The embodiment of the present invention provides a kind of business chain processing method, for the network equipment, as in figure 2 it is shown, the method includes:

Step 101, the service priority field obtaining business chain are (English: ServicePriorityField；It is called for short: SPF) value, this spf value is for indicating the grade of service of user, the default network of user associates with business chain, business chain includes at least one Service Source pond, each Service Source pond includes at least two service equipment, the service ability in each Service Source pond is the service ability sum of the service equipment in Service Source pond, at least one Service Source pond of network device management business chain。

Step 102, inquiring about the corresponding relation of spf value and scale factor according to the spf value of business chain, scale factor corresponding to the spf value of business chain inquiry obtained is as the scale factor of business chain。

Step 103, using the long-pending offer ability as first service resource pool of the service ability of the scale factor of business chain and first service resource pool, first service resource pool be the business chain of network device management Service Source pond in arbitrary Service Source pond。

Step 104, determining that in first service resource pool n service equipment carries out the offer serviced according to offer ability, n is the integer more than or equal to 1。

In sum, the business chain processing method that the embodiment of the present invention provides, owing to the network equipment can obtain the scale factor of business chain according to the spf value of the grade of service of instruction user, thus obtaining the offer ability in Service Source pond, finally determine the service equipment that service is provided in Service Source pond for the message of user, the service quality making the message of user can effectively be distinguished, therefore, in the process to the message offer service of different user, ensure that business chain provides different service quality to different user, the offer of service is pointed。

It should be noted that the business chain processing method that the embodiment of the present invention provides, it is possible to being applied to the network equipment, this network equipment can be management node, it is also possible to for switch。

On the one hand, the network equipment can be management node, when the network equipment is for management node, and all Service Source ponds of management node administration business chain, as it is shown on figure 3, this business chain processing method includes:

Step 201, when user's configuration service chain, management node generates initial configuration, and this initial configuration includes: the corresponding relation of user and spf value, the corresponding relation of spf value and scale factor, each Service Source pond index in business chain mark and business chain。

Further, as shown in Figure 4, step 201 specifically may include that

Step 2011, management node set up the corresponding relation of user and spf value。

Management node, according to service class corresponding to different user, distributes the spf value of correspondence for each user, and service class corresponding to user is more high, and the spf value for user's distribution is more big, sets up the corresponding relation of user and spf value according to the spf value of distribution。It should be noted that the corresponding ID of each user is (English: Identity；It is called for short: ID), this ID has uniqueness, say, that the corresponding user of each ID。Example, if there being four users, it is user A respectively, user B, user C and user D, manager is I by user interface to the user A service class configured, it is IV to the service class of user B configuration, it is II to the service class of user C configuration, it is III to the service class of user D configuration, wherein, the grade of each service class by order is from high to low: I > II > III > IV, that is, the grade of the service class that each user is corresponding by order is from high to low: user A > user C > user D > user B, therefore, management node can be 4 for the spf value of user A distribution, spf value for user B distribution is 1, spf value for user C distribution is 3, spf value for user D distribution is 2, the user established is as shown in table 1 with the corresponding relation of spf value。

Table 1

ID	User	Spf value
			ID1	User A	4
ID2	User B	1
			ID3	User C	3
ID4	User D	2

Step 2012, management node set up the corresponding relation of spf value and scale factor。

After management node establishes the corresponding relation of user and spf value, resettle the corresponding relation of spf value and scale factor, the corresponding scale factor of each spf value, this scale factor represents that each Service Source pond can account for the percentage ratio of the total service ability of Service Source Chi for the service ability that the message of user corresponding to a certain spf value provides, spf value is more big, and the scale factor that spf value is corresponding is more big。As shown in Figure 5, assume that a certain bar business chain E is jumped service (P1, P2 ... Pm) composition by the m altogether such as fire wall, intrusion detection, optimizing application and load balancing, wherein, m >=1, each jumping service is equivalent to a Service Source pond, therefore, this business chain has m Service Source pond, deploys multiple identical service equipment (S in each Service Source pond₁、S₂……S_Pin), wherein, Pin is total number of the service equipment in i-th Service Source pond, and 0 < i < m+1, and the multiple identical service equipment disposed in each Service Source pond is used for realizing load balancing and highly reliable characteristic。For table 1, assume that the spf value that management node is set up is as shown in table 2 with the corresponding relation of scale factor, in m Service Source pond of this business chain, each Service Source pond can account for the percentage ratio of the total service ability of Service Source Chi for the service ability that the message of user A provides is X1, it is X2 that the service ability provided for the message of user B accounts for the percentage ratio of the total service ability of Service Source Chi, it is X3 that the service ability provided for the message of user C accounts for the percentage ratio of the total service ability of Service Source Chi, it is X4 that the service ability provided for the message of user D accounts for the percentage ratio of the total service ability of Service Source Chi, due to SPF (A) > SPF (C) > SPF (D) > SPF (B), so there being X1 > X3 > X4 > X2。It is to say, spf value corresponding to user B is minimum, scale factor corresponding for user B is also just minimum, such as X1=80%, X3=65%, X4=40%, X2=10%。

