nullIt should be noted that，Primary nodal point equipment in the application is the host node device (OwnerNode) in ERPS network，Secondary nodal point equipment is neighbor node equipment (NeighborNode) adjacent with described primary nodal point equipment in ERPS network，3rd node device is ordinary node equipment (NormalNode) adjacent with described primary nodal point equipment in ERPS network or interlink node equipment (InterconnectionNode)，Wherein，Looped network protection link RPL is set up between primary nodal point equipment (i.e. host node device) and secondary nodal point equipment (i.e. neighbor node equipment)，Wherein，Primary nodal point equipment、Secondary nodal point equipment、3rd node device be have receive the network switching equipment of sending function，Such as switch、The equipment such as router.
In this application; the outgoing interface of primary nodal point equipment is the interface that may be used for sending message in primary nodal point equipment; further; this interface includes the interface on primary nodal point equipment for being connected with the 3rd node device; also include on primary nodal point equipment for setting up the interface of looped network protection link RPL with secondary nodal point equipment; should be understood that; outgoing interface in the application is the outgoing interface on logical meaning, if having sending function duplexing semiduplex interface may each be outgoing interface (interface) described herein.
In this application, the data message that primary nodal point equipment receives is called the first data message, and the first data message carrying VLANID is called data message to be sent.
Applicants have discovered that, in ERPS network, primary nodal point equipment sends datagram according to example, under example, the link for sending described data message immobilizes, and the looped network protection link RPL that primary nodal point equipment and secondary nodal point equipment room are set up be usually do not send datagram (owing to ERPS network is ring network structure, in order to prevent the data message that primary nodal point equipment sends from being looped back in primary nodal point equipment, therefore primary nodal point equipment and secondary nodal point equipment room are set up looped network protection link RPL is usually and does not send datagram), if the data message sent under certain example is excessive, there will be packet loss or congested situation.
As it is shown in figure 1, the embodiment of the present invention provides a kind of file transmitting method, described method is applied in the primary nodal point equipment of the ERPS network of support virtual LAN VLAN (VirtualLocalAreaNetwork), and described method includes:
Step 101, obtains data message to be sent, and described data message carries VLANID.
Step 102, obtains and compares the link bandwidth surplus that each outgoing interface is corresponding respectively, according to comparative result, it is determined that the first outgoing interface.
Step 103, obtains described VLANID, and described VLANID is corresponding with described first outgoing interface, and is sent from described first outgoing interface by described data message according to this corresponding relation.
In a step 101, primary nodal point equipment using carry VLANID the first data message as data message to be sent, wherein, the first data message that primary nodal point equipment receives just has carried VLANID；If the first data message that primary nodal point equipment receives does not carry VLANID, primary nodal point equipment is the first data message distribution VLANID received, and the VLANID of described distribution is carried in described first data message, and using the first data message of carrying described VLANID as data message to be sent, concrete, the primary nodal point equipment attribute information (address information in data message according to difference the first data message received, Permission Levels etc.) distribute different VLANID for the first different data messages, or primary nodal point equipment is that described the first different data message distributes different VLANID according to the sequencing receiving the first different data messages；As long as data message namely to be sent carries VLANID, to the VLANID then how carried without limitation.
nullIn a step 102，Primary nodal point equipment obtains the link bandwidth surplus that each outgoing interface is corresponding respectively，Wherein，The implication of each outgoing interface includes two or more outgoing interface，Concrete，Obtain the link bandwidth total amount that in each (two or more) outgoing interface, each outgoing interface is corresponding，And obtain the link bandwidth amount that each outgoing interface has currently used，The link bandwidth total amount of each outgoing interface obtained is deducted the current link bandwidth amount used of respectively controlling oneself，Thus calculating the link bandwidth surplus that each outgoing interface is corresponding，Such as，Primary nodal point equipment includes outgoing interface P1、Outgoing interface P2，The link bandwidth total amount that can be obtained outgoing interface P1 by the configuration information of self is 10G，The link bandwidth total amount of outgoing interface P2 is 10G，At a time，Can obtain the outgoing interface P1 link bandwidth amount used by the status information of self is 3G，The link bandwidth amount that outgoing interface P2 has used is 1G，Then the link bandwidth surplus of outgoing interface P1 is 7G (i.e. 10G-3G=7G)，The link bandwidth surplus of outgoing interface P2 is 9G (i.e. 10G-1G=9G)，It should be noted that，Examples detailed above only lists the method for optimizing calculating link bandwidth surplus corresponding to interface，It is not limited to the application，Any link bandwidth surplus that can calculate outgoing interface corresponding is used equally in the application.
