For example, which includes protocol header example H1, which is that the protocol header is real What example H1 was generated analyzes the instruction to analyze the instruction B1.This, which analyzes the instruction B1 and is used to indicate the network equipment, receives including protocol header When the message of example H1, by protocol header example H1 storage to first communal space.

Specifically, analyzing the instruction for each protocol header example may include duplicate instructions, the operation object of the duplicate instructions The location information of the memory space of content and the protocol header example including the protocol header example, that is to say, that multiple by this The content of the protocol header example can be copied to the memory space of the protocol header example by system instruction；

Optionally, it can also include table-look-up instruction that this, which is analyzed the instruction, and the operation object of the table-look-up instruction includes needing to look into The location parameter of the mark and lookup key of the protocol header example of table in messages, for example, if the protocol header example be with Too agreement, which can be ethType field, then the operation object of the table-look-up instruction may include ether association The location parameter of the mark and ethType field of view in messages.Pass through available agreement of tabling look-up according to above- mentioned information The information of next layer protocol head example of head example, may include next layer protocol head in the information of next layer protocol head example The corresponding storage address analyzed the instruction of example.

Optionally, it can also include jump instruction that this, which is analyzed the instruction, for jumping to after having stored the protocol header example The corresponding storage address analyzed the instruction of next layer protocol head example.

S340, the network equipment by each of the first protocol header example collection the first protocol header example from this first It is deleted in network protocol figure, and the directed edge connecting in the first network protocol figure with each first protocol header example is deleted It removes, obtains the second network protocol figure.

It is the first protocol header example collection first communal space of distribution in the first network protocol figure in the network equipment, And after generating corresponding analyze the instruction, which can be by the first protocol header of each of the first protocol header example collection Example is deleted from the first network protocol figure, and will be in the first network protocol figure and in the first protocol header example collection The oriented edge contract of each first protocol header example connection, to obtain the second network protocol figure.Then the network equipment can be with The protocol header example that in-degree in the second network protocol figure is 0 is determined as to the second protocol head of next group of memory space to be allocated Example collection, so that the network equipment can be according to using to the first protocol header example of each of first protocol header example collection Processing mode each second protocol head example in the second protocol head example collection is handled, for the second protocol head Example collection distributes second communal space, and generates the solution of each second protocol head example in the second protocol head example collection Analysis instruction, is below described in detail above-mentioned treatment process.

Optionally, as another embodiment, this method 300 can also include:

The network equipment forms one or more second protocol head examples that in-degree in the second network protocol figure is 0 Set is determined as the second protocol head example collection of memory space to be allocated；

Specifically, the network equipment determines to be allocated in the second network protocol figure deposit after obtaining the second network protocol figure The second protocol head example collection in space is stored up, which may include that one or more in-degrees are 0 Two protocol header examples, which is any protocol header example in the second protocol head set, in first net In network protocol figure, which is next layer of agreement of some protocol header example in the first protocol header example Head example.

For example, if the first Internet protocol figure as shown in Figure 1, the second network protocol figure can be as shown in Figure 5 a, root According to network protocol figure shown in Fig. 5 a, which may include protocol header example H2, protocol header example H3 With protocol header example H4, that is, the second protocol head example can be protocol header example H2, protocol header example H3 and agreement Any protocol header example in head example H4.In first network protocol figure, protocol header example H2, protocol header example H3 and association Discuss next layer of the protocol header example that head example H4 is the protocol header example H1 in the first protocol header set.

The network equipment determines second communal space, and second communal space is for storing the second protocol head example collection Each of the second protocol head example；

After determining the second protocol head example collection, which is determined using processing method similar in S320 Second communal space, second communal space are used to store each second protocol head example in the second protocol head set.

For example, for the second network protocol figure shown in Fig. 5 a, the network equipment is protocol header example H2, protocol header is real The second protocol head example collection of example H3 and protocol header example H4 composition determines second communal space.