Table 2

ID	User	Spf value	Scale factor
				ID1	User A	4	X1
ID2	User B	1	X2
				ID3	User C	3	X3
ID4	User D	2	X4

Step 2013, when user's configuration service chain, management node be business chain distribution services chain mark, in business chain each Service Source Chi Fenpeiziyuanchi index。

Management node, by identifying to business chain distribution services chain, distinguishes different business chain, finally determines that the message which bar business chain is user provides service。This business chain mark has uniqueness, say, that the corresponding business chain of each business chain mark。

Owing to each business chain includes at least one Service Source pond, therefore, management node needs to distribute corresponding resource pool index to each Service Source pond in every business chain, example, user 1 configuration service chain 1, and the business chain for business chain 1 distribution is designated ID01, it is assumed that business chain 1 comprises Service Source pond A, and the resource pool index for the Service Source pond A distribution in business chain 1 is 1；User 2 configuration service chain 2, and the business chain for business chain 2 distribution is designated ID02, assume that business chain 2 also comprises Service Source pond A, and the resource pool index for the Service Source pond A distribution in business chain 2 is 2, therefore can uniquely be defined as message according to business chain mark and resource pool index provides the respective service resource pool of service。It should be noted that, the distribution method of the resource pool index in each business chain can be sequence distribution method, namely management node is the resource pool index of first Service Source pond distribution in this business chain is 1, resource pool index for second Service Source pond distribution in this business chain is 2, resource pool index for the 3rd Service Source pond distribution in this business chain is 3, below the like, until all Service Source ponds in this business chain are all assigned to resource pool index。

Step 202, management node obtain the spf value of business chain。

Spf value is for indicating the grade of service of user, the default network of user associates with business chain, business chain includes at least one Service Source pond, each Service Source pond includes at least two service equipment, the service ability in each Service Source pond is the service ability sum of the service equipment in Service Source pond, at least one Service Source pond of business chain described in network device management, example, Service Source pond can be as shown in Figure 5。

Further, as shown in Figure 6, step 202 specifically may include that

Step 2021, management node receive the related information that user interface sends。

Related information includes: ID, and the default network of related information instruction user associates with business chain。

Example, in table 1, the message of user A is to transmit the message to network N 2 from network N 1, and the ID of user A is ID1, that be assumed to be user A offer service is business chain E, so user interface is associated to the default network (network N 1 and network N 2) of the message that content is user A indicated by the related information of management node transmission with business chain E, and business chain E is by business chain mark instruction, and user is indicated by ID ID1。

Step 2022, management node inquire about the corresponding relation of user and spf value according to ID, will inquire about spf value corresponding to the ID the obtained spf value as business chain。

For table 1, inquiring about the corresponding relation of user A and spf value according to ID ID1, obtaining spf value corresponding for user A is 4, and the spf value then inquiry obtained is as the spf value of the business chain E providing service, and the spf value namely providing the business chain E of service is 4。

Step 203, management node determine the offer ability of first service resource pool according to the spf value of initial configuration and business chain。

Further, as it is shown in fig. 7, step 203 specifically may include that

Step 2031, management node inquire about the corresponding relation of spf value and scale factor according to the spf value of business chain, and scale factor corresponding to the spf value of business chain inquiry obtained is as the scale factor of business chain。

Example, as shown in Table 1 and Table 2, the spf value of business chain E providing service for the message of user A is 4, and the scale factor corresponding to spf value corresponding to user A is X1, so the scale factor corresponding to the spf value of business chain E is X1, using the X1 scale factor as business chain E。

Step 2032, management node are using the long-pending offer ability as first service resource pool of the scale factor of business chain with the service ability of first service resource pool。

This first service resource pool be the business chain of network device management Service Source pond in arbitrary Service Source pond。For above-mentioned business chain E, the service ability of first service resource pool is the service ability sum of the service equipment in the business chain E arbitrary Service Source pond included。If a certain Service Source pond SP in business chain E includes five service equipments, the service ability of these five service equipments respectively E₁₁、E₁₂、E₁₃、E₁₄And E₁₅, then the service ability of Service Source pond SP can be expressed as S_th=E₁₁+E₁₂+E₁₃+E₁₄+E₁₅, and owing to the scale factor of business chain E is X1, therefore Service Source pond SP can be expressed as P for the offer ability of message_th=(E₁₁+E₁₂+E₁₃+E₁₄+E₁₅)*X1。

According to offer ability, step 204, management node determine that in first service resource pool n service equipment carries out the offer serviced, n is the integer more than or equal to 1。

