Fig. 4 is the flow chart of load-balancing method embodiment three of the present invention, and as shown in Figure 4, present embodiment provides a kind of load-balancing method, can specifically comprise the steps:
Because the interface of the F pattern of FCF equipment can't carry out mutual communication, then realize by existing standard, can't get access to the FCF information of all the FCF equipment in the same shared network.In order to get access to the FCF information of all the FCF equipment in the same shared network, be specially all FCF information among the same LAN herein, each FCF equipment is periodically issued the FCF information of self respectively by the business men customization type field in the FIP message in the present embodiment in network.Each FCF equipment is other FCF equipment periodic issues FIP message in same LAN respectively, in the business men customization type field of this FIP message, carry the FCF information of this FCF equipment self, thereby other FCF equipment among the same LAN that make can be collected the whole FCF information that exist among the same LAN by this message.
Fig. 5 as shown in Figure 5, supposes to be provided with in the network two FCoE terminals for the network architecture schematic diagram among the load-balancing method embodiment three of the present invention, and promptly H1 and H2 exist two FCF equipment, i.e. FCF A and FCF B among the same LAN.This step is the FCF information that FCF A and FCF B periodically issue self, and FCF A and FCF B all know and have FCF A, FCF B among the same LAN like this.
Step 402, FCoE terminal each FCF device broadcasts transmitting apparatus in consolidated network is found request message.
Still be example with Fig. 5, FCoE terminal H1 or H2 find request message with the FCF equipment transmitting apparatus of form in same LAN of broadcasting, and then FCF A and FCF B all can receive the device discovery request message that H1 or H2 send.
Receive the device discovery request message of FCoE terminal transmission when FCF equipment after,, obtain the forwarding priority of each FCF equipment respectively corresponding to this FCoE terminal according to the FCF information of each FCF equipment among the same LAN that collects.Particularly, this step can be specially: FCF equipment obtains the forwarding priority of each FCF equipment corresponding to the FCoE terminal respectively according to the ordinal relation of the number of the current FCoE terminal of supporting of each FCF equipment in the consolidated network of collecting; When the number of the current FCoE terminal of supporting of a plurality of FCF equipment equated, FCF equipment obtained the forwarding priority of a plurality of FCF equipment corresponding to the FCoE terminal respectively according to the size sequence relation of the node name sign of described a plurality of FCF equipment.In the present embodiment, the number of the current FCoE terminal of supporting of FCF equipment is few more, and then this FCF equipment is high more corresponding to the forwarding priority of FCoE terminal.When the number that has the current FCoE terminal of supporting of a plurality of FCF equipment equates, if only with the number of the current FCoE terminal of being supported of FCF equipment as the standard of weighing the forwarding priority height, the forwarding priority that this moment then occurs a plurality of FCF equipment is identical.Therefore, in this case, be used as weighing the forwarding priority standard just of FCF equipment in the present embodiment with the node name sign of FCF equipment; Even the node name sign of FCF equipment in a plurality of FCF equipment is more little, and then this FCF equipment is high more at the forwarding priority of these a plurality of FCF equipment, and the node name sign of FCF equipment herein can be the AC II code value of the node name of FCF equipment.
Still be example with Fig. 5, after FCF A received the device discovery request message that H1 sends, the FCF information according among the same LAN that collects calculated the forwarding priority of FCF A for H1, and correspondingly, FCF B also calculates the forwarding priority of FCF B for H1.Particularly, when calculating forwarding priority, the forwarding priority of the FCF equipment that the number of the current FCoE terminal of supporting is minimum is the highest; If the current number that has a FCoE terminal that a plurality of FCF equipment are supported is the most after a little while, then with the node name sign of FCF equipment as criterion, the FCF equipment that node name sign in a plurality of FCF equipment is minimum is as the highest FCF equipment of forwarding priority.For example, the number of supposing the current FCoE terminal of supporting of FCF A is 0, and the number of the current FCoE terminal of supporting of FCF B is 0, then this moment, the FCF A that obtains and FCF B equated with respect to the forwarding priority of H1, then continued node name according to FCF A and FCF B and identified and calculate the forwarding priority of FCF equipment for H1.The forwarding priority that is specially the minimum FCF equipment of node name sign herein is set to the highest, node name sign can be the AC II code value of the node name of FCF equipment, as the AC II code value of " A " AC II code value less than " B ", therefore, the forwarding priority that calculates FCF A is higher than the forwarding priority of FCF B.Same FCF B also needs the FCF information according to FCFA and FCF B, and it is lower for the forwarding priority of H1 to generate FCF B.
After FCF A receives the device discovery request message that H2 sends, go out the forwarding priority of each FCF equipment for H2 according to the FCF information calculations of FCF A and FCF B.For example, the number of the current FCoE terminal of supporting of FCF A is 1, and the number of the current FCoE terminal of supporting of FCF B is 0, according to the size order relation of the two, obtains FCF A and is lower than the forwarding priority of FCF B corresponding to H2 corresponding to the forwarding priority of H2.Similarly, FCF B is also higher for the forwarding priority of H2 according to the FCF information generation FCF B of FCF A and FCF B.
