Abstract
The invention discloses an equipment switching method, device and system based on a fiber communication network, which is used for solving the problems of low information interaction efficiency between a host end and a data center network and loss of transmitted information possibly caused by the equipment switching mode in the prior art. The method comprises the steps as follows: based on the first state information of current multiple detection objects and the second state information of the multiple detection objects in the normal state, an FCoE (Fiber Communication over Ethernet) exchanger judges whether a path from itself to the data center network fails; and if so the host end is notified to be switched to other FCoE exchangers. As the FCoE exchanger detects whether a path from itself to the data center network fails and notifies the host end to perform equipment switching in case of failure, the host end can be switched to other FCoE exchangers in time so as to perform information interaction with the data center network, thereby improving the information interaction efficiency between the host end and the data center network and avoiding the loss of transmitted information.
Description
Technical field
The present invention relates to the computer communication technology field, relate in particular to a kind of equipment switching method, Apparatus and system based on Networks of Fiber Communications.
Background technology
Based on Ethernet optical-fibre channel (Fibre Channel over Ethernet, FCoE) in the Networks of Fiber Communications of technology, host side is carried out information interaction by the FCoE switch and the data center network that connect, and wherein the FCoE switch is used for transmitting data between host side and data center network.
Carry out the reliability of information interaction in order to improve host side and data center network, host side links to each other with at least two FCoE switches usually, and carries out information interaction by these at least two the highest FCoE switch and data center network of FCoE switch medium priority.When detecting the highest FCoE switch of this priority, host side breaks down, when perhaps the circuit between the FCoE switch that this host side and this priority are the highest breaks down, switch to other FCoE switches, also promptly in these at least two FCoE switches except this priority in other FCoE switches the highest FCoE switch, reselect a FCoE switch that priority is the highest, and carry out information interaction by FCoE switch and the data center network reselected, shown in Figure 1A.
Figure 1A is based on the optical fiber communication network structure schematic diagram of FCoE technology in the prior art, in the network configuration shown in Figure 1A, ENode equipment H1 as host side strengthens Ethernet (Converged Enhanced Ethernet by polymerization, CEE), link to each other with B with the FCoE switch A, also by the CEE network, link to each other with B with the FCoE switch A as the ENode equipment H2 of host side, and the FCoE switch A all links to each other with data center network with B.Wherein, all preserved FCoE switch A corresponding priorities among H1 and the H2, and FCoE switch b corresponding priorities.When H1 will carry out information interaction with data center network, in FCoE switch A that connects and FCoE switch b, select the highest equipment of corresponding priorities, suppose that FCoE switch A corresponding priorities is higher than FCoE switch b corresponding priorities, then H1 selects the FCoE switch A, and be connected to data center network by the FCoE switch A, carry out information interaction with data center network.Switch A breaks down if H1 detects FCoE, when perhaps detecting circuit between H1 and the FCoE switch A and breaking down, then switches to the FCoE switch b, carries out information interaction by FCoE switch b and data center network.
But, in Figure 1A, if the FCoE switch A does not break down, circuit between H1 and the FCoE switch A does not break down yet, and the circuit between FCoE switch A and the data center network breaks down, and then H1 still can not carry out information interaction by the FCoE switch A and the data center network that connect.And since H1 this moment do not detect the FCoE switch A and break down, the circuit that does not also detect between H1 and the FCoE switch A breaks down, therefore remove non-artificial control H1 and switch to the FCoE switch b, otherwise H1 can not automatically switch to the FCoE switch b, still carry out information interaction by FCoE switch A and data center network, this will cause H1 wait for always circuit between FCoE switch A and the data center network recover normal after, could carry out normal information interaction with data center network, the efficient that makes host side and data center network carry out information interaction reduces, and may cause losing of the information of transmitting.
