Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these figure.
Fig. 1 is the schematic flow sheet of the time-out time method to set up of a kind of connection that one embodiment of the invention provides;
Fig. 2 is the structural representation of the time-out time setting device of a kind of connection that another embodiment of the present invention provides.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 shows the schematic flow sheet of the time-out time method to set up of a kind of connection provided for one embodiment of the invention, and as shown in Figure 1, the method comprises the steps:
S1: when network equipment foundation newly connects, obtain this network equipment completes foundation number of connection at current point in time.
Wherein, the network equipment carries out connection establishment based on IP five-tuple usually, and the message that IP five-tuple is identical is considered to same stream, then the message that IP five-tuple is identical is through same connection.In this step, upon setup of a new connection, acquisition equipment completes the number of connection of foundation at current point in time, as acquisition equipment to complete the number of connection of foundation at 6.
S2: the number of connection and the predetermined threshold value that described current point in time are completed foundation compare.
Wherein, predetermined threshold value can be arranged according to the actual capacity of the network equipment.
Preferably, predetermined threshold value w can obtain according to formula (1):
w＝m/(t*q)(1)
Wherein, m is the supported maximum number of connections of this network equipment, and t is that every bar connects the time-out time preset, and q connects required time for deleting.
For example, a supported maximum number of connections m of the network equipment is 1,000,000, and it is 30*60 second that every bar connects the time-out time t preset, and deletion connection required time q is 1s, and in extreme circumstances, suppose that this connection of 1,000,000 at one time and roll off the production line in 1s.Then now can calculate w according to formula (1), and using w as predetermined threshold value.
S3: if described number of connection is greater than predetermined threshold value, then extend the time-out time preset, and using the time-out time of the time-out time after prolongation as this connection.
For example, the time-out time preset is 30*60 second.When then setting up each new connection, number of connection current point in time being completed foundation compares with predetermined threshold value, if this number of connection is greater than predetermined threshold value, then extends the time-out time preset.
It should be noted that, if described number of connection is less than or equal to predetermined threshold value, then direct using the time-out time of default time-out time as this new connection.
Further, after have passed through the time-out time of this connection above-mentioned, this connection is checked, if there is no message in preset time period through this connection, then delete this connection.
As can be seen here, the time-out time method to set up of a kind of connection that the present embodiment provides, can efficiently avoid peak period and connect frequent problem of deleting, improve the efficiency of data retransmission, improve the utilance of the network equipment.
In the present embodiment, step S3 specifically comprises:
If the number of connection that current point in time completes foundation is greater than the predetermined threshold value of N times and is less than or equal to N+1 predetermined threshold value doubly, then the deletion time-out time of this connection being set to time-out time and N times preset is connected required time sum;
Wherein, described N be more than or equal to 1 integer.
For example, if predetermined threshold value is 500, the time-out time preset is 30*60s, and deleting connection required time is 1s.If the number of connection that then current point in time completes foundation is greater than 500 and is less than or equal to 1000, then the time-out time of this connection is set to (30*60+1) s; And the number of connection that current point in time completes foundation is greater than 1000 and is less than or equal to 1500, then the time-out time of this connection is set to (30*60+1*2) s, like this like.Then according to the time of connection establishment, during time delay 30 minutes, the most multipair front 500 connections are deleted, during time delay 30 minutes 1s, the 500th article to 1000 articles connections are deleted, during time delay 30 minutes 2s, the 1000th article to the 1500th article connection is deleted, the like, then each unit erasing time deletes at most 500 connections.
As can be seen here, pass through said method, can ensure to connect within the scope of the time-out time of calculating a time-out, by average for all connections time-out to each time point, namely when the equipment limit is fully loaded, each timing node has the connection of par deleted, so, by whole deletion action on average on whole timing node, carrying out par devices to deleting the performance loss connecting and bring, avoiding concentrating at a time point integral device degradation problem deleted and connect and cause.
After step S1, the method also comprises:
Current point in time in step S1 is saved as this establishment of connection time point.
Then further, one of the present embodiment preferred embodiment in, described method also comprises the steps:
A01: when this network equipment CPU is idle, detect the connection having extended time-out time in the described network equipment;
A02: obtain current point in time and the described difference having extended the establishment of connection time point of time-out time, and this difference and described default time-out time are compared;
A03: if this difference is greater than described default time-out time, then delete described connection.
For example, when the CPU of the network equipment is idle, can scan connection data storehouse, a time-out time had been carried out to the connection extended, such as an establishment of connection time point is 6 points, and the time-out time point preset during owing to connecting should be 6: 30, by time delay of the present invention by 6: 35, can scan connection when so cpu is idle, find that current time has exceeded 6: 30 in 6: 31, so deleting with regard to directly carrying out connection.
So, the time effectively utilizing the network equipment CPU free time deletes the connection that time-out time had carried out extending, effectively improves the utilance of the network equipment.
As shown in Figure 2, the structural representation of the time-out time setting device of a kind of connection provided for another embodiment of the present invention, this device comprises: acquiring unit 201, comparing unit 202 and time-out time setting unit 203.Wherein:
