In order to realize according to the continuous use memory cell of sequence number order from small to large, in this step, the sequence number of confirming this designated memory cell adds 1 value that obtains for the quantity of the total interface index set up; For example; As shown in Figure 7, currently set up 2 interface indexs, and the type of 2 interface indexs is EtherType; The sequence number of this designated memory cell of the interface pointer of then definite this specified interface of preservation is the value that 2+1 obtains, and is 3.It is in 3 the memory cell that the interface pointer that is about to this specified interface is kept at sequence number.
Step S606, when this quantity non-0 the time; Expression has established the interface index of this interface type; Then confirm the start sequence number that this interface type is corresponding in this step; This start sequence number is in this index stores space, preserves the sequence number of memory cell of interface pointer of first interface of this interface type.
In the present embodiment 1, each upgrade this start sequence number after, preserve this start sequence number, and directly obtain in use and get final product.
Step S607, be this specified interface distribution interface index; In the present embodiment 1; Interface index comprises type number and serial number; Type number in the interface index that then distributes for this specified interface be the corresponding type number of this interface type, and the serial number in the interface index of distribution is that this definite among above-mentioned steps S602 quantity adds 1 value that obtains.
Concrete, interface index can use 4 bytes to amount to 32 to represent that wherein most-significant byte is used to represent type number; Low 24 are used for the order of representation numbering; For example, in the present embodiment 1, the type number of distributing for EtherType is 0x01 (wherein 0x representes the hexadecimal counting); The type number of distributing for the ATM type is 0x02; And confirm that the interface type of specified interface is the ATM type among the hypothesis above-mentioned steps S601, and this definite quantity is 2 among the above-mentioned steps S602, then is that the interface index of this specified interface distribution of ATM type is 0x020003 in this step.
This step S607 and above-mentioned steps S606 do not have strict sequencing.
Step S608, after being this specified interface distribution interface index; In the index stores space of distributing for this designated equipment; Confirm to be used to preserve the designated memory cell of the interface pointer of this specified interface, and the interface pointer of this specified interface is kept in this designated memory cell.
Preferable; Can also the interface index that distribute for this specified interface be kept in this designated memory cell; Be used for follow-up the time according to the corresponding interface message of specified interface search index; Whether with the specified interface index of desire inquiry consistent, so that confirm the interface pointer of preserving in this memory cell more accurately, be the interface pointer of the interface of this specified interface index correspondence if can compare the interface pointer of preserving in the memory cell in advance; Obviously, in the time the time need not carrying out this affirmation in inquiry and handle, saving interface index not in the memory cell.
In order to realize, and make that the interface pointer of interface of same-interface type is to remain in the continuous memory cell of sequence number, in this step according to the continuous use memory cell of sequence number order from small to large; The sequence number of confirming this designated memory cell adds that for this start sequence number the serial number in the interface index of distribution deducts 1 value that obtains again; For example, as shown in Figure 8, the current interface index of having set up 2 EtherTypes; Set up the interface index of 2 ATM types; And the corresponding start sequence number of ATM type is 3, and the sequence number of this designated memory cell of the interface pointer of then definite this specified interface of preservation is the value that 3+3-1 obtains, and is 5.It is in 5 the memory cell that the interface pointer that is about to this specified interface is kept at sequence number.
Through above-mentioned step S601-step S608 shown in Figure 6; In a continuous index stores space of distributing, realized the distribution of dissimilar interface indexs and the preservation of index management information, and; Make in the index stores space; Be according to the sequence number memory cell that uses in order from small to large, thereby when being this designated equipment allocation index memory space, the memory space that only distributes the memory cell with the maximum interface quantity of this designated equipment to be equal to get final product; Compare the scheme that is respectively every kind of interface type allocation index memory space in the prior art, reduced the waste in index stores space.
