Embodiment
The method for releasing resource in business function chain in one embodiment, as shown in figure 1, this method bag
Include：
Step S110：Grader construction stream release message message when detecting that stream is in done state.
Grader (Classifier) is a node in business function chain (SFC), and SFC node also wraps
Include business function transponder (SFF), business function (SF) and business function agency (SFC Proxy).
In one SFC system, the quantity of grader, SFF and SF can be one or more, SFC Proxy's
Quantity can be zero, one or more.SFC encapsulation is carried out to message, so that the message after encapsulation can be with
Forwarded independent of destination address, the flexible transmission message between SFC node.Grader is responsible for knowledge
And stream and SFC Liu not be associated, corresponding SFC will be streamed to and handled up.
Stream release message (Flow Release, FR) message carries stream release mark (Flow Release
Indicator, FRI) and stream link information.FR messages are to carry the related letter of stream using SFC encapsulation
The message of breath, forwarded along SFC paths.FRI is the mark of instruction stream release information, for follow-up
Identify FR messages.Link information is used to indicate processing path of the stream in SFC, and SFC is according to link information pair
Stream is forwarded.In the present embodiment, link information may include service path mark (Service Path Identifier,
) and service identification (Service Index, SI) SPI.Link information is carried in FR messages, to send
To node follow-up on SFC corresponding to stream.The initial message (Original Packet) of FR messages partly may be used
Use corresponding IP five-tuples (source address, source port number, protocol number, destination address, destination interface in stream
Number) one message of construction.The payload part of initial message does not require, carries the FR of IP five-tuples
Message may indicate that corresponding stream.
When detecting that stream is in done state, then need to discharge the resource in SFC shared by the stream, grader
The link information of corresponding stream is obtained, and SFC encapsulation is carried out according to link information, obtains carrying FRI and chain
The FR messages of road information.The concrete mode that detection of classifier stream is in done state is not unique, can be straight
Connect convection current and carry out state-detection or can be by DPI (Deep Packet Inspection, deep packet
Detection technique) detect the knot that TCP (Transmission Control Protocol, transmission control protocol) is connected
Shu Xinling perceives the end of stream.When detection of classifier is to the resource for needing some stream of release SFC, structure
Make FR messages and issue node follow-up on SFC corresponding to the stream.
It is also not unique that FRI concrete mode is carried in FR messages, can carry the base in FR messages
In this head or carry in the context head of FR messages.
Step S120：Grader is sent to corresponding business function according to link information by release message message is flowed
Transponder.
Grader directly can be believed after encapsulation obtains carrying FRI and link information FR messages according to link
Breath sends FR messages to node follow-up on corresponding SFC, i.e., corresponding SFF.
Step S130：Business function transponder will be flowed corresponding to release message message is forwarded to according to link information
Functional node.
SFF is responsible for the message to encapsulation, and the information included according to message is forwarded.SFF receives FR reports
Wen Hou, FR messages are forwarded to corresponding functional node according to the link information of carrying.The quantity of functional node
Can be one or more.When the quantity of functional node is multiple, SFF can be straight according to link information
Connect FR messages while be sent to all corresponding functional nodes, so that functional node carries out resource release behaviour
Make.SFF can also be FR messages are forwarded to by next-hop SFC nodes according to link information corresponding to function
Node., can be with if FR messages are sequentially forwarded to each functional node by SFF according to link information
It is to send FR messages to a functional node, and after the FR messages of functional node return are received, continues
FR messages are sent to next functional node；Can also send FR messages to a functional node preset duration
Afterwards, it is unlimited to next functional node, concrete form to continue transmission FR messages.
Step S140：Functional node is after stream release message message is received, according in stream release message message
Resource corresponding to the stream release mark release of carrying.
Functional node is after FR messages are received, the resource according to corresponding to discharging the FRI carried in FR messages,
Avoiding the occurrence of thus can not discharging resource in time causes service quality to decline problem.