In an embodiment of the present invention, link bandwidth surplus corresponding for each outgoing interface obtained is compared by primary nodal point equipment, according to comparative result, chooses the outgoing interface that the link bandwidth surplus of correspondence is maximum, as the first outgoing interface, specifically includes:
If the maximum outgoing interface of the link bandwidth surplus chosen is for some outgoing interface, then determine that some outgoing interface described is described first outgoing interface, such as, if primary nodal point equipment includes outgoing interface P1, outgoing interface P2, tri-outgoing interfaces of outgoing interface P3, and link bandwidth surplus corresponding to three outgoing interfaces is respectively, link bandwidth surplus corresponding for outgoing interface P1 is 1G, link bandwidth surplus corresponding for outgoing interface P2 is 2G, link bandwidth surplus corresponding for outgoing interface P3 is 3G, by relatively, link bandwidth surplus corresponding for outgoing interface P3 is maximum, then determine that interface P3 is the first outgoing interface.
nullIf choosing (the link bandwidth surplus that the above outgoing interface of said two is corresponding respectively is identical) when the maximum outgoing interface of corresponding link bandwidth surplus is two or more outgoing interface，In the plurality of outgoing interface, then determine that an outgoing interface is the first outgoing interface，Such as，If primary nodal point equipment includes outgoing interface P1、Outgoing interface P2、Tri-outgoing interfaces of outgoing interface P3，And link bandwidth surplus corresponding to three outgoing interfaces is respectively，Link bandwidth surplus corresponding for outgoing interface P1 is 3G，Link bandwidth surplus corresponding for outgoing interface P2 is 2G，Link bandwidth surplus corresponding for outgoing interface P3 is 3G，By relatively，Link bandwidth surplus corresponding with outgoing interface P3 for outgoing interface P1 is maximum，From outgoing interface P1 and outgoing interface P3, then determine that an outgoing interface (determining interface P1 or outgoing interface P3) is the first outgoing interface.Again such as, if primary nodal point equipment includes outgoing interface P1, outgoing interface P2, tri-outgoing interfaces of outgoing interface P3, and link bandwidth surplus corresponding to three outgoing interfaces is respectively, link bandwidth surplus corresponding for outgoing interface P1 is 3G, link bandwidth surplus corresponding for outgoing interface P2 is 3G, link bandwidth surplus corresponding for outgoing interface P3 is 3G, namely the link bandwidth surplus that whole outgoing interfaces of primary nodal point equipment are corresponding is all identical, then from outgoing interface P1, outgoing interface P2 and outgoing interface P3 determining, an outgoing interface (determines interface P1, outgoing interface P2 or outgoing interface P3) it is the first outgoing interface.
In an embodiment of the present invention, when primary nodal point equipment determines described first outgoing interface, VLANID in described data message is corresponding with described first outgoing interface, so that described data message is sent from described first outgoing interface by primary nodal point equipment according to this corresponding relation.
Wherein, before the VLANID in described data message is corresponding with described first outgoing interface, primary nodal point equipment obtains the VLANID of described data message.
Wherein, VLANID in described data message is corresponding with described first outgoing interface, so that described data message is sent from described first outgoing interface by primary nodal point equipment according to this corresponding relation described, specifically include, described VLANID is carried out corresponding with described first outgoing interface, the data message with identical VLANID is sent from described first outgoing interface, such as, it is VLAN01 that primary nodal point equipment obtains the VLANID of data message, and the first outgoing interface determined is outgoing interface P1, then the data message carrying VLAN01 is sent by primary nodal point equipment from outgoing interface P1.
