition methods embodiment one of the minimum measuring object of network performance fault of the present invention, it should be noted that, the executive agent of the present embodiment is the acquisition device of the minimum measuring object of network performance fault, and as shown in Figure 2, the method can comprise:

TLP) and outlet TLP step 100, obtain the link set of network all links, link set comprises the entrance target logic port forming each link, and (Target Logical Port is called for short:.

Concrete, for a network, each the network element node in this network disposes TLP, and this TLP, as performance measurement execution point, for identifying that target service stream and execution performance are measured, such as, measures the packet loss of Business Stream, time delay etc.Further, when a Business Stream is transmitted by a link of network, the TLP that Business Stream enters this link is entrance TLP, and the TLP that Business Stream leaves this link is outlet TLP.In a network, owing to there is multiple network element node, therefore different links can be formed by different network element nodes.The entrance TLP that link set in step 100 comprises and outlet TLP, concrete can for uniquely indicating the identification information of this entrance TLP or outlet TLP.

Step 101, one by one extraction entrance TLP are as the forward transient node of minimum measuring object set.

Concrete, minimum measuring object is the most short chain road in whole network, and namely such as network element node A and adjacent down hop network element Node B form a most short chain road.And when the performance of a network breaks down, such as, packet loss or time delay have exceeded normal threshold value, often need further to determine that fault has appearred in which the network element node in specifically network, after determining concrete abort situation, could more effectively keep in repair.Now, the minimum measuring object in the present embodiment, namely can embody the meticulousst abort situation that can measure in a network.
