The flow chart that Fig. 4 is load-balancing method embodiment tri-of the present invention, as shown in Figure 4, the 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 be communicated by letter mutually, by existing standard implementation, can't get the FCF information of all FCF equipment in same shared network.In order to get the FCF information of all FCF equipment in same shared network, be specially all FCF information in same LAN herein, in the present embodiment, each FCF equipment, by the business men customization type field in the FIP message, is periodically issued the FCF information of self respectively in network.Each FCF equipment is respectively to other FCF equipment periodic issues FIP message in same LAN, carry the FCF information of this FCF equipment self in the business men customization type field of this FIP message, thereby make other FCF equipment in same LAN can collect by this message the whole FCF information that exist in same LAN.
Fig. 5 is the network architecture schematic diagram in load-balancing method embodiment tri-of the present invention, as shown in Figure 5, supposes in network to be provided with two FCoE terminals, and H1 and H2, exist two FCF equipment, i.e. FCF A and FCF B in 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 in same LAN and have FCF A, FCF B like this.
Step 402, the FCoE terminal is found request message to each FCF device broadcasts transmitting apparatus in consolidated network.
Still take Fig. 5 as example, and FCoE terminal H1 or H2 find request message with the form of broadcast to the FCF equipment transmitting apparatus in same LAN, and FCF A and FCF B all can receive the device discovery request message of H1 or H2 transmission.
After FCF equipment receives the device discovery request message of FCoE terminal transmission, according to the FCF information of each FCF equipment in the same LAN collected, obtain respectively the forwarding priority of each FCF equipment corresponding to this FCoE terminal.Particularly, this step can be specially: the ordinal relation of FCF equipment number of current supported FCoE terminal according to each FCF equipment in the consolidated network of collecting, obtain respectively the forwarding priority of each FCF equipment corresponding to the FCoE terminal; When the number of current the supported FCoE terminal of a plurality of FCF equipment equates, FCF equipment, according to the ordinal relation of the size of the node name sign of described a plurality of FCF equipment, obtains respectively the forwarding priority of a plurality of FCF equipment corresponding to the FCoE terminal.In the present embodiment, the number of the FCoE terminal that FCF equipment is current supported is fewer, and this FCF equipment is higher corresponding to the forwarding priority of FCoE terminal.When the number that has current the supported FCoE terminal of a plurality of FCF equipment equates, if only using the number of the current FCoE terminal of being supported of FCF equipment as the standard of weighing the forwarding priority height, now occur that the forwarding priority of 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 of FCF equipment in a plurality of FCF equipment sign is less, and this FCF equipment is higher 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 take Fig. 5 as example, and after FCF A receives the device discovery request message of H1 transmission, the FCF information according in the same LAN collected, calculate 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 current supported FCoE terminal is minimum is the highest; While existing the number of the FCoE terminal that a plurality of FCF equipment supports minimum if current, using the node name sign of FCF equipment as criterion, node name in a plurality of FCF equipment is identified to the minimum FCF equipment FCF equipment the highest as forwarding priority.For example, the number of supposing the FCoE terminal that FCF A is current supported is 0, and the number of current the supported FCoE terminal of FCF B is 0, the FCF A now obtained and FCF B equate with respect to the forwarding priority of H1, continue to identify to calculate the forwarding priority of FCF equipment for H1 according to the node name of FCF A and FCF B.Being specially the forwarding priority that node name identifies minimum FCF equipment 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 " is less than the AC II code value of " B ", therefore, calculate the forwarding priority of the forwarding priority of FCF A higher than FCF B.Same FCF B also needs the FCF information according to FCFA and FCF B, generates FCF B lower for the forwarding priority of H1.
