It, can be according to each Message processing flowing water of shared buffer queue when determining that the network equipment enters network congestion condition
The significance level of line current bearer determines pause Message processing assembly line and normal from each Message processing assembly line
Message processing assembly line.Based on the associated description hereinbefore to Message processing assembly line in the network equipment it is found that in the present embodiment,
Different Message processing assembly lines carries different business in the network equipment, and the significance level of different business may be endless
It is exactly the same.It, can will be in each Message processing assembly line in some practical applications in order to preferentially guarantee the service quality of important service
The Message processing assembly line that carry the business of lower significance level is determined as suspending Message processing assembly line, higher by carry
The Message processing assembly line of the business of significance level is determined as normal message processing assembly line.For example, when the report in the network equipment
It, can be according to the significance level of each Message processing assembly line bearer service to Message processing flowing water when text processing assembly line is 5
Line is ranked up, and the lower 2 Message processing assembly lines of significance level is determined as to suspend Message processing assembly line, by other 3
Message processing assembly line is determined as normal message processing assembly line.
Assembly line is handled based on the pause Message processing assembly line determined and normal message, when message reaches the network equipment
Communication interface when, the corresponding Message processing assembly line of outgoing packet can be determined, when message is corresponding according to the corresponding business of message
When Message processing assembly line is pause Message processing assembly line, which will be dropped, and work as the corresponding Message processing stream of message
When waterline is normal Message processing assembly line, which can be received normally to buffer queue.Accordingly, in the present embodiment, can lead to
The message that pause receives pause Message processing assembly line institute bearer service is crossed, pause Message processing assembly line is carried to suspend
The processing of business focuses on the available resources of the network equipment in the processing of normal message processing assembly line institute bearer service.
Example in undertaking, when message suspends the message of Message processing assembly line institute bearer service for 2, which will be dropped, this makes
The messages for obtaining no longer newly-increased 2 pauses Message processing assembly line institute bearer service in buffer queue, accordingly, at 2 pause messages
Assembly line is managed to operate pause.
In the present embodiment, available cache resources amount in the buffer queue by detecting the network equipment, it may be determined that network is set
It is standby whether network congestion to occur；When network congestion occurs, can according to the significance level of each Message processing assembly line bearer service,
Pause Message processing assembly line and normal message processing assembly line are determined from each Message processing assembly line；And it can suspend and connect
Receive the message of pause Message processing assembly line current bearer.This allows to selectively be received according to business significance level
The message of partial service advantageously reduces the packet loss of important service into buffer queue, is effectively improved the service of important service
Quality.
In above-mentioned or following embodiments, pause receive pause Message processing assembly line current bearer message it
Afterwards, with the continuous running of each normal message processing assembly line, available cache resources amount is by dynamic change in buffer queue.
Accordingly, it can be continued to test in buffer queue after the message that pause receives pause Message processing assembly line current bearer
Available cache resources amount；When continuing to test available cache resources amount still less than preset lower limit value, according to normal message
The significance level for handling assembly line current bearer is determined to be changed to from pause message from normal message processing assembly line
The Message processing assembly line of assembly line is managed, and suspends the Message processing assembly line for receiving and being changed to suspend Message processing assembly line and works as
The message of preceding bearer service.
If continuing to test available cache resources amount still less than preset lower limit value, illustrate that normal message handles assembly line
The cache resources amount of occupancy is still larger, and the network equipment is still in network congestion condition.In this case, it can normally be reported from each item
The lower Message processing assembly line of significance level that institute's bearer service is chosen in text processing assembly line is changed to pause Message processing
Assembly line.Example hereinbefore is accepted, if at according to 2 pause Message processing assembly lines in the network equipment and 3 normal messages
After the configuration progress business processing for managing assembly line, the network equipment is still in network congestion condition, then can be from 3 normal messages
1 Message processing assembly line of selection is changed to pause Message processing assembly line in reason assembly line will include in the network equipment accordingly
3 pause Message processing assembly lines and 2 normal messages handle assembly line.
The quantity that assembly line is handled by reducing normal message, can further alleviate the network congestion condition of the network equipment.
Certainly, the operation for detecting available cache resources amount in the buffer queue of the network equipment is the behaviour of an intermittent and duration
Make, after the proportional arrangement of pause class and normal class in the adjustment network equipment in each Message processing assembly line, inspection can be passed through
Available cache resources amount in the buffer queue of the network equipment is surveyed to set to determine the effect of adjustment when can not still change network
When standby network congestion condition, the quantity for reducing normal message processing assembly line can be continued, until the network congestion of the network equipment
State is changed.In practical applications, the Message processing assembly line of lesser amt ratio usually need to be only determined as to pause report
Text processing assembly line can effectively change the network congestion condition of the network equipment, therefore, it is ensured that the clothes of most of important service
Business quality.
As mentioned previously, the quantity that assembly line is handled by reducing normal message in the network equipment, can improve network and set
Standby network congestion state, this is mainly due to receive in buffer queue with the reduction of normal message processing assembly line quantity
The message amount arrived will also be reduced, and in buffer queue clear text constantly handled, it is available slow in buffer queue
Depositing stock number will increase.Therefore, in the present embodiment, when detect available cache resources amount be greater than or equal to preset upper limit
When value, according to the significance level of pause Message processing assembly line current bearer, determined from pause Message processing assembly line
It reverts to the Message processing assembly line of normal message processing assembly line again out, and is reverting to normal message processing flowing water again
The message of the Message processing assembly line current bearer of line normally receives when reaching into buffer queue.Wherein, preset upper limit
Value can be greater than or equal to preset lower limit value mentioned above.
