Based on the network architecture shown in Fig. 1, a kind of method embodiments providing Bandwidth adjustment, as in figure 2 it is shown, described method includes:
201, when detecting that the first binding group link quantity changes, the first equipment obtains the current ink quantity of the first binding group.
Described first equipment can be the router 1 in Fig. 1, and corresponding first binding group is the binding group 1 in Fig. 1.Additionally, described first equipment can also be the router 2 in Fig. 1, corresponding first binding group is the binding group 2 in Fig. 1.Illustrating as a example by first equipment router 1 as access base station in the embodiment of the present invention, corresponding second equipment is the router 2 of access base station controller.It will be appreciated that equipment is carried out the differentiation of the one the second only for ease of describing, it is not intended as the restriction to the embodiment of the present invention.
First binding group is connected with the first equipment, for being connected in the first equipment base station.Generally, the first binding group can be converged by 16 to 32 multilink bundlings and form, and is not defined the concrete number of links of the first binding group in the embodiment of the present invention.
When the first equipment Inspection to the first binding group link quantity changes, obtain the current ink quantity of the first binding group, described current ink quantity change by the first binding group link quantity after the number of links that comprised of the first binding group.First binding group link quantity changes and specifically includes: the number of links caused cannot be used to reduce owing to some link breaks down, or, increase owing to faulty link recovers the available number of links caused.Described in the embodiment of the present invention or the current ink quantity of similar described the first binding group refers to number of links that is available in the first binding group and that be being currently used, this number of links is not more than the link total quantity in the first binding group.Link in binding group can be divided three classes link according to use state: 1) the unavailable link of fault, 2) link that is available and that be being currently used, 3) available but not currently used link.Current ink quantity described in the embodiment of the present invention is link that is available and that be being currently used.
202, the first equipment generates instruction message, adds number of links change instruction and the current ink quantity of the first binding group in this instruction message.
This instruction message adjusts the number of links of the second binding group for instruction the second equipment according to the current ink quantity of the first binding group.The number of links of described adjustment the second binding group is that the current ink quantity to the second binding group increases and decreases, so that the current ink quantity of the second binding group is equal with the current ink quantity of the first binding group.
Described instruction message can be privately owned message can also be exclusive message based on bearer network transmission means, type of message and message format are not limited by the present invention.
203, the instruction message of generation is sent to the second equipment by the first equipment.
The instruction message of generation is sent to the second equipment by the first equipment, in order to the second equipment adjusts the number of links in the second binding group according to this instruction message.Described second binding group is connected with the second equipment.In FIG, the second equipment is router 2, and corresponding second binding group is binding group 2.
Instruction message, after receiving instruction message, is first identified by the second equipment according to the number of links change instruction carried in instruction message, and identifying this instruction message is that link change notifies message.Then the current ink quantity of the first binding group that the second equipment carries in obtaining instruction message, and compare with the current ink quantity of the second binding group.If the current ink quantity of the first binding group and the second binding group is equal, then the current ink quantity of the second binding group is not adjusted by the second equipment；If the current ink quantity of the first binding group is more than the current ink quantity of the second binding group, then the second equipment is by a plurality of link activation to be activated, thus the current ink quantity of the second binding group increases to the quantity equal with the current ink quantity of the first binding group；If the current ink quantity of the first binding group is less than the current ink quantity of the second binding group, the then link down that the second equipment will have more than the first binding group in the second binding group.Thus the first binding group is adjusted consistent with the number of links of the second binding group.
In prior art, when the number of links in binding group 1 changes, the current ink quantity of binding group 1 after change is reported upper strata gateway device by router 1, network manager obtains the current ink quantity after change in binding group 1, the current ink quantity then manually adjusting in binding group 2 according to the current ink quantity tied up in group 1.Owing to artificial reaction can not reach the other response speed of communication stage, and Network Management Equipment to base station or base station controller physical distance farther out, so the time cycle of Bandwidth adjustment is longer.
The method of the Bandwidth adjustment of the embodiment of the present invention, instruction message can be sent by the first equipment to the second equipment when the current ink quantity of the first binding group changes, in this instruction message, carry the number of links change changed for identifying number of links indicate and the current ink quantity of the first binding group after change, so that the second equipment according to this instruction message the current ink quantity of the second binding group is adjusted to change after the identical quantity of the current ink quantity of the first binding group, thus by consistent for the Bandwidth adjustment of the first equipment and the second equipment two ends.Owing to the notification message of the first binding group current ink number change is sent to the second equipment by the first equipment with the form of message, so compared with the current ink quantity manually adjusting the second binding group in prior art, second equipment of can saving adjusts the time of bandwidth, eliminates the impact on carrier class quality of service of the Bandwidth adjustment overlong time.