After FCF A receives the device discovery request message of H2 transmission, according to the FCF information of FCF A and FCF B, calculate the forwarding priority of each FCF equipment for H2.For example, the number of the FCoE terminal that FCF A is current supported is 1, and the number of current the supported FCoE terminal of FCF B is 0, according to the size order relation of the two, obtain FCF A corresponding to the forwarding priority of H2 lower than FCF B the forwarding priority corresponding to 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, after calculating separately the forwarding priority corresponding to the FCoE terminal, is found response message to FCoE terminal transmitting apparatus, in the device discovery response message, carries forwarding priority.
The FCoE terminal is after getting the forwarding priority that each FCF equipment is corresponding, and the FCF equipment the highest according to each forwarding priority selection forwarding priority is as forwarding person, and the message of the follow-up transmission of this FCoE terminal is all forwarded by this FCF equipment.
Still take Fig. 5 as example, and FCF A obtains the forwarding priority of FCF A corresponding to H1 according to the FCF information of FCF A and FCF B, and 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 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 higher than the forwarding priority of FCF B, so H1 will be logged in to FCF A, the message that the follow-up H1 of mailing to or H1 send just all can be with being forwarded by FCF A.
FCF A obtains the forwarding priority of FCF A corresponding to H2 to the FCF information of MAC Address based on FCF A and FCF B of H2, 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 be logged in to FCF B, the message that the follow-up H2 of mailing to or H2 send just all can be with being forwarded by FCF B.
In the present embodiment, FCF information to all FCF equipment of MAC Address based in same LAN of different FCoE terminals generates the forwarding priority, can guarantee that all FCoE terminals are logged in to different FCF equipment in a kind of average mode, can adopt various modes on specific implementation, simple act herein realizes use-case.When FCF equipment is received the device discovery request message of new FCoE terminal transmission, each FCF equipment all moves identical algorithm, obtain the current support of all FCF equipment and allow the forwarding person as which FCoE terminal, from wherein electing the minimum FCF equipment of support terminal number as forwarding person.If exist the minimum FCF equipment of the number of terminals of a plurality of supports as forwarding person, choose a FCF equipment of name identification minimum as forwarding person.Take Fig. 5 as example, when FCF A receives the device discovery request message of H1, FCF A know FCF A and FCF B current all not as the forwarding person of terminal, so FCF A just selects FCF A that title the is less forwarding person as H1 from FCF A and FCF B; Similarly, when FCF B receives the device discovery request message of H1, FCFB know FCF A and FCF B current all not as the forwarding person of terminal, so FCF B just selects FCF A that title the is less forwarding person as H1 from FCF A and FCF B.When FCF A receives the device discovery request message of H2, FCF A knows that FCF A is 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 receives the device discovery request message of H2, FCF B knows that FCF A is 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, while in shared network, increasing a FCF equipment newly, should also by FIP message periodicity, to other FCF equipment in network, issue the FCF information of self by newly-increased FCF equipment, now in network, original FCF equipment can upgrade self FCF information, the FCF information in the consolidated network of collecting according to the FCF information updating FCF equipment self of newly-increased FCF equipment.Now, for the FCoE terminal logged in, 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 to remove the overtime FCF information of upgrading the shared network of self of FCF facility information because of this.For other FCF equipment in consolidated network, if do not receive the FCF information of a FCF equipment issue in default release cycle, show that this FCF equipment is removed, delete the FCF information of this FCF equipment in the FCF information the consolidated network that other FCF equipment are collected from self.For the FCoE terminal, if do not receive the device discovery response message that any one FCF equipment sends within the default time interval, again to each FCF device broadcasts transmitting apparatus in network, find request message.
The 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 respectively the forwarding priority of each FCF equipment corresponding to the FCoE terminal, each FCF equipment all sends to the FCoE terminal by self corresponding to the forwarding priority of FCoE terminal, and the FCoE terminal selects the FCF equipment that forwarding priority is the highest to carry out message repeating according to forwarding priority; The present embodiment has been realized the load balancing of FCF equipment, has avoided FCF apparatus of load and flow that forwarding priority is high excessive.And the present embodiment, without FCoE terminal and FCF equipment are carried out to manual configuration, just can dynamically carry out load balancing by the protocol interaction based on basic.
