Above-mentioned technical proposal in order to better understand the present invention is come with reference to 64 bit processors to above-mentioned technical proposal
It is described in detail.
In the present embodiment, it is IPv4 (Internet to the factor that message is concerned about when being matched to message
Protocol Version 4, i.e. Internet Protocol Version 4) message five-tuple information, i.e. source IP address, purpose IP address, source
Port, destination interface, transport layer protocol number are based on this, define the data structure of a five-tuple in the present embodiment：
Wherein, as can be seen that IP address is 32 bits from above-mentioned data structure, port is 16 bits, transport layer protocol
For 8 bits, 104 bit in total, and due to the bit wide that processor in this example is 64 bits, believe in basic five-tuple
The filling that 3 bytes (24 bit) is also added on breath, to make the data length of the five-tuple be 128 bits, wherein at five yuan
Further include one 64 arrays in group data structure, so as to which the five-tuple information of 128 bits is divided into two parts first 64
It is respectively stored in u64ptr [0] and u64ptr [1] with latter 64, five-tuple data basic in this way are just and two 64 fixed for data
Justice is association, common storage space；
Specifically, in order to realize the rule match processing to five-tuple, it is upper to realize two data types in this example
State pkt the and rule objects of union tuple5, wherein for storing message five-tuple information in pkt, be used to store in rule
Regular five-tuple information, and 3 bytes filled are 0；
Two 64 digits of five-tuple thus can be converted to by whether the information of interpretation five-tuple matches with rule
Whether according to identical as 64 data of rule, specific message matching flow is as shown in Figure 2：
Rule (the rule of i.e. to be matched five-tuple of the system in the five-tuple information that message is determined and the corresponding five-tuple
After then), so that it may five-tuple information and Rule Information are respectively classified into two groups, first 64 one group, latter 64 one group, five-tuple (is reported
Text) forward and backward 64 data be respectively pkt.u64ptr [0] and pkt.u64ptr [1], and forward and backward 64 data of rule are divided
Not Wei rule.u64ptr [0] and rule.u64ptr [1], to realize the segmentation to five-tuple and rule, to message and
When rule is segmented respectively, message and rule can be respectively segmented according to the bit wide (being here 64) of processor, from
And make generation message segment and regular section data length it is identical as the bit wide of processor, wherein multiple message segments of generation and
Regular section is one-to-one, i.e. pkt.u64ptr [0] is corresponding with the data that rule.u64ptr [0] is stored, pkt.u64ptr
[1] corresponding with the data of rule.u64ptr [1] storages；
In addition, in this example, also defining two 64 intermediate variables s0 and s1 and being used to preserve interim findings, from Fig. 2
As can be seen that system can to one-to-one pkt.u64ptr [0] and rule.u64ptr [0] and correspondingly
Pkt.u64ptr [1] and rule.u64ptr [1] carry out XOR operation (the first logical operation) respectively, by pkt.u64ptr [0] and
The exclusive or result of rule.u64ptr [0] is stored in temporary variable s0, and then system can carry out s0 logical inversion, and will knot
Fruit is stored in s0, and s0 indicates whether preceding 64 five-tuple information and Rule Information are identical at this time；Likewise, system can incite somebody to action
The exclusive or result of pkt.u64ptr [1] and rule.u64ptr [1] is stored in temporary variable s1, and then system can carry out s1
Logical inversion, and result is stored in s1；Finally, s0 and s1 is carried out logic and operation by system, i.e. the second logical operation obtains
It is stored in matching result in the hit variables for indicating whether this rule of hit (matching), wherein hit is that 0 expression is not hit by this rule
Then, non-zero, it indicates to hit this rule, then in the case where it is 0 to determine matching result, it is determined that the five-tuple information of the message
It is mismatched with corresponding five-tuple rule；And in the case where it is non-zero to determine matching result, then it can determine message five-tuple information
Match with corresponding five-tuple rule.
Can be seen that the message matching method of the present invention from above-mentioned flow can be turned by will determine that whether five-tuple is identical
It is changed to and judges whether two 64 data are identical, and when judging whether two 64 data are identical, by by two data
Exclusive or is carried out, then logical inversion, can thus replace judging sentence, eliminate multiple judgements in the matching process of message
Branch ensures that matching flow will not be branched and interrupts to just complete the rule match of message on an assembly line.
And in another embodiment, if user wants to be part in five-tuple information to the matched information of message
Information, i.e. user are only concerned the partial information in five-tuple information, that is to say, that and the five-tuple information is flexible five-tuple, that
At this point, after simple process can be carried out to five-tuple information and corresponding rule, then carry out the rule of complete five-tuple shown in Fig. 2
Then match flow.
Pre-processing process for flexible five-tuple is as shown in figure 3, first, the rule match process with complete five-tuple
Identical to be, there is still a need for the five-tuple information that message is stored in pkt first, and the rule letter of flexible five-tuple is stored in rule
Breath, then all bits of unconcerned element are arranged to 0 in the five-tuple rule, wherein in flexible five-tuple
The various different situations whether five elements are concerned about, 5 powers (32) kind for sharing 2 combines, i.e., corresponding to flexible five-tuple information
Rule have 32 kinds of rule types.It is pre-configured with 32 regular masks according to rule type.The data type of regular mask is
union tuple5；And for the element of care, then all bits of corresponding element are disposed as 1 in regular mask；
And when the five-tuple information to reception matches, if only needing to match the part in five-tuple,
It just can determine that user is concerned about (i.e. target information) to which of five-tuple information factor, then determined according to the target information
Corresponding rule type, wherein the rule of above-mentioned 32 type is the rule of preconfigured corresponding different target information, then
The regular mask of the corresponding target information can be selected in preconfigured 32 kinds regular mask mask according to the rule type；
Then respectively with two 64 data of the regular mask of selection to two 64 data in five-tuple information carry out step-by-step with
Operation, i.e., pkt.u64ptr [0] ＆=mask.u64ptr [0], pkt.u64ptr [1] ＆=mask.u64ptr shown in Fig. 3
[1], pass through this step-by-step and operation, so that it may make the numerical value of unconcerned element in five-tuple information all 0, i.e., with it is corresponding
The numerical value of corresponding unconcerned element is identical in rule；Finally, then to the pkt five-tuples information and correspondence Jing Guo above-mentioned processing
Rule rules carry out the rule match flow of complete five-tuple as shown in Figure 2, specific steps are same as above one to Fig. 2 institutes
