Method, device, the network equipment and machine readable storage medium.In the following, being provided for the embodiments of the invention data traffic point first
Load method is introduced.
Data traffic sharing method provided by the embodiment of the present invention is applied to the above-mentioned network equipment as source node, should
The network equipment can have the network equipment of data forwarding function for router, interchanger etc..Realize that the embodiment of the present invention is mentioned
The mode of the data traffic sharing method of confession can be in the software, hardware circuit and logic circuit being set in the network equipment
It is at least one.
As shown in Fig. 2, a kind of data traffic sharing method provided by the embodiment of the present invention, may include steps of.
S201 when the current detection period reaches, sends a probe messages along every equative route for reaching destination node,
Wherein, each probe messages carry parameter collection mark and return to mark, and parameter collection mark is used to indicate collector node mark
Know and node-node transmission parameter, return mark are used to indicate the equative route that destination node passes through each probe messages by it
It returns.
There are a plurality of equative routes between source node and destination node, can construct a source address information on the source node
Address information, the probe messages that destination address information is purpose address of node information for source node respectively specify that detection report
The next-hop address information of text is sent for the address information to adjacent node on every equative route, then every equative route
On can all transmit a probe messages to destination node.Also, source node is on each equative route, is periodically to send
Probe messages, every detection cycle will send a probe messages.For example, having 3 between source node and destination node
Equative route, source node can send respectively a probe messages at interval of 1 second on 3 equative routes.
Probe messages carry parameter collection mark, and parameter collection mark is used to indicate collector node mark and node-node transmission
Parameter.Probe messages one node of every arrival, the node can identify the parameter collection mark of probe messages, then can be by itself
Node identification and the obtained node-node transmission parameter of detection be added in probe messages.Node-node transmission parameter refers to that node-node transmission is visited
When observing and predicting text, with the parameter information that can characterize transmission performance, such as exit port bandwidth availability ratio, timestamp etc..
Probe messages also carry return mark, once destination node receives probe messages, identify return mark, just
Know that the probe messages received are returned to source node by needs.It is according to former road that destination node, which returns to probe messages to source node,
It returns, it is, such as destination node is to receive probe messages from equative route A-B-E, then can be incited somebody to action by equative route A-B-E
The probe messages return to source node.
In an implementation of the embodiment of the present invention, the return mark that probe messages carry can be loopback
(loopback) flag bit, the flag bit is in the heading of probe messages, and destination node is after receiving probe messages, according to heading
Loopback flag bit is interchangeable the destination address information and source address information of message, the probe messages received is returned
Back to source node.
In an implementation of the embodiment of the present invention, probe messages can be INT (Inband Network
Telemetry, band network telemetering) probe messages.Each probe messages are INT probe messages, and parameter collection is identified and returned
Mark is returned to be set in the INT head of INT message.Every to pass through a node, which can be according to INT parameter collection marks
Know, is inserted into the node identification and node-node transmission parameter of this node in the metadata metedata of band network telemetering message, INT is visited
After observing and predicting text arrival destination node, the metadata metedata after INT carries all node-node transmission parameters by node,
Node-node transmission parameter may include the information such as timestamp, exit port bandwidth availability ratio.Destination node receives INT probe messages
Afterwards, identify in INT return mark, then can by the INT probe messages according to backtracking to source node.
S202 judges whether every equative route is respectively received each return in scheduled duration in the current detection period
Probe messages.
Every arrival one-time detection period, source node will send a detection report to destination node along every equative route
Text, accordingly under normal circumstances, source node can be received in scheduled duration from every equivalence in each detection cycle
The probe messages that path returns, source node needs to judge such case, judges every road of equal value in the current detection period
Whether diameter is respectively received the probe messages of each return in scheduled duration.