What the network equipment generated each second protocol head example second analyzes the instruction, wherein this second is analyzed the instruction It is used to indicate when the network equipment receives the message including the second protocol head example, which is stored To second communal space；

After second communal space for determining the second protocol head example collection, the network equipment is using similar in S330 Processing method, generate each second protocol head example second analyze the instruction, this second analyzes the instruction and be used to indicate in the net When network equipment receives the message including the second protocol head example, by second protocol head example storage to the second shared sky Between.

For example, the second protocol head example collection includes protocol header example H2, protocol header example H3 and protocol header example H4, So when the received message of the network equipment includes protocol header example H2, which can be stored the protocol header example H2 To second communal space, or when received message includes protocol header example H3 (at this point, can not include association in the message Discuss head example H2 and protocol header example H4), which can store the protocol header example H3 and arrive second communal space, Protocol header example H3 storage can be arrived second communal space by the way of cover type storage by the network equipment, that is, Using by the way of being stored before rear storage is covered on, or this second can also be shared before storing protocol header example H3 Then clear space stores the protocol header for example, the corresponding register of second communal space can first be initialized again Example H3, the storage mode that the embodiment of the present application uses protocol header example is with no restriction.

It should be understood that the first protocol header example is any protocol header example in the first protocol header example collection, this One analyzes the instruction analyzing the instruction for the first protocol header example in the first protocol header example collection, that is to say, that first solution Analysis instruction can serve to indicate that analyzing the instruction for any one protocol header example in the first protocol header example collection；Equally Ground, for the second protocol head example and this second to analyze the instruction also be such.

The network equipment is by each of second protocol head example collection second protocol head example from second network The oriented edge contract deleted, and will connect in the second network protocol figure with each second protocol head example in protocol figure.

It should be understood that the layer for the network protocol figure that the execution number of step S310~S340 can be supported according to the network equipment Number determines that, if the number of plies of the network protocol figure is N, step S310~S340 can recycle execution n times, in the n times In implementation procedure, N-1 new network protocol figures can be generated, for example, if network protocol figure such as Fig. 1 that the network equipment is supported Shown, i.e. the maximum number of plies of the network protocol of network equipment support is 5 layers, then step S310~S340 can be recycled and be held Row 5 times, in this 5 implementation procedures, four kinds of network protocol figures as shown in Fig. 5 a to Fig. 5 d can be generated.

Optionally, if this deletes each second protocol head example in the second network protocol figure, and by the second network After the oriented edge contract connecting in protocol figure with each second protocol head example, there are also do not locate in the second network protocol figure The protocol header example of reason, the network equipment can be real to untreated protocol header using processing method similar in S310~S340 Example is handled, and until all distributing the corresponding communal space for all protocol header examples in network protocol figure, and generates phase That answers analyzes the instruction.So when the network equipment receives the message including the protocol header example in network protocol figure, the network Equipment can analyzing the instruction according to the protocol header example, by the protocol header example storage to it is allocated be used to store the association Discuss the communal space of head example.

Fig. 4 shows the schematic flow chart of the method 400 of the storage protocol header according to the embodiment of the present application, below with reference to The method 400 of the storage protocol header of the embodiment of the present application is discussed in detail in network protocol figure shown in Fig. 1, Fig. 5 a~Fig. 5 d.

S401, the network equipment determine the protocol header example collection for the memory space to be allocated that in-degree is 0 in network protocol figure；

Optionally, it may be multiple that the number for the protocol header example that in-degree is 0, which can be 1,.

For example, the number for the protocol header example that in-degree is 0 is 1 for network protocol figure shown in FIG. 1, that is, it is located at described The protocol header example H1 of network protocol figure top；Therefore, the protocol header example collection of the memory space to be allocated only includes The protocol header example H1.And for network protocol figure shown in Fig. 5 a, the number for the protocol header example that in-degree is 0 is 3, respectively It is protocol header example H2, protocol header example H3 and protocol header example H4；Therefore, the protocol header example of the memory space to be allocated Collection is combined into the set of the protocol header example H2, protocol header example H3 and protocol header example H4.