Figure 1B is based on the another kind of optical fiber communication network structure schematic diagram of FCoE technology in the prior art, shown in Figure 1B, in Figure 1B, host side H3 links to each other with D with FCoE switch C by the CEE network with H4, FCoE switch C and FCoE switch D are connected to target device S1 and S2 in the data center network by intermediate equipment 1 and intermediate equipment 2 respectively, suppose that the priority of FCoE switch C is higher than the priority of FCoE switch D, then H3 and H4 all carry out information interaction by FCoE switch C and data center network.At H3, when H3 will carry out information interaction with the target device S2 in the data center network, detailed process is, H3 is based on being connected with intermediate equipment 2 with being connected of being connected of FCoE switch C, FCoE switch C and intermediate equipment 1, intermediate equipment 1, and being connected of the target device S2 in intermediate equipment 2 and the data center network, carry out alternately with target device S2.Similar with Figure 1A, C does not break down if H3 detects the FCoE switch, the circuit that does not also detect between H3 and the FCoE switch C breaks down, if but intermediate equipment 1 or intermediate equipment 2 break down, perhaps, circuit between circuit between FCoE switch C and the intermediate equipment 1, intermediate equipment 1 and the intermediate equipment 2, and in the circuit between the target device S2 in intermediate equipment 2 and the data center network a certain or a few break down, and H3 just can not be undertaken by FCoE switch C and target device S2 alternately.Yet, because H3 this moment does not detect FCoE switch C and breaks down, the circuit that does not also detect between H3 and the FCoE switch C breaks down, therefore remove non-artificial control H3 and switch to FCoE switch D, otherwise H3 still selects FCoE switch C and target device S2 to carry out information interaction, then still need to wait for the intermediate equipment 1 and 2 between FCoE switch C and the data center network, and with intermediate equipment 1, after circuit between intermediate equipment 2 and the target device S2 recovers normally, could carry out normal information interaction with target device S2, the efficient that causes host side and data center network to carry out information interaction reduces, and may cause losing of the information of transmitting.

Embodiment
The embodiment of the invention provides a kind of equipment switching method based on Networks of Fiber Communications, Apparatus and system, this method FCoE switch is according to first state information of several detected objects that extract, and second state information of these several detected objects under normal condition of setting, judge whether self breaks down to the path of data center network, when breaking down, each host side that notice links to each other with self switches to other FCoE switches and data center network is carried out information interaction.Because whether the FCoE switch detects and self breaks down to the path of data center network in the embodiment of the invention, and the notice host side switches to other FCoE switches and data center network is carried out information interaction when breaking down, therefore host side can switch to other FCoE switches timely, improve host side and data center network and carried out the efficient of information interaction, and avoided losing of transmission information.
Below in conjunction with Figure of description, the embodiment of the invention is described in detail.
The process that the equipment based on Networks of Fiber Communications that Fig. 2 provides for the embodiment of the invention switches specifically may further comprise the steps:
S201: a FCoE switch extracts the first corresponding respectively state information of current these several detected objects according to several detected objects of setting.
In embodiments of the present invention, self whether break down, detect when self whether breaking down, can detect according to the first current state information of setting of several detected objects to the path of data center network by FCoE switch detection.Wherein, these several detected objects can be set as required.Concrete, these several detected objects comprise: each intermediate equipment of FCoE switch process in the path of data center network, circuit between the one FCoE switch and the intermediate equipment that is connected, circuit between each intermediate equipment, in the circuit between data center network and the intermediate equipment that is connected one or more, certainly, can also set other detected objects as required.
For example, if the network configuration of employing shown in Figure 1A, owing to do not have intermediate equipment, so these several detected objects can be the circuit between FCoE switch and the data center network.If adopt the network configuration shown in Figure 1B, shown in Figure 1B, suppose that FCoE switch C is a FCoE switch, when these several detected objects are each intermediate equipment of FCoE switch process in the path of data center network, these several detected objects are intermediate equipment 1 and the intermediate equipment 2 among Figure 1B, also promptly detect intermediate equipment 1 and whether intermediate equipment 2 breaks down.When these several detected objects be a FCoE switch with the intermediate equipment that is connected between circuit the time, these several detected objects are FCoE switch C among Figure 1B and the circuit between the intermediate equipment 1.When these several detected objects were circuit between each intermediate equipment, these several detected objects were intermediate equipment 1 among Figure 1B and the circuit between the intermediate equipment 2.When these several detected objects be data center network with the intermediate equipment that is connected between circuit the time, these several detected objects are the target device of data center network, and the circuit between the intermediate equipment.