Optionally, if the spy for thering is any equative route not receive return in scheduled duration in the current detection period
Text is observed and predicted, following steps can also be performed in data traffic sharing method provided by the embodiment of the present invention:
Judge not receive in scheduled duration within the current detection period probe messages of return equative route whether
The probe messages of return are not received in scheduled duration in the continuous N period, wherein M is the positive integer greater than 2；
If so, by the current detection period the affiliated equative route of the corresponding node of minimum node configured transmission it is next
It jumps, the replacement continuous N period does not receive multiple forwarding-table items of the equative route of the probe messages of return in scheduled duration
Next-hop in middle highest matching times forwarding-table item, so that the continuous N period does not receive the spy of return in scheduled duration
More than one the big flow Business Stream for observing and predicting the equative route of text is shared to belonging to the corresponding node of minimum node configured transmission
Equative route.
If source node illustrates this from the probe messages that a certain equative route is more than that scheduled duration does not receive return
Equative route the case where there may be time delay or packet losses, if repeatedly occurring is more than that scheduled duration is not received and returned from this paths
The probe messages returned then illustrate this equative route close to congestion or congestion.It then needs the one of this equative route
A above big flow Business Stream is shared to be transmitted on other equative routes, specifically share close to congestion or congestion etc.
The equative route of the data traffic of cost path is in the current detection period belonging to the corresponding node of minimum node configured transmission etc.
Cost path.Business Stream realizes that the mode shared is mainly that the next-hop address information passed through in replacement forwarding-table item is realized, for
How to be shared by the next-hop address information realization Business Stream in replacement forwarding-table item, detailed Jie will be in S204 step
It continues.
S203, if every equative route is respectively received the detection of each return in scheduled duration in the current detection period
Message identifies maximum node configured transmission then according to the corresponding node-node transmission parameter of node each in the probe messages of each return.
Within the current detection period, source node is receiving each detection report that destination node returns from every equative route
Wen Hou, can extract the corresponding node-node transmission parameter of each node from each probe messages, such as exit port bandwidth availability ratio,
Timestamp etc..Node-node transmission parameter is bigger, illustrates that the transmission performance of the node is poorer, therefore, can be from the corresponding section of each node
It identifies that maximum node configured transmission, maximum node configured transmission characterized in the current detection period in point configured transmission, transmits
The worst node of performance, corresponding equative route pack heaviest.
Optionally, node-node transmission parameter can be exit port bandwidth availability ratio.
Then S203 is specifically as follows:
According to the corresponding exit port bandwidth availability ratio of node each in the probe messages of each return, maximum exit port is identified
Bandwidth availability ratio.
The exit port bandwidth availability ratio of node refers to the ratio of the bandwidth utilized in the exit port of node, is that node passes
One important configured transmission of defeated Business Stream, the exit port bandwidth availability ratio of a node is bigger, then illustrates the outlet of the node
The bandwidth utilized on mouth is more.It is directed to the very big situation of exit port bandwidth availability ratio, if there is new Business Stream again
When coming up, if may also be more than the requirement of the node exit port maximum bandwidth, lead to Business Stream by this node-node transmission
Transmission failure.
Optionally, node-node transmission parameter can be timestamp.
Then it is specifically as follows in S203:
According to the corresponding timestamp of node each in the probe messages of each return, maximum node time delay is identified.
For source node, timestamp record is the time for sending probe messages；For destination node, the time
Stamp record is the time for receiving probe messages；For the node that centre is passed through, the reception that can be of timestamp record is visited
The time for observing and predicting text is also possible to send the time of probe messages.Node time delay refers to that the timestamp of a node and forwarding are visited
Observe and predict the difference of the timestamp of the upper hop node of this node on the equative route of text.For example, if source node sends detection
The timestamp of message is 9:40, and the timestamp that the next-hop node of source node receives probe messages is 9:45, then can calculate
The node time delay of the next-hop node of source node is 5 minutes out.
S204, when maximum node configured transmission exceeds preset threshold, by minimum node transmission ginseng in the current detection period
The next-hop of the corresponding affiliated equative route of node of number, the corresponding affiliated equative route of node of replacement maximum node configured transmission
Next-hop in multiple forwarding-table items in highest matching times forwarding-table item, so that the corresponding node institute of maximum node configured transmission
More than one the big flow Business Stream for belonging to equative route is shared to equivalence road belonging to the corresponding node of minimum node configured transmission
Diameter.
