Detailed description of the invention
Below in conjunction with Figure of description, describe the detailed description of the invention of the present invention in detail.
The invention discloses a kind of communication network various dimensions resources regulation method based on SDN framework, its specifically include with
Under step:
Step one, for network needs regulation and control device build device model, extract distinct device relevant parameter, be mapped as one
Overlap unified parameter type, as required, can use and refer to that type and the weights of monitoring parameter are customized by parameter model.
Refer to that parameter model is can be customized according to the demand of current system, the most in systems concerned about network transmission speed
Rate, it is possible to the parameter extracting equipment needs monitoring is: device type (such as: optical switching device, electricity switching equipment) (weights
0.4), equipment supports bandwidth (weights 0.3), equipment entrance speed and equipment egress rate (weights 0.2), equipment delay shake
(weights 0.1) etc..To different application scenarios, if value is the expense of transmission reliability or transmission, may extract
Parameter type and weights are the most different, and these needs are analyzed according to concrete application scenarios.
Step 2, controller obtained by Network Topology Discovery Algorithm and safeguard network topology (for example with based on
The physical network topology algorithm of Link Layer Discovery Protocol (LLDP)), generate logical topology chart, controller by OpenFlow,
SNMP, special equipment management agreement (different systems may have different management agreements) etc. obtain network performance parameter, coupling
Local device model, and the mapping function performance data first arranged of acting is normalized.This model, mapping are closed
System and normalized are all according to concrete application scenarios oneself definition, and in same system, same category of device is (such as: exchange sets
Standby, transmission equipment, terminal unit etc.) model parameter content, span identical, but mapping relations the most of the same race set due to similar
Standby (such as optical switching device, electricity switching equipment) parameter is variant, and therefore mapping relations need to make respectively according to each autoregressive parameter of equipment
Fixed.
Now it is exemplified below in conjunction with the present invention:
Model: based on the demand structure local device model element that transfer rate is preferential: link degree of stability (weights 0.4), maximum
Bandwidth (weights 0.3), loads (weights 0.2), time delay (weights 0.1).
Mapping relations:
Link degree of stability (switch kind equipment)=(local device type+opposite equip. type) × port status；Wherein gigabit electricity
Switching equipment, 10,000,000,000 electricity switching equipment values are 1, and optical switching device is 2, and port is normally 1, and port is 0 extremely；
Maximum bandwidth=equipment supports bandwidth；
Load=go out port data flow；
Time delay=preset according to device type: gigabit electricity switching equipment value 0.2,10,000,000,000 electricity switching equipment value 0.25, light is handed over
Exchange device 0.4；
Bandwidth related data unit on the basis of gigabit, i.e. every gigabit is set to 1 unit；
Control equipment obtains a following parameter of electric switching equipment by management agreement: maximum supports bandwidth 1KM, enters end in 30s
Mouth data traffic 0.3Mbps, rate of discharge 0.3Mbps, port status are normal, and opposite equip. is electricity switch.
This device model is mapped as:
Link degree of stability=2；
Maximum bandwidth=1；
Load=0.3；
Time delay=0.2；
Each parameter is i.e. weighted processing by normalized, and this device value is 1.18.
Step 3, SDN controller according to a moment history value in each dimension values comparison of joint behavior (initial value is 0),
Calculate the modifying factor of each dimension of node, the preferential and preferential two class situations of transmission reliability in conjunction with prior Preset Transfer speed
Each dimensionality weight, use shortest path first obtain Optimization route, delete this Optimization route, rerun and obtain sub-optimal road
By, preserve that defeated speed is preferential and transmission reliability four routing iinformations of preferential two class (two class situations calculate possible outcomes possibility phases
With), and by the optimum route sending-down network equipment.
The correction value of each dimension is described: the only dimensional information to affected networks situation introduces historical data to represent net
Network development trend, reduces the impact of bursty data, and smooth dimension statistical value, this value is exactly modifying factor, in the present invention: chain
Road degree of stability, maximum bandwidth, load, time delay four dimensions value, only link degree of stability and load become with Network Situation change
Changing, they have modifying factor, and another two value is determined by the attribute of equipment own, and therefore, their modifying factor is fixing is set to 1.