S202: according to the first corresponding respectively state information of extracting of current these several detected objects, and these several detected objects of setting corresponding second state information under normal condition respectively, judge whether self breaks down to the path of data center network, if, then carry out step S203, otherwise carry out step S204.
In embodiments of the present invention, behind several detected objects that set to need detect, also to set a FCoE switch to the path of data center network in normal condition following time, second state information of these several detected objects.Thereby judge that the method that self whether breaks down to the path of data center network is specially, in the first corresponding respectively state information of several detected objects that extract, if determine to exist first state information of at least one detected object correspondence, different with this detected object of setting corresponding second state information under normal condition, then determine self to break down, otherwise determine that self is normal to the path of data center network to the path of data center network.
S203: each host side that notice links to each other with self switches to the 2nd FCoE switch and data center network is carried out information interaction.
Because a FCoE switch breaks down to the path of data center network, therefore may can not provide the function of transmitting data for host side, therefore notify host side to switch to the 2nd FCoE switch, also promptly switch to other FCoE switches and data center network and carry out information interaction.
S204: continue to transmit data.
If a FCoE switch is determined self not break down to the path of data center network, then host side can be proceeded information interaction by a FCoE switch and data center network.
In said process, self whether break down by the detection of FCoE switch to the path of data center network, and the notice host side switches to other FCoE switches and data center network is carried out information interaction when breaking down, therefore in prior art, need artificial main control system end-grain cutting to change to other FCoE switches, after perhaps host side need wait for always that the FCoE switch recovers normally to the path of data center network, could carry out normal information interactive method with data center network, the method host side that the embodiment of the invention provides can be when the FCoE switch breaks down, switch to other FCoE switches timely, improve host side and data center network and carried out the efficient of information interaction, and avoided losing of transmission information.
In embodiments of the present invention, for further when guaranteeing that host side can be carried out information interaction by FCoE switch and data center network, can also improve the efficient of information interaction as far as possible, make host side can switch the FCoE switch more flexibly, before step S203 shown in Figure 2, also promptly notify host side to switch to the 2nd FCoE switch and data center network is carried out before the information interaction, the one FCoE switch also will reduce the priority of self, and the precedence information after will reducing is notified to each host side that links to each other with self, and the precedence information of the FCoE switch that each host side that indication links to each other with self will be preserved is updated to the precedence information after the reduction.Wherein, the method that reduces the priority of self has a lot, for example directly reduces to the priority of self minimum.
In follow-up step, host side then can be according to the priority of the FCoE switch after upgrading, and the priority of each the 2nd FCoE switch that links to each other with self is carried out the equipment switching, concrete grammar is, host side is after the notice that switches to the 2nd FCoE switch that receives FCoE switch transmission, and switching to before the 2nd FCoE switch and data center network carry out information interaction, priority according to the FCoE switch after upgrading, and the priority of each the 2nd FCoE switch that links to each other with self, in respectively the 2nd FCoE switch of determining to link to each other, exist the priority of at least one the 2nd FCoE switch to be higher than the priority of the FCoE switch after the renewal with self.
In said process, because when host side is selected the FCoE switch, the highest FCoE switch of each FCoE switch medium priority that selection links to each other with this host side, if the priority of a FCoE switch is lower than the priority of certain the 2nd FCoE switch that links to each other with this host side after therefore upgrading, when then this host side is reselected the FCoE switch, just can not select this to reduce a FCoE switch of priority, and select the 2nd the highest FCoE switch of priority to switch, and carry out information interaction by the 2nd FCoE switch and data center network after switching.
