It surveys, therefore can also include being used to indicate the state that link is not detected in transmission quality state.Illustratively, each of the links
Transmission quality state can be divided into three kinds of states: first state is used to indicate link and is not detected；Second state, for referring to
Show that the transmission quality of link meets preset requirement；The third state, the transmission quality for being used to indicate link do not meet preset requirement.
In a kind of possible embodiment, the transmission quality state of each of the links can be indicated by marker, be passed through
It is different numerical value by the home position, can indicates different transmission quality states.Illustratively, if the home position is 1,
It can illustrate that the transmission quality of the link meets preset requirement, if the home position is 0, it may be said that the transmission quality of the bright link
Preset requirement is not met, if the home position is 2, it may be said that the bright link is not detected also, needs to carry out detection process.When
So, in practical application, different transmission quality states can also be configured according to different needs, does not limit three of the above,
And the specific value of above-mentioned marker can configure according to actual needs, and above-mentioned numerical value is only used as exemplary illustration, not
Play restriction effect.
For connecting the information of the second outgoing interface of each of the links on (3) second forwarding devices.
Since the different outgoing interfaces of each forwarding device can with Internet protocol (Internet Protocol, IP)
Location and port numbers can wrap come the information for the second outgoing interface for identifying, therefore being used to connect each of the links on above-mentioned second forwarding device
Include the IP address and port numbers of the second outgoing interface.For example, it is assumed that the second forwarding device passes through the second outgoing interface #21 and first turn
The first object outgoing interface #11 for sending out equipment is connected, and constitutes link #1, and the IP address of the second outgoing interface #21 is 100.1.1.1, end
Slogan is 60000, then the information of the second outgoing interface #21 of the second forwarding device connecting link #1, as IP address
100.1.1.1 port numbers 60000.
In some embodiments of the present application, each of the links are detected for the ease of the first forwarding device of instruction, it is above-mentioned
It further include default detection parameters, such as packet loss threshold value, propagation delay time threshold value etc. in field, for detecting the transmission of each of the links

That is the evaluation criterion whether transmission quality for evaluating each of the links meets preset requirement might not be identical, pass through differentiation
The transmission quality of different links can determine transmission quality more preferably link, higher to transmission quality requirements for forwarding
Service traffics.
In addition, above-mentioned predicted detection parameter can also be pre-configured in the first forwarding device and the second forwarding device, in this way,
If do not carry above-mentioned predicted detection parameter in the first flowspec message, it is also based on local be pre-configured with
Predicted detection parameter, to judge whether the transmission quality of each of the links meets preset requirement.
Step 102, the first forwarding device are based on the first flowspec message after receiving the first flowspec message
The transmission quality state of each of the links in at least both links of middle carrying determines transmission quality state symbol at least both links
Close the second target outgoing interface that linking objective link is used on the Target Link and the second forwarding device of preset requirement.
In specific implementation, if the first forwarding device recognizes at least both links, there are transmission quality states to be set to
The link to be detected of one state, that is, existing without the link by detection, then the first forwarding device also can star detection
Process detects every link to be detected.
Illustratively, for every link to be detected, the first forwarding device can be second turn of chain road direction to be detected by this
It sends out equipment and sends probe messages, and receive the response message that the second forwarding device is replied by the link to be detected.Pass through this
Process is detected, the first forwarding device can detect the transmission matter such as propagation delay time, the packet loss of probe messages in transmission process
Measure parameter.
It is possible to further by the transport quality parameters detected default detection parameters corresponding with the link to be detected into
Row comparison, determines detection result, for example, it is assumed that transport quality parameters include propagation delay time, packet loss, default detection parameters include
Propagation delay time threshold value, packet loss threshold value, then by comparison propagation delay time and propagation delay time threshold value, if propagation delay time is lower than transmission
Delay threshold and packet loss are lower than packet loss threshold value, then can determine and detect successfully, fail otherwise, it determines detecting.