Modifying factorLink degree of stability=；
Modifying factorLoad =；
Efficiency of transmission is preferential and transmission degree of stability is preferentially to efficiency of transmission and the shadow of transmission degree of stability according to each modifying factor
Ring and be weighted again, during such as efficiency of transmission is preferential: modifying factorLink degree of stability× 0.5+ modifying factorLoad× 0.5, and transmit stable
Modifying factor in degreeLink degree of stability× 0.8+ modifying factorLoad×0.2。
Business datum is stamped feature tag according to traffic performance by step 4, upper level applications, sets through matching network
Standby default routing iinformation, carries out message forwarding.The foundation that formed of feature tag is to carry out specific fields the most in messages
Coupling, field can be the protocol fields in IP message, source IP, purpose IP, TOS field, the one of udp port field or several
Kind, being also likely to be some or several field in coupling UDP load for some upper layer application message, equal to particular value, is such as
Short message (traffic guidance's data) in system is fixing uses 5566 ports, and long message (communication document) uses Transmission Control Protocol, and agreement is just
Literary composition 0X1001 identifies, and uses the peer-port field of UDP to mate short message data and the protocol fields of IP protocol header and UDP load
The first two byte mates long message data jointly, and these information can be illustrated by XML configuration file.Then according to business demand
(such as: transfer rate is preferential or transmission reliability is preferential), transmission feature are (such as: institute will need bandwidth and urgency level to be mapped as preferentially
Level) form feature tag, it is labeled in business datum.When upper layer application is uncontrollable, it is impossible to business datum to be labeled operation,
In the case of switching equipment support policy controls simultaneously, it is also possible to above-mentioned information is issued to exchange as equipment regulating strategy and sets
Standby.
Step 5, network routing device are according to controlling equipment prior distributing policy real-time collecting this locality performance data, regularly
Or reporting control equipment after reaching strategy thresholding, planning route is adjusted by control equipment.Control equipment is by local performance
Data calculate route, by OpenFlow agreement, equipment stream table information are issued to each equipment, adjust device forwards path.
The present invention is by providing a kind of communication network resource various dimensions based on SDN framework regulation and control method, by controlling
In the central controlled network of device, network topology situation can be carried out perception by fine granularity various dimensions, carry out complete on this basis
Resource flexible modulation in the range of net, enables upper-layer service to select suitable link, more current usual manner according to self-characteristic
Network Load Balance can be better achieved, it is achieved mode simple possible, it is possible to bigger increases network utilization.Calculate route
Time, the assessment to node is many aspects, is no longer conventional network hops of only seeing, but the unified communication energy considering node
The factors such as power, link-quality, offered load, are therefore various dimensions.The thought of SDN is have employed in network path regulates and controls, by
Control equipment collects the whole network state, combines Network Situation and business demand in the angle of the whole network, calculates the whole network stream table, efficiently spirit
That lives regulates and controls network path rather than relies on routing device self convergence to carry out path adjustment in general networks.Different
Business have different characteristics: such as: commander's instruction, message is short and small, and requirement of real-time is high；Video data, the transmission time is long, real
Time property requires height, can allow a certain amount of data packetloss；Document real-time property is less demanding, but does not allow packet loss, situation
Data, requirement of real-time is high, but can stand certain packet loss, etc., the transmission pathway requirements of network is by these messages
Different.
(succinct for representing, the network equipment is unified as shown in Figure 1 for a kind of communication network topology based on controller centralized management
Routing device identify), controller use management network in the way of out of band data, the network equipment is managed, the network equipment it
Between interconnection there is multiple Linktype.Business network is two different networks with management network in systems, has respective
Address and network connect, and out of band data, that is management network is out of band data for business datum, is not take up business
The resource of network, is therefore outside band.
When network design, network manager is complete the model construction of disparate networks equipment, specifies various kinds of equipment
Monitoring parameter and monitoring strategies, define the abstract mapping algorithm of performance.Such as device type mapping link type, and then take out
Maximum bandwidth, propagation delay time；The cache size of router, queue depth can take out current residual bandwidth；The error code in radio station
Rate, slip rate can take out packet loss etc..Network, at the beginning of offering, will be set by NMP (such as: snmp protocol)
Standby monitoring parameter and monitoring strategies are handed down to each equipment, in order to equipment independently collects processing equipment during the network operation
State.
After network opening, controller, by the way of its all neighbor nodes of the LLDP acquisition of information of device port, uses
Preorder traversal algorithm, obtains all nodal informations in network, completes Network traffic model relation perception.