Preferably, VLANID and the first outgoing interface is carried out correspondence by primary nodal point equipment, and generates corresponding list item, and described data message, according to this correspondence list item, is sent by primary nodal point equipment from described first outgoing interface.
Preferably, the VLANID corresponding with the first outgoing interface is arranged first timer (if there is corresponding list item, then the VLANID in corresponding list item is arranged first timer), before first timer time-out, if it is identical with the above-mentioned VLANID corresponding with the first outgoing interface that primary nodal point equipment obtains the VLANID that carries of new data message, then described new data message is sent by primary nodal point equipment from the first outgoing interface, otherwise, after first timer time-out, the VLANID having timed out is deleted by primary nodal point equipment from corresponding relation.
Owing to ERPS network is ring network structure, in order to prevent the data message that primary nodal point equipment sends to be looped back in primary nodal point equipment, primary nodal point equipment can set up looped network protection link RPL with secondary nodal point equipment room, characteristic according to RPL, on primary nodal point equipment for set up that the interface of looped network protection link RPL is usually with secondary nodal point equipment will not to secondary nodal point equipment sending data message, when primary nodal point equipment is looped network protection link RPL by the link that the first outgoing interface of determining in step 102 is corresponding, in order to enable described first outgoing interface to secondary nodal point equipment sending data message, primary nodal point equipment needs to change described first outgoing interface attribute, described first outgoing interface is enable to send described data message.
Concrete, when primary nodal point equipment determines the first outgoing interface (this first outgoing interface is set up the interface of looped network protection link RPL with secondary nodal point equipment) by step 102, primary nodal point equipment is corresponding with described first outgoing interface by the VLANID of data message, and the first outgoing interface attribute described in primary nodal point equipment change, allow described first outgoing interface to send to carry the data message of described VLANID (the first outgoing interface after Alternative Attribute is still that the interface for setting up looped network protection link RPL with secondary nodal point equipment, data message for not carrying described VLANID is still in not sending state).
Further, primary nodal point equipment also needs to send, to secondary nodal point equipment and the 3rd node device, the notice message carrying described VLANID, secondary nodal point equipment is made to receive the data message carrying described VLANID according to this notice message, and make the 3rd node device forbid sending the data message carrying described VLANID to described primary nodal point equipment (due to primary nodal point equipment by looped network protection link RPL to secondary nodal point equipment sending data message according to this notice message, in order to prevent the data message that primary nodal point equipment sends from being looped back in this primary nodal point equipment, need to forbid that threeth node device adjacent with this primary nodal point equipment sends described data message to this primary nodal point equipment).Distinguishing in order to convenient, the notice message that primary nodal point equipment is sent in the present embodiment secondary nodal point equipment is called the first notice message, and the notice message that primary nodal point equipment is sent to the 3rd node device is called the second notice message, specific as follows:
nullPrimary nodal point equipment notifies that by carry described VLANID first (this first notice message is protocol massages to message，Such as R-APS protocol massages) it is sent to secondary nodal point equipment，Described secondary nodal point equipment notifies to obtain message VLANID from described first，And according to the described first corresponding information (such as command character) change notified in message receive as described in the interface attributes of the first notice message，Described interface is made to be able to receive that the data message carrying described VLANID，Preferably，When described secondary nodal point equipment receives described first notice message，Corresponding relation can be generated with the interface receiving described first notice message according to the described first VLANID notified in message，So that described secondary nodal point equipment completes the transmitting-receiving of data message according to described corresponding relation and described primary nodal point equipment room.