Further, if detection result is to detect successfully, the transmission quality state of the link to be detected can be set to
Second state；If detection result is detection failure, the transmission quality state of the link to be detected can be set to the third state.
After the completion of detection, the first forwarding device can be determined extremely based on the transmission quality state of each link after detection
Transmission quality state meets the Target Link and the second forwarding device linking objective link of preset requirement in few both links
Second target outgoing interface.In a kind of possible embodiment, the first forwarding device can pass through the transmission matter of identification each of the links
Amount state selects transmission quality state to be set to the link of the second state, as Target Link from least both links.
It wherein, can be by an above-mentioned transmission quality if the link that transmission quality state is set to the second state is one
State is set to the link of the second state as Target Link；If the link that transmission quality state is set to the second state is at least two
Item is then set to selection target link in the link of the second state from least two transmission quality states based on preset strategy.Wherein,
Predicting strategy can be to randomly select a link to be used as Target Link as Target Link, or by each of the links, with reality
Existing load balancing.
Step 103, the first forwarding device are searched the first forwarding in local routing table and are set after receiving service traffics
The standby upper first object outgoing interface for forwarding service flow.
Wherein, the contents in table recorded in local routing table include but is not limited to destination address, outgoing interface information and under
One jumps out the corresponding relationship between interface message.
In specific implementation, since the first outgoing interface of the first forwarding device has multiple, the corresponding chain of each first outgoing interface
Road might not correspond to the link connected between the second forwarding device, also not necessarily correspond between the second forwarding device
The Target Link of connection, therefore the first forwarding device can be by searching the destination addresses pair of the service traffics in local routing table
The information for the first outgoing interface answered, to determine the first object outgoing interface for being used for forwarding service flow on the first forwarding device.
If step 104, first object outgoing interface connect the second target outgoing interface, the first forwarding device by Target Link
Pass through Target Link forwarding service flow.
In specific implementation, if first object outgoing interface connects the second target outgoing interface by Target Link, it can be said that
The bright service traffics match with Target Link, i.e., service traffics are transferred by the first object outgoing interface of the first forwarding device
After going, Target Link can be passed through, the second target outgoing interface of the second forwarding device is reached, received by the second forwarding device.
In above-mentioned process, during forwarding service flow, it is understood that there may be some and unmatched industry of Target Link
Be engaged in flow, i.e., can not selection target link forwarding service flow the case where, common routing rule can be based in this case
It is forwarded service traffics.
Illustratively, if meet following any condition, the first forwarding device can be based on remembering in local routing table
The route table items forwarding service flow of record.Wherein, any condition are as follows:
Condition 1, at least there is no the links that transmission quality state is set to the second state in both links；
Condition 2, first object outgoing interface do not connect the second target outgoing interface by Target Link；
Condition 3, the information for not finding the second target outgoing interface in local routing table.
In the embodiment of the present application, increasing the field by way of being used to indicate link selection newly in flowspec message, the
Parameter defined in new field in the flowspec message that one forwarding device can be sent based on the second forwarding device, comes true
The transmission quality state of the fixed each of the links between the second forwarding device, and selected based on the transmission quality state of each of the links
Transmission quality meets the Target Link of preset requirement, and further, the first forwarding device may be used also after receiving service traffics
Whether the second forwarding device is connected by Target Link with the first object outgoing interface by judgement for forwarding service flow
Second target outgoing interface, to determine whether service traffics match with Target Link, for the business to match with Target Link
Flow can be forwarded by the Target Link, to improve the transmission quality of service traffics.
In addition, executing the step 102, i.e. the first forwarding device is completed to treat detecting link in the embodiment of the present application
Detection after, the transmission matter of respective links in the new field of the first flowspec message can be updated based on detection result
Amount state, and step 105 can also be performed, it should be noted that above-mentioned steps 105 and above-mentioned steps 103 to step 104

Using router#A as above-mentioned second forwarding device, using router#C as above-mentioned first forwarding device, it is assumed that
The IP address of the outgoing interface #A1 and outgoing interface #A2 of router#A are respectively that 100.1.1.1 and 200.1.1.1, port numbers are respectively
The IP address of the outgoing interface #C1 and outgoing interface #C2 of 60000 and 60001, router#C be respectively 101.1.1.1 and
201.1.1.1, port numbers are respectively 60000 and 60001.In addition, it is assumed that the outgoing interface being connect on router#G with router#A
IP address be 1.1.1.1, the IP address of the upper outgoing interface connecting with router#C of router#E is 2.2.2.2.
