Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The flow chart of the message forwarding method that Figure 1A provides for one embodiment of the invention.As shown in Figure 1A, the method for the present embodiment comprises:
Step 101, source Rbridge are according to the target MAC (Media Access Control) address of the current ethernet data frame receiving, and inquiry MAC shows, and obtains the mark of the first object Rbridge.
In TRILL network, each Rbridge is by the mutual learning MAC address of ESADI and generate MAC table.In MAC table, mainly store the MAC Address of terminal equipment that in TRILL network, each edge Rbridge connects and the corresponding relation of the MAC Address of terminal equipment and edge Rbridge.In addition, in MAC table, also store the mark of each edge Rbridge.In TRILL network, the mark of Rbridge is called as the nickname of Rbridge.Wherein, edge Rbridge both referred to and was connected with other Rbridge in TRILL network, the Rbridge being connected with the terminal equipment outside TRILL network again.In the present embodiment, the first object Rbridge is the edge Rbridge that the terminal equipment corresponding with target MAC (Media Access Control) address is connected.
In TRILL network, each Rbridge has a TRILL routing table, mainly stores MAC Address and the outgoing interface information of the nickname of each Rbridge and the down hop Rbridge of this Rbridge of arrival.Rbridge generates TRILL routing table by SPF algorithm.
The source Rbridge of the present embodiment refers to the edge Rbridge that receives ethernet data frame.That is to say, source Rbridge is connected with the terminal equipment of the transmission ethernet data frame outside TRILL network.Further, if when source Rbridge and other Rbridge belong to a shared link, source Rbridge still forwards Rbridge, the Rbridge with forwarding capability electing according to forwarding Rbridge election mechanism.So-called shared link mainly refers to the shared link of Ethernet, in same VLAN (Virtual Local Area Network; Referred to as: the link VLAN), the two or more Rbridge on same shared link is communicated with on physical link He on two layers of link like this, and the also while and same station terminal equipment connection of these Rbridge.As shown in Figure 1B, Rbridge1 is connected with Rbridge2, and Rbridge1 and Rbridge2 be connected with terminal equipment 3 simultaneously, thereby forms a shared link.
Concrete, the terminal equipment being connected with source Rbridge sends ethernet data frame to source Rbridge.Source Rbridge receives ethernet data frame, then, according to the target MAC (Media Access Control) address inquiry MAC table of ethernet data frame, obtains the terminal equipment that target MAC (Media Access Control) address is corresponding and belongs to that Rbridge, obtains the nickname of the first object Rbridge of the present embodiment.
Step 102, source Rbridge, according to the mark of the first object Rbridge, inquire about the direct-connected list of neighbours of the first object Rbridge, obtain the mark of the second object Rbridge direct-connected with the first object Rbridge.
Wherein, describedly direct-connectedly refer to that two Rbridge are directly connected by physical link, and two Rbridge are also communicated with on two layers of link.In the present embodiment, the first object Rbridge and the second object Rbridge, except direct-connected, are also connected with the recipient of ethernet data frame simultaneously, thereby form a shared link.In this explanation, in various embodiments of the present invention, all Rbridge direct-connected with the first object Rbridge and that the terminal equipment corresponding with target MAC (Media Access Control) address is connected simultaneously are all called as the second object Rbridge, that is to say that in various embodiments of the present invention, said the second object Rbridge may be that a Rbridge may be also many Rbridge.Wherein, to basic identical with the processing of direct-connected every the Rbridge of the first object Rbridge, therefore various embodiments of the present invention mainly describe as an example of a second object Rbridge example.
