The function of Ethernet OAM can be divided into fault management and performance management, wherein, fault management is used for the detection of connectivity of network, be similar to BFD (Bidirectional Forwarding Detection, two-way forwarding detection), MPLS (Multi-protocolLabel Switching, multiprotocol label switching) testing tool such as OAM, fault management can be used for realizing that fast detecting and trigger protection switch, and realize the target of service disconnection less than 50ms (millisecond); Performance management mainly refers to the packet loss in the Network Transmission, time delay, the isoparametric measurement of shake; Performance management can be operator monitoring network ruuning situation is provided, and whether the transfer capability of confirming network meets the SLA (Service Level Agreement, service-level agreement) that signs with the user etc.
Referring to Fig. 1, the Ethernet OAM networking schematic diagram that provides for prior art.Wherein, MD (Maintenance Domain, maintenance field) refers to carry out the network of OAM, is generally the territory that interconnected a plurality of Ethernet switch is formed.A MD has a manager, by the relevant device in manager's unified management MD.A MD can be divided into a plurality of SI (ServiceInstance, Service Instance) again, the corresponding VLAN (Virtual Local Area Network, VLAN) of a general SI.A SI may be made up of a plurality of equipment, wherein, some ports of one kind equipment meet CE (Customer Edge, user network boundary device), the logic port that these ports and VLAN Tag (label) are combined into is called MEP (Maintenanceassociation End Point, Maintenance association End Point), other port of this kind equipment is used to realize the connection between MEP, the logic port that these other ports and VLAN Tag are combined into is called MIP (Maintenance Association InternalPoint, Maintenance association Intermediate Point), MEP, MIP is referred to as MP (Maintenance Association Point, the Maintenance Association node), all MEP among SI form MA (Maintenance Association, Maintenance Association).
The interior subnetwork of MD may be safeguarded that promptly MD may be nested, is nested among the MD X as the MD Y among Fig. 1 by another manager.MD Level (rank) the information representation priority of messages of in the OAM message, carrying, can be used for handling the problem that different levels OAM passes through, the OAM message that priority is low can not pass through the high MD of priority, and the high OAM message of priority can pass through the low MD of priority, when the priority of OAM priority of messages and MD equates, judge whether this OAM message is the message that this MD need terminate, if, this OAM message terminates, otherwise abandon this OAM message, the OAM message can be controlled in this way in the territory of qualification and propagate.
Prior art provides a kind of Ethernet method of detection of connectivity end to end, and this detection of connectivity is carried out between all MEP in a MA, and each MEP is provided with a sign ID, and note is made MEP-ID, and this MEP-ID requires unique in same MA.Referring to Fig. 2, networking schematic diagram for the Ethernet detection of connectivity, wherein, Ethernet is divided into two territories, be respectively MD of operator and user MD, for example, among Fig. 2, CE1, CE2, CE3, CE4, MEP on CE5 and the CE6 equipment constitutes a MA1, MEP on CE7 and the CE8 equipment constitutes a MA2, and wherein, the CE equipment in each MA passes through MEP regularly to PE (Provider Edge, service provider edge router) equipment sends CCM (Continuity Check Message, detection of connectivity message) message, thereby the connectedness of detection and miscellaneous equipment be not when receiving the CCM message of certain equipment in the designated period, think that then the inner somewhere of this MA breaks down, pass through loopback detection then, link tracing detects and carries out fault location.
The inventor finds that in realizing process of the present invention there is following problem in above-mentioned method for detecting connectivity:
When the user sends a large amount of CCM messages and carries out detection of connectivity, the bigger bandwidth of operator will be taken, for example: with the sense cycle is that 10ms calculates, each CCM message does not comprise TLV (Type Length Value, type) is 103 bytes, the bandwidth that takies is 82.4Kbps (1000/10*103*8), can support 8K node to detect simultaneously in each MA, and at this moment user must take the bandwidth (8K*82.4K) of 660M; If the user adopts the sense cycle of 3.3ms, the bandwidth that takies operator will be more.When the multi-user detects simultaneously, can take the bigger bandwidth of operator, influence other business of operator, simultaneously, when if malicious user adopts the CCM message that operator is attacked, will consume the bandwidth of operator, bring safety problem can for the network of operator.
