Embodiment
In order to increase the quantity of available sub-interface, avoiding the formation of message repeating bottleneck, improving message forwarding performance, embodiments providing a kind of ports-Extending and message processing method, device and the network equipment.
Below in conjunction with Figure of description, the preferred embodiments of the present invention are described, be to be understood that, preferred embodiment described herein is only for instruction and explanation of the present invention, be not intended to limit the present invention, and when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
As shown in Figure 1, for the hardware configuration schematic diagram of the embodiment of the present invention, the upper united mouth (port4 namely in Fig. 1) of exchange chip is connected with CPU route mouth, and the route mouth (also referred to as WAN mouth, the port0-port3 namely in Fig. 1) of exchange chip can be used for expanding sub-interface.Based on the hardware structure diagram that Fig. 1 provides, embodiments provide a kind of method utilizing the route mouth of exchange chip to carry out sub-interface expansion, can by being configured realization to the route mouth of exchange chip, concrete, as shown in Figure 2, for the implementing procedure schematic diagram of the ports-Extending method that the embodiment of the present invention provides, can comprise the following steps:
The port type of at least one route mouth of S21, configuration exchange chip is preset port type.
During concrete enforcement, preset port type refers to the port type supporting ports-Extending, and such as Trunk type port or Hybrid type port etc., the embodiment of the present invention does not limit this.For Fig. 1, the route mouth port0-port3 by exchange chip is configured to Trunk type port or Hybrid type port.
The upper united mouth that the route mouth that the Port-Based VLAN that S22, configuration are configured to the route mouth of preset port type points to CPU connects.
During concrete enforcement, owing to the route mouth of exchange chip being set to Trunk port or Hybrid port can introduce another one problem, i.e. two layers of forwarding of message, in order to avoid two layers of forwarding of message, in the embodiment of the present invention, the Port-Based VLAN being configured to the route mouth of Trunk port or Hybrid port is pointed to the upper united mouth be connected with the route mouth of CPU.In Fig. 1, the Port-Based VLAN namely configuring route mouth port0-port3 points to port4.
S23, distribute different primary vlan mark respectively for the route mouth being configured to preset port type, and when utilizing this route mouth to expand sub-interface, be that the sub-interface of expansion distributes Sub-VLAN mark.
During concrete enforcement, message that the route mouth of CPU receives which the route mouth from exchange chip can be identified in order to make CPU software, be required to be exchange chip route mouth during initialization and configure different primary vlan marks, when specifically implementing, can consider to distribute the VLAN be of little use mark.After certain route mouth of the exchanged chip of message receives, according to existing exchange regulation, the message not carrying VLAN mark identifies if the message carrying VLAN mark then retains its VLAN, if then can add the primary vlan mark of this route mouth on message.After the route mouth of CPU receives message, according to receiving the bcm tag of message, CPU software judges that whether message is from exchange chip, if the VLAN mark of then being carried by analytic message from exchange chip is identified specifically from which route mouth of exchange chip.
It should be noted that, primary vlan mark or Sub-VLAN mark be from VLAN mark select, just in order to the VLAN of the VLAN mark and sub-interface of distinguishing main interface identifies in the embodiment of the present invention, the VLAN distributed for main interface mark is called that primary vlan identifies, the VLAN distributed for sub-interface mark is called that Sub-VLAN identifies.
For Fig. 1, can identify as the primary vlan of main interface for route mouth port0 ~ port3 distributes VLAN mark respectively, when utilizing the arbitrary route mouth in port0 ~ port3 to carry out sub-interface expansion, can identify as the Sub-VLAN of sub-interface for the sub-interface of expansion distribute VLAN mark.Such as, for port3 distributes primary vlan mark 2012, the sub-interface expanded for utilizing port3 distributes Sub-VLAN mark 12.
Wherein, Sub-VLAN mark can be configured voluntarily by user, when user configured Sub-VLAN mark identifies identical with the primary vlan distributed, in order to avoid conflict, in during the embodiment of the present invention, dynamic conditioning can be carried out to the VLAN mark of distributing for main interface or sub-interface.Such as, during concrete enforcement, the primary vlan distributed for port0 is designated 4011, and user is configured with the Sub-VLAN mark of sub-interface when being also 4011 on route mouth port0, in this case, again choose a VLAN mark in the VLAN mark that never can be assigned with for main interface as primary vlan mark, the process that dynamic conditioning VLAN identifies is transparent for user, user's not perception.