Describe as an example of shared link shown in Figure 1B example: in the time there is shared link in TRILL network, for the ethernet data frame that is terminal equipment 3 for destination address, will have two forward-paths, now will there will be loop.In order to address this problem, Rbridge1 in shared link and Rbridge2 can elect a forwarding Rbridge (for example Rbridge1) by forwarding Rbridge election mechanism, and selected from two Rbridge by this forwarding Rbridge a Rbridge as the information announcement of the forwarding person of message on this shared link the Rbridge using this as forwarding person to whole TRILL network, be responsible for forwarding the ethernet data frame on this shared link by this Rbridge as forwarding person.Conventionally, forward Rbridge and can select the own forwarding person as message on shared link, Rbridge1 is the forwarding person on shared link.Now, Rbridge1 is by information announcement such as the MAC Address of the nickname of oneself and the terminal equipment 3 being connected with oneself to other Rbridge in Trill network, and other Rbridge in Trill network just know that the outlet Rbridge of incoming terminal equipment 3 is Rbridge1 like this.And for another Rbridge on shared link, it is the relevant information between Rbridge2 and terminal equipment 3, Rbridge1 can not notice to other Rbridge in TRILL network, like this because other Rbridge in network do not know the relevant information between Rbridge2 and terminal equipment 3, just do not know that Rbridge2 can be transmitted to ethernet data frame terminal equipment 3 yet, realize the object that interface Rbridge2 is upper and that terminal equipment 3 is direct-connected gets clogged, also just to have prevented that Rbridge2 from also forwarding ethernet data frame to terminal equipment 3.In addition, because Rbridge2 is not elected as the forwarding Rbridge on this shared link, therefore Rbridge2 also can not notice the relevant information between itself and terminal equipment 3 to other Rbridge in TRILL network.
Although such scheme has solved loop problem, but the waste of network bandwidth resources will be caused because forward-path is idle, therefore in various embodiments of the present invention, whether be elected as the Rbridge that forwards Rbridge notices relevant information from other Rbridges direct-connected with it to all Rbridge in TRILL network, nickname, the priority of for example other Rbridge, be the information such as forwarding Rbridge.In network, every Rbridge can be known the Rbridge relevant information on shared link in network like this, and for example which platform Rbridge is elected as forwards Rbridge, with the information etc. that forwards the direct-connected Rbridge of Rbridge.For every Rbridge in network, the relevant information of comparatively preferably noticing according to the forwarding Rbridge on shared link generates the direct-connected list of neighbours of this forwarding Rbridge, and relevant information is stored in the direct-connected list of these neighbours.
Based on above-mentioned, source Rbridge can go to search according to the nickname of the first object Rbridge the direct-connected list of neighbours of the first object Rbridge, obtains other Rbridges direct-connected with the first object Rbridge (i.e. the second object Rbridge).In the present embodiment, the first object Rbridge and the second object Rbridge are connected with the recipient of ethernet data frame (being the terminal equipment that the target MAC (Media Access Control) address of ethernet data frame is corresponding) simultaneously.
Step 103, source Rbridge are according to TRILL routing table, by ethernet data frame other ethernet data frames identical with the follow-up target MAC (Media Access Control) address receiving, be transmitted to by the first object Rbridge and the second object Rbridge the terminal equipment that target MAC (Media Access Control) address is corresponding.
Source Rbridge is obtaining after the first object Rbridge and the second object Rbridge, uses respectively two forward-paths at the first object Rbridge and the second object Rbridge place that other identical with the target MAC (Media Access Control) address of current ethernet data frame with the follow-up target MAC (Media Access Control) address receiving current ethernet data frame ethernet data frames are transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding.When the second object Rbridge is many during with the direct-connected Rbridge of the first object Rbridge, source Rbridge will be transmitted to by other identical with the target MAC (Media Access Control) address of current ethernet data frame with the follow-up target MAC (Media Access Control) address receiving current ethernet data frame ethernet data frames the terminal equipment that target MAC (Media Access Control) address is corresponding by many forward-paths at the first object Rbridge and the second object Rbridge place.
Concrete, source Rbridge connects to receive ethernet data frame, therefore source Rbridge can be transmitted to by the first object Rbridge the terminal equipment that target MAC (Media Access Control) address is corresponding by part ethernet data frame, and another part ethernet data frame is transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding by the second object Rbridge, and along with the continuous reception of ethernet data frame, final by using in turn the first object Rbridge and the second object Rbridge that all ethernet data frames are transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding.Wherein, for the first object Rbridge, source Rbridge gets the down hop Rbridge of the first object Rbridge according to its TRILL routing table, and the ethernet data frame that sends to the first object Rbridge is encapsulated as to TRILL Frame, then forwarded hop-by-hop is given the first object Rbridge.The first object Rbridge receives after TRILL Frame, the TRILL Frame receiving is carried out to decapsulation and obtain the ethernet data frame that enters at first TRILL network, and according to the target MAC (Media Access Control) address in ethernet data frame, ethernet data frame is transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding.For the second object Rbridge, source Rbridge is transmitted to the second object Rbridge after the ethernet data frame that sends to the second object Rbridge being encapsulated as to TRILL Frame according to TRILL routing table equally.Just in the present embodiment, source Rbridge be by the direct-connected list of neighbours of the first object Rbridge know the second object Rbridge also can forwarding data frame to terminal equipment corresponding to target MAC (Media Access Control) address, thereby obtain the second object Rbridge's.The second object Rbridge also can carry out decapsulation to the TRILL Frame receiving receiving after TRILL Frame, and the ethernet data frame that decapsulation is got is transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding.Concerning the second object Rbridge, in the time that ethernet data frame is the terminal equipment arriving on the shared link being connected between itself and the first object Rbridge, just mean that the direct-connected interface of the second object Rbridge and this terminal equipment will be opened, and then be transmitted to terminal equipment by ethernet data frame.