Primary nodal point equipment notifies that by carry described VLANID second (this second notice message is protocol massages to message, such as R-APS protocol massages) it is sent to the 3rd node device, described 3rd node device notifies to obtain message VLANID from described second, and according to described second notify corresponding information (such as command character) change in message with as described in the interface attributes that is connected of primary nodal point equipment, make the interface being connected with described primary nodal point equipment forbid carrying the data message of described VLANID to the transmission of described primary nodal point equipment.
Further, in order to prevent primary nodal point equipment except sending, from described first outgoing interface, the data message carrying described VLANID, also other outgoing interfaces from primary nodal point equipment also send the data message of described VLANID, and described primary nodal point equipment also forbids that other outgoing interfaces removing described first outgoing interface send the data message carrying described VLANID.
Be can be seen that by above-described embodiment, primary nodal point equipment is when sending datagram, without sending according to example, the link bandwidth surplus that primary nodal point equipment is corresponding by comparing different outgoing interfaces, and according to comparative result, the outgoing interface selecting respective links bandwidth left amount big is used for sending datagram as the first outgoing interface, the link bandwidth surplus that primary nodal point equipment can utilize outgoing interface corresponding is made to select the first outgoing interface sent datagram flexibly, avoid because the link load caused that sends datagram by example is overweight, packet loss or congested situation occur, further, primary nodal point equipment is when sending datagram, dynamic selects the looped network protection link RPL of primary nodal point equipment and secondary nodal point equipment room to send datagram, improve the link circuit resource utilization rate of ERPS network.
nullPresent invention also offers another kind of embodiment，It is specially，Primary nodal point equipment arranges second timer，When primary nodal point equipment is the interface setting up looped network protection link RPL with secondary nodal point equipment by the first outgoing interface that step 102 is determined，Described primary nodal point equipment sends the second notice message to the 3rd node device，And described primary nodal point equipment starts described second timer，If before described second timer time-out，Described primary nodal point equipment receives the feedback message that described 3rd node device sends，Then described primary nodal point equipment determines according to described second, described 3rd node device notifies that message have changed the interface attributes (namely completing the interface making to be connected with described primary nodal point equipment to forbid sending, to described primary nodal point equipment, the data message carrying described VLANID) being connected with described primary nodal point equipment，Described data message is sent to described secondary nodal point equipment from described first outgoing interface by described primary nodal point equipment again.
If after described second timer time-out, described primary nodal point equipment does not receive the feedback message that described 3rd node device sends, then described primary nodal point equipment sends this data message according to example.(in the present embodiment, if primary nodal point equipment is after second timer time-out, do not receive the feedback message that the 3rd node device sends, then it is believed that the 3rd node device be not fully complete the interface attributes that is connected with described primary nodal point equipment of change, namely the 3rd node device still can send, to primary nodal point equipment, the data message carrying described VLANID, if now data message is sent to secondary nodal point equipment from the first outgoing interface by primary nodal point equipment, then this data message sent will loop back in primary nodal point equipment by the 3rd node device, if therefore after this second timer time-out, primary nodal point equipment does not receive the feedback message that described 3rd node device sends, then described primary nodal point equipment sends this data message according to example).
Be can be seen that by above-described embodiment, primary nodal point equipment is by increasing second timer, and before second timer time-out, according to whether receive feedback message that the 3rd node device sends to determine according to described second, whether described 3rd node device notifies that message have changed the interface attributes being connected with primary nodal point equipment, if described primary nodal point equipment determines that described 3rd node device completes change interface attributes, then data message is sent from described first outgoing interface, otherwise data message is sent according to example, avoid because the 3rd node device is not fully complete the change to the interface attributes being connected with primary nodal point equipment, and cause the data message that primary nodal point equipment sends to secondary nodal point equipment, loop back in primary nodal point equipment through the 3rd node device.
For the ease of explanation; embodiments provide an ERPS network scenarios; as shown in Figure 2; in this ERPS network; including primary nodal point device A, secondary nodal point equipment D, the 3rd node device B, wherein, the interface P1 of the outgoing interface P1 of primary nodal point device A and secondary nodal point equipment D sets up looped network protection link RPL; in the prior art, do not send datagram mutually between the outgoing interface P1 and the interface P1 of secondary nodal point equipment of primary nodal point device A.