Preferably, during concrete enforcement, bitmap can be adopted to store each VLAN and to identify its corresponding label information whether be assigned with, during concrete enforcement, whether by the label information that use adopted 1 bit position store, time initial, every corresponding position is set to 0 if 4094 VLAN being identified each VLAN mark, after being assigned with, this VLAN being identified corresponding position and is set to 1.Like this, when needs distribute VLAN mark for primary vlan or Sub-VLAN, be that the VLAN mark of 0, random selecting VLAN mark is distributed from correspondence position.Because each label information only need take a bit, therefore adopt bitmap mode greatly can save memory space.Certainly, also can be that the mode of usage data table stores each VLAN and identifies corresponding relation between the label information corresponding with it, as shown in table 1, show when wherein label information is 1 that this VLAN mark is assigned with, when label information is 0, show that this VLAN mark is not assigned with.Store compared to employing bitmap mode, tables of data mode takies more memory space.
Table 1
| VLAN identifies | Label information |
| 1 | 1 |
| 2 | 0 |
| …… | …… |
| 4094 | 0 |
Pass through said method, route mouth can be expanded to multiple sub-interface, because exchange chip may comprise multiple route mouth, as 4 mouthfuls, 8 mouthfuls even 24 mouthfuls, 48 mouthfuls, each route mouth can expand to 4094 sub-interfaces, the exchange chip of 8 mouthfuls in this way, so can expand 8 route main interfaces, and 8*4094 route sub-interface, on the other hand, may be used for owing to there being multiple route mouth expanding sub-interface, like this, the extendible amount of sub-interface of each route mouth will lack many compared to being carried out expansion by a route mouth, thus, each route needs message amount to be processed greatly to reduce, avoid message repeating bottleneck, improve message forwarding performance.
Based on above-mentioned ports-Extending method, the message received to achieve a butt joint or transmission message process, in the embodiment of the present invention, CPU needs pin to be every Single port of exchange chip, set up a corresponding Port Management table, wherein store each VLAN mark be assigned with and whether it is corresponding relation between primary vlan identifies or Sub-VLAN identifies label information.Such as, for port port0, can according to the form storage port management table shown in table 2:
Table 2
Concrete, often configuration or a deletion sub-interface, CPU revises above-mentioned Port Management table, add or delete corresponding record, as be configured with sub-interface for port0 and for its distribute VLAN be designated 10, then the main interface correspondence position in the Port Management table of port 0 correspondence is set to FALSE, sub-interface correspondence position is set to TRUE.Accordingly, when deleting sub-interface, need to delete corresponding record.
It should be noted that, when adding or delete sub-interface, all needing with the BCM5284 of CPU (register) synchronous, otherwise may occur that CPU cannot receive or send the problem of message.
Based on the Port Management table stored, CPU, when processing the message received, can perform according to the step shown in Fig. 3:
The message that S31, the arbitrary route mouth receiving exchange chip are submitted to by upper united mouth.
During concrete enforcement, the message received due to exchange chip had both been likely the message in local area network (LAN), also be likely the message of wide area network, therefore, the message that the route mouth of exchange chip receives may carry VLAN TAG (VLAN label), i.e. TAG message, TAG message is local area network (LAN) message, also likely do not carry VLAN TAG, i.e. UNTAG message, UNTAG message is wide area network message.In general, TAG message is the message sending to sub-interface, and UNTAG message is the message sending to main interface.
According to exchange regulation, for UNTAG message and wide area network message, exchange chip can add VLAN TAG in the message received, VLAN mark in VLAN TAG is set to the primary vlan mark of the route mouth receiving UNTAG message, the message that arbitrary route mouth of exchange chip receives will submit to CPU process from upper united mouth, the VLAN of upper united mouth is designated default value, is 1.In addition, according to exchange regulation, if if the VLAN mark of the message sent from upper united mouth identifies different from the VLAN of this upper united mouth, then carry VLAN TAG to send, that is, for UNTAG message, the VLAN in the VLAN TAG of the message that CPU receives is designated the primary vlan mark of the route mouth receiving message.
For TAG message and local area network (LAN) message, after arbitrary route mouth of exchange chip receives TAG message, according to exchange regulation, the TAG message that arbitrary route mouth receives can submit to CPU from upper united mouth, and equally, the VLAN of upper united mouth is designated default value, is 1.In addition, if if the VLAN mark of the message sent from upper united mouth identifies different from the VLAN of this upper united mouth, then carry VLAN TAG and send.