So, the interaction flow between router#A and router#C, includes the following steps:
Firstly, router#A sends the first flowspec message as BGP flowspec controller, to router#C.
Wherein, it is increased newly in the first flowspec message and is used to indicate the field that link chooses mode.
Illustratively, above-mentioned new field can use Tag-Length-Value (tag-length-value, TLV) structure,
Specific format is for example are as follows:
<type,length,(length,rir-flag),(length,rir-addr),(length,rir-port),
(length,rir-pa ra)>。
Wherein, the selection of type field identification link acts, and can fill out 0x800a；Rir-flag field is used to identify link
Transmission quality state sets 1 mark link transmission quality and meets preset requirement, sets 0 mark link transmission quality and does not meet default want
It asks, sets 2 mark links and do not detected；Rir-addr field is used to the specific address path of label detection link-quality, i.e., the
Second outgoing interface IP address of two forwarding devices；Rir-port field is used to the listening port of label detection link-quality, i.e., the
The port numbers of second outgoing interface of two forwarding devices；Rir-para field is used to indicate the requirement ginseng of label detection link-quality
Number, as above-mentioned default detection parameters, wherein rir-para field both can have or not have.Length identifies every type
The length that the field of type occupies.
Illustratively, for for the link #1 and link #2 between router#A and router#C, the first flowspec
New field is respectively as follows: in message
Apply<Type0x800a,(rir-flag2),(rir-addr100.1.1.1),(rir-port 60000)>；
Apply<Type0x800a,(rir-flag2),(rir-addr200.1.1.1),(rir-port 60001)>。
Wherein, the transmission quality state of link #1 and link #2 is set to 2, illustrates that link #1 and link #2 are not visited also
It surveys.
In addition, can also include Flow_spec_nlri (1.1.1.1,2.2.2.2) field in the first flowspec message,
The field is original field in the first flowspec message, can be used for matching the feature of service traffics, for specific business
Flow is acted using respective links selection.For example the service traffics that specified destination address is 1.1.1.1 and 2.2.2.2 execute chain
Road selection movement.
Then, router#A can call Network Quality Analysis after sending the first flowspec message automatically
(Network Quality Analyzer, nqa) module, monitoring destination address by port numbers 60000 is 100.1.1.1
Nqa probe messages；The nqa probe messages that destination address is 200.1.1.1 are monitored by port numbers 60001.
Further, router#C recognizes link #1's and link #2 after receiving the first flowspec message
Transmission quality state is set to 2, can call nqa module, passes through port numbers 60000 respectively to destination address 100.1.1.1, port
Numbers 60001 initiate nqa detection to destination address 200.1.1.1.It, can be by chain if link #1 and link #2 detect success
The transmission quality state of road #1 and link #2 is set to 1, conversely, if link #1 and link #2 detect failure, it can be by link #
The transmission quality state of 1 and link #2 is set to 0.
Wherein, the embodiment of specific detection process is referred to detection process described in Fig. 1, here not reinflated theory
It is bright.
Further, after router#C has executed detection process, the 2nd flowspec message can be sent to router#A.
Wherein, the content carried in the 2nd flowspec message includes:
Apply<Type0x800a,(rir-flag1,(rir-addr100.1.1.1),(rir-port 60000)>；
Apply<Type0x800a,(rir-flag1),(rir-addr200.1.1.1),(rir-port 60001)>。
It also, also include original field, here not reinflated explanation in the 2nd flowspec message.