Wherein, in the present embodiment, for convenience of distinguishing, by primary nodal point device A not data message to be sent in the same time be distinguish between with the second data message, the 3rd data message, the 4th data message respectively.
Based on this ERPS network scenarios, embodiments provide a kind of file transmitting method, as it is shown on figure 3,
Step 201, primary nodal point device A obtains the second data message, and the VLANID carried in described second data message is VLAN10, and described second data message amount of occupied bandwidth is 3G.
Step 202, primary nodal point device A determines the first outgoing interface sending described second data message, specific as follows:
Link bandwidth total amount corresponding respectively for primary nodal point device A acquisition outgoing interface P1 and outgoing interface P2 is 10G, and (namely the link bandwidth total amount of P1-P1 is 10G, the link bandwidth total amount of P1-P2 is 10G), primary nodal point device A obtains, according to the status information of self, the link bandwidth amount that the outgoing interface P1 and outgoing interface P2 of now primary nodal point device A used and is 0G, the then link bandwidth surplus respectively 10G corresponding with outgoing interface P2 for outgoing interface P1 of known primary nodal point equipment, preferably, primary nodal point device A can generate the mapping item of interface and link bandwidth surplus, as shown in table 1:
| OUT-INTERFACE | BANDWIDTH(G) |
| P1 | 10 |
| P2 | 10 |
Table 1
nullNow，It is that the first outgoing interface is for sending the second data message that primary nodal point device A can select interface P1 or outgoing interface P2，Owing to P1-P1 is looped network protection link RPL，Characteristic according to looped network protection link RPL，Outgoing interface P1 will not send the second data message to secondary nodal point equipment D，Therefore can preferably be used for sending described second data message by the link of P2-P1，Namely the outgoing interface P2 of primary nodal point device A is selected (to it should be noted that as the first outgoing interface，Primary nodal point device A also can select interface P1 interface as the first outgoing interface，Concrete grammar is explained in the above-described embodiments，Therefore repeat no more)，After primary nodal point device A is determined and is sent described second data message from outgoing interface P2，And primary nodal point device A to obtain the amount of occupied bandwidth of this second data message from described second data message be 3G，The mapping item of the interface that then primary nodal point device A is previously created and link bandwidth surplus will update，List item after renewal is as shown in table 2:
| OUT-INTERFACE | BANDWIDTH(G) |
| P1 | 10 |
| P2 | 7 |
Table 2
Meanwhile, described primary nodal point device A preferably also can generate the corresponding list item of VLANID and outgoing interface, as shown in table 3:
| VLAN ID | OUT-INTEFACE |
| 10 | P2 |
Table 3
The second data message carrying VLAN10 is sent from interface P2 by primary nodal point device A according to table 3.
Step 203, at subsequent time, primary nodal point device A obtains the 3rd data message, and determines the first outgoing interface sending described 3rd data message, specific as follows:
nullPrimary nodal point device A obtains the 3rd data message，The VLANID carried in described 3rd data message is VLAN20，And described 3rd data message amount of occupied bandwidth is 2G，According to the table 2 that primary nodal point device A in step 202 generates，The link bandwidth surplus that corresponding with outgoing interface P2 for the outgoing interface P1 link bandwidth surplus of current primary nodal point device A is respectively corresponding for outgoing interface P1 is 10G，Link bandwidth surplus corresponding for outgoing interface P2 be 7G (in other embodiments，Primary nodal point device A can according to the method in step 202，Redefine the link bandwidth surplus of each outgoing interface)，The link bandwidth surplus of primary nodal point device A more described outgoing interface P1 and outgoing interface P2，Comparative result is the link bandwidth surplus of the outgoing interface P1 of the primary nodal point device A link bandwidth surplus more than outgoing interface P2，Then described primary nodal point device A is according to this comparative result，Select interface P1 and send described 3rd data message (now as the first outgoing interface，First outgoing interface is the interface that looped network protection link RPL is corresponding，The method sending the 3rd data message is illustrated in previous embodiment，Therefore repeat no more)，Preferably，Primary nodal point device A updates the table 2 in step 202，Concrete as shown in table 4:
Table 4
Meanwhile, the VLANID generated in step 202 preferably can be updated (also can regenerate) with the corresponding list item (table 3 in step 202) of outgoing interface by described primary nodal point device A, and the list item after renewal is as shown in table 5:
| VLAN ID | OUT-INTEFACE |
| 10 | P2 |
| 20 | P1 |
Table 5
The 3rd data message carrying VLAN20 is sent from outgoing interface P1 by primary nodal point device A according to this table 5.
