The third modification: for controller maintenance port aggregation group inner port member's change, increase configuration messages, for controller all bosom friend change planes some outbound ports formed to port trunking groups, delete port trunking group, in designated port aggregation group, increase or deletion port member designated port aggregation group inner port member's message repeating ratio.
Referring to Fig. 1, be an embodiment flow chart of message transmission control method of the present invention, this embodiment is applied on the controller in SDN, comprises the following steps:
Step 101: for message flow generates many forward-paths.
Switch in SDN receives reporting for the first time during literary composition of certain message flow, due to the forwarding strategy of this message flow not also on switch, therefore the literary composition of reporting for the first time of this message flow is sent to controller, so that to the forwarding strategy of this message flow of controller request, this forwarding strategy can be carried in the stream list item that controller issues to switch conventionally.
After SDN sets up, controller is learnt the network topology structure of this SDN, obtain the port information of respective switch in SDN, and the annexation between port etc., therefore when controller receives reporting for the first time after literary composition of this message flow that switch reports, obtain this report for the first time civilian source address and destination address, according to the SDN network topology of having obtained, for this message flow generates many forward-paths from source address to destination address, the generation of many forward-paths can adopt various computational methods of the prior art, such as shortest path computational methods etc., this the present embodiment is repeated no more.
Step 102: the port trunking group that the different outbound ports that belong to same switch on many forward-paths is configured to this switch.
In the present embodiment, controller is generating after many forward-paths for message flow, can obtain the outbound port of each switch on many forward-paths, and the outbound port being positioned on many forward-paths that belongs to same switch is formed to port trunking group, so that switch can E-Packet by a plurality of outbound ports in this port trunking group; For only comprising the switch of an outbound port on many forward-paths, this switch E-Packets by this outbound port.
Step 103: issue the configuration information of port trunking group to switch, so that this switch while receiving message, forwards this message by the outbound port in port trunking group.
In the present embodiment, in the configuration information of port trunking group, at least comprise the port-mark of a plurality of outbound ports, further can also be included as the message repeating ratio that each outbound port arranges, in the stream list item issuing to switch at controller, the outbound port of stream list item is appointed as to this port trunking group, so that switch is by the stream that E-Packets of the outbound port in port trunking group.Wherein, when message repeating ratio being set for each outbound port, can message repeating ratio be set for this outbound port according to the effective bandwidth of outbound port, effective bandwidth refers to that this outbound port forwards the idle bandwidth sum of the shared bandwidth of this message and this outbound port.
In one implementation, controller can be according to the configuration information in the port trunking group of switch, for switch generates the group table (Group Table) that comprises a plurality of outbound ports, this group table is handed down to switch by control message, and the message outbound port of stream list item is pointed to this group table, so that switch E-Packets by a plurality of outbound ports in this group table.This Time Controller can utilize the OFTP_SET_CONFIG configuration messages in OpenFlow agreement to issue group table to switch, wherein, for the newly-increased type of message OFPC_TRUNK_SET of this configuration messages, OFPC_TRUNK_SET is for the outbound port sign in notification controller group table, the message repeating ratio of outbound port, corresponding message field is as follows:
Unit16_t trunk_id; For representing the ID of port trunking group;
Unit16_t trunk_mem; For representing the outbound port in port trunking group;
Unit16_t trunk_ration; For representing the message repeating ratio of outbound port in port trunking group:
Accordingly, issuing stream during list item, specifying outbound port to show for this group, the field now flowing in the type of action Struct ofp_action_output of list item is as follows:
Uint16_t type; Be used for representing that type of action is outbound port sensing group table;
Uint16_len; For representing the length of action;
Uint16_t?trunk；
In another kind of implementation, controller also can be integrated in configuration information in stream list item and issue:
The message repeating ratio of outbound port and each outbound port to be in stream list item, directly specified, following type of action can be in stream list item, increased newly:
Struct?ofp_action_outputSDN{
Uint16_t type; For representing that type of action is a SDNtrunk who newly increases, comprise that outbound port is port list, and the message repeating ratio of each outbound port;
Uint16_t len; Be used for representing to move length;
Uint16_t portmem; Be used for explaining outbound port number;
Struct ofp_sdntrunk portmap[0]; For representing the first address of port list;
}
Wherein, the information exchange of each outbound port in port list is crossed following field and is represented:
Struct?opf_action_output_trunkport{
Uint16_t port; For expressing the port numbers of port;
Uint16_t ratio; For expressing the message repeating ratio of port;
}
It should be noted that, above-mentioned two kinds of implementations are to the expansion of OpenFlow agreement and supplement, also can not revise OpenFlow agreement in actual applications, but by realizing issuing of configuration information with controller and the mutual upper layer software (applications) of switch, when controller is confirmed after the configuration of port trunking group, this configuration notification, to softwares such as NetConf (network configuration), webmasters, is handed down to corresponding switch by these softwares by the configuration information of port trunking group.