The embodiment of the present invention additionally provides the method for another kind of Bandwidth adjustment, as it is shown on figure 3, described method includes:
301, the second equipment receives instruction message and/or the confirmation message that the first equipment sends.
When the first equipment can be the router 1 in Fig. 1, described second equipment is the router 2 in Fig. 2, and accordingly, the second binding group is binding group 2.With first equipment router the 1, second equipment as access base station for illustrating as a example by the router 2 of access base station controller in the embodiment of the present invention.It will be appreciated that equipment is carried out the differentiation of the one the second only for ease of describing, it is not intended as the restriction to the embodiment of the present invention.
Second binding group is connected with the second equipment, for being connected in the second equipment by base station controller.Generally, the second binding group can be converged by 16 to 32 multilink bundlings and form, and is not defined the concrete number of links of the second binding group in the embodiment of the present invention.
When the first equipment Inspection to the first binding group link quantity changes, instruction message or confirmation message, the current ink quantity of the first binding group after carrying change in this instruction message or confirmation message can be sent to the second equipment.Described instruction message or described confirmation message adjust the number of links in the second binding group for instruction the second equipment according to the current ink quantity of the first binding group after change.In the embodiment of the present invention, the number of links of described adjustment the second binding group is that the current ink quantity to the second binding group increases and decreases, so that the current ink quantity of the second binding group is equal with the current ink quantity of the first binding group after change.
In the embodiment of the present invention, described instruction message or described confirmation message can be privately owned message can also be exclusive message based on bearer network transmission means, type of message and message format are not limited by the present invention.
302, the current ink quantity of the first binding group during the second equipment obtains instruction message or confirmation message.
Receive as a example by the instruction message that the first equipment sends by the second equipment: the second equipment, after receiving the instruction message that the first equipment sends, identifies this instruction message for indicating the number of links of the first binding group to there occurs change according to the number of links change instruction in instruction message.Second equipment obtains the current ink quantity of the first binding group carried in instruction message.
After the second equipment receives the confirmation message that the first equipment sends, according to the number of links in confirmation message, the second equipment confirms that instruction identifies this confirmation message for indicating the number of links of the first binding group to there occurs change.Second equipment obtains the current ink quantity of the first binding group carried in confirmation message.
303, the second equipment determines that the current ink quantity of the first binding group is the most equal with the current ink quantity of the second binding group.
The current ink quantity of the first binding group after wherein the current ink quantity of the first binding group is change, the current ink quantity of the first binding group that the i.e. second equipment obtains from instruction message or confirmation message.The current ink quantity of the first binding group and the current ink quantity of the second binding group are compared by the second equipment, it follows that the former is greater than, equal to being also less than the latter, in this, as the adjustment foundation of 304.
304, the second equipment is according to determining that result adjusts the current ink quantity of the second binding group, makes the current ink quantity in the second binding group and described first binding group equal.
Concrete, when after change, the current ink quantity of the first binding group is equal to the current ink quantity of the second binding group, the second equipment abandons instruction message or confirmation message, then carries out proper communication with the first equipment.When after change, the current ink quantity of the first binding group is less than the current ink quantity of the second binding group, the link that second equipment Removal the second binding group has more than the first binding group.Such as, if the current ink quantity of the first binding group is 12 after Bian Hua, the current ink quantity of the second binding group is 16, then 4 links in second equipment Removal the second binding group.When after change, the current ink quantity of the first binding group is more than the current ink quantity of the second binding group, second equipment calculates the first binding group current ink quantity and the difference of the second binding group current ink quantity after change, activates the link to be activated of difference quantities in the second binding group.Such as, if the current ink quantity of the first binding group is 16 after Bian Hua, the current ink quantity of the second binding group is 12, then the second equipment calculates both differences is 4, and the second device activation 4 link, so that the current ink quantity of the second binding group becomes 16.Thus the first binding group is adjusted consistent with the number of links of the second binding group.
It should be noted that link in binding group can be divided three classes link according to use state: 1) the unavailable link of fault, 2) the available and link that is being currently used, 3) available but not currently used link.Current ink quantity described in the embodiment of the present invention is link that is available and that be being currently used, and the link of the second device activation is available but not currently used link.Second equipment will can use but after not currently used link activation, and this link becomes link that is available and that be being currently used.
