Fig. 1 is referred to, Fig. 1 is the operation principle schematic diagram that routing keeps mechanism.As shown in Figure 1, load-balancing device 10
Outgoing interface 30 and outgoing interface 40 (are only shown, the actual bandwidth resource of each outgoing interface circuit is not by a plurality of outgoing interface circuit in figure
It E-Packets to ISP (Internet Service Provider, Internet Service Provider) together).It is assumed that user initiates for the first time
Network service data forwarded from load-balancing device 10 by outgoing interface 30 to ISP, and user subsequently initiates identical network
Business datum (i.e. network purpose is identical) is dispatched to outgoing interface 40 by load-balancing device 10, due to being forwarded by different outgoing interfaces
The source IP address of network data also differ, the data which subsequently forwards are it is possible that can be by server-side (i.e. opposite end
ISP) refusal, then lead to service disconnection.Therefore it needs to keep mechanism by routing so that follow-up identical network service number
According to being forwarded by outgoing interface 30 to ISP, to ensure that the network service is unaffected.
In the related art, when outgoing interface 30 overloads, by the new business data dispatch on outgoing interface 30 to other not
The outgoing interface of overload, and the data (belonging to the business of establishment) forwarded by outgoing interface 30 are carried out yet by outgoing interface 30
Forwarding, so as to avoid mechanism being kept to clash with routing.However, due to the diversity of network service, business has been created still
It is likely to be such that outgoing interface 30 is chronically at overload condition, so as to cause the situation of packet loss or delay, influences institute on outgoing interface 30
There is the normal forwarding of the business of establishment.
Therefore, the application gives by way of to scheduling outgoing interface and improves, above-mentioned present in the relevant technologies to solve
Technical problem.It is described in detail with reference to embodiment.
Fig. 2 is referred to, Fig. 2 is a kind of flow chart of message forwarding method shown in one exemplary embodiment of the application, should
Method is applied to load-balancing device, may comprise steps of：
Step 202, when the outgoing interface of the forwarding object message of selection overloads, go out to connect if the object message belongs to described
The new business or the affiliated business of the object message of mouth occupy industry for the high bandwidth in the business of establishment of the outgoing interface
Business then chooses other outgoing interfaces not overloaded and forwards the object message.
In the present embodiment, when the outgoing interface of the forwarding object message of selection overloads, if object message belongs to newly-built industry
Business (does not keep mechanism to conflict) with routing, then can choose other outgoing interfaces not overloaded and forward the object message, so as to
The flow of the outgoing interface of overload is avoided to continue to increase, alleviates the overload condition of the outgoing interface.If the affiliated business of object message is is somebody's turn to do
High bandwidth in the business of establishment of outgoing interface (the above-mentioned outgoing interface in overload condition) occupies business, and (high bandwidth occupies
Business is to meet the business of predefined bandwidth condition), then it can equally choose other outgoing interface forwarding object messages not overloaded.
Belong to the opposite larger business of occupied bandwidth in all business of the interface since high bandwidth occupies business, by by high bandwidth
The message of occupancy business is forwarded by the interface that other do not overload, can be chronically at overload condition to avoid the outgoing interface of overload；
Meanwhile in addition the message (being influenced on the overload of interface smaller) of the smaller business of opposite occupied bandwidth can normally turn in the interface
Hair, it is unaffected.
Wherein, load-balancing device record is with having the source IP address for having created business and the destination IP of each outgoing interface
Location；It can determine that the object message is directed to the affiliated type of service of the outgoing interface in the following manner：If the target report
Text source IP address and purpose IP address it is identical with the source IP address for having created business and purpose IP address of the outgoing interface or
Person is on the contrary, then the object message belongs to the establishment business of the outgoing interface, and otherwise, the object message belongs to described and goes out to connect
The new business of mouth.Meanwhile the business configuration of establishment of the load-balancing device record has aging duration；It has been created when any
Build in the ageing time of business do not forward belong to it is described it is any created business message when, any business that created is deleted
It removes.