Follow-up, when switch receives message, the message that can will forward for each outbound port distribution according to the message repeating ratio of each outbound port in port trunking group, and forward the message distributing.When switch receives message, first based on message attribute, calculate cryptographic Hash, described message attribute can be one or more the combination such as source address, protocol type, affiliated VPN (virtual private network) (Virtual Private Network, VPN), and the present invention does not limit.After obtaining cryptographic Hash, by Hash mapping table, determine the outbound port that cryptographic Hash is corresponding, by determined outbound port, E-Packet.
Supposing has three outbound ports in port trunking group, be respectively port1, port2 and port3, the situation of message repeating ratio is not set for outbound port in port trunking group, the message repeating ratio of three outbound ports of acquiescence is respectively 1:1:1, the corresponding cryptographic Hash of each outbound port, correspondingly set up Hash mapping table as shown in table 1 below:
Table 1
| Cryptographic Hash | Outbound port |
| 0 | Port1 |
| 1 | Port2 |
| 2 | Port3 |
If the message repeating ratio of three outbound ports is respectively 1:2:1, according to the cryptographic Hash of the corresponding varying number of the different outbound ports of message repeating ratio setting, the forwarding ratio that is port1 and port3 is 1, distinguish a corresponding cryptographic Hash, and the message repeating ratio of port2 is 2, corresponding two cryptographic Hash, the Hash mapping table of being set up as following table 2:
Table 2
| Cryptographic Hash | Outbound port |
| 0 | Port1 |
| 1 | Port2 |
| 2 | Port3 |
| 3 | Port2 |
Optionally, the embodiment of the present invention can be safeguarded port aggregation group by following any one mode:
The situation that the first maintenance mode corresponding ports aggregation group inner port is deleted: when the link at the first port place disconnects in port trunking group, during the first port down, switch can be deleted the first port in port trunking group in this locality, now switch is if the stream that E-Packets, and the message repeating ratio that can configure according to remaining port in port trunking group forwards the message receiving; Simultaneously, switch can be to controller report port exit message, controller is known after the first port down, the first port in port trunking group can be deleted, and issue the first port aggregation group change message to described switch, subsequent control device can relearn the network topology of SDN, upgrades the configuration information of port trunking group, and issue the configuration information after renewal to switch according to learning outcome.
The situation that the second maintenance mode corresponding ports aggregation group inner port increases: while increasing the second port for E-Packeting on switch, the port that desampler reports adds message, according to port, add message that the second port is added to port trunking group, and issue the second port trunking group change message to switch, so that switch adds port trunking group according to the second port trunking group change message by the second port.
The situation that the third maintenance mode corresponding ports aggregation group is deleted: when monitoring control devices is when only comprising an outbound port in port trunking group, delete this port trunking group, and issue port trunking group deletion message to switch, so that switch is deleted message according to port trunking group, delete this port trunking group, and the outbound port of message is appointed as to this remaining outbound port.Controller can increase type of message OFPC_TRUNK_DEL in OFTP_SET_CONFIG configuration messages, and in the field Unit16_t of this type of message trunk_id, carries the ID of the port trunking group that will delete.
The 4th kind of corresponding situation of adjusting the message repeating ratio of outbound port in port trunking group of maintenance mode: when maintenance packet forwards ratio, controller can real-time collecting port trunking group in the flow information of each outbound port, according to this flow information, determine in real time the effective bandwidth of port, so that when effective bandwidth changes, according to the effective bandwidth after changing, adjust the message repeating ratio of outbound port in port trunking group, thereby utilize better the network bandwidth, avoid network congestion.For example, in port trunking group on the forward-path of message flow 1 correspondence, there are two outbound ports, are respectively outbound port A and outbound port B, when the effective bandwidth of outbound port A is 1G, when the effective bandwidth of outbound port B is 2G, the message repeating ratio that can set out port A and outbound port B is 1:2; And the effective bandwidth that outbound port B detected when controller is while becoming 1G, the message repeating ratio of capable of regulating outbound port A and outbound port B is 1:1, thereby avoids the flow congestion of outbound port B.When adjusting message repeating ratio, controller can use aforementioned messages type OFPC_TRUNK_SET, and the port numbers of carrying the outbound port that need to adjust message repeating ratio in the Unit16_t of this type of message trunk_mem field, and in Unit16_t trunk_ration field, carry the message repeating ratio after adjustment.
As seen from the above-described embodiment, controller in SDN is that the switch E-Packeting generates port trunking group, when controller issues after the configuration information of port trunking group to switch, switch can forward the message from source address to destination address by a plurality of outbound ports in port trunking group simultaneously, thereby make the message flow can be by port trunking group load balancing to a plurality of paths, avoid the link congestion in network, effectively improved the utilance of the network bandwidth.