Further, step 204 specifically may include that

A, obtaining the service ability sum of x service equipment in the service equipment of first service resource pool, x is the integer more than or equal to 1。

If the service ability sum of x service equipment of b is less than the ability of offer, updates x and make the x after updating equal to former x+1, repeat above-mentioned summation process, until the service ability sum of x service equipment is more than or equal to the ability of offer。

C, when the service ability sum of x service equipment is equal to offer ability, using x service equipment as n service equipment。

D, when x service equipment service ability sum more than provide ability, in x-1 service equipment and x service equipment, determine that the immediate service equipment of service ability sum is as n service equipment。

In step 203, the Service Source pond SP of business chain E, Service Source pond SP are P for the offer ability of message_th, the service ability respectively E of five service equipments that Service Source pond SP includes₁₁、E₁₂、E₁₃、E₁₄And E₁₅, then according to providing ability P_thThe process determining the offer that n service equipment carry out servicing in the SP of Service Source pond can be: first obtains the service ability E of first service equipment in the service equipment of Service Source pond SP₁₁If, E₁₁Less than providing ability P_th, then judge the service ability sum E of first service equipment and second service equipment₁₁+E₁₂Whether less than providing ability P_thIf, E₁₁+E₁₂Less than P_th, then judge the service ability sum E of first service equipment, second service equipment and the 3rd service equipment₁₁+E₁₂+E₁₃Whether less than providing ability P_thIf, E₁₁+E₁₂+E₁₃Less than P_th, whether continue the service ability sum judging front four service equipments less than providing ability P_th；If E₁₁+E₁₂+E₁₃Equal to P_th, then another n is equal to 3, and first three service equipment namely provides the service equipment of service as the message finally giving user；If E₁₁+E₁₂+E₁₃More than P_th, calculate the service ability sum E of first service equipment and second service equipment₁₁+E₁₂, first service equipment, the service ability sum E of second service equipment and the 3rd service equipment₁₁+E₁₂+E₁₃, will be closest to P_thProvide, as the message of the final user of giving, the service equipment serviced with service equipment corresponding to value。

Step 205, management node generate initial metadata, and initial metadata includes the first resource pool index of the spf value of business chain, business chain mark and business chain。

When the message of user is when flowing through the business chain providing service, in order to identify and follow the tracks of message forwarding status information in this business chain, ensure the message correct forwarding in business chain, message needs to carry metadata, therefore management node needs first to generate initial metadata, and this initial metadata includes the first resource pool index of the spf value of the business chain that message flows through, business chain mark and business chain。Example, the message of user A is associated with business chain E, business chain E is provided with three Service Source ponds, and the first resource pool of business chain index is 1, then generate the first resource pool index 1 that initial metadata includes the business chain of the spf value of business chain E, the mark of business chain E and business chain E。

In order to realize the load balancing of business chain, this initial metadata can also include the Hash factor, for identifying different messages, especially by hash algorithm, the five-tuple of message message is carried out Hash operation and obtains the Hash factor。Wherein, hash algorithm refers in a bigger message five-tuple compound mapping to another less set, the relatively data representation Hash factor in small set, example, hash algorithm can be modulus remainder method, is about to be not more than several p of the data amount check of message five-tuple set except remainder obtained after each message five-tuple is as the Hash factor；It is (English: InternetProtocol that five-tuple refers to source net association；It is called for short: IP) address, purpose IP address, source port number, destination slogan and protocol type。According to the ratio of the service ability of each service equipment in the Hash factor and service resource pool, it is determined which service equipment is responsible for processing which message, in order to management node sends to the switch providing the service equipment of service to connect and forwards configuration。Example, the message five-tuple of the user A in table 2 is 1-100 through the Hash factor that hash algorithm obtains, this message then can be divided into 100 parts of threads, each thread is likely to corresponding hundreds and thousands of messages, assume that in the Service Source pond SP of the business chain E in step 203, five service equipments have two service equipments to be determined for providing service, and the ratio of the service ability of the two service equipment is 1: 1, so first service equipment processes the Hash factor is the message of 1-50, and it is the message of 51-100 that second service equipment processes the Hash factor；If the ratio of the service ability of the two service equipment is 3: 1, then it is the message of 1-75 that first service equipment processes the Hash factor, it is the message of 76-100 that second service equipment processes the Hash factor。As can be seen here, business chain metadata introduces Hash and can the forwarding that sends to switch of streamlining management node configure because of son field, assume have 200 messages to be mapped to the same Hash factor, i.e. corresponding 200 messages of a thread, for these 200 messages, management node can send one to switch and forward configuration；Without the Hash factor, then management node needs to send 200 forwarding configurations to realize the forwarding of different message to switch。