In prior art, when the number of links in binding group 1 changes, the current ink quantity of binding group 1 after change is reported upper strata gateway device by router 1, network manager obtains the current ink quantity after change in binding group 1, the current ink quantity then manually adjusting in binding group 2 according to the current ink quantity tied up in group 1.Owing to artificial reaction can not reach the other response speed of communication stage, and Network Management Equipment to base station or base station controller physical distance farther out, so the time cycle of Bandwidth adjustment is longer.
The method of the Bandwidth adjustment of the embodiment of the present invention, second equipment can be after the instruction message receiving the first equipment transmission or confirmation message, number of links change instruction or number of links according to carrying in this instruction message or confirmation message confirm that instruction recognizes the first binding group current ink quantity and changes, then the current ink quantity of the first binding group after the change that acquisition is carried in indicating message or confirmation message, according to this instruction message the current ink quantity of the second binding group is adjusted to change after the equal quantity of the current ink quantity of the first binding group, thus by consistent for the Bandwidth adjustment of the first equipment and the second equipment two ends.Owing to the second equipment receives the notification message of the first binding group current ink number change with the form of message, and the current ink quantity of the second binding group is automatically adjusted according to this notification message, so compared with the current ink quantity manually adjusting the second binding group in prior art, second equipment of can saving adjusts the time of bandwidth, eliminates the impact on carrier class quality of service of the Bandwidth adjustment overlong time.
In the embodiment shown in Fig. 2 and Fig. 3; link in binding group includes but are not limited to be the E1 link of E1 link or CPOS channelizing; generally pool binding group by E1 multilink bundling between base station and router, between base station controller and router, pool binding group by the E1 multilink bundling of CPOS channelizing.In the embodiment of the present invention, binding group includes but are not limited to be MLPPP binding group or IMA binding group.
nullIn the embodiment shown in Fig. 2 and Fig. 3，Base station and base station controller can access in multiple bearer network，Pseudo wire emulation (the Pseudo-WireEmulationEdgetoEdge of the follow-up edge-to-edge with L2VPN of the present invention，It is called for short PWE3) illustrate as a example by the bearer network that accesses as base station and base station controller of network，And the step in the embodiment of the present invention and parameter are extended and describe in detail by the feature in conjunction with PWE3 network，Will be clear that，Using PWE3 network as one of bearer network possible implementation of one being only the embodiment of the present invention，In actual application，For other kinds of bearer network，Those skilled in the art can be in conjunction with the implementation using PWE3 network as bearer network the species characteristics combining other kind bearer networks，Bandwidth adjustment is realized on the premise of not paying creative work.Bandwidth adjustment modes based on other kind bearer networks are not enumerated by the embodiment of the present invention one by one.
First, as further expanding the embodiment shown in Fig. 2 of the present invention, before step 201, when the first equipment is when being connected in PWE3 network, first equipment generates confirmation message, adds the current ink quantity of the first binding group when number of links confirms instruction and initializes at this confirmation message.Then the first equipment will confirm that message is sent to the second equipment.
Alternatively, during for avoiding initializing, network transmission instability causes the second equipment to miss confirmation message, first equipment can repeatedly send confirmation message according to predetermined period to the second equipment, and the such as first equipment sends a confirmation message every 3ms (millisecond) to the second equipment and continuously transmits 3 times.
Being similar to, the second equipment can also generate confirmation message, and the current ink quantity of the first binding group when initializing is sent to the first equipment, the number of links that when consulting to determine initialization with the first equipment, the first binding group uses with the second binding group.
Alternatively, during for avoiding initializing, network transmission instability causes the first equipment to miss confirmation message, second equipment can also repeatedly send confirmation message according to predetermined period to the first equipment, and the such as second equipment sends a confirmation message every 3ms (millisecond) to the first equipment and continuously transmits 3 times.
First equipment and the second equipment are consulted to determine a smallest link coupling numerical value, the number of links that when this numerical value is to initialize, in the first binding group and the second binding group, current ink quantity is less.Such as, during initialization, the current ink quantity of the first binding group is 12, the current ink quantity of the second binding group is 16, then the first equipment and the second equipment are consulted to show that a smallest link coupling numerical value is 12, the a fairly large number of side of binding group current ink (the second equipment) removes 4 links, the current ink quantity making front second binding group becomes 12, thus completes the initialization of number of links.