It should be noted that, although above-described embodiment only has outgoing interface P1, outgoing interface P2 to illustrate with primary nodal point device A, but it is not limiting as primary nodal point device A and only has two outgoing interfaces, when primary nodal point device A exists plural outgoing interface, still it is suitable for technical scheme provided herein.
nullBe can be seen that by above-described embodiment，Primary nodal point device A is when sending datagram (the second data message and/or the 3rd data message)，Without sending according to example，The link bandwidth surplus that primary nodal point device A is corresponding by comparing different outgoing interfaces，And according to comparative result，Determine the first outgoing interface for sending datagram，The link bandwidth surplus that primary nodal point device A can utilize outgoing interface corresponding is made to select the first outgoing interface sent datagram flexibly，Avoid because the link load caused that sends datagram by example is overweight，Packet loss or congested situation occur，Further，Primary nodal point equipment is when sending datagram，Dynamic selects the looped network protection link RPL of primary nodal point equipment and secondary nodal point equipment room to send datagram，Improve the link circuit resource utilization rate of ERPS network.
Based on above-described embodiment, present invention also offers a kind of preferred version, the program includes, VLANID in the corresponding list item generate primary nodal point equipment in above-described embodiment arranges first timer, when before described first timer time-out, if the VLANID that the 4th data message that primary nodal point equipment need to send carries is identical with the VLANID in corresponding list item, then primary nodal point equipment is according to this correspondence list item, described 4th data message is sent from the first outgoing interface, otherwise when after described first timer time-out, VLANID corresponding to the first timer having timed out is deleted by primary nodal point equipment.
For convenience of description, illustrate with the table 5 of above-described embodiment, by table 5, at present, the second data message carrying VLAN10 sends from the outgoing interface P2 of primary nodal point equipment, the 3rd data message carrying VLAN20 sends from the outgoing interface P1 of primary nodal point equipment, and the VLANID in his-and-hers watches 5 arranges the first timer that time-out time is 10 seconds, as shown in table 6:
| VLAN ID | OUT-INTEFACE | VLAN ID TIME(S) |
| 10 | P2 | 10 |
| 20 | P1 | 10 |
Table 6
Subsequent time, after the second data message carrying VLAN10 is sent completely by the outgoing interface P2 of primary nodal point equipment, start this first timer, if before this first timer time-out, the VLAN id number that primary nodal point equipment acquisition the 4th data message carries is VLAN10, then the 4th data message is sent (now can again refresh time-out time corresponding for VLAN10 table 6) from outgoing interface P2 by primary nodal point equipment.
Be can be seen that by the present embodiment, when before first timer time-out, if the VLANID entrained by new data message that primary nodal point equipment obtains is identical with the VLANID in corresponding list item, described new data message can directly be sent from the first outgoing interface by primary nodal point equipment according to described corresponding list item, without redefining the first outgoing interface again, save primary nodal point equipment and send the time of described new data message.
Or, subsequent time, after the second data message carrying VLAN10 is sent completely by the outgoing interface P2 of primary nodal point equipment, start this first timer, if before this first timer time-out, primary nodal point equipment does not carry the data message of VLAN10, then, after this first timer time-out, VLAN10 in table 6 is deleted.