In the present embodiment, it can determine whether the affiliated business of the object message is the outgoing interface in the following manner
The business of establishment in high bandwidth occupy business：First (the overload flow is described to the overload flow of the determining outgoing interface
Beyond the sum of the part of uplink threshold value and the part for exceeding downlink threshold value in downlink traffic in outgoing interface uplink traffic), then press
The business of establishment of the outgoing interface is ranked up according to the sequence of total flow from big to small, each total flow for having created business
It is the sum of respective transmission data and reception data；Choose the establishment industry of the outgoing interface successively further according to the sequence after sequence
Business, until the sum of selected total flow of business is not less than the overload flow.Meet above-mentioned condition (i.e. it is above-mentioned refer to it is pre-
Define bandwidth condition) the business of establishment can be determined as high bandwidth occupy business.Based on the above-mentioned choosing to having created business
It takes, then business can be occupied using the selected business of establishment as the high bandwidth.It specifically, can be in the outgoing interface
When the duration of sustained overload is more than predetermined threshold value, the sorting operation is performed.By setting predetermined threshold value sequence is performed to limit
The frequency of operation, can effectivelying prevent the frequency for performing above-mentioned sorting operation, excessively high (outgoing interface may only in a short time sometimes
In overload condition, and subsequently can soon quick-recovery to normal condition), cause to influence the performance of equipment.It should be noted that work as institute
When the uplink traffic for stating outgoing interface is more than that uplink threshold value or downlink traffic are more than downlink threshold value, the outgoing interface can be judged as surpassing
It carries.
Step 204, otherwise, the object message is forwarded by the outgoing interface.
By above technical scheme as it can be seen that when outgoing interface is in overload condition, the application belongs to the outgoing interface by determining
New business and high bandwidth occupy business (such service traffics occupies the relatively large bandwidth of the outgoing interface, if continuing to lead to
The data that outgoing interface forwarding high bandwidth occupies business are crossed, then will aggravate the situation of overload), and that chooses that other do not overload goes out to connect
Mouth forwarding new business and high bandwidth occupy the message of business, can effectively alleviate the situation of outgoing interface link congestion so that go out
Interface can be chronically at the state normally forwarded.Meanwhile it ensure that part has created business (i.e. occupied bandwidth in the outgoing interface
Smaller business) it is unaffected, it can be normally carried out forwarding.
In order to make it easy to understand, the technical solution of the application is described in detail below in conjunction with the accompanying drawings.
Fig. 3 is referred to, Fig. 3 is the flow chart of another message forwarding method shown in one exemplary embodiment of the application,
This method is applied to load-balancing device, may comprise steps of：
Step 302, object message is received.
Step 304, outgoing interface is chosen.
In the present embodiment, load-balancing device obtains forwarding object message by query routing sub-process and (receives
The message that forwards of needs) outgoing interface.
Step 306, whether the outgoing interface for judging to choose overloads, if overload, is transferred to step 308, is otherwise transferred to step
314。
In the present embodiment, the uplink traffic of each outgoing interface of load-balancing device real-time update (outgoing interface transmission data
Total amount) and downlink traffic (outgoing interface receives the total amount of data), and (be directed to and each go out with corresponding uplink threshold value, downlink threshold value
Interface is equipped with uplink threshold value and downlink threshold value) it is compared；When a certain outgoing interface uplink traffic be more than uplink threshold value or under
When row flow is more than downlink threshold value, at the time of judging the outgoing interface for overload, and record outgoing interface overload at this time, to determine that this goes out
The duration of interface sustained overload.
For example, load-balancing device can safeguard overload dispatch list as shown in Table 1：
Table 1
Step 308, judge whether object message belongs to the new business of selected outgoing interface, if belonging to, be transferred to step
Rapid 312, otherwise it is transferred to step 310.
Step 310, judge the affiliated business of object message whether be outgoing interface the business of establishment in high bandwidth occupy industry
Business occupies business if high bandwidth, is then transferred to step 312, is otherwise transferred to step 314.