After completing number of links initialization, the first equipment quilt and the second equipment carry out proper communication.When the first device link quantity changes, the first equipment order performs step 201 in Fig. 2 and, to step 203, notifies the number of links of the first binding group after change to the second equipment.Further, further expand as to the embodiment of the present invention, for avoiding network transmission conditions instability to cause the second equipment not receive instruction message, first equipment can also be after sending instruction message, generating confirmation message, after number of links confirms instruction and change, the number of links of the first binding group is added in confirmation message.First equipment repeatedly sends confirmation message according to predetermined period to the second equipment, such as first equipment sends a confirmation message every 3ms (millisecond) to the second equipment and continuously transmits 3 times, to guarantee that the second equipment is able to receive that the number of links of the first binding group after change.
After the change added in confirmation message, the number of links of the first binding group is identical with the number of links of the first binding group after the change added in instruction message, and the priority of confirmation message is less than the priority of instruction message.If the second equipment has been received by indicating message, then when receiving confirmation message, confirmation message is not processed by the second equipment, can directly be abandoned.
Further, as to instruction message or the response of confirmation message, the second equipment is after adjusting the second binding group number of links according to instruction message or confirmation message, it is also possible to generates a response message and feeds back to the first equipment.Concrete, the current ink quantity of the second binding group after number of links confirmation instruction and adjustment is added in this response message by the second equipment, and response message is sent to the first equipment.
If the available link quantity in the second binding group (number of links that can use and be being currently used and available but not currently used number of links sum) is less than the number of links of the first binding group after change, in any case then the number of links of the second binding group all can not be adjusted to the quantity equal with the number of links of the first binding group by the second equipment adjustment number of links.Now the second equipment is by all available but not currently used link activations, and after the current ink quantity of the second binding group is adjusted to maximum, after adjusting, the current ink quantity of the second binding group is added to and is sent to the first equipment in response message, in order to the first equipment reduces the current ink quantity in the first binding group according to the current ink quantity of the second binding group after adjusting.
First equipment, after receiving response message, determines that the current ink quantity of the second binding group is the most equal with the current ink quantity of the first binding group after change after adjustment.Determine that result and processing mode have following three kinds of situations:
1) if the current ink quantity of the first binding group is equal with the current ink quantity of the second binding group after adjustment after Bian Hua, then the first equipment and the second equipment carry out proper communication.
2) if the current ink quantity of the first binding group is more than the current ink quantity of the second binding group, the then link that first equipment Removal the first binding group has more than the second binding group after adjusting after Bian Hua.Such as, after change, the current ink quantity of the first binding group is 16, and after adjustment, the current ink quantity of the second binding group is 12, then, after receiving response message, the first equipment removes 4 links from the link of the currently used link of the first binding group.
3) if the current ink quantity of the second binding group is less than the current ink quantity of the first binding group after adjusting, then the first equipment sends instruction message to the second equipment again, it can be specifically to resend the instruction message generated in Fig. 2 that first equipment sends this instruction message again, can also be that in the precedence diagram 2 again of the current ink quantity according to the first binding group, the instruction message regenerated, to step 202, is sent to the second equipment by step 201.
Further, for situation 2), after the first equipment removes 4 links from the link of the currently used link of the first binding group, first equipment also needs to generate a response message, and after removing link, the current ink quantity (12) of the first binding group adds second equipment that is sent in this response message to.The implementation of the first equipment generation response message is identical with the implementation of aforementioned second equipment generation response message, and here is omitted.
In addition, when after the current ink quantity of the second binding group is adjusted to maximum by the second equipment (12) still less than current ink quantity (16) of the first binding group, second equipment is after sending response message to the first equipment, in all right order execution Fig. 2, step 201 is to step 203, the instruction message of the second binding group current ink quantity (12) after adjustment is carried in the first equipment transmission.First equipment receive second equipment send response message after can not according to the adjustment carried in response message after second binding group current ink quantity (12) adjust change after the first binding group current ink quantity (16).After the instruction message that subsequently received second equipment of the first equipment sends, further according to instruction message, the first binding group current ink quantity is reduced to 12, and sends response message to the second equipment.
As can be seen here, the process of Bandwidth adjustment is not limited to disposably adjust, it is also possible to be the process repeatedly consulted between the first equipment and the second equipment, and the number of times of Bandwidth adjustment is not limited by the embodiment of the present invention.
In embodiments of the present invention, the differentiation of the first equipment and the second equipment is only used for ease of describing, and the actually first equipment can also have the correlation function of the second equipment, and the i.e. first equipment can perform the correlation step in Fig. 3；Equally, the second equipment can also have the correlation function of the first equipment, and the i.e. second equipment can perform the correlation step in Fig. 2.
