Embodiment
The present invention proposes a kind of message forwarding method; Do not need in the equipment on the edge of all second interface boards of configuration high standards; But first interface board of original low specification and second interface board of high standard are mixed use, and can correctly E-Packet equally, reach aim of saving.
As shown in Figure 1, suppose that edge device of the present invention comprises master control borad 101, low specification interface board 102 and high standard interface board 103.Wherein, master control borad 101 is as the control centre of edge device system, and its function belongs to prior art, does not introduce in detail here.In addition, for describing conveniently, low specification interface board just is meant first interface board described in following examples, and the high standard interface board just is meant second interface board.
Low specification interface board 102 is receiving user side when sending to the message of remote station; Utilize the MAC hardware list of the low specification interface board self of this message inquiry; The MAC hardware list of low specification interface board self is used to preserve the MAC Address of site-local; When miss, give high standard interface board 103 with this message transmissions.
High standard interface board 103 will send from the loopback mouth from the message of low specification interface board 102; Receive from the loopback mouth and send the back and during the message that gets into once more; Utilize the MAC hardware list of this message inquiry high standard interface board 103 self; The MAC hardware list of said high standard interface board 103 self is used to preserve the MAC Address of site-local and remote station, when hitting, according to the outlet information of the MAC hardware list record of high standard interface board 103 self this message is sent to remote station.
That is to say that technical scheme of the present invention can realize like this:
Mix in the equipment on the edge of and use low specification interface board and high standard interface board, all contain the MAC hardware list of self in each interface board.Wherein, the MAC hardware list of low specification interface board is preserved the MAC Address of site-local, and the MAC hardware list of high standard interface board is preserved the MAC Address of site-local and remote station.When low specification interface board receives user side when sending to the message of remote station, utilize the MAC hardware list of the low specification interface board self of this message inquiry.Because what the MAC hardware list of low specification interface board was preserved is the MAC Address of site-local, can not hit, give the high standard interface board with this message transmissions again, send from the loopback mouth of high standard interface board.After message got into from the loopback mouth once more, the high standard interface board utilized the MAC hardware list of this message inquiry self, when hitting, according to the outlet information that writes down this message is sent to remote station.
Because edge device all do not use the high standard interface board, but will original low specification interface board and high standard interface board mixing use, but the effect through ingenious use loopback mouth can correctly E-Packet equally, reaches aim of saving with this.
The present invention program be described in detail below with preferred embodiment in order better to explain.
In the present embodiment, suppose that edge device is that Ethernet connects the edge device (ED) in virtual (EVI) network.The EVI network is a kind of network that can a plurality of data centers this type private network that the strange land is disposed be coupled together, and can between data center, carry out free migration through virtual machine, to realize purposes such as load balancing and high reliability.
Fig. 2 is the sketch map of EVI network.As shown in the figure, the EVI network is made up of core network and some station networks, and station network is exactly the data center that disposes various places, belongs to private network, and core network is exactly a public network, and promptly some private networks couple together through public network.Station network comprises edge network and access network, and wherein, edge network refers to the network between convergence device and the edge device, and access network refers to an access the network between equipment and the convergence device.Similar with other like virtual special local area network existing virtual networkings such as (VPLS); EVI also can realize the expanded function of Virtual Local Area Network between different websites; Constitute independently EVI network example on the VLAN of these expansions, transmit each other in the VLAN of different EVI instances and isolate.Certainly, other technologies such as EVI described in the present embodiment and VPLS are also had any different, but uncorrelated with the present invention program's essence, are not described in detail here.
Fig. 3 is the structural representation of edge device ED, and present embodiment is mainly described the message of how realizing among the ED in the EVI instance and transmitted.As shown in Figure 3, ED comprises:
Low specification interface board 1～4, high standard interface board 1～2, passage is mutual internally between each interface board.Certainly, in the practical application, the number of low specification interface board and high standard interface board is not limit, can be M with N, need only M, N is the integer more than or equal to 1.
The same with the existing interface plate technique, comprise on each interface board of present embodiment (not the drawing among the figure) such as port, CPU, forwarding chip and MAC hardware list of some physics.In addition, identical with prior art, ED also comprises master control borad, but does not relate to the scheme of present embodiment, also is not described in detail here.
In the present embodiment, the MAC hardware list capacity on the low specification interface board is little, and its scope can be tens K～K more than 100, only preserves the MAC Address of site-local, and said low specification interface board i.e. first interface board, links to each other with user side, and do not link to each other with the public network side.And the MAC hardware list capacity on the high standard interface board is big; Scope is 1M～tens M; Both preserved the MAC Address of site-local, and also preserved the MAC Address (all MAC Addresss in the EVI instance) of remote station, said high standard interface board i.e. second interface board; Link to each other with the public network side, and do not link to each other with user side.Here the MAC Address of so-called site-local is meant the MAC Address that edge device is learnt from local user's side, and its method is identical with prior art.The MAC Address of so-called remote station is meant the MAC Address that edge device is learnt from the public network side, can be through accomplishing like Intermediate System-to-Intermediate System (ISIS) agreement.
