Deng.The differentiation that flow does not have differentiation must cause unnecessary burden to these equipment once by these business devices,
The optimization of Service Source is limited, configuration is complicated, is difficult to realize the quick change of service configuration.
In view of the above-mentioned problems, it is currently suggested a kind of mode service function chain (the Service Function of business chain
Chain, referred to as SFC), i.e., all service business are integrated, fictionalize Service overlay layers, form the clothes of oneself
Business topology, and bottom-layer network are decoupling, are no longer influenced by the limitation of bottom-layer network structure, framework is as shown in Figure 1.Flow to be passed through
Business determined by SFC.SFC is by increasing service function ID of trace route path (the Service Function Path to every SFC
Identifier, referred to as SFPID), and message is classified, the different SFC of the assignment of traffic to different stage is (by entrance
Classifying equipoment is done).Forwarding unit then forwards to message according to SFC mark.So as to realize for different flows,
Different business chain processing can be implemented, realize differentiated demand.
As shown in figure 1, SF is business function, SFF is business function transponder for the processing of current operation functional chain, according to report
The SFPID carried in text selects different SF or SFF to forward message, i.e., the message received from grader or SFF,
SFF can be forwarded to the SF for belonging to this business chain path according to the SFPID of message；The message received from SF, SFF can be according to messages
SFPID select next-hop, then message is sent on next SFF according to the address of next-hop.
For for wide area network and across some scenes of data center, industry proposes a kind of stratification SFC at present, i.e., wide
The online SFC in domain is referred to as upper strata SFC, and the SFC inside data center of process is referred to as lower floor SFC.As shown in Fig. 2 work as

One business function chain ID of trace route path SFPID1 of assignment of traffic, the SFPID1 is added to the head of message, the industry on wide area network
Business functional entity can be handled and forwarded to message according to this SFPID1.
When message will be handled using the business function in DC networks, message can be sent to the gateway for renting network first
Place, gateway then may proceed to be sent in the grader of this DC networks further makes classification to the message.Here grader can be with
With gateway separation or physics one.Grader needs to combine what message had carried when classifying to message
The SFPID1 of wide area network carries out the classification in DC networks together, while generates the business function in the DC networks according to classification results
Chain ID of trace route path SFPID2, and the SFPID2 is added to the head of message again, the SFPID1 before message is encapsulated in
Inside SFPID2 heads, as shown in Figure 3.
Message can be handled and forwarded according to this SFPID2 for the business function entity in DC networks, it is right
SFPID1 is not perceived and handled.
When message, which will leave this, rents network, the forwarding unit SFF that the business function of message is connected finally is handled
The gateway of present networks is relayed to after can this SPFID2 encapsulation be peeled off, wide area network or next DC nets are then sent through by gateway
Business function between the domain of network, follow-up processing is done to message by the business function.

Information.
Above-mentioned data handling procedure is illustrated below in conjunction with an example, but is not used in the skill for limiting the embodiment of the present invention
Art scheme.
In fact, because some metadata for helping SF to handle data are carried on each SFC heads
(metadata) what, in general, metadata mainly carried is some control information related to this message, such as station address
Information, Qos strategies, facility information, user's mark etc., these metadata just add when message encapsulates upper strata SFC heads to be applied to
In SFC heads, but message, after data center network inside is entered, the SF that these metadata are also required to inside data center can
See processing, while after lower floor SFC SF carryings have handled some metadata, it is also desirable to the SFC of last time can be passed to, therefore

The example below is crossed to be explained：
Clasfficiator (Classifier)：When on upper strata, SFC flow enters lower floor SFC, lower floor SFC clasfficiator will be given
Flow does the encapsulation of one layer of NSH head, while when this clasfficiator detects that message has been a SFC flow, then can again according to
Message is classified according to the head of the message, distributes a new NSH head (outer layer NSH) to message, this outer layer NSH is used
In mark lower floor SFC, while the part on clasfficiator internal layer NSH heads according to corresponding to this SFC needs by original upper strata SFC
Or whole metadata values are copied in the Metadata fields on outer layer NSH heads corresponding to lower floor SFC；When on lower floor SFC
SF needs to change metadata or adds metadata, then internal layer NSH need not be perceived, directly in outer layer NSH
Change or add in metadata.
In final jump SFF, when message will leave lower floor SFC, the SFF of lower floor SFC final jump needs to feel
Know after being two layers of NSH head, then the metadta in the NSH that will copy to outer layer before is returned in the NSH of internal layer, is then shelled again
From the NSH heads of outer layer；Otherwise, the NSH of the direct peeling outer layers of the SFF of final jump.