It should be noted that, according to the ratio of the service ability of each service equipment in the Hash factor and service resource pool, can determine which service equipment is responsible for processing which message according to the method for above-mentioned direct distribution, it is also possible to the method for cycle assignment determines which service equipment is responsible for processing which message in order。Example, the message five-tuple of the user A in table 2 is 1-10 through the Hash factor that hash algorithm obtains, this message then can be divided into 10 parts of threads, each thread is likely to corresponding hundreds and thousands of messages, assume that in the Service Source pond SP of the business chain E in step 203, five service equipments are FW1 respectively, FW2, FW3, FW4 and FW5, and FW1, FW2 and FW3 is determined for providing service, FW1, the ratio of the service ability of FW2 and FW3 is 1: 1: 1, so FW1 processes the Hash factor is the message of 1, it is the message of 2 that FW2 processes the Hash factor, it is the message of 3 that FW3 processes the Hash factor, then making FW1 process the Hash factor again is the message of 4, it is the message of 5 that FW2 processes the Hash factor, it is the message of 6 that FW3 processes the Hash factor, circulation successively below is analogized。Same, if the ratio of the service ability of FW1, FW2 and FW3 is 1: 3: 2, so FW1 processes the Hash factor is the message of 1, it is the message of 2-4 that FW2 processes the Hash factor, it is the message of 5-6 that FW3 processes the Hash factor, then making FW1 process the Hash factor again is the message of 7, and it is the message of 8-10 that FW2 processes the Hash factor。

Step 206, management node send classification configurations to grader, and classification configurations includes initial metadata。

Grader is as the entrance of message, being responsible for message is classified, by message redirecting to business chain, according to message information, grader is for determining which business chain this message flows through, the initial metadata of business chain is injected again, to ensure the message correct forwarding on associated services chain for user's message。

Step 207, management node generate the metadata that the first switch is corresponding, and the metadata that the first switch is corresponding includes the resource pool index of service equipment correspondence in business chain that the spf value of business chain, business chain mark and the first switch connect。

First switch is any one switch in each switch that n service equipment connects。It should be noted that each Service Source pond can corresponding same switch, it is also possible to corresponding different switches。Example, the message of user A is associated with business chain E, in step 203, business chain E is provided with three Service Source ponds, the index in first Service Source pond is 1, switch corresponding to first Service Source pond is switch 1, the index in second Service Source pond is 2, switch corresponding to second Service Source pond is switch 2, the index in the 3rd Service Source pond is 3, 3rd switch that Service Source pond is corresponding is switch 3, so management node can generate switch 1 respectively, the metadata of switch 2 and switch 3 correspondence, wherein, the metadata of switch 1 correspondence includes the spf value of business chain E, the service equipment that the mark of business chain E and switch 1 connect is first Service Source pond index 1 of correspondence on business chain E；The metadata of switch 2 correspondence includes the spf value of business chain E, the mark of business chain E and the service equipment of switch 2 connection and indexes 2 in second Service Source pond of correspondence on business chain E；The metadata of switch 3 correspondence includes the spf value of business chain E, the mark of business chain E and the service equipment of switch 3 connection and indexes 3 in the 3rd Service Source pond of correspondence on business chain E。

Further, in order to realize the load balancing of business chain, the metadata of switch 1, switch 2 and switch 3 correspondence can also include the Hash factor。

Step 208, management node send to the first switch and forward configuration, forward the port that the service equipment providing service with the first switch in the service equipment of the metadata corresponding in business chain of service equipment that configuration includes connecting, the first switch connection is corresponding。

Example, in step 207, the port numbers that port numbers is 2, S12 correspondence switches 1 that service equipment is S11 and S12, S11 correspondence switch 1 providing service in the service equipment that switch 1 connects is 3；The port numbers that port numbers is 2, S22 correspondence switches 2 that service equipment is S21 and S22, S21 correspondence switch 2 providing service in the service equipment that switch 2 connects is 4；The port numbers that port numbers is 4, S32 correspondence switches 3 that service equipment is S31 and S32, S31 correspondence switch 3 providing service in the service equipment that switch 3 connects is 6。Therefore, management node sends to switch 1 and forwards configuration, this forwarding configuration includes the metadata corresponding on business chain E for S11 and S12 connected with switch 1, the service equipment that switch 1 connects provides two ports that the service equipment of service is corresponding: No. 2 and No. 3 ports, management node sends to switch 2 and forwards configuration, this forwarding configuration includes the metadata corresponding on business chain E for S21 and S22 connected with switch 2, the service equipment that switch 2 connects provides two ports that the service equipment of service is corresponding: No. 2 and No. 4 ports, management node sends to switch 3 and forwards configuration, this forwarding configuration includes the metadata corresponding on business chain E for S31 and S32 connected with switch 3, the service equipment that switch 3 connects provides two ports that the service equipment of service is corresponding: No. 4 and No. 6 ports。

Step 209, determining message need to through business chain, grader according to classification configurations, switch according to forwarding configuration to realize the process of message。