Further, router#A has determined the transmission quality state for the both links being connected with router#C,
Router#A and router#C are after receiving service traffics, the flow forwarding process that executes respectively are as follows:
For router#C:
Router#C determines that the transmission quality state for the both links being connected with router#A sets 1, i.e. link #1 and chain
Road #2 is Target Link, and the second target outgoing interface that router#A is separately connected link #1 and link #2 is respectively outgoing interface #A1
With outgoing interface #A2, corresponding information is respectively 100.1.1.1,60000,200.1.1.1,60001.
Router#C can identify the destination address of service traffics after receiving service traffics, if the mesh of service traffics
Address be not in flowspec message specify destination address 1.1.1.1 or 2.2.2.2, then the service traffics directly pass through
Common routing rule is forwarded.
If the destination address of service traffics is the destination address specified in flowspec message, then can be further at this
The corresponding first outgoing interface information of destination address of service traffics is searched in ground routing table, so as to router#C determine from which the
One target outgoing interface forwards the service traffics.
In one example, if the destination address of the service traffics received is 1.1.1.1, by searching for local routing table, really
The fixed destination address corresponds to the outgoing interface #C1 that IP address the is 101.1.1.1 and outgoing interface # that IP address is 201.1.1.1
C2, because outgoing interface #C1 is said by link #1 connection outgoing interface #A1, outgoing interface #C2 by link #2 connection outgoing interface #A2
The bright service traffics are matched with link #1 and link #2, can be forwarded by least one link in link #1 and link #2
The service traffics.
In another example, if the destination address of the service traffics received is 2.2.2.2, by searching for local routing table,
Determine that the corresponding outgoing interface of the destination address is not the outgoing interface #C1 that IP address is 101.1.1.1 and IP address is
201.1.1.1 outgoing interface #C2, then the corresponding outgoing interface of destination address cannot be by link #1 connection outgoing interface #A1, also not
It can illustrate that the service traffics and link #1 and link #2 are mismatched by link #2 connection outgoing interface #A2, it can be by common
Routing rule is forwarded.
For router#A:
Router#A determines that outgoing link #1 and link #2 is Target Link, and router#A is separately connected link #1 and link #2
The second target outgoing interface be outgoing interface #A1 and outgoing interface #A2, corresponding information is respectively 100.1.1.1,60000,
200.1.1.1、60001。
Router#A can identify the destination address of service traffics after receiving service traffics, if the mesh of service traffics
Address be not in flowspec message specify destination address 1.1.1.1 or 2.2.2.2, then the service traffics directly pass through
Common routing rule is forwarded.
If the destination address of service traffics is designated destination location, then can further search in local routing table
The corresponding second outgoing interface information of the destination address of service traffics is somebody's turn to do so which the second outgoing interface forwarding router#A determines from
Service traffics.
In one example, if the destination address of the service traffics received is 2.2.2.2, by searching for local routing table, really
The fixed destination address corresponds to the outgoing interface #A1 that IP address the is 100.1.1.1 and outgoing interface # that IP address is 200.1.1.1
A2, because outgoing interface #A1 belongs to direct-connected interface, i.e. outgoing interface #A1 is direct-connected with itself by link #1, and outgoing interface #A2 is also belonged to
Direct-connected interface, i.e. outgoing interface #A2 are direct-connected with itself by link #2, and the service traffics are also considered as and Target Link in this case
Matching, can use at least one link in link #1 and link #2 also to forward the service traffics.
In another example, if the destination address of the service traffics received is 1.1.1.1, by searching for local routing table,
Determine that the corresponding outgoing interface of the destination address is not the outgoing interface #A1 that IP address is 100.1.1.1 and IP address is
200.1.1.1 outgoing interface #A2 illustrates that the service traffics and Target Link mismatch, can pass through common road in this case
It is forwarded by rule.
So far, router#A and router#C can be acted by link selection, to select the higher target of transmission quality
Link, and then the service traffics to match with Target Link can be forwarded by Target Link, so as to improve Business Stream
The transmission quality of amount.