Referring to Fig. 2, be another embodiment flow chart of message transmission control method of the present invention, this embodiment is applied on the switch in SDN, comprises the following steps:
Step 201: the configuration information of the port trunking group that reception controller issues, this port trunking group is that controller is that message flow generates after many forward-paths, according to belonging to the port trunking group of the different outbound ports of this switch for this switch configuration on many forward-paths.
In the present embodiment, in the configuration information of port trunking group, at least comprise the port-mark of a plurality of outbound ports, further can also be included as the message repeating ratio that each outbound port arranges.
When the configuration information of receiving port aggregation group, switch can receive respectively the control message of the configuration information that comprises this port trunking group that controller issues, and for forwarding the stream list item of stating message, wherein, the message outbound port of stream list item is appointed as described port trunking group; Or switch also can only receive the stream list item for E-Packeting that controller issues, wherein, in this stream list item, added the configuration information of port trunking group, and the message outbound port of stream list item is appointed as this port trunking group.
In addition, for controller, to switch, issue the situation of control message, controller also can be according to the configuration information in the port trunking group of switch, for this switch generates the group table (Group Table) that comprises a plurality of outbound ports, this group table is handed down to switch by control message, and the message outbound port of stream list item is pointed to this group table, to realize switch, by a plurality of outbound ports in this group table, E-Packet.
Step 202: when receiving the message of message flow, this message is forwarded by the outbound port in port trunking group.
When switch receives message, can be the corresponding stream of this message coupling list item, and according to the appointment outbound port of message in this stream list item, i.e. a plurality of outbound ports in port trunking group forward message; Further, when each outbound port has configured message repeating ratio, can, before E-Packeting by a plurality of outbound ports, according to message repeating ratio, to each outbound port in port trunking group, distribute the message that will forward.
As seen from the above-described embodiment, controller in SDN is that the switch E-Packeting generates port trunking group, when controller issues after the configuration information of port trunking group to switch, switch can forward the message from source address to destination address by a plurality of outbound ports in port trunking group simultaneously, thereby make the message flow can be by port trunking group load balancing to a plurality of paths, avoid the link congestion in network, effectively improved the utilance of the network bandwidth.
Referring to Fig. 3, be the applied SDN configuration diagram of the embodiment of the present invention:
In SDN framework shown in Fig. 3, comprise a controller 20, switch 21 is to switch 29, and source terminal 30 and object terminal 31.Wherein, controller 20 is directly connected with switch 21, and other switch 22 is realized network by network topology with controller 20 to switch 29 and is connected.It should be noted that, only show a kind of networking mode in Fig. 3, in actual networking, controller also can directly be connected with each switch in network, and this embodiment of the present invention is not limited.
In the present embodiment, suppose that message is transferred to object terminal 31 from source terminal 30, the port that comprises a plurality of message transmissions on each switch, these ports are divided into inbound port and outbound port according to message transmissions direction, for example, the inbound port 231 that comprises message transmission on switch 23, and outbound port 234.
Referring to Fig. 4, be another embodiment flow chart of message transmission control method of the present invention, this embodiment is described in conjunction with the SDN framework shown in Fig. 3:
Step 401: when controller receives reporting for the first time during literary composition of message flow, obtain report for the first time civilian source address and destination address.
In conjunction with Fig. 3, suppose that source terminal 30 will be to object terminal 31 message transmission streams, the source address of this message flow is the address " 1.1.1.1 " of source terminal 30, destination address is the address " 2.2.2.2 " of object terminal 31.Source terminal 30 is transferred to switch 22 by the literary composition of reporting for the first time of this message flow, the forwarding strategy of this message not on switch 22, therefore the literary composition of reporting for the first time of this message flow is uploaded to controller 20 by switch 21, controller obtains source address " 1.1.1.1 " and the destination address " 2.2.2.2 " carrying in this literary composition of reporting for the first time.
Step 402: controller is according to the port annexation of switch in SDN, for message flow generates many forward-paths from source address to destination address.
In the present embodiment, suppose that controller 20 is according to the port annexation of switch in SDN, for message flow has generated four forward-paths from source terminal 30 and object terminal 31, be respectively:
Link 1: switch 22 (inbound port 233, outbound port 222)-> switch 21 (inbound port 211, outbound port 214)-> switch 25 (inbound port 255, outbound port 252)-> switch 27 (inbound port 273, outbound port 274)-> switch 26 (inbound port 262, outbound port 263);
Link 2: switch 22 (inbound port 233, outbound port 222)-> switch 21 (inbound port 211, outbound port 213)-> switch 25 (inbound port 251, outbound port 252)-> switch 27 (inbound port 273, outbound port 274)-> switch 26 (inbound port 262, outbound port 263);
Link 3: switch 22 (inbound port 233, outbound port 221)-> switch 23 (inbound port 231, outbound port 234)-> switch 25 (inbound port 254, outbound port 252)-> switch 27 (inbound port 273, outbound port 274)-> switch 26 (inbound port 262, outbound port 263);
Link 4: switch 22 (inbound port 233, outbound port 221)-> switch 23 (inbound port 231, outbound port 234)-> switch 25 (inbound port 254, outbound port 253)-> switch 28 (inbound port 281, outbound port 282)-> switch 26 (inbound port 261, outbound port 263).