Concrete, grader is according to classification configurations, switch according to the process forwarding configuration to realize Message processing can be: when the categorized device of message flow, grader meeting analytic message, obtain the business chain mark that this message carries, in grader, the classification configurations that this message is corresponding is determined according to this business chain mark, grader can obtain the initial metadata in this classification configurations, and inject in message, grader indexes the switch being forwarded to by user's message corresponding to first Service Source pond according to the first resource pool of the business chain in initial metadata, for step 207, switch corresponding to first Service Source pond is switch 1；After switch 1 receives message, the metadata of the initial metadata in message and switch 1 correspondence is mated, owing to the initial metadata in message includes the spf value of business chain E, the mark of business chain E and the first resource pool index 1 of business chain E, the metadata of switch 1 correspondence includes the spf value of business chain E, first corresponding on business chain E for S11 and S12 Service Source pond index 1 that the mark of business chain E and switch 1 connect, therefore, initial metadata and the metadata of switch 1 correspondence in message match, switch 1 is forwarded the packet to service equipment S11 by No. 2 ports, switch 1 is forwarded the packet to service equipment S12 by No. 3 ports。It should be noted that, message is forwarded by the ratio that switch 1 is the service ability of the value according to the Hash factor in initial metadata and S11, S12, example, the Hash factor value assuming message is 1-100, the ratio of the service ability of S11 and S12 is 1: 1, so the message that the Hash factor is 1-50 is forwarded to S11 by switch 1, and the message that the Hash factor is 51-100 is forwarded to S12。Message after process is forwarded to switch 1 by S11 and S12 again, now, switch 1 updates the resource pool index in message initial metadata, new metadata includes the spf value of business chain E, second corresponding on business chain E for S21 and S22 Service Source pond index 2 that the mark of business chain E and switch 2 connect, the message that switch 2 desampler 1 sends, and the metadata of metadata new in message and switch 2 correspondence is mated, if matched, switch 2 is then forwarded the packet to S21 and S22 according to the sub-factor in the Kazakhstan in metadata by No. 2 and No. 4 ports, message after process is forwarded to switch 2 by service equipment, now, switch 2 updates the resource pool index in message metadata, this new metadata includes the spf value of business chain E, the index 3 in the 3rd corresponding on business chain E for S31 and the S32 Service Source pond that the mark of business chain E and switch 3 connect, the message that switch 3 desampler 2 sends, and the metadata of metadata new in message and switch 3 correspondence is mated, if matched, switch 3 is then forwarded the packet to S31 and S32 according to the sub-factor in the Kazakhstan in metadata by No. 4 and No. 6 ports, message after process is forwarded to switch 3 by service equipment, so far, business chain just completes the process to message, finally, message is forwarded to destination host。

Example, assume that business chain processes structural representation as shown in Figure 8, the business chain L providing service for user 1 is made up of FW and IPS double bounce service i.e. two Service Source ponds, in order to realize load balancing and highly reliable characteristic, four same services equipment respectively IPS1, IPS2, IPS3 and the IPS4 disposed in four same services equipment respectively FW1, FW2, FW3 and the FW4 disposed in FW service, IPS service。No. 2 of switch 2, No. 4, No. 6 and No. 8 ports connect FW1, FW2, IPS1 and IPS2 respectively, and No. 2 of switch 3, No. 4, No. 6, No. 8 ports connect FW3, FW4, IPS3 and IPS4 respectively。The information of each service equipment is by managing node maintenance, and this information includes the information such as the port numbers of the device type of service equipment, service ability, service equipment place switch and the connected switch of service equipment。Assume that user 1 has two business networks, respectively network A and network B, network A enters to the message of network B from switch 1 (grader), flow out from switch 4, user 1 wants the message of network A to network B through business chain L, the message being user 1 by business chain L provides service, and the service ability that the service ability in FW Service Source pond is A1, IPS Service Source pond is A2。

According to step 201, when user 1 configuration service chain L, management node generates initial configuration, assume that the ID of user 1 correspondence is ID1, the spf value of user 1 correspondence is SPF1, the scale factor that spf value is corresponding is Y1, business chain L is designated chain-1, the index in FW Service Source pond is 1, the index in IPS Service Source pond is 2, then initial configuration includes the corresponding relation of user 1 and SPF1, the corresponding relation of SPF1 and Y1, business chain L identifies the index 1 in chain-1, FW Service Source pond and the index 2 in IPS Service Source pond。

According to step 202, management node obtains the spf value of business chain L, specifically may include that management node receives the related information that user interface sends: ID ID1, the default network (network A and network B) of related information instruction user 1 associates with business chain L；Management node inquires about the corresponding relation of user 1 and spf value according to ID ID1, and SPF1 inquiry obtained is as the spf value of business chain L。