S402, the network equipment are that the protocol header example collection determines the communal space；

Optionally, if the number for the protocol header example that in-degree is 0 is 1, the size of the communal space can be the protocol header The size of example or fixed bit wide.By taking network protocol figure shown in FIG. 1 is first network protocol figure as an example, which is Protocol header example H1 distributes the first communal space R1.Optionally, the size of first communal space can be the protocol header example The size (for example, 16 bits or 32 are than top grade) of the space occupied, or the offset of protocol header example in messages Bit wide (for example, being fixed as 4 bits or 5 than top grade), the embodiment of the present application to this with no restriction.For example, if the protocol header is real Example H1 the space occupied is 64 bits, and the offset of protocol header example H1 in messages is 16 bits, then this is first shared The size of space R1 can be 64 bits or 16 bits.

Optionally, if the number for the protocol header example that in-degree is 0 is greater than 1, the size of the communal space can be multiple The size of longest protocol header example the space occupied in protocol header example, or may be protocol header example in messages Offset bit wide, the embodiment of the present application to this with no restriction.

For the network protocol figure shown in Fig. 5 a is the second network protocol figure, which is the protocol header example The set of H2, protocol header example H3 and protocol header example H4 distribute the second communal space R2, and the size of the second communal space R2 can Think the size of the longest protocol header example in protocol header example H2, protocol header example H3 and protocol header example H4, or Or the bit wide of a fixed offset, the embodiment of the present application to this with no restriction.

Although should be understood that each protocol header example offset in messages it is different (for example, for 16 bits, 32 bits or 64 bits), but the bit wide of the offset of each protocol header example in messages is a fixed value, for example, the offset Bit wide can compare top grade for 7 bits or 8.

It should also be understood why can be by protocol header example H2, protocol header example H3 and these three associations of protocol header example H4 View head example is shared to be stored in second communal space, is because these three protocol header examples will not be same in a message When exist, that is to say, that if the heading format of message is second in Fig. 2 there are protocol header example H2 in message Format, i.e., the protocol header example for including in the message are protocol header example H1, protocol header example H2, protocol header example H7 and agreement Head example H8, therefore protocol header example H3 and protocol header example H4 is not present, similarly, for protocol header example H3 and protocol header Example H4 is also such.

Fig. 6 shows network protocol figure shown in FIG. 1 under the method for salary distribution of above-mentioned two communal space, and the communal space is big Small example.Wherein, the memory space of protocol header example H1 is the first communal space R1.Protocol header example H2, protocol header The memory space of example H3 and protocol header example H4 are the second communal space R2.The protocol header example H5's and protocol header example H6 Memory space is third communal space R3.The memory space of protocol header example H7 is the 4th communal space R4.The protocol header example The memory space of H8 is the 5th communal space R5.As shown in fig. 6, the size of each communal space is same in the method for salary distribution one The size of longest protocol header example the space occupied in one protocol header example collection, for example, protocol header example H2, protocol header is real The size of the second communal space R2 of example H3 and protocol header example H4 is the size of protocol header example H3 the space occupied, protocol header The size of the third communal space R3 of example H5 and protocol header example H6 is the size of protocol header example H5 the space occupied.Dividing With in mode two, equal in magnitude, the bit wide of the offset all for protocol header example in messages of each communal space.

The method of the storage protocol header of the embodiment of the present application, by the way that different protocol header example allocations is shared empty to one Between store, to reduce occupancy of the protocol header example to memory space of storage, improve the memory space of the network equipment Service efficiency can store more protocol header examples for an equal amount of memory space, therefore, can support more complicated net Network protocol figure.