The node parameter of one node characterizes the load weight of the section link between this node and next-hop node,
For example, the exit port bandwidth availability ratio of a node is bigger, alternatively, the node time delay of a node is bigger, then show this section
The load of section link between point and next-hop node is heavier.Therefore, in embodiments of the present invention, it is provided with a default threshold
Value, which is to be configured according to the empirical data that data are transmitted, if maximum node configured transmission is beyond default
Threshold value then illustrates the overload of the section link between the corresponding node of maximum node configured transmission and next-hop node, into
One step, illustrate that the link load of the affiliated equative route of the node is too heavy, needs to carry out traffic sharing to it.
It is needed under normal conditions by more than one big stream of the affiliated equative route of the corresponding node of maximum node configured transmission
Amount Business Stream is shared to the affiliated equative route of the corresponding node of minimum node configured transmission.
In forwarding service stream, the data message triple of the Business Stream that source node is forwarded according to equative route, five-tuple,
Or seven tuple calculate hash (Hash) value, search the matched forwarding-table item of hash value of calculating, data message be sent to matched
Next-hop in forwarding-table item.When the flow of some Business Stream is bigger, it is matched to based on the hash value that the business stream packet calculates
The number of forwarding-table item then can be bigger.Therefore, it can be obtained according to the count value by the hardware counter for reading each forwarding-table item
The hit-count of each forwarding-table item is taken,.
Highest matching times turn in multiple forwarding-table items of the affiliated equative route of the corresponding node of maximum node configured transmission
The corresponding Business Stream of forwarding list item is exactly big flow Business Stream, pays the utmost attention to sharing these Business Streams into minimum node configured transmission
On the corresponding affiliated equative route of node.Specifically, being to be realized by the next-hop in modification forwarding-table item, by minimum node
The next-hop of the corresponding node equative route of configured transmission replaces the more of the corresponding node equative route of maximum node configured transmission
Next-hop in a forwarding-table item in highest matching times forwarding-table item, in this way, the big Business Stream of flow can pass through minimum node
The forwarding of equative route belonging to parameter.
Using the embodiment of the present invention, when reaching in the current detection period, source node is along every equivalence for reaching destination node
Path sends a probe messages, the corresponding node-node transmission parameter of each node, purpose section on the equative route for detect process
The received each probe messages of point carry the corresponding node of each node on its equative route passed through that detection obtains and pass
Defeated parameter, and each probe messages also carry parameter collection mark and return to mark, and destination node is identifying return mark
After knowledge, probe messages are returned into source node by its equative route passed through, source node judges in the current detection period every
Whether equative route is respectively received the probe messages of each return in scheduled duration, if received in scheduled duration every
The probe messages of a return, then according to the corresponding node-node transmission parameter of node each in the probe messages of each return, identification is maximum
Node-node transmission parameter, when maximum node configured transmission exceeds preset threshold, by minimum node transmission ginseng in the current detection period
The next-hop of the corresponding affiliated equative route of node of number, the corresponding affiliated equative route of node of replacement maximum node configured transmission
Next-hop in multiple forwarding-table items in highest matching times forwarding-table item, so that the corresponding node institute of maximum node configured transmission
More than one the big flow Business Stream for belonging to equative route is shared to equivalence road belonging to the corresponding node of minimum node configured transmission
Diameter.If maximum node configured transmission has exceeded preset threshold, illustrate belonging to the corresponding node of maximum node configured transmission etc.