Method for releasing resource in above-mentioned business function chain, after detecting that stream is in done state, grader
Construction carries the stream release message message of the link information of stream release mark and stream, and is forwarded through business function
Device is sent to functional node.Functional node is after stream release message message is received, according to stream release message report
Resource corresponding to the stream release mark release carried in text.By monitoring the state of stream, and in stream in end
Constructed during state and send stream release message message so that resource corresponding to the timely release of functional node, can
Stream is perceived in time to terminate and carry out resource release operations, is avoided appearance and is taken caused by it can not discharge resource in time
The problem of business Quality Down, improve QoS.
In one embodiment, reservation bit of the stream release mark positioned at the basic head of stream release message message
Position.
The type of SFC encapsulation can have a variety of, including NSH (Network Service header network services
Header) type, the encapsulation format of same encapsulated type such as encapsulation also have a variety of available.Encapsulated with NSH
Exemplified by, FRI can choose a reservation bit position on NSH basic head as FRI, be defined as F ratios
Spy, as shown in Fig. 2 F bits are the message that 1 mark is release stream.By choosing the basic of FR messages
The reservation bit position on head is easy to operate and easy to identify as FRI.
In one embodiment, stream release message message carries stream release mark, including：If business function
Chain encapsulation format is f format, then the bit for choosing the essential context head of stream release message message is made
For stream release mark；It is raw in release message message is flowed if business function chain encapsulation format is elongated form
Into elongated context head as stream release mark.
Equally so that NSH is encapsulated as an example, reference picture 3 and Fig. 4, if NSH encapsulation format is f format,
MD type characterize NSH encapsulation format, and the encapsulation format that MD type are 1 expression NSH is f format,
The encapsulation format that MD type are 2 expression NSH is elongated form.
If MD type are 1, a NSH bit on essential context head is chosen as FRI, it is fixed
Justice is F bits, as shown in figure 3, F bits are the message that 1 mark is release stream.If MD type are 2,
A new elongated context head is defined as FRI, as shown in figure 4, it is release stream that FRI, which is 1 mark,
Message.TLV Class, the type field can determine that C bits are arranged to 1 as the case may be.
It is to provide two kinds of different FRI set-up modes according to SFC encapsulation format is corresponding above, can be according to reality
Border situation is correspondingly arranged FRI.
In one embodiment, functional node includes the business function of the encapsulated type of recognizable business function chain.
SF quantity can be it is one or more, SF can Direct Recognition SFC encapsulated type.Sealed with NSH
Exemplified by dress, SF supports the message of the stream of NSH encapsulation, can directly invoke respective resources convection current and be handled, and
Preserve contextual information.After FR messages are issued SF by SFF, SF equally can Direct Recognition FR messages,
And resource corresponding to discharging, the stream for avoiding terminating hold over resource.
Specifically, SF is also detected certainly after resource corresponding to the FR messages of SFF forwardings and release is received
Whether body is located at the final jump on SFC, if so, then resource release is completed, SF can not return to FR messages
To SFF；If it is not, then SF returns to FR messages to SFF, so that SFF sends FR messages to next SF.
It is appreciated that in other embodiments, SFF can also be by FR messages while send to all SF.
In one embodiment, functional node is acted on behalf of including business function.
SFC Proxy quantity can be one or more, and SFC Proxy are used as and do not support SFC encapsulated types
SF agency, in requisition for the message for giving SF, SFC Proxy message is taken off send after encapsulation to
SF；To the message received from SF, SFC Proxy are responsible for being packaged, then issue other nodes.SFC Proxy
As the SF for the encapsulated type that can not identify SFC agency, needed also exist for when convection current is handled in preservation
Context information.After FR messages are issued SFC Proxy by SFF, SFC Proxy Direct Recognition FR messages,
And resource corresponding to discharging, the stream for avoiding terminating hold over resource.