In the present embodiment, when the outgoing interface of the forwarding object message of selection overloads, if object message belongs to newly-built industry
Business (does not keep mechanism to conflict) with routing, then can choose other outgoing interfaces not overloaded and forward the object message, so as to
The flow of the outgoing interface of overload is avoided to continue to increase, alleviates the overload condition of the outgoing interface.If the affiliated business of object message is is somebody's turn to do
High bandwidth in the business of establishment of outgoing interface (the above-mentioned outgoing interface in overload condition) occupies business, and (high bandwidth occupies
Business is to meet the business of predefined bandwidth condition), then it can equally choose other outgoing interface forwarding object messages not overloaded.
Belong to the opposite larger business of occupied bandwidth in all business of the interface since high bandwidth occupies business, by by high bandwidth
The message of occupancy business is forwarded by the interface that other do not overload, can be chronically at overload condition to avoid the outgoing interface of overload；
Meanwhile in addition the message (being influenced on the overload of interface smaller) of the smaller business of opposite occupied bandwidth can normally turn in the interface
Hair, it is unaffected.
Specifically, load-balancing device record is with having the source IP address for having created business and the destination IP of each outgoing interface
Location.It can so determine that object message is directed to the affiliated type of service of the outgoing interface in the following manner：If object message
Source IP address and purpose IP address are identical or opposite with the source IP address for having created business and purpose IP address of the outgoing interface
(belonging to same data flow), then object message belong to the establishment business of the outgoing interface, otherwise, object message belongs to this and goes out to connect
The new business of mouth.Meanwhile the business configuration of establishment of load-balancing device record has aging duration；When having created industry any
Do not forwarded in the ageing time of business belong to this it is any created business message when, this of deletion record any has created business.
After determining that object message belongs to establishment business, it can determine whether the affiliated business of object message is that this goes out in the following manner
High bandwidth in the business of establishment of interface occupies business：First (overload flow is outgoing interface to the overload flow of the determining outgoing interface
Beyond the sum of the part of uplink threshold value and the part for exceeding downlink threshold value in downlink traffic in uplink traffic), then according to total stream
The sequence of amount (each total flow for having created business is respective transmission data with receiving the sum of data) from big to small goes out to connect to this
The business of establishment of mouth is ranked up；Choose the establishment business of the outgoing interface, Zhi Daosuo successively further according to the sequence after sequence
The sum of total flow of business of selection is not less than overload flow.Wherein, meet above-mentioned condition and (also predefine bandwidth item
Part) the business of establishment can be determined as high bandwidth occupy business.Based on the above-mentioned selection to having created business, then can be with
Business is occupied using the selected business of establishment as high bandwidth.It should be noted that can outgoing interface sustained overload when
When length is more than predetermined threshold value, sorting operation is performed.The frequency for performing sorting operation, Ke Yiyou are limited by setting predetermined threshold value
Effect prevents the frequency for performing above-mentioned sorting operation, and excessively high (outgoing interface may be only in a short time in overload condition, then sometimes
It is continuous can soon quick-recovery to normal condition), lead to the performance of influence equipment.
For example, load-balancing device can record the practical details to E-Packet of each outgoing interface, and be directed to
Each outgoing interface generation forwarding data details table as shown in Table 2：
Table 2
Wherein, each list item in table 2 can be regarded as having created business.Load-balancing device is passing through a certain outgoing interface
When E-Packeting, the forwarding data details table of the outgoing interface can be traversed, there is identical source IP address with the message when existing
During with the list item of purpose IP address, the data length of the message is added in the transmission data of the list item；When presence and the report
When the source IP address of text, the opposite list item of purpose IP address, the data length of the message is added to the reception data of the list item
In；When there is no there is identical or opposite IP address and purpose IP address with the message, in forwarding data details table
In create a list item to record the details of the message；After cumulative data length or newly-built list item, need to " during update
Between " be updated.For example, load-balancing device is E-Packeted by outgoing interface Gige_1 (it is assumed that table 2 is the forwarding of the outgoing interface
Data details table), if the source IP address of the message is 1.1.1.1, purpose IP address 202.1.1.1, then in list item 1
The data length of the cumulative message in " transmission data " of (list item of serial number 1), and update " renewal time "；If the message
Source IP address is 202.1.1.1, and purpose IP address is 1.1.1.1 (response message for receiving opposite end return), then in list item 1
" receive data " in add up the data length of the message, and update " renewal time ".And it is each equipped with always for each list item
Change duration, when any list item does not update in the aging duration of the list item, delete the list item.