Preferred embodiment one：
As shown in fig. 7, source device S transmitted traffics are to purpose equipment D, the flow need by business function entity SF1,
SF2、SF3、SF4.Here each business function can be SF between a domain.Here SF is one in DC networks between domain
SFC, for wide area network, SF between a domain can be abstracted as.DC networks are supplied to only abstracting for upper strata wide area network
SF, what kind of path the SFC that upper layer network is not relevant for DC network internals is.
When upper layer network needs some specific business functions, some business functions can be rented into DC networks, such as
DPI, calculating etc., now that DC is supplied to wide area network control surface is the SF2 that a DPI adds calculating, for wide area network, this
Individual SF2 also has business function between corresponding this domain of SF2 of SFID2 marks as other SF1.
For the control plane of wide area network, that DC networks need to provide is exactly this SFID2, and gateway address work
For wide area network SFC next-hop.The chain of command of wide area network needs to inform the business work(which SFC of DC networks will be rented in DC
Can, i.e. the SFPID1 of wide area network.DC network internals need to determine the SPFID1 and SFC (SPFID2) in present networks correspondence.Need
The SFC to be reselected according to information such as the SPFID1 for entering DC networks and 5 yuan of ancestrals of message inside DC is (corresponding
SPFID2)。
In a preferred embodiment of the invention, the message that S is sent carries out classification processing in the Classifier of wide area network, and
SFC head part S FPID1 is encapsulated to the message according to classification results, while is carried required when handling this message
Some metadata Metadata1, as shown in Figure 8.Such as user profile (user information) is carried in metadata1
With Qos strategies on this SFC, each SFF is forwarded according to SFPID1.When message is forwarded to the gateway of DC nets, gateway
Message is sent to the Classifier of DC nets according to strategy, by the Classifier of DC nets to the classification in message progress network.
Classifier receives the message with NSH heads, can according to strategy, such as the SPFID1 on the SFC heads and/or message its
His header information obtains the sub-SFC ID of trace route path SPFID2 in this DC networks, has carried needs in DC to message classification
The metadata metadata2 used.Increase the SFC heads of DC networks oneself, referred to as outer layer on the basis of original SFC heads
NSH, originally SFC heads are referred to as internal layer NSH.Here outer layer NSH not only includes for the forwarding of DC interior business functional chain
SFPID2, and in order to ensure the SF inside data center network entrained by the Metadata1 on original upper strata SFC heads
It can use, therefore the part or all of metadata in the metadata1 on former internal layer SFC heads is placed on internal layer by Classifier
In the metadata2 on SFC heads, and metadata2 is together placed in the metadata fields on outer layer SFC heads.The present embodiment
Metadata1 user profile and Qos policy informations have all been copied in outer layer NSH metadata2 in middle internal layer NSH.This
When internal layer SFC heads in metadata1 can retain, can not also retain, as shown in figure 9, so as to ensure in data center
The SF in portion, directly message is handled accordingly without parsing outer layer SFC heads can.
In data center network, it is assumed that SF21 is a DPI, then may be according to the analysis to message, by the message
The content such as attribute add in outer layer NSH metadata2, SF22 is a load balancing equipment, may be changed
Qos policy informations in metadata2.Without perceiving internal layer NSH, and internal layer NSH metadata1 is dealt with.
When flow is reached on the SFC of DC networks final jump SFF, last SFF needs the NSH heads of peeling outer layer,
At this moment need using the NSH heads of the metadata2 on outer layer NSH heads content recovery to internal layer as metadata1, so as to protect
The metadata of processing addition modification can continue to carry with the forwarding of message in card data center, for other networks below
SF can continue to handle.
In summary, the embodiment of the present invention has reached following technique effect：Solve in correlation technique, the true nothing of prior art
Method realizes the problem of SF can identify two layers of SFC head and then cause the data on two layers of SFC head not to be resolved to simultaneously, protects
Having demonstrate,proved SF can be to the dissection process on both sides SFC heads.
