Description
Technical field
The present invention relates to the communications field, in particular to system of selection of a kind of activation condensate and device.
Background technology
LACP (Link Aggregation Control Protocol, link aggregate control protocol) two or more physical links can be invented a logical links, to MAC (Media Access Control, the medium access control) client Client presents single, standard IEEE 802.3 interfaces, present to upper layer application pellucidly, the bandwidth of logical links be active link bandwidth and.The physical port that is tied to same logical links should possess identical ethernet link layer characteristic, for example port speed, duplex, port status etc., the benefit of doing like this is, when a certain physical link wherein presents unavailable down state, this physical link loaded service can be passed through other physical link load sharings, as long as the physical link that exists some to work in the logical links just can not have influence on upper-layer service.That is, adopt the LACP technology can increase the bandwidth of link, realized other redundancy backup of link level.
The link aggregate control protocol of standard comprises and operates in five protocol state machines with specific function that connect each other on the physical port.
Existing LACP agreement comprises following state machine, and its function and correlation are described below:
Receive (RX) state machine (Receive Machine): this state machine is resolved LACPDU (the Link Aggregation Control Protocol Data Unit that receives from Partner (opposite end), the link aggregate control protocol data cell), record information and the overtime use that is provided with according to LACP wherein is short overtime or longly overtimely make it overtime, the information that the RX state machine evaluation is come from Partner, determine whether Actor (local terminal) and opposite end have agreed that the protocol information that exchanges is used for port and other port trunking to a certain extent or becomes separate port, otherwise the RX state machine produces NTT to send new protocol information to Partner, if the protocol information of Partner is overtime, the parameter value that the RX state machine is provided with acquiescence uses for other state machine.
Cycle transmit status machine (Periodic Transmission Machine): the aggregation scheme of determining Actor and Partner thereof, and whether exchange LACPDU (if any end or two ends all are configured to Active, regularly LACPDU take place alternately) periodically in order to keep polymerization.
Select logic state machine (Selection Logic Machine): be responsible for selecting the Aggregator (condensate) consistent, and which Aggregator is in state of activation among a plurality of Aggregator that make a strategic decision with this port attribute.
MUX state machine (Mux Machine): be responsible for opening or closing according to the requirement of current protocol information collecting and distributing with port.
Send (TX) state machine (Transmit Machine): handle under the requirement of other state machine or based on the transmission of regular LACPDU.
Have active link in LAG (Link Aggregation Group, aggregation group), aggregation port newspaper agreement can be used up, and upper-layer service just can normally be used this aggregation port.If professional have requirement to active link number in the aggregation port, promptly when aggregation port active link number during more than or equal to a certain value, aggregation port could output protocol up, professional this aggregation port of normally use; When aggregation port active link number during less than a certain value, even have active link in this aggregation group, aggregation port is also wanted output protocol down, and Here it is, and common LACP least member counts function.
As shown in Figure 1, three physical link butt joints of device A and equipment B, the LACP protocol interaction of employing standard.Article three, physical link consults successfully to be state of activation, two ends aggregation port newspaper agreement up; It is 3 that LAG_A configuration least member counts MiniMem_A, it is 3 that LAG_B configuration least member counts MiniMem_B, the configuration of two ends LAG equity least member number, when certain bar physical link fault wherein, when link was transitted towards unactivated state, LAG_A activated the Member Link number less than MiniMem_A (current configuration is 3), LAG_A newspaper aggregation port agreement down, in like manner the LAG_B aggregation port is reported agreement down, at this moment two ends aggregation port protocol status unanimity.
Further, as shown in Figure 2, the not reciprocity least member's number configuration of LAG_A and LAG_B is configured to 3 as MiniMem_A, and MiniMem_B is configured to 2, when certain bar physics wherein is unactivated state, count function according to existing least member, the LAG_A end can be reported aggregation port agreement down, and LAG_B end aggregation port agreement remains up, it is inconsistent to cause docking two ends aggregation port protocol status like this, uses the business transmitting-receiving of aggregation port to have unusual.
This shows, existing LAG least member counts in the function, when the active link number is counted less than the least member among the LAG, just aggregation port is reported agreement down, do not influence the physical link normal negotiations, that is to say, aggregation port agreement down, still have active link among the LAG, just the active link number is less than least member's number.
As shown in Figure 3, current C E (Customer Edge, the client edge) end is selected and PE1 (Provider Edge, Provider Edge) butt joint link, CE holds minimum active link number to satisfy least member's number, aggregation port agreement up, and the PE1 end does not satisfy least member's number, aggregation port agreement down, the two ends aggregation port protocol status of LACP butt joint is inconsistent.
So, usually least member's number of each vendor equipment requirement two ends LAG is the equity configuration, that is to say, if LAG_CE has disposed the least member and has counted MiniMember, then must LAG_PE1 will dispose least member's number is MiniMember, based on Fig. 3 networking, requiring LAG_PE2 also will dispose least member's number simultaneously is MiniMember.
This shows that existing LACP least member counts function very big defective, butt joint two ends aggregation port protocol status is inconsistent, and the upper-layer service of using aggregation port occurs unusual; Configurable limit also is very unfriendly to the user, has limited different vendor's equipment interconnection, and arrangement abnormalities in time finds to need to lean on network management personnel's maturity.

Step S506 obtains current LAG and activates condensate (Active state);
Step S508 obtains activating condensate associated ports number (but active link number);
Step S510 obtains current LAG least member number (needing the active link number);
Step S512, whether current activation condensate satisfies optimum condensate condition, if, execution in step S536, if not, execution in step S514;
Step S514, current activation condensate does not satisfy optimum condensate condition, and logic is selected optimum condensate again;
Step S516 judges whether to exist optimum condensate condition, if, execution in step S530, if not, execution in step S518 is to step S528;
There is not optimum condensate in step S518, and putting former activation condensate is unactivated state (Inactive state);
Step S520, there is not the condensate that satisfies condition in the prompting user;
Step S522, putting current activation condensate associated ports is non-selected state (Selected=FALSE), putting port is the OUT_OF_SYNC state;
Step S524, current activation condensate associated ports is transitted towards unactivated state, aggregation port newspaper agreement down;
Step S526, port send and comprise the message of OUT_OF_SYNC to the opposite end;
Step S528 receives the message that comprises the OUT_OF_SYNC state, and the opposite end is activated port and is transitted towards unactivated state, same aggregation port newspaper agreement down;
Step S530, if there is optimum condensate among the step S516, then putting former activation condensate is unactivated state (Inactive state), arrives step S528 with step S522;
Step S532 activates the new optimum condensate that satisfies condition;
Step S534, putting new activation condensate associated ports is selected state (Selected=TRUE);
Step S536 finishes.
Based on of the expansion of above step, make the LAG that does not meet least member's number not have the activation physical link, aggregation port newspaper protocol status down to LACP agreement selection logic state machine.
Two ends in the LACP butt joint, wherein there is not the condensate that satisfies least member's number in an end LAG, and then there is not the activation condensate in this LAG, and is mutual by Link Aggregation Control Protocol Data Unit, the opposite end physical link also can be transitted towards unactivated state, thereby guarantees butt joint two ends aggregation port protocol status unanimity.
In sum, the embodiment of the invention is selected logic state machine by expansion LACP agreement on the basis of following LACP standard agreement state machine, and it is inconsistent unusual to have eliminated the two ends aggregation port protocol status that not reciprocity least member's number configuration causes effectively.
