Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 is the flow chart of the distribution method embodiment one of connection identifier of the present invention, and as shown in Figure 1, present embodiment provides a kind of distribution method of connection identifier, can specifically comprise the steps:
Step 102 is obtained available connection identifier by the identifier pre-allocation pond, described available connection identifier is distributed to newly-built compression connect.
Present embodiment provides a kind of distribution method of connection identifier, bit variable information by storage connection identifier in the sign pond, to indicate the user mode of each connection identifier, the connection identifier that will identify the part free time in the pond according to this bit variable information is pre-assigned in the identifier pre-allocation pond, when new data flow arrives, obtain available connection identifier by the identifier pre-allocation pond, think that newly-built compression connects the available connection identifier of distribution, solved the wasting of resources that the full method of salary distribution is brought in the prior art, realized connecting effective management of contextual connection identifier, saved the memory space of system, improve the treatment effeciency of system, also reduced the transmission delay of data simultaneously.
Fig. 2 is the flow chart of the distribution method embodiment two of connection identifier of the present invention, and as shown in Figure 2, present embodiment provides a kind of distribution method of connection identifier, can specifically comprise the steps:
In the present embodiment, the bit variable information of utilizing the sign pond to store each connection identifier, rather than connection identifier itself.Bit variable information herein is used to indicate the user mode of connection identifier, promptly this connection identifier is in idle condition or user mode, bit variable information in the present embodiment can be " 0 " or " 1 ", when the bit variable information of certain connection identifier correspondence in the sign pond is " 1 ", represent that this connection identifier is in idle condition, it is not used, and can distribute; When the bit variable information of certain connection identifier correspondence in the sign pond is " 0 ", represent that this connection identifier is in user mode, it has been assigned with use, can not be assigned with again, and when connection identifier was assigned in the identifier pre-allocation pond, the bit variable information of this connection identifier was " 0 ".And in the prior art when the configuration of compressing connection, when the maximum number of connections of system configuration is 65535, can employed connection identifier number be 65535 when the system assignment, for IP/ User Datagram Protoco (UDP) (User Datagram Protocol; Hereinafter to be referred as: context UDP) connects, when initialization, need distribute a static storage for each connects context, then can take the memory space of 35535*28*8=14Mbit, wherein 28 is the byte length of the header of IP message and UDP message; For IP/ transmission control protocol (Transmission Control Protocol; Hereinafter to be referred as: TCP), then need to take the memory space of 65535*40*8=20Mbit, wherein 40 is the byte length of the header of IP message and TCP message.Utilize the method in the present embodiment then only to need 65535 bit variables of definition just can store all connection identifier information, and need when initialization, not distribute 65535 chain type memory spaces that connect contexts and sign, this shows, can save the memory space of system greatly, reduce the waste of resource.
This step is obtained the connection identifier of part free time according to the bit variable information of the connection identifier of storing in the pond in sign, and the connection identifier of free time of obtaining is pre-assigned in the identifier pre-allocation pond.The maximum number of connections that supposing the system is determined is 4, can be 1,2,3,4 for the connection identifier of system assignment then, and the initial condition of connection identifier is an idle condition, and then identifying the initial value of the bit variable of the connection identifier of storing in the pond this moment is 1111.Suppose to obtain the pond connection identifier 1 and 2 of two free time, the connection identifier of this two free time be pre-assigned in the identifier pre-allocation pond that the value that identify the bit variable of the connection identifier of storing in the pond this moment is 0011 from sign.The pre-allocation process of connection identifier joins the value of this connection identifier the process in identifier pre-allocation pond simultaneously for the position number value that will identify connection identifier position in the pond is converted into the value of connection identifier in this step.Connection identifier in the identifier pre-allocation pond adopts the chain type management, promptly come the connection identifier of preallocated free time is wherein managed by the connection identifier chain, be that newly-built compression connects when distributing connection identifier, first connection identifier in the connection identifier chain is distributed to current newly-built compression to be connected, when new connection identifier joins in the identifier pre-allocation pond, new connection identifier is added to the afterbody of connection identifier chain.
When having new data flow to arrive, need connect newly-built compression and distribute connection identifier, then directly from the identifier pre-allocation pond, obtain connection identifier to be allocated, rather than from the sign pond, obtain.Because the quantity of the connection identifier in the identifier pre-allocation pond is significantly less than the quantity of the connection identifier in the sign pond, and the connection identifier in the identifier pre-allocation pond is idle connection identifier, can directly be assigned to newly-built compression connects, overcome like this in the prior art when each newly-built compression connects, need the whole sign of traversal pond, thereby can improve the treatment effeciency of system.And, therefore can not cause a large amount of resource occupation owing to only store a spot of connection identifier in the identifier pre-allocation pond.When from the identifier pre-allocation pond, obtaining connection identifier, whether the connection identifier that detects the free time in the identifier pre-allocation pond earlier is empty, if there is not idle connection identifier resource in the identifier pre-allocation pond, then execution in step 203, connection identifier is reclaimed with preassignment operate; If idle connection identifier is arranged in the identifier pre-allocation pond, then execution in step 209, directly are that newly-built compression connects the distribution connection identifier.