And, owing to generally will transmit priority level initializing higher of the higher FCoE switch of the efficient of data, if the priority of a FCoE switch still is higher than the priority of any the 2nd FCoE switch that links to each other with this host side after therefore upgrading, to the path of data center network fault has appearred even a FCoE switch then is described, but the influence that the fault that occurs is carried out information interaction to host side by this paths and data center network is little, therefore this host side still can be passed through a FCoE switch-access data center network, and the efficient that a FCoE switch is transmitted data remains the highest, and also the efficient of promptly carrying out information interaction by a FCoE switch and data center network remains the highest.So the FCoE switch that this host side is reselected still is a FCoE switch, need not to switch to the 2nd relatively low FCoE switch of efficient that other transmit data, thereby when guaranteeing that host side can be carried out information interaction by FCoE switch and data center network, can also improve the efficient of information interaction as far as possible, improve the flexibility that host side is switched the FCoE switch.
In embodiments of the present invention, in order further to improve the flexibility that host side is switched the FCoE switch, the method that the one FCoE switch reduces the priority of self is specially, determine in these several detected objects, present located first state information and each different detected object of second state information under its normal condition, the priority of self is reduced, the value of reduction for the corresponding respectively reduction amplitude of each detected object of determining and value.Wherein, the reduction amplitude of each detected object correspondence can be set as required.
Preferable, will be bigger to what set by the reduction amplitude of the bigger detected object correspondence of FCoE switch-access data center network influence, will be less to what set by the reduction amplitude of the less detected object correspondence of FCoE switch-access data center network influence.Since at a FCoE switch in the path of data center network, if certain detected object is shorter to the length in the path of a FCoE switch, then this detected object is bigger to the influence by a FCoE switch-access data center network, otherwise, then influence less, therefore, set in the embodiment of the invention each detected object respectively the method for corresponding reduction amplitude be specially, at each detected object, according to the length of this detected object to the path of a FCoE switch, set the reduction amplitude of this detected object correspondence, wherein, the reduction amplitude of this detected object correspondence of setting is inversely proportional to the length of this detected object to the path of a FCoE switch.Also be, this detected object is short more to the length in the path of a FCoE switch, the reduction amplitude of this detected object correspondence of setting is big more, and this detected object is long more to the length in the path of a FCoE switch, and the reduction amplitude of this detected object correspondence of setting is more little.
For example, when detected object that needs detect be a FCoE switch with the intermediate equipment that is connected between circuit the time, because a FCoE switch is shorter to the length in the path of a FCoE switch with the circuit between the intermediate equipment that is connected, if the line out of service between a FCoE switch and the intermediate equipment that is connected, make a FCoE switch can not be connected to data center network, then can not the visit data central site network by a FCoE switch, therefore the circuit between a FCoE switch and the intermediate equipment that is connected, bigger to the influence by a FCoE switch-access data center network, with the reduction amplitude of this detected object correspondence set bigger.Suppose that host side links to each other with the FCoE switch b with the FCoE switch A, the priority of FCoE switch A is 5, and the priority of FCoE switch b is 3, so this host side is carried out information interaction by FCoE switch A and data center network.When detected object be this FCoE switch A with the intermediate equipment that is connected between circuit the time, the reduction amplitude of this detected object correspondence can be made as 5, if detecting this FCoE switch A according to first state information of current this detected object breaks down to the path of data center network, then the priority with the FCoE switch A reduces by 5, priority after the reduction is 0, when host side is reselected the FCoE switch, then can select the FCoE switch b.
In addition, can also set the weight of each detected object correspondence, and reduce the priority of self according to the corresponding weight of the first current state information each detected object different with second state information under the normal condition.For example, the weight of setting detected object a correspondence is 50%, the weight of detected object b correspondence is 30%, the weight of detected object c correspondence is 20%, if each detected object that the first then current state information is different with second state information under the normal condition is detected object a and b, then determine the weight of detected object a correspondence and detected object b correspondence weight and value, promptly 70%, self priority is reduced by 70%.
In embodiments of the present invention, (FCoE Initialization Protocol FIP) carries out alternately, and the message that comprises among the concrete FIP is as shown in table 1 by the FCoE initializtion protocol for host side and FCoE switch.