How to carry out mac learning, the mac learning in the user side VLAN and two aspects of mac learning of public network side are described in detail below.
One, the mac learning in the user side VLAN only limits to low specification interface board.Its method is identical with prior art; That is: in certain VLAN; Receive the user side message if belong to certain port of this VLAN; From this message, parse information such as vlan number, source MAC, the port of this vlan number, source MAC and this message of reception is noted, be issued in the MAC hardware list of self.
Such as: with Fig. 3 is example; The port one of supposing low specification interface board 1 belongs to VLAN100, receive the message of user side after, parsing its vlan number is VLAN100; Source MAC is MAC1, so information such as VLAN100, MAC1 and port one are issued in the MAC hardware list of low specification interface board 1:
| Vlan number | MAC Address | Outlet information | … |
| … | … | … | … |
| VLAN100 | MAC1 | Port one | |
| … | … | … | … |
Table one
After certain low specification interface board is learnt certain MAC Address, also need to give synchronously other low specification interface board, this is divided into two kinds of situation:
Situation one: if other low specification interface board also comprises the member port of this VLAN; No matter it is that aggregation port also is non-aggregation port that the user side message gets into the inbound port of low specification interface board, the MAC Address that needs to learn is given other the low specification interface board that comprises other member port places of this VLAN synchronously.
Such as: in this above-mentioned example, suppose that the port 2 of low specification interface board 2 also belongs to the member port of VLAN100, but do not comprise the member port of VLAN100 in the low specification interface board 3 and 4.So, need the MAC1 that will learn to give low specification interface board 2 synchronously, but need not to give synchronously low specification interface board 3 and 4.
Situation two: if study is during MAC Address; The inbound port that the user side message gets into low specification interface board is an aggregation port; For dependable flow is not better lost; The MAC Address that not only needs to learn is given other the low specification interface board that comprises this member of vlan mouth synchronously, also needs not comprise the low specification interface board of this member of vlan mouth to other synchronously, that is: need synchronously to other all low specification interface boards.
Such as: the port 2 of supposing low specification interface board 1 is aggregation ports; And the member port that belongs to VLAN200; So, no matter whether low specification interface board 2,3,4 comprises the member port of VLAN200, all need the MAC2 that will learn to give low specification interface board 2,3,4 synchronously.
Above-mentioned is the situation of site-local user side MAC Address being given synchronously low specification interface board.In addition, because the high standard interface board need be preserved MAC Addresss all in the EVI instance, therefore, the MAC Address that low specification interface board also needs to learn is given all high standard interface boards synchronously.Such as: in these above-mentioned two examples, low specification interface 1 needs the MAC1 that will learn to give high standard interface board 1 and 2 synchronously, and low specification interface board 2 also needs the MAC2 that will learn to give high standard interface board 1 and 2 synchronously.
Two, the mac learning of public network side only limits to the high standard interface board; Its method is also similar with prior art; That is: the high standard interface board of site-local is learnt the remote station information releasing through the ISIS agreement, and information such as the vlan number that obtains, MAC Address, tunnel outgoing interface are issued in the MAC hardware list of self.
Such as: with Fig. 3 is example, supposes that high standard interface board 1 learns the remote station information releasing through the ISIS agreement, knows that vlan number is VLAN300, and MAC Address is MAC3, and the tunnel outgoing interface is an interface 3, then is issued in self the MAC hardware list to be:
| Vlan number | MAC Address | Outlet information | … |
| … | … | … | … |
| VLAN300 | MAC3 | Interface 3 | |
| … | … | … | … |
Table two
The outlet information implication that it should be noted that the outlet information that writes down in the high standard interface board and low specification interface board record is different.In low specification interface board, outlet information is the port numbers of low specification interface board, receives the inbound port of its message when just learning MAC Address, is physical port.And in the high standard interface board, outlet information is the tunnel outgoing interface, come by the remote station issue, and be logic interfacing, its particular content comprises the information such as outbound port that vlan number, public network of tunnel header, public network.
In addition, because the high standard interface board will be preserved all MAC Addresss in the EVI instance, so after learning the MAC Address of public network side, also need synchronously to other all high standard interface boards.
After carrying out about the example of learning MAC1～MAC3 above, the example of each interface board preservation MAC Address is as shown in Figure 4.Wherein, MAC1 is kept at low specification interface board 1 and 2, and in high standard interface board 1 and 2, MAC2 is kept in all low specification interface board and high standard interface board, and MAC3 only is kept in all high standard interface boards.