When carrying out the recovery of connection identifier, what judge that the compression set up connects has been all to exceed the sign term of validity with connection identifier, concrete according to last service time of connection identifier with identify the term of validity and judge.When certain when exceeding last service time of connection identifier the sign term of validity, show that this has used connection identifier out of date, then execution in step 204, and this link identification is reclaimed; When all not exceeding the sign term of validity with connection identifier, then execution in step 205, continue preassignment connection identifier from the sign pond.
Whether step 204, the quantity of judging in the described identifier pre-allocation pond idle connection identifier greater than the storage cap in described identifier pre-allocation pond, if, execution in step 206, otherwise execution in step 207.
When connection identifier is reclaimed, if certain exceeds the sign term of validity with connection identifier, then this connection identifier is reclaimed, the connection identifier after the recovery at first adds in the identifier pre-allocation pond.Therefore, when this step was added in the identifier pre-allocation pond at the connection identifier that will reclaim, whether the quantity of judging earlier the connection identifier of free time in the current identifier pre-allocation pond was greater than the storage cap in identifier pre-allocation pond; When expire in current identifier pre-allocation pond, then carry out subsequent step 206, this connection identifier is recovered in the sign pond; When current identifier pre-allocation pond less than, then execution in step 207, directly this directly are recovered in the identifier pre-allocation pond with connection identifier.
When all not exceeding the sign term of validity with connection identifier, show and do not have callable connection identifier at present, then continue preassignment connection identifier from the sign pond, similar with step 201, bit variable information according to the connection identifier of storing in the sign pond is obtained idle connection identifier, the connection identifier of free time of getting access to is pre-assigned in the identifier pre-allocation pond, is buffered in the afterbody of connection identifier chain in the identifier pre-allocation pond.
When expire in current identifier pre-allocation pond, that then will reclaim is converted to corresponding bit variable with connection identifier, because this connection identifier is in idle condition at present, then this is made as " 1 " with connection identifier corresponding bit variable information in the sign pond, the bit variable that identifies the connection identifier of storing in the pond is upgraded.
When current identifier pre-allocation pond less than, that then directly will reclaim is cached in the identifier pre-allocation pond with connection identifier, is added on the afterbody of connection identifier chain in the identifier pre-allocation pond equally.
Finish reclaimer operation with connection identifier when what exceed the sign term of validity, promptly after the recovery of finishing connection identifier, whether the quantity of judging connection identifier idle in the current identifier pre-allocation pond is less than the storage cap in identifier pre-allocation pond.If after reclaiming, current identifier pre-allocation pond is not filled up yet, then return execution in step 205, from the sign pond, obtain idle connection identifier, from described sign pond, obtain idle connection identifier according to the bit variable information in the sign pond, add the connection identifier of free time of obtaining the afterbody of the connection identifier chain in described identifier pre-allocation pond to, the quantity of idle connection identifier equals described storage cap in described identifier pre-allocation pond.
Be that newly-built compression connects when distributing connection identifier, the connection identifier that detects the free time in the identifier pre-allocation pond is not for empty, then first connection identifier that can directly obtain the connection identifier chain from the identifier pre-allocation pond is distributed to newly-built compression with available connection identifier and is connected as available connection identifier.
After the distribution of finishing connection identifier, upgrade the quantity of connection identifier idle in the identifier pre-allocation pond, whether the quantity of connection identifier of judging the current free time then is less than default identification number, when the quantity of current connection identifier during less than default identification number, then return execution in step 203, connection identifier is reclaimed with preassignment operate.
Present embodiment provides a kind of distribution method of connection identifier, bit variable information by storage connection identifier in the sign pond, to indicate the user mode of each connection identifier, the connection identifier that will identify the part free time in the pond according to this bit variable information is pre-assigned in the identifier pre-allocation pond, when new data flow arrives, obtain available connection identifier by the identifier pre-allocation pond, think that newly-built compression connects the available connection identifier of distribution, solved the wasting of resources that the full method of salary distribution is brought in the prior art, realized connecting effective management of contextual connection identifier, saved the memory space of system, improve the treatment effeciency of system, also reduced the transmission delay of data simultaneously.