According to step 203, management node determines the offer ability of first service resource pool according to the spf value of initial configuration and business chain。Management node is using the long-pending A1*Y1 of the service ability in the scale factor Y1 of business chain L and the FW Service Source pond offer ability as FW Service Source pond, using the long-pending A2*Y1 of the service ability in the scale factor Y1 of business chain L and the IPS Service Source pond offer ability as IPS Service Source pond。

According to step 204, according to the offer ability in FW and IPS Service Source pond, management node determines that in two Service Source ponds which service equipment carries out the offer serviced, assume that the service equipment determined in FW Service Source pond is FW1 and FW2, the service equipment determined in IPS Service Source pond is IPS3 and IPS4, and the ratio of the service ability of FW1 and FW2 is 1: 1, the ratio of the service ability of IPS3 and IPS4 is 3: 1。

According to step 205, management node generates spf value SPF1, the business chain L of initial metadata: business chain L and identifies index 1 and the Hash factor in chain-1, FW Service Source pond。Assume that the Hash factor obtained after the message five-tuple of user 1 is carried out Hash operation is 1-100。

According to step 206, management node sends classification configurations to grader and switch 1, and classification configurations includes initial metadata。

According to step 207, management node generates the metadata of switch 2 correspondence: SPF1, chain-1, FW Service Source pond index 1 and Hash factor 1-100；Management node generates the metadata of switch 3 correspondence: SPF1, chain-1, FW Service Source pond index 1 and Hash factor 1-100。

According to step 208, management node sends to switch 2 and switch 3 and forwards configuration。

According to step 209, determining that message need to through business chain L, switch 1 configures, according to forwarding, the process realizing message according to classification configurations, switch 2 and switch 3。

Wherein, the process of the process that switch 1 realizes message according to classification configurations is: for the network A of user 1 to the message of network B, injecting the initial metadata of business chain L, switch 1 carries the message of initial metadata and is forwarded to switch 2。

Switch 2 according to the process of the process forwarding configuration to realize message is:

1) message is received from switch upstream Interface, owing to the metadata on the initial metadata in message and switch 2 matches, therefore business chain L in initial metadata is designated chain-1 by switch 2, the index in FW Service Source pond is 1, the spf value of business chain L is SPF1, the Hash factor is the message of 1-50, is forwarded the packet to FW1 by No. 2 ports。

2) message is received from switch upstream Interface, owing to the metadata on the initial metadata in message and switch 2 matches, therefore business chain L in initial metadata is designated chain-1 by switch 2, the index in FW Service Source pond is 1, the spf value of business chain L is SPF1, the Hash factor is the message of 51-100, is forwarded the packet to FW2 by No. 4 ports。

3) from the service equipment FW1 message sent, in its metadata, business chain L is designated chain-1, the index in FW Service Source pond is 1, the spf value of business chain L is SPF1, the Hash factor is 1-50, resource pool index 1 in this message metadata is updated to the index 2 in next Service Source pond and IPS Service Source pond by switch 2, then forwards the packet to switch 3。

4) from the service equipment FW2 message sent, in its metadata, business chain L is designated chain-1, the index in FW Service Source pond is 1, the spf value of business chain L is SPF1, the Hash factor is 51-100, resource pool index 1 in this message metadata is updated to the index 2 in next Service Source pond and IPS Service Source pond by switch 2, then forwards the packet to switch 3。

Switch 3 according to the process of the process forwarding configuration to realize message is:

1) message is received from switch upstream Interface, owing to the metadata in the metadata in message and switch 3 matches, therefore business chain L in metadata is designated chain-1 by switch 3, the index in IPS Service Source pond is 2, the spf value of business chain L is SPF1, the Hash factor is the message of 1-75, is forwarded the packet to service equipment IPS3 by No. 6 ports。

2) message is received from switch upstream Interface, owing to the metadata in the metadata in message and switch 3 matches, therefore business chain L in metadata is designated chain-1 by switch 3, the index in IPS Service Source pond is 2, the spf value of business chain L is SPF1, the Hash factor is the message of 76-100, is forwarded the packet to service equipment IPS4 by No. 8 ports。

3) after IPS3 and IPS4 has processed message, forward the packet again to switch 3, the metadata of switch 3 matching message, the related information according to the business chain of UI Preferences Yu user preset network, the message that business chain L in metadata is designated chain-1 is forwarded to switch 4。

Above-mentioned steps describes the management node as chain of command and provides the mechanism of service based on the dynamic distribution capability resource of the spf value that user is corresponding for user's message, chain of command safeguards the mapping relations of user and spf value, dynamically distribute service equipment for user, it is provided that the load balancing corresponding with the user class of service and highly reliable characteristic。

In sum, the business chain processing method that the embodiment of the present invention provides, owing to management node can obtain the scale factor of business chain according to the spf value of the grade of service of instruction user, thus obtaining the offer ability in Service Source pond, finally determine the service equipment that service is provided in Service Source pond for the message of user, the service quality making the message of user can effectively be distinguished, therefore, in the process to the message offer service of different user, ensure that business chain provides different service quality to different user, the offer of service is pointed。