More than be about the part of interface board study and synchronous MAC Address, further introduce the part that message is transmitted below.
Still with reference to figure 3, suppose that the port one of low specification interface board 1 receives the user side message, this message need send to remote station, supposes that also the broadcasting outgoing interface of unknown unicast is set to the loopback mouth of high standard interface board 1.This method comprises:
S1: low specification interface board 1 receives the message that user side sends to remote station from port one, and the MAC that triggers in the EVI instance searches, and utilizes the MAC hardware list of the low specification interface board of target MAC (Media Access Control) address inquiry in this message 1 self that is:.Here, because the low specification interface board 1 in the present embodiment has only been preserved the MAC Address of site-local, the inquiry nature can not hit.
S2: when miss, low specification interface board 1 is broadcasted this message in this VLAN.The broadcasting outgoing interface of the unicast message of present embodiment the unknown is set to the loopback mouth of high standard interface board; So; Message is broadcasted to be actually through the inner passage in this VLAN and is transferred to high standard interface board 1, and sends from the loopback mouth of high standard interface board 1.
This step is that hypothesis sends message to high standard interface board 1, but can also be arranged to be transferred to other high standard interface boards in the practical application.Perhaps, for the reason of load balancing, the loopback mouth of high standard plate that can also be all is set to aggregation port, and confirms message transmissions is given the loopback mouth of which high standard interface board through Hash operation.
Should be noted that to be that the loopback mouth is a loopback circuit of transmitting chip internal in the interface board, the message of going out from this mouthful will directly return, and can not send from the external physical port of interface board.
S3: high standard interface board 1 receives the message that sends the back and get into once more from the loopback mouth, and the MAC that triggers in the EVI instance searches, and utilizes the MAC hardware list of the target MAC (Media Access Control) address inquiry high standard interface board 1 self in this message that is:.Here, will be used as the message that newly receives by high standard interface board 1 from the message of the salty new entering of loopback equally handles.
S4: when hitting, high standard interface board 1 sends to remote station according to the outlet information of the MAC hardware list record of self with this message.Partly describe as the front mac learning; The MAC hardware list of high standard interface board can write down information such as vlan number, MAC Address, tunnel outgoing interface; Message is sent to remote station need be obtained like information such as tunnel header, public network outbound ports from tunnel outgoing interface information before; After carrying out message encapsulation according to these information then, send to public network from the outbound port of high standard interface board 1.
Top step S4 is that the high standard interface board is searched the situation that MAC Address hits, and in the practical application, if miss, then need in whole VEI instance, broadcast, that is: all tunnel outgoing interfaces of high standard interface board 1 public network side all can be transmitted this message.In addition, all member ports of this VLAN of user side also can be transmitted this message, that is: the member port of low all these VLAN of specification interface board all can be transmitted this message.
With reference to figure 3, if high standard interface board 1 port one receives public network side message, this message need send to the user side of site-local, and this method comprises:
D1: high standard interface board 1 receives the message that the public network side sends to the site-local user side, and the MAC that triggers in the EVI instance searches: the MAC hardware list of utilizing this message inquiry high standard interface board 1 self.
Because the message of receiving from the public network side joint is the process of passing through tunnel encapsulation; Need in the practical application to look into the MAC hardware list again after the decapsulation; Such as: if the tunnel adopts the IP gre tunneling, so just need to carry out the operation of ejecting the IP gre tunneling earlier, carry out MAC afterwards again and search; This is well known to a person skilled in the art, is not described in detail here.
D2: if hit, will this message be transmitted to the site-local user side according to the outlet information of the MAC hardware list record of high standard interface board 1 self, and process ends.
Because the target MAC (Media Access Control) address of message is the MAC Address of site-local user side, so corresponding outlet information should be the port of low specification interface board, such as the port one that is low specification interface board 1.High standard interface board 1 just should send to low specification interface board 1 with message through the inner passage, is transmitted to user side by low specification interface board 1 from port one again.
D3: if miss, then this message is broadcasted in this VLAN, that is: the member port that belongs to this VLAN on all low specification interface boards all can be transmitted to user side with this message, then process ends.
It is because should send to the site-local user side from the message of public network side that this step is broadcasted in VLAN, only need transmit through the member port of this VLAN, and because level is cut apart, the high standard interface board can not be transmitted to the public network side yet.
Present embodiment is that example is introduced the present invention program with edge device among the EVI, but in the practical application, also can on other network equipments, implement, and such as edge device PE on the VPLS etc., does not receive the restriction of the embodiment of the invention.
Use the present invention program, can original low specification interface board be mixed with the high standard interface board that increases newly and use, but can correctly E-Packet equally, thereby realize aim of saving.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