The message forwarding method of the present embodiment, source Rbridge inquires after object Rbridge according to the target MAC (Media Access Control) address of ethernet data frame, the further direct-connected list of neighbours of inquiry object Rbridge, obtain the other object Rbridge direct-connected with this object Rbridge, and all ethernet data frames identical with the target MAC (Media Access Control) address of current ethernet data frame the target MAC (Media Access Control) address receiving are transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding by the forward-path at all object Rbridge place on shared link, realize the forwarding of ethernet data frame, forward ethernet data frame owing to taking full advantage of the bandwidth resources of every forward-path on shared link, improve the utilance of the network bandwidth, reduce the waste of link bandwidth resource, improve the forwarding rate of ethernet data frame.
The flow chart of the message forwarding method that Fig. 2 provides for another embodiment of the present invention.As shown in Figure 2, the method for the present embodiment comprises:
Step 201, TRILL netinit, the Rbridge in TRILL network on shared link, according to forwarding Rbridge election mechanism, forwards the election of Rbridge.
Conventionally,, in the time of TRILL network startup, the Rbridge in TRILL network on shared link will forward the election of Rbridge.Wherein, forward Rbridge election and belong to prior art, do not repeat at this.After electing forwarding Rbridge, specify a Rbridge to be responsible for forwarding the message on this shared link as the forwarding person of shared link by forwarding in the two or more Rbridge of Rbridge from shared link, and the information announcement of the Rbridge of appointment is gone out.In various embodiments of the present invention, all the forwarding person take forwarding Rbridge appointment oneself as shared link is as example.
In the present embodiment, the Rbridge that is elected as forwarding Rbridge can broadcast neighbor advertisement message to all Rbridge in TRILL network.Comprise and the nickname that forwards the direct-connected Rbridge of Rbridge in neighbor advertisement message.
In addition, forward Rbridge can also by forward the priority of Rbridge and with other information announcement such as priority that forward the direct-connected Rbridge of Rbridge to all Rbridge in TRILL network.Wherein, forwarding Rbridge can also be added on the information such as priority in neighbor advertisement message and be broadcast to together all Rbridge in TRILL network with nickname.Forward Rbridge also can be by other notice message by information broadcastings such as priority to all Rbridge in TRILL network.
Each Rbridge in step 203, TRILL network receives the neighbor advertisement message that forwards Rbridge broadcast.
In the time there is the neighbor advertisement message of broadcast in TRILL network, each Rbridge receives neighbor advertisement message, then stores in the direct-connected list of neighbours that forwards Rbridge sending the nickname of direct-connected Rbridge with forwarding Rbridge carrying in the nickname, neighbor advertisement message of forwarding Rbridge of neighbor advertisement message.
In addition, forward Rbridge and when forwarding other information such as priority of the direct-connected Rbridge of Rbridge when carrying in neighbor advertisement message, the Rbridge that receives neighbor advertisement message also can will forward Rbridge's and the information such as priority of direct-connected Rbridge stores in the direct-connected list of neighbours that forwards Rbridge with forwarding Rbridge.
In the present embodiment, if when the first object Rbridge is also the Rbridge on shared link, also can forward according to forwarding Rbridge election mechanism the election of Rbridge, and in the time that it is elected as the forwarding Rbridge on shared link, also can be to TRILL Web broadcast neighbor advertisement message.And source Rbridge can receive the neighbor advertisement message of the first object Rbridge broadcast.In like manner, if the source Rbridge of the present embodiment is also on shared link time, also can forward according to forwarding Rbridge election mechanism the election of Rbridge, and in the time that it is elected as the forwarding Rbridge on shared link, also can be to TRILL Web broadcast neighbor advertisement message.