On the other hand, the network equipment can be switch, the embodiment of the present invention for the first switch, at least one Service Source pond of the first switch management business chain, as it is shown in figure 9, this business chain processing method includes:

Step 401, when user's configuration service chain manage node generate deployment information, this deployment information includes: the corresponding relation of spf value and scale factor, the Service Source pond mark in the Service Source pond that the first switch connects and the corresponding relation of the first each port of switch, the service ability of each service equipment that the first each port of switch connects, and service resource pool mark identifies with business chain, the corresponding relation of Service Source pond index。

Wherein, spf value is as shown in table 2 with the corresponding relation of scale factor。The service ability of each service equipment that the first each port of switch the connects scale factor corresponding with spf value may determine that the offer ability in each Service Source pond, and detailed process is referred to step 203。

It should be noted that, a corresponding unique Service Source pond, each Service Source pond mark, that assumes business chain E is designated IDE, business chain E is to there being three switches, respectively switch 1, switch 2 and switch 3, the Service Source pond that the service equipment that switch 1 connects is corresponding on business chain E is A1, A1 is designated IDA1, the resource pool index of Service Source pond A1 is 1, switch 1 has 8 ports, wherein, No. 2, No. 4, No. 6 and No. 8 ports connect the service equipment in A1, the Service Source pond A1 that so switch 1 connects is as shown in table 3 with switch 1 each port corresponding relation with the mark IDA1 of the A1 that each port of switch 1 switch 1 namely is connected, Service Source pond A1 identifies IDA1 and business chain E and identifies IDE, the corresponding relation of Service Source pond A1 index 1 is as shown in table 4, table 4 identifies IDE according to business chain and resource pool index 1 is uniquely defined as message and provides the respective service resource pool A1 of service。

Table 3

Port numbers	Service Source pond identifies
		2	IDA1
4	IDA1
		6	IDA1

Table 4

Service Source pond identifies	Business chain identifies	Service Source pond indexes
			IDA1	IDE	1

Step 402, management node send deployment information to the first switch。

Step 403, the first switch Service Source pond index according to business chain mark, Service Source pond, in the corresponding relation that Service Source pond mark and business chain mark, Service Source pond index, obtains the Service Source pond mark of first service resource pool。

First service resource pool be the business chain of the first switch management Service Source pond in arbitrary Service Source pond, owing to each Service Source pond can be different at the resource pool index often jumped in business chain, therefore, need by the Service Source pond index of business chain mark, Service Source pond, in the corresponding relation that Service Source pond mark and business chain mark, Service Source pond index, obtain Service Source pond mark。

For table 4, switch 1 identifies IDE according to business chain, and Service Source pond index 1 obtains the resource pool mark of Service Source pond A1 in the corresponding relation of table 4, and this Service Source pond is designated IDA1。

Step 404, the first switch identify the Service Source pond mark in the Service Source pond that inquiry the first switch connects and the corresponding relation of the first each port of switch according to the Service Source pond of first service resource pool, it is determined that the port that first service resource pool is corresponding。

Owing to the Service Source pond of first service resource pool identifies corresponding first service resource pool, therefore which port of corresponding first switch in the Service Source pond of the first switch connection can be determined with the corresponding relation of the first each port of switch according to the Service Source pond mark in the Service Source pond that the first switch connects, in order to the first switch carries out the follow-up forwarding of message by this port。For table 3, the Service Source pond A1 that switch 1 indexes 1 correspondence according to Service Source pond identifies the A1 of IDA1 inquiry switch 1 connection and the corresponding relation of each port of switch 1, it is determined that port corresponding for A1 respectively No. 2, No. 4, No. 6 and No. 8 ports。

The service ability sum of each service equipment that port corresponding in first service resource pool is connected by step 405, the first switch is as the service ability of first service resource pool。

Port corresponding for Service Source pond A1 as shown in Table 3 respectively No. 2, No. 4, No. 6 and No. 8 ports, assume the service equipment respectively SS1 of these four ports connections, SS2, SS3 and SS14, and the service ability of four service equipments respectively P1, P2, P3 and P4, then switch 1 using P1, P2, P3 and P4 sum as the service ability in this Service Source pond。

Step 406, the first switch obtain business chain spf value。

Spf value is for indicating the grade of service of user, the default network of user associates with business chain, business chain includes at least one Service Source pond, each Service Source pond includes at least two service equipment, the service ability in each Service Source pond is the service ability sum of the service equipment in Service Source pond, at least one Service Source pond of network device management business chain, example, the structure in this Service Source pond can be as shown in Figure 5。

Further, as shown in Figure 10, step 406 specifically may include that

Step 4061, reception message, the metadata of message includes business chain mark。