Based on the above-mentioned configuration to overload dispatch list and forwarding data details table, connect being selected by step 304
After mouthful, dispatch list can be overloaded by inquiry to determine whether selected outgoing interface overloads, if not overloading, will directly be received
To object message be forwarded by the outgoing interface；Otherwise, it needs further detailed by inquiring the forwarding data of the outgoing interface
Thin information table determines whether object message belongs to whether new business and its affiliated business are that high bandwidth occupies business.Its
In, it, can if there is the source IP address and purpose IP address identical or opposite with object message in forwarding data details table
To determine that object message belongs to the establishment business of selected outgoing interface, then needs further determine whether to occupy for high bandwidth
Business；Otherwise, it may be determined that object message belongs to new business, then directly trigger again routing sub-process to choose other not
The outgoing interface forwarding object message of overload.For example, the source IP address of object message is 1.1.1.3, purpose IP address is
202.1.1.3, it is that (it is assumed that predetermined threshold value is 3min, i.e., the outgoing interface persistently surpasses Gige_2 by the outgoing interface that step 304 is chosen
The duration of load is more than predetermined threshold value；Meanwhile the affiliated business of object message is included in the business of establishment of the outgoing interface).So, go out
The overload flow of interface Gige_2 is 50MB.Since the duration of outgoing interface Gige_2 sustained overloads is more than predetermined threshold value, triggering pair
The sorting operation of the list item of the forwarding data details table of outgoing interface Gige_2.It is assumed that the sequence according to total flow from big to small
The list item (having created business) of outgoing interface Gige_2 is ranked up, the sum of total flow of preceding 10 list items is obtained and is not less than
50MB；Can so choose preceding 10 list items it is corresponding created business as high bandwidth occupy business, that is, sort after before
" the overload scheduling " of 10 list items is "Yes".If the affiliated business of object message (the establishment business for outgoing interface Gige_2)
When " overload scheduling " is "Yes" (as ranking occupies business positioned at preceding 10 high bandwidth), then routing sub-process is triggered again to select
Take the outgoing interface forwarding object message that other do not overload；Otherwise, object message is forwarded yet by outgoing interface Gige_2.Certainly, originally
Determining for business is occupied for high bandwidth in application, other modes can also be used：For example, default ranking is chosen after sorted
It has created business and has occupied business as high bandwidth；As long as it can determine to occupy band to be opposite in all business of establishment of outgoing interface
Wide larger business, the application are limited not to this.
Step 312, other outgoing interface forwarding object messages not overloaded are chosen again.
Step 314, object message is forwarded by selected outgoing interface.
It should be noted that the specific value of the parameters such as predetermined threshold value, aging duration can be according to actual conditions in the application
Flexibly setting, the application are limited not to this.
By above technical scheme as it can be seen that when outgoing interface is in overload condition, the application belongs to the outgoing interface by determining
New business and high bandwidth occupy business (such service traffics occupies the relatively large bandwidth of the outgoing interface, if continuing to lead to
The data that outgoing interface forwarding high bandwidth occupies business are crossed, then will aggravate the situation of overload), and that chooses that other do not overload goes out to connect
Mouth forwarding new business and high bandwidth occupy the message of business, can effectively alleviate the situation of outgoing interface link congestion so that go out
Interface can be chronically at the state normally forwarded.Meanwhile it ensure that part has created business (i.e. occupied bandwidth in the outgoing interface
Smaller business) it is unaffected, it can be normally carried out forwarding.