In the present embodiment, the neighbor advertisement message of the first object Rbridge broadcast is referred to as to the first neighbor advertisement message, in this first neighbor advertisement message, mainly comprises the nickname of the second object Rbridge direct-connected with the first object Rbridge.And the neighbor advertisement message of source Rbridge broadcast is referred to as to the second neighbor advertisement message, in this second neighbor advertisement message, mainly comprise the nickname of the Rbridge direct-connected with former Rbridge.
If when the first object Rbridge is not the Rbridge on shared link, it can not forward the election of Rbridge, just can not broadcast neighbor advertisement message yet, the direct-connected list of neighbours of upper the first object Rbridge of source Rbridge just can not store any information yet, and now source Rbridge can carry out forward process to ethernet data frame according to prior art.
Step 207, source Rbridge obtain the nickname of the second object Rbridge direct-connected with the first object Rbridge from the direct-connected list of neighbours.
Wherein, allocation proportion is manual configuration in advance, also can be according to certain rule generation.For example: supposing allocation proportion pre-configured is 1: 1, and source Rbridge can forward according to the pro rate of 1: 1 ethernet data frame receiving to the forward-path at the first object Rbridge and the second object Rbridge place.For example: source Rbridge can distribute to the first object Rbridge or the second object Rbridge in turn by receiving each ethernet data frame.Again for example: source Rbridge can distribute to the first object Rbridge or the second object Rbridge as one group in turn using receiving every 5 ethernet data frames.Except allocation proportion is 1: 1, can also configure allocation proportion and be 1: 2,2: 1,3: 1 etc.
Further, before the first object Rbridge inquires about the direct-connected list of neighbours of the first object Rbridge at source Rbridge, while noticing other information such as the priority of the first object Rbridge and the priority of the second object Rbridge to source Rbridge, source Rbridge can also store in the direct-connected list of neighbours of the first object Rbridge with information such as priority the second object Rbridge the first object Rbridge.Source Rbridge can obtain the first object Rbridge and priority the second object Rbridge from the direct-connected list of the neighbours of the first object Rbridge, and according to the first object Rbridge and priority the second object Rbridge, dynamically generate allocation proportion.For example: in the time there is a second object Rbridge, the priority of establishing the first object Rbridge is 2, and the priority of the second object Rbridge is 1, can generate the allocation proportion of 2: 1, but is not limited to this.Again for example: in the time there is two the second object Rbridge, if the priority of the first object Rbridge is the priority of 4, one the second object Rbridge is 3, the priority of another second object Rbridge is 1, can generate the allocation proportion of 4: 3: 1, but be not limited to this.Present embodiment just, take the priority of the first object Rbridge and the second object Rbridge as foundation, can generate different allocation proportions.Wherein, the priority of the first object Rbridge and the second object Rbridge can embody the quality of the first object Rbridge and the second object Rbridge place forward-path to a certain extent, therefore obtain allocation proportion and carry out the distribution of ethernet data frame based on the allocation proportion of obtaining according to precedence information, can make network bandwidth resources obtain more reasonably utilizing, further improve the forward efficiency of ethernet data frame.
Step 209, source Rbridge are according to TRILL routing table, the ethernet data frame that distributes the first object Rbridge or the second object Rbridge is encapsulated as to TRILL Frame, then TRILL Frame is sent to the first object Rbridge or the second object Rbridge.
For the ethernet data frame of distributing to the first object Rbridge or the second object Rbridge, the processing mode of source Rbridge is identical, and difference is that packaged TRILL header is different.Be elaborated as example take the repeating process of the data message of distributing to the first object Rbridge below.
Source Rbridge, according to TRILL routing table, obtains the down hop Rbridge of the first object Rbridge, and the outgoing interface of down hop Rbridge.Then, source Rbridge is at the outside of ethernet data frame encapsulation TRILL header, concrete, source Rbridge is by the nickname that enters Rbridge field and be filled to source Rbridge in TRILL header, be filled to the nickname of the first object Rbridge by going out Rbridge field, and fill respectively other respective field in TRILL header.Then, source Rbridge packaged source MAC Address outside TRILL header be MAC Address, the target MAC (Media Access Control) address of source Rbridge be the MAC Address of down hop Rbridge and fill VLAN mark (VLAN Tag) after send to down hop Rbridge.Down hop Rbridge receives TRILL Frame, know the first object Rbridge according to the Rbridge field that goes out in TRILL header, then again TRILL Frame is transmitted to its down hop Rbridge according to TRILL routing table, until the first object Rbridge receives TRILL Frame.