Wherein, the VLAN that carries in VLAN TAG mark is as follows: if the message carrying TAG received for sub-interface, then wherein carry Sub-VLAN and identify, if receive for main interface carry TAG message, then wherein carry primary vlan and identify.It should be noted that, if main interface receives the message carrying TAG, the VALN mark being then illustrated as main interface distribution identifies identical causing with the VLAN of the sub-interface utilizing same route mouth to expand, due in the embodiment of the present invention, when carrying out the configuration of route mouth, for VLAN identification collision meeting dynamic conditioning, therefore, the VLAN mark of carrying in the TAG message that the route mouth of exchange chip receives may be only Sub-VLAN mark.
S32, CPU, according to the Port Management table of the route mouth correspondence of submission message, judge whether the VLAN mark of carrying in message is primary vlan mark, if so, performs step S33, if not, performs step S34.
E-Packet after VLAN TAG in S33, deletion message, flow process terminates.
During concrete enforcement, CPU, after receiving message, searches corresponding Port Management table, judge whether the VLAN mark in VLAN TAG is primary vlan mark, if primary vlan mark, CPU forwards this message after deleting VLAN TAG wherein, if be that sub-VLA identifies, CPU directly forwards this message.
S34, to E-Packet.
So far, CPU completes the handling process to the message received.
For CPU, the flow process that the message that port0 submits to processes is described below, supposes that the primary vlan of port0 is designated 9.
If the message that Port0 receives is TAG message, illustrate that it is local area network (LAN) message, namely this message is that the sub-interface utilizing port0 to expand receives.Port0 sends it to port4, this message is through port4, because the VLAN mark in VLAN TAG identifies different from the VLAN of port4, port4 retains former VLAN TAG, namely the Sub-VLAN mark of the sub-interface of TAG message is received, and the message received is submitted to CPU, according to the VLAN mark in VLAN TAG, CPU determines that it is Sub-VLAN mark, then directly forward.
If the message that port0 receives is UATAG, illustrate that it is wide area network message, namely this message is the message that main interface receives, owing to not carrying VLAN TAG in message, the VLAN that the main VALN that then port0 adds self wherein identifies as message identifies, and send it to port4, port4 is after receiving message, because the VLAN mark in VLAN TAG identifies different from the VLAN of port4, port4 retains former VLAN TAG, namely the primary vlan mark of the main interface of UNTAG message is received, and the message received is submitted to CPU, according to the VLAN mark in VLAN TAG, CPU determines that it is primary vlan mark, E-Packet again after deleting VALNTAG.
Below introduce the handling process of CPU process message to be sent, for message to be sent, CPU can process according to the flow process shown in Fig. 4:
S41, when there being message to need to send, from the message queue to be sent of route mouth correspondence, obtain the message that will send.
During concrete enforcement, when needing when there being message to send, CPU will need the message sent to go out team from the message queue to be sent of each route mouth correspondence.
S42, judge obtain message in whether carry VLAN TAG, if so, perform step S43, otherwise, perform step S45.
S43, according to the VLAN mark comprised in VLAN TAG, from Port Management table, search corresponding route mouth.
During concrete enforcement, if the message needing the main interface of exchange chip to send, then do not carry VLAN TAG in message, therefore, according to whether carrying in message VLAN TAG, CPU can judge that this message should send to main interface or sub-interface.
If carry VLAN TAG in message, according to the VLAN mark in VLAN TAG, search from Port Management table its correspondence route mouth, and send this message to the route mouth found.Certainly, CPU also can according to message from queue determine need send to that route mouth.During concrete enforcement, if carry VLAN TAG in message to be sent, then CPU is preferentially identified at according to the VLAN in VLAN TAG the route mouth of searching its correspondence in Port Management table and sends this message to the route mouth found.
S44, send message to the route mouth that finds, flow process terminates.
S45, the route mouth corresponding according to the queue of message place, search primary vlan mark and be added in message from the Port Management table of this route mouth correspondence.
If the message sent to main interface, owing to wherein not carrying VLAN TAG, CPU according to message from queue, determine to need to send this message to that route mouth, and in message, add VLAN TAG, VLAN wherein identifies the primary vlan that can be set in the Port Management table of this route mouth correspondence, and sends this message to the route mouth determined.
S46, to this route mouth send message.