FCF equipment is found response message to FCoE terminal transmitting apparatus after calculating separately the forwarding priority corresponding to the FCoE terminal, carry forwarding priority in the device discovery response message.
The FCoE terminal selects the highest FCF equipment of forwarding priority as forwarding person according to each forwarding priority behind the forwarding priority that gets access to each FCF equipment correspondence, and the message of the follow-up transmission of this FCoE terminal is all transmitted by this FCF equipment.
Still be example with Fig. 5, FCF A obtains the forwarding priority of FCF A corresponding to H1 according to the FCF information of FCF A and FCF B, and then FCF A is just to the higher device discovery response message of H1 self forwarding priority of announcement.FCF B obtains the forwarding priority of FCF B corresponding to H1 according to the FCF information based on FCF A and FCF B, and then FCF B is just to the lower device discovery response message of H1 self forwarding priority of announcement.Like this, H1 just receives two device discovery response messages, and wherein the forwarding priority of FCF A is than the forwarding priority height of FCF B, so H1 will land to FCF A, the message that follow-up H1 of mailing to or H1 send just all can be with transmitting by FCF A.
FCF A obtains the forwarding priority of FCF A corresponding to H2 to the MAC Address of H2 based on the FCF information of FCF A and FCF B, and FCF A is just to the lower device discovery response message of H2 self forwarding priority of announcement.FCF B obtains the forwarding priority of FCF B corresponding to H2 according to the FCF information of FCF A and FCF B, and FCF B is just to the higher device discovery response message of H2 self forwarding priority of announcement.H2 just receives two device discovery response messages like this, and wherein the forwarding priority of FCF A is lower than the forwarding priority of FCFB, so H2 will land to FCF B, the message that follow-up H2 of mailing to or H2 send just all can be with transmitting by FCF B.
In the present embodiment, the MAC Address of different FCoE terminals is generated the forwarding priority based on the FCF information of all the FCF equipment among the same LAN, can guarantee that then all FCoE terminals land to different FCF equipment in a kind of average mode, on specific implementation, can adopt various modes, a simple realization use-case of lifting herein.When FCF equipment is received the device discovery request message of new FCoE terminal transmission, each FCF equipment all moves identical algorithm, obtain the forwarding person of the current support permission of all FCF equipment, from wherein electing the minimum FCF equipment of support terminal number as forwarding person as which FCoE terminal.If exist the minimum FCF equipment of the number of terminals of a plurality of supports as forwarding person, a FCF equipment then choosing the name identification minimum is as forwarding person.With Fig. 5 is example, when FCF A receives the device discovery request message of H1, know that at FCF A FCF A and FCF B are current all not as the forwarding person of terminal, so FCF A just selects the forwarding person of the less FCF A of title as H1 from FCF A and FCF B; Similarly, when FCF B receives the device discovery request message of H1, know that at FCFB FCF A and FCF B are current all not as the forwarding person of terminal, so FCF B just selects the forwarding person of the less FCF A of title as H1 from FCF A and FCF B.When FCF A received the device discovery request message of H2, FCF A was known FCF A as the forwarding person of H1, and FCF B is current also not as the forwarding person of terminal, so FCF A just selects the forwarding person of FCF B as H2 from FCF A and FCF B; Similarly, when FCF B received the device discovery request message of H2, FCF B was known FCF A as the forwarding person of H1, and FCF B is current also not as the forwarding person of terminal, so FCF B just selects the forwarding person of FCF B as H2 from FCF A and FCF B.
Further, in the present embodiment, when increasing a FCF equipment newly in the shared network, should also issue the FCF information of self by newly-increased FCF equipment by FIP message periodicity other FCF equipment in network, original FCF equipment can upgrade self FCF information in this moment network, i.e. FCF information in the consolidated network of collecting according to the FCF information updating FCF equipment self of newly-increased FCF equipment.At this moment, for the FCoE terminal of having landed, then still keep existing forwarding state, to prevent the phenomenon that stops.
When removing a FCF equipment in shared network, other FCF equipment in this shared network need remove the overtime FCF information of upgrading the shared network of self of FCF facility information because of this.For other FCF equipment in the consolidated network, if in default release cycle, do not receive the FCF information of a FCF equipment issue, show that then this FCF equipment is removed, then the FCF information of this FCF equipment of deletion in the FCF information of other FCF equipment from the consolidated network that self collects.For the FCoE terminal, if do not receive the device discovery response message that any one FCF equipment sends in the default time interval, then the FCF of each in network device broadcasts transmitting apparatus is found request message again.
Present embodiment provides a kind of load-balancing method, when FCF equipment receives the device discovery request message of FCoE terminal transmission, FCF information according to each FCF equipment of collecting, obtain the forwarding priority of each FCF equipment respectively corresponding to the FCoE terminal, each FCF equipment all sends to the FCoE terminal with self corresponding to the forwarding priority of FCoE terminal, and the FCoE terminal is selected the highest FCF equipment of forwarding priority to carry out message according to forwarding priority to transmit; Present embodiment has been realized the load balancing of FCF equipment, has avoided forwarding priority high FCF apparatus of load and flow excessive.And present embodiment need not FCoE terminal and FCF equipment are carried out manual configuration, just can dynamically carry out load balancing alternately based on basic protocol.