When detecting that available cache resources amount is greater than or equal to preset upper limit value, illustrate that the network equipment comes into net
The unobstructed state of network, the network equipment can carry more business at this time.Accordingly, one can be chosen from pause Message processing assembly line
Or a plurality of Message processing assembly line reverts to normal message processing assembly line, and normal message in the network equipment is also handled flowing water
The ratio of line is turned up, to handle more business.Certainly, be turned up the network equipment in normal message processing assembly line ratio
Afterwards, available cache resources amount in the buffer queue of the network equipment can be continued to test, when detect available cache resources amount according to
When being so greater than or equal to preset upper limit value, the ratio that normal message processing assembly line is turned up can be continued, and it is available when detecting
When cache resources amount is less than preset lower limit value, then the ratio for reducing normal message processing assembly line is needed.
Accordingly, in the present embodiment, can according to the dynamic change of cache resources amount available in the buffer queue of the network equipment,
The specific gravity of normal message processing assembly line in the network equipment is adaptively adjusted, thus, the network equipment can be made to operate in comparison steady
Fixed network state, and the service quality of business more as far as possible can be improved.

The priority of each Message processing assembly line, wherein the type of business can indicate the significance level of business；At each message
The priority of assembly line is managed, at least one Message processing assembly line for selecting priority minimum is as pause Message processing flowing water
Line.
In the present embodiment, when determining pause Message processing assembly line, industry can be carried according to each Message processing assembly line
The type of business defines the priority of each Message processing assembly line.As mentioned previously, the bearer service of Message processing assembly line
It is dynamic change, therefore, the type of each Message processing assembly line current bearer can be monitored in real time, and in each message
When the type of processing assembly line current bearer changes, the priority of each Message processing assembly line is dynamically adjusted.This
Sample, in the network equipment priority of each Message processing assembly line can with the variation of bearer service dynamic change.Moreover, with
The processing status of the dynamic change of the priority of Message processing assembly line, Message processing assembly line may also dynamic change.For example,
When the priority of Message processing assembly line is lower, it is confirmed as suspending class Message processing assembly line, and works as Message processing stream
The business that waterline is carried changes when the priority of the Message processing assembly line being caused to increase, which will
It is adjusted to normal message processing assembly line.This can guarantee matching to the processing status of Message processing assembly line each in the network equipment
The compatible degree between each Message processing assembly line bearer service is set, careless omission processing important service is avoided.
Wherein, the type of business include but is not limited to Enterprise Resources Plan (Enterprise Resource Planning,
ERP), database, office automation (Office Automation, OA), web video, game on line etc..The type of business can
The significance level of business is symbolized, for example, the significance level of ERP is generally higher than the significance level of game on line.In some realities
In the application of border, the type of business and the corresponding relationship of priority can be pre-established, it accordingly, can be according to each Message processing assembly line
The type of institute's bearer service, determines the priority of each Message processing assembly line.For example, if the range of priority is determined as 0
~2, the type of each business can be ranked up according to significance level, and be associated with to suitable numerical priority value.
It accordingly, can be according to preferential when each Message processing assembly line carries out the configuration of processing status in the network equipment
Grade is ranked up each Message processing assembly line in the network equipment, by at least one Message processing assembly line that priority is minimum
As pause Message processing assembly line, and assembly line is handled using other Message processing assembly lines as normal message.In this way, can incite somebody to action
The relatively low business pause of significance level, and preferentially guarantee that important service is normally processed.
In conjunction with the detection network equipment buffer queue in available cache resources amount operation, in the present embodiment, can will adjust
The dynamics of normal message processing assembly line and pause Message processing assembly line ratio is set as at a message in the whole network equipment
Manage assembly line.When the network equipment is in network congestion condition, it can be handled in assembly line from normal message choose priority every time
A minimum Message processing assembly line is changed to pause Message processing assembly line, and continues to test the buffer queue of the network equipment
In available cache resources amount, if the network equipment still in network congestion condition, continues from remaining from normal message processing
A minimum Message processing assembly line of priority is chosen in assembly line and is changed to pause Message processing assembly line, until network is set
It is standby to be detached from network congestion condition.And when the network equipment enters the unobstructed state of network, it every time can be from pause Message processing assembly line
A middle Message processing assembly line for choosing highest priority reverts to normal message processing assembly line, and continues to test network and set
Available cache resources amount in standby buffer queue, if the network equipment still in the unobstructed state of network, continue from it is remaining from
The Message processing assembly line that highest priority is chosen in pause Message processing assembly line reverts to normal message processing flowing water
Line, until the discovery network equipment leaves the unobstructed state of network.
It in practical applications, can be by the way that the preset upper limit value referred in previous embodiment be set greater than pre-determined lower limit
Value defines a network steady state between network congestion condition and the unobstructed state of network for the network equipment, and by network
Steady state is as adjustment target, by adjusting normal message processing assembly line in the network equipment and pause Message processing assembly line