Or in network initialization procedure, controller sends the LLDP protocol massages of customization, net to network equipment timing
Network management equipment detects transmitting terminal after receiving and controls information, then fill out self information and controller in messages according to local policy
The performance parameter of customization, broadcasts to all neighbor nodes, and neighbor node is left intact after receiving and message is mail to controller,
Annexation and the correlation performance parameters of first equipment of two nodes is obtained, except timing probe after controller analytic message
Outside, controller can also be notified breath according to strategy or equipment master, sends specific probe messages, measures some or many individual characteies
Can be worth, such as, be sent the time stamp received, the time delay of measurement given link by contrast.
Controller synthesis analysis obtains the parameter (parameters such as Network traffic model and the time delay of each node, packet loss, bandwidth
Can revise by user's customized according to network demand with weights), calculate modifying factor, in conjunction with preset each dimensionality weight,
Calculated based on speed and each node cost based on reliability by below equation:(wherein: table
Showing node cost, for preset weights, the dimension values that the parameter reported for equipment obtains after abstract and normalization, for modifying factor
Son).The weights of the node cost each node in routing algorithm.I-th each node during wherein i represents network, value is by net
Network interior joint number determines；The jth dimension of j mark node, the performance parameter that value is monitored by the demand of node (is namely tieed up
Degree) determine.
After calculating each node cost, according to network characteristics, call dijkstra's algorithm or other routing algorithms, for network
In all nodes calculate two optimal paths that speed is preferential and reliability is preferential, and estimate long delay and maximum respectively
Packet loss and the maximum bandwidth supported, according to preset strategy, delete in topology front the 30% of the pack heaviest of optimal path
Intermediate node or the path that calculates have the intermediate node of overlap, again calculates the sub-optimal path of independent in path, by twice meter
Calculate result and be saved in this locality, and optimum is route the form shown in message Fig. 3 by route sending-down to each network equipment；Optimum
Field in the message of route includes destination address, mask, gateway address, port numbers, route-type, routing parameter, route shape
State, route life cycle.After conventional routing table information (first four), also add more fine-grained content, i.e. route-type,
Routing parameter, routing state and route life cycle.
Route-type: which category feature is mark route be based on, 0 represents based on speed-priority in this example；1 represents based on can
Preferential by property；Can extend according to user's request.
Routing parameter: identify the characteristic parameter value of this type of route, when including maximum support bandwidth, maximum in this example
Prolong maximum allowable packet loss, can extend according to user's request.
Routing state: mark route the currently active state.0 represents the currently active in this example, it is allowed to all business datums
The route that bag selects.1 represents that history is effective, and before only allowing, business data flow that is the most chosen and that transmitting selects, and does not permits
The Business Stream of Xu Xin selects, and to reduce the cost that route migrates, then a period of time way of escape is by the most again activating, and this route is reduced to
Lost efficacy route.2 represent and had lost efficacy, but intervalometer not yet triggers the route of deletion action, when can be again after performance recovery
Activate, reduce route oscillation cost.
Routeing life cycle: mark route life cycle, within a period of time, unactivated route will be deleted.
In order to adapt to centralized Control, the upper level applications of user terminal is also required to do adaptability reform, sends at message
Shi Zengjia label function, label function mark is deposited characteristic and the resource requirement of outgoing packet, can be used the TOS field of IP, it is possible to
To specify that in data segment specific fields, total system keep consistent.It is proposed with TOS field (one of which TOS customization side
Formula is as shown in Figure 4), can compatible existing common IP data, when upper level applications does not identify, the network equipment select at random
Routing by, if the routing parameter having route is unsatisfactory for business demand, then network access device refuse business datum, with
The icmp packet of extension informs upper layer application.If this locality does not has required route, can be by first network equipment of business side to control
Route application initiated by device processed.
In TOS field
Precedence type: 1 represents that transfer rate is preferential；2 represent that transmission reliability is preferential, other: standby.
Priority level: 0 is the highest, 8 is minimum, the lowest class (division root of priority level that identification service is able to receive that
According to the demand of use, can be mapped by node cost, it is also possible to mapped by the value of key parameter).
The network equipment, according to self policy monitor performance parameter index, when reaching the threshold value of strategy setting, uses webmaster
Controller report on management agreement, and notice to the forward direction network equipment, routing parameter, routing state equivalence in self-modified routing table.