Step 210, the first object Rbridge or the second object Rbridge receive TRILL Frame, and the TRILL Frame receiving is carried out to decapsulation processing and obtain ethernet data frame, and ethernet data frame is transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding, until end operation while having forwarded all ethernet data frames.
Wherein, it is identical that the first object Rbridge and the second object Rbridge receive processing operation after TRILL Frame, therefore describe as an example of the first object Rbridge example.
The first object Rbridge receives after TRILL Frame, according to going out Rbridge field and know oneself to be exactly Rbridge in TRILL header, TRILL header is removed, obtain the ethernet data frame that initially enters TRILL network, then according to the target MAC (Media Access Control) address of ethernet data frame, directly ethernet data frame is sent to the terminal equipment that target MAC (Media Access Control) address is corresponding, complete the forwarding of ethernet data frame.
Step 211, source Rbridge are directly according to TRILL routing table, current ethernet data frame and follow-up other ethernet data frames that receive are encapsulated as respectively to TRILL Frame, and TRILL Frame is sent to the first object Rbridge, and perform step 212.
Wherein, when step 211 and step 212 have been described the first object Rbridge and have not been the Rbridge on shared link, the process of TRILL forwarded ethernet data frame, it is same as the prior art, source Rbridge directly carries out the forwarding of ethernet data frame according to TRILL routing table, do not repeat them here.
The message forwarding method of the present embodiment, source Rbridge inquires after object Rbridge according to the target MAC (Media Access Control) address of ethernet data frame, the further direct-connected list of neighbours of inquiry object Rbridge, obtain the other object Rbridge direct-connected with this object Rbridge, and all ethernet data frames identical with the target MAC (Media Access Control) address of current ethernet data frame the target MAC (Media Access Control) address receiving are transmitted to the terminal equipment that target MAC (Media Access Control) address is corresponding by the forward-path at all object Rbridge place on shared link, realize the forwarding of ethernet data frame, forward ethernet data frame owing to taking full advantage of the bandwidth resources of every forward-path on shared link, improve the utilance of the network bandwidth, reduce the waste of link bandwidth resource, improve the forwarding rate of ethernet data frame.
The technical scheme of various embodiments of the present invention is more clearly described to be formed shared link by two Rbridge as example below in conjunction with concrete TRILL network scenarios.
As shown in Figure 3, this TRILL network is built into and is formed by Rbridge31-Rbridge35, for the message of transmission terminal equipment.Wherein, main frame 36 and main frame 37 are the terminal equipments outside TRILL network, main frame 37 connects on the shared link A of Rbridge33 and Rbridge34, that is to say that Rbridge33 is directly connected physically with Rbridge34, and main frame 37 is also connected with Rbridge34 with Rbridge33 respectively, form shared link structure as shown in Figure 1B.Suppose that main frame 36 sends a clean culture ethernet data frame and will arrive main frame 37.
In the present embodiment, Rbridge33 and Rbridge34 are in advance according to forwarding Rbridge election mechanism, electing Rbridge33 is the forwarding Rbridge on this shared link A, and Rbridge33 select oneself be the forwarding person of the message on shared link A and by information announcement such as the MAC Address of the nickname of oneself and main frame 37 to whole TRILL network, Rbridge33 is responsible for the ethernet data frame on this shared link A to be transmitted to main frame 37.In the present embodiment, determining it oneself is to forward after Rbridge, Rbridge33 is to whole TRILL Web broadcast neighbor advertisement message.Wherein, the priority that the priority of Rbridge33 is 2, Rbridge34 is 1.This neighbor advertisement message comprises following information: nickname, the forwarding Rbridge, 2 of shared link A:(Rbridge33), (nickname of Rbridge34, sky (NULL), 1) }, concrete upper two Rbridge of existence of shared link A that represent, wherein Rbridge33 is forwarding Rbridge, and its priority is 2; Wherein Rbridge34 is the direct-connected Rbridge of Rbridge33, and it not forwards Rbridge, and priority is 1.