It is to be flowed after the protocol header example collection that the in-degree in network protocol figure is 0 determines the communal space in the network equipment Journey proceeds to S403；

S403, the network equipment are that each protocol header example generation in protocol header example collection analyzes the instruction accordingly；

For example, being the shared sky of protocol header example H1 distribution first in the network equipment for network protocol figure shown in FIG. 1 Between after R1, what which generated protocol header example H1 analyzes the instruction B1, this, which analyzes the instruction B1 and is used to indicate the network, sets For after receiving the message including protocol header example H1, which is stored to the first communal space R1.

Alternatively, for network protocol figure shown in Fig. 5 a, for protocol header example H2, protocol header example H3 and protocol header After example H4 distributes the second communal space R2, the network equipment generate protocol header example H2 to analyze the instruction B2, protocol header real Example H3 analyze the instruction B3 and protocol header example H4 analyze the instruction B4.The network equipment is being received including protocol header example It, can be according to the instruction for analyzing the instruction B2, by the protocol header example H2 storage in the message to the second shared sky when the message of H2 Between R2 or the network equipment when receiving the message including protocol header example H3, can be according to the instruction for analyzing the instruction B3, will Protocol header example H3 storage in the message is being received to the second communal space R2 or the network equipment including protocol header example When the message of H4, according to the instruction for analyzing the instruction B4, by the protocol header example H4 storage in the message to the second communal space R2.

S404, the network equipment delete each protocol header example in the protocol header example collection in network protocol figure, and The directed edge being connect in network protocol figure with each protocol header example.

For example, the network equipment analyzes the instruction B1 generation protocol header example H1's for network protocol figure shown in FIG. 1 Afterwards, protocol header example H1 is deleted, and with directed edge (including < protocol header example H1, the protocol header of the H1 connection of protocol header example Example H2>,<protocol header example H1, protocol header example H3>and<protocol header example H1, protocol header example H4>), generate at this time New network protocol figure is network protocol figure shown in Fig. 5 a.

Alternatively, the network equipment is generating protocol header example H2, protocol header example for network protocol figure shown in Fig. 5 a After the analyzing the instruction of H3 and protocol header example H4, delete protocol header example H2, protocol header example H3 in network protocol figure and Protocol header example H4, and connect with protocol header example H2, protocol header example H3 and protocol header example H4 directed edge (including <protocol header example H2, protocol header example H7>,<protocol header example H3, protocol header example H5>and<protocol header example H4, protocol header Example H6 >), the new network protocol figure generated at this time is network protocol figure shown in Fig. 5 b.

S405 judges whether there is also protocol header examples in network protocol figure, and if it exists, process proceeds to S401, otherwise, Process terminates.

For example, there is also the protocol header examples of unallocated memory space in protocol figure for the network protocol figure in Fig. 5 a (protocol header example H2~protocol header example H8), at this point, process re-starts S401.It is executed in S401~S405 by circulation Operation, sequentially generate Fig. 5 b, Fig. 5 c, the network protocol figure in Fig. 5 d, so far, no-protocol head example in network protocol figure, Process terminates.

After having executed above-mentioned steps, each protocol header example in the network protocol figure in Fig. 1 is assigned with memory space, And it generates and analyzes the instruction accordingly.Specifically, the memory space of protocol header example H1 is the first communal space R1, the agreement The memory space of head example H2, protocol header example H3 and protocol header example H4 are the second communal space R2, protocol header example H5 Memory space with protocol header example H6 is third communal space R3, and the memory space of protocol header example H7 is the 4th communal space The memory space of R4, protocol header example H8 are the 5th communal space R5, protocol header example H1~protocol header example H8 parsing Instruction is respectively to analyze the instruction B1~analyze the instruction B8.

Therefore, the method for the storage protocol header of the embodiment of the present application is stored in together by sharing multiple protocol header examples In one communal space, therefore reduce storage protocol header example to the occupancy of memory space, hence for same storage sky Between, more protocol header examples can be stored, and then can support more complicated network protocol figure.