Specifically, SFC Proxy are after resource corresponding to the FR messages of SFF forwardings and release is received, also
The final jump whether itself is located on SFC is detected, if so, then resource release is completed, SFC Proxy can
FR messages are not returned to SFF；If it is not, then SFC Proxy return to FR messages to SFF, so that SFF will
FR messages are sent to next SFC Proxy.It is appreciated that in other embodiments, SFF can also be by
FR messages are sent to all SFC Proxy simultaneously.
Further, in one embodiment, functional node includes business function agency and can recognize that business work(
The business function of the encapsulated type of energy chain.
SF and SFC Proxy quantity can also be one or more, SF and SFC Proxy can received
After to the FR messages for carrying FRI, according to resource corresponding to the release of FR messages.SF and SFC Proxy can be with
It is to carry out resource release simultaneously, is not also while carries out resource release, and sequencing is not unique, tool
Body forwards the mode of FR messages to determine by SFF according to link information.If FR messages are transmitted to by SFF simultaneously
SF and SFC Proxy, then carry out resource release simultaneously；If FR messages are first forwarded to one of them by SFF
Functional node, the then functional node for receiving FR messages first carry out resource release.In SFF by FR messages
After being forwarded to another functional node, another functional node carries out resource release again.
FR messages are first forwarded to by SF with SFF, then are forwarded to exemplified by SFC Proxy.SFF reports by FR
After text is forwarded to SF, SF release corresponding to resource, and detect itself be not located at it is last on SFC
During one jump, FR messages are returned to SFF.FR messages are forwarded to SFC Proxy by SFF, and SFC Proxy are same
Resource corresponding to sample release, and detect whether itself is final jump on SFC, if so, then resource discharges
Complete, SFC Proxy do not return to FR messages to SFF；If it is not, then SFC Proxy return to FR messages extremely
SFF, so that SFF forwards FR messages again.
It is appreciated that in other embodiments, SFF can also be that FR messages first are forwarded into SFC Proxy,
SF is forwarded to again after the FR messages of SFC Proxy returns are received.
Be above for functional node multi-form provide corresponding to resource delivery mode, can be according to work(
Can the different structure of node correspondingly carry out resource adjustment, improve the convenience of resource release operations and comprehensive.
It is appreciated that more than the concrete form of functional node and corresponding resource delivery mode include but is not limited to
Embodiment.
In one embodiment, as shown in figure 5, after step S140, the above method may also include：
Step S150：Functional node according to stream release message message in link information, judge itself whether be
Final jump on business function chain.
Because the link information in FR messages may indicate that path of the corresponding stream in SFC, functional node according to
Link information can determine whether itself is final jump on SFC, if so, then the corresponding stream of explanation is SFC's
Processing path terminates, can not returned packet to SFF；If it is not, then carry out step S160.
Step S160：Functional node is back to business function transponder by release message message is flowed.
Functional node returns to FR messages, specifically can change the link in FR messages according to the Message processing of stream
SFF is back to after information.Functional node detect be not located at final jump on SFC when, FR is reported
Text is back to SFF, and resource release operations are carried out so that FR messages are forwarded to next functional node by SFF.
Step S170：Business function transponder receives the stream release message message returned, will according to link information
Stream release message message is sent to next functional node.
It is appreciated that next functional node is after resource corresponding to release, if it itself is not SFC still to detect
On final jump, then continue to return FR messages to SFF, until the function section positioned at SFC final jumps
Put also resource corresponding to release.
In addition, in step S150, if functional node is located at final jump on SFC, FR equally also can return to
Message is to SFF.Because resource release is over, SFF will not carry out message forwarding again.
In the present embodiment, functional node also returns to FR when it is not the final jump on SFC to detect itself
Message, so as to account for resource corresponding to the equally release of next functional node, is released successively to SFF according to link information
Corresponding resource in each functional node is put, avoids the occurrence of omission, improves SFC resources release reliability and comprehensively
Property.
It is appreciated that in other embodiments, if the quantity of functional node only has one, or SFF is simultaneously
FR messages are sent to corresponding all functional nodes, then functional node is not required to after resource corresponding to release
Judge whether corresponding stream terminates in SFC processing path, be also not required to return to FR messages.