It should be noted that, the upstream Interface of the first switch can be connected with grader, can also connect by switch, grader is as the entrance of user's message, it is responsible for message is classified, by message redirecting to business chain, according to message information, grader is for determining which business chain this message flows through, it is ensured that the message correct forwarding on associated services chain。Switch refers to the switch of each service equipment connected in business chain。

Business chain mark is used for distinguishing different business chain, it may be determined that the message which bar business chain is user provides service, and this business chain mark has uniqueness, say, that the corresponding business chain of each business chain mark。

According to business chain mark, step 4062, the first switch determine that message need to through business chain。

Example, if there are some business chain simultaneously, switch can according to the mark of business chain be defined as active user message provide service business chain be which bar business chain。

Step 4063, the first switch obtain the spf value of business chain in the metadata。

Metadata can be included as user's message the business chain mark of service is provided, it is also possible to including the spf value of business chain, this spf value refers to the spf value that ID is corresponding。

Step 407, the first switch inquire about the corresponding relation of spf value and scale factor according to the spf value of business chain, and scale factor corresponding to the spf value of business chain inquiry obtained is as the scale factor of business chain。

This step is specifically referred to the step 2031 in above-described embodiment。

Step 408, the first switch are using the long-pending offer ability as first service resource pool of the scale factor of business chain with the service ability of first service resource pool。

This step detailed process is referred to the step 2032 in above-described embodiment。

According to offer ability, step 409, the first switch determine that in first service resource pool n service equipment carries out the offer serviced, n is the integer more than or equal to 1。

This step detailed process is referred to the step 204 in above-described embodiment。

Step 410, the first switch select a service equipment in n service equipment and carry out message forwarding。

Further, as shown in figure 11, step 410 specifically may include that

Step 4101, the first switch select a service equipment in n service equipment。

For step 405, assume that the service equipment providing service that switch 1 is determined in resource pool index is for the Service Source pond of 1 according to offer ability is SS1, SS2 and SS4, switch 1 then selects a service equipment to carry out forwarding and the process of message from SS1, SS2 and SS4, it is assumed that the service equipment that switch 1 selects is SS1。

Message is sent to the service equipment selected by step 4102, the first switch。

For step 4101, assume that message five-tuple is 1-100 through the Hash factor that hash algorithm obtains, and the ratio of the service ability of SS1, SS2 and SS4 is 3: 1: 1, then the message that the Hash factor is 1: 60 is forwarded to SS1 by switch 1, in order to the message that the Hash factor is 1: 60 is processed by SS1。

Message is processed by step 4103, the service equipment selected。

For step 4102, the service equipment that switch 1 selects is that the message that the Hash factor is 1: 60 is processed by SS1, SS1, and example, SS1 can be FW, it is also possible to for IPS。

Step 4104, select service equipment to first switch transmission process after message。

Message for step 4103, after the message that the Hash factor is 1: 60 is processed by SS1, after processing to switch 1 transmission。

The resource pool index upgrade of the metadata of the message after process is next resource pool index by step 4105, the first switch。

Next resource pool index is adjacent with the resource pool of metadata index in business chain and is positioned at the resource pool index after the resource pool index of metadata。In order to make message be forwarded further and process, after service equipment has processed message and has forwarded the packet back the switch connecting this service equipment each time, the resource pool of the metadata in message can be indexed and be updated by switch, and resource pool index upgrade provides the resource pool index in the Service Source pond of service for the next one。For step 4104, the resource pool index in the SC Service Source pond belonging to SS1 is 1, in business chain, Service Source pond index after SC Service Source pond is 2, SS1 to switch 1 transmission process after message after, the resource pool of the metadata of this message is indexed 1 and is updated to 2, in order to message accepts the service of the service equipment in next Service Source pond。

Step 4106, the first switch are according to forwarding configuration by the message transmission after process to next switch or destination host。

Before message flows through business chain, the forwarding configuration that the first switch first receiving management node sends, therefore when message flows through business chain, the first switch can according to forwarding configuration to be sent by the message after process to next switch or destination host。The service equipment that this forwarding configuration includes the metadata corresponding with the first switch, the first switch connects provides the port that the service equipment of service is corresponding。For step 4105, due to switch 1 receive that management node sends forward configuration to include the metadata corresponding with switch 1, switch 1 connects port corresponding to SS1: No. 2 ports, and switch 1 receive the message after SS1 processes after the resource pool of metadata indexed 1 be updated to 2, therefore, switch 1 sends to switch 2 according to the message after forwarding configuration to be processed by SS1。If switch 3 receives the message after service equipment processes, then switch 3 sends to destination host according to the message after forwarding configuration to be processed by service equipment。

It should be noted that, the technical staff in described field is it can be understood that arrive, for the convenience described and brief introduction, the method for foregoing description is referred to aforementioned when the corresponding process in the business chain processing method embodiment that the network equipment is during management node, does not repeat them here。