Step 403: controller obtains the outbound port of each switch on many forward-paths.
Four forward-paths of controller based on aforementioned generation, obtain the outbound port that each switch on these four forward-paths comprises, and obtain result as shown in table 3 below:
Table 3
| Switch identification | Outbound port sign |
| Switch 21 | Outbound port 213, outbound port 214 |
| Switch 22 | Outbound port 221, outbound port 222 |
| Switch 23 | Outbound port 234 |
| Switch 25 | Outbound port 252, outbound port 253 |
| Switch 26 | Outbound port 263 |
| Switch 27 | Outbound port 274 |
| Switch 28 | Outbound port 282 |
Step 404: controller is that the switch that comprises a plurality of outbound ports on many forward-paths generates the port trunking group being comprised of a plurality of outbound ports.
Based on aforementioned table 3, controller is that switch 22 generates port trunking group 1, comprises outbound port 221 and outbound port 222 in port trunking group 1; For switch 21 generates port trunking group 2, in port trunking group 2, comprise outbound port 213 and outbound port 214; For switch 25 generates port trunking group 3, in port trunking group 3, comprise outbound port 252 and outbound port 253.As shown in Figure 3, ellipticity tables has illustrated above-mentioned three port trunking groups by a dotted line respectively.
Step 405: controller is that each outbound port in port trunking group arranges message repeating ratio.
In the present embodiment, controller is when the outbound port in each port trunking group arranges message repeating ratio, can calculate this message repeating ratio according to the effective bandwidth of each outbound port, take port trunking group 2 as example, the effective bandwidth of supposing outbound port 214 places is 20G, the effective bandwidth of outbound port 213 is 10G, therefore can set out port 214 is 2:1 with the message repeating ratio of outbound port 213, so that switch 21 receives after message, outbound port 214 and outbound port 213 proportionally 2:1 carry out load balancing forwarding to message.
Step 406: issue stream list item to switch, in this stream list item, added the configuration information of port trunking group, and the message outbound port of stream list item is appointed as this port trunking group, and configuration information comprises the outbound port in port trunking group, and the message repeating ratio of each outbound port.
Controller, after being the complete port trunking group of switch configuration, for switch generates the stream list item for E-Packeting, and issues corresponding stream list item to each switch.Wherein, the message matching field of stream in list item can be source address and the destination address of this message, or the information that other can this message of unique identification; Message outbound port field can be added the configuration information of this port trunking group, comprises the outbound port sign in port trunking group, and message repeating ratio corresponding to each outbound port.
Step 407: when switch receives message, for this message mates corresponding stream list item.
When switch receives message, if the matching field of message is source address and destination address in stream list item, switch can be identified source address and the destination address of this message, and according to this source address and destination address, mates the stream list item of this message; Or if the matching field of message is other message informations in stream list item, switch can identify the message information for mating from the header packet information of message, and mates the stream list item of this message according to this message information.The process of the upper message coupling of above-mentioned switch stream list item is consistent with existing matching process, does not repeat them here.
Step 408: this message is forwarded to the message that wherein each outbound port will forward according to message repeating pro rate by the outbound port in the port trunking group of appointment in stream list item.
Known in conjunction with Fig. 3, message is being transferred to the process of object terminal 31 from source terminal 30, the switch that comprises port trunking group of take is example, first message is transferred to switch 22 from source terminal 30, by switch 22, by the outbound port 221 in port trunking group 1 and outbound port 222, is forwarded to respectively on switch 23 and switch 21; In like manner, switch 21 is forwarded to switch 25 by the message receiving by the outbound port 214 in port trunking group 2 and outbound port 213, and switch 25 is forwarded to respectively switch 28 and switch 27 by the message receiving by the outbound port 253 in port trunking group 3 and outbound port 252.By above-mentioned transmitting procedure, can be so that the message from source address 1.1.1.1 to destination address 2.2.2.2 can be realized load balancing at many forward-paths.
As seen from the above-described embodiment, controller in SDN is that the switch E-Packeting generates port trunking group, when controller issues after the configuration information of port trunking group to switch, switch can forward the message from source address to destination address by a plurality of outbound ports in port trunking group simultaneously, thereby make the message flow can be by port trunking group load balancing to a plurality of paths, avoid the link congestion in network, effectively improved the utilance of the network bandwidth.