The path load of cost path is heavier, and therefore, it is necessary to share to minimum node transmitting by the data traffic on this equative route joining
It is transmitted on the corresponding affiliated equative route of node of number.Detection by probe messages to node-node transmission parameter, detection obtain one
The corresponding node-node transmission parameter of each node, whole to measure based on the corresponding node-node transmission parameter of each node on equative route
The load weight of equative route illustrates maximum node configured transmission pair if maximum node configured transmission is greater than preset threshold
The path load of the affiliated equative route of the node answered is heavier, is born by sharing the data traffic on this equative route to path
It carries on lighter equative route (the affiliated equative route of the corresponding node of minimum node configured transmission), alleviates path load weight
The transmission burden of equative route, so that the data traffic for improving network shares effect.
In order to make it easy to understand, below with reference to specific example be provided for the embodiments of the invention data traffic sharing method into
Row is introduced.
As shown in figure 3, there are equative route 1:A-B-E-F, path 2:A-C-E-F between source node A and destination node F,
Path 3:A-D-F.
Source node A sends detection report along equative route 1, equative route 2 and the equative route 3 of the node F that achieves the goal respectively
Text, probe messages carry parameter collection mark and return to mark, and probe messages one node of every arrival can then collect the node
Node identification and node-node transmission parameter, destination node F identify and return after receiving the probe messages that three equative routes are sent
Mark is returned, then the destination address information and source address information of probe messages is interchangeable, probe messages is returned into source node
A。
Source node A receives the probe messages of return from equative route 1, equative route 2 and equative route 3 respectively.From equivalence
The exit port bandwidth availability ratio that node A is carried in the probe messages for the return that path 1 receives is the exit port of 40%, node B
Bandwidth availability ratio is 50%, the exit port bandwidth availability ratio of node E is 90%；The detection of the return received from equative route 2
The exit port bandwidth availability ratio of carrying node A is 30% in message, the exit port bandwidth availability ratio of node C is 40%, node E
Exit port bandwidth availability ratio is 90%；The exit port band of node A is carried in the probe messages of the return received from equative route 3
Wide utilization rate is 30%, the exit port bandwidth availability ratio of node D is 50%.
The maximum node-node transmission parameter of equative route 1 is that 90%, the maximum node-node transmission parameter of equative route 2 is also
90%, the maximum node-node transmission parameter of equative route 3 is 50%.Assuming that preset threshold is 60%, then the maximum section of equative route 1
Point configured transmission and the maximum node-node transmission parameter of equative route 2 have been above preset threshold, then need to carry out traffic sharing, will
Data traffic on equative route 1 and/or equative route 2 is shared to be transmitted on equative route 3.
Since equative route 1 is equal with the maximum node-node transmission parameter of equative route 2, then compare equative route 1 and equivalence
The secondary big node-node transmission parameter in path 2, equative route 1 time big node-node transmission parameter are 2 times 50%, equative route big sections
Point configured transmission is 40%, accordingly, it is determined that the path load of equative route 1 is most heavy, the path load of equative route 3 is most light.
The data traffic for walking equative route 1 has 3 forwarding-table items of hit, counts the hit-count of this 3 forwarding-table items,
Hit-count is higher, and data traffic transmission occupancy is also bigger under normal circumstances, for example, the hit-count of first forwarding-table item
At most, be 20 times, corresponding data traffic transmission occupancy is 20%, second and third forwarding-table item hit-count compared with
It is few, it is 10 times, corresponding data traffic transmission occupancy is 10%.First that the data traffic of equative route 1 will be walked turns
The next-hop of forwarding list item replaces with away the next-hop of the forwarding-table item of the data traffic of equative route 3, so that number on equative route 1
It shares according to the data traffic that flow transmission occupancy is 20% to transmitting on equative route 3, then each equivalence road after traffic sharing
The segment transmission parameter of diameter is as shown in figure 4, alleviate the Congestion Level SPCC of E-F section.
It is directed to the case where node-node transmission parameter is timestamp, maximum node configured transmission is node time delay, Ke Yitong
The difference for crossing the timestamp of two neighboring node is calculated, subsequent judgement, the treatment process of traffic sharing and node-node transmission
Parameter is that the treatment process in the case where exit port bandwidth availability ratio is similar, is referred to examples detailed above, no longer illustrates here
