Fig. 5 is the process of bottom-up passive service customization.The method is triggered by service identification module, comprises the following steps:
1st step, service generation.
First business arrives, described resources detection module 21 detects the business data flow of access, business data flow newly-increased in this way, then outgoing traffic access state information S to QoS controller, service identification module 12 is according to described service access state information S identification services information and user profile; Custom service in this way, then switching control module controls skewing mechanism, make to come from business network interface SNI 1, SNI 2, the customer service signal of SNI N forwards by the switching path of specifying, and outputs to corresponding PON interface, in intersection and access adaptation procedure, distribute suitable bandwidth for this customer service signal.
2nd step, QoS of survice customize.
After QoS controller receives the information of underlying device transmission, QoS processing module inquiry custom service database, if this service customizing information is present in database, then requires according to customization and network real-time status execution custom service QoS Optimization Mechanism, form high priority strategy; If do not exist, then perform non-customized QoS of survice Optimization Mechanism according to network real-time status, form low priority strategy.Finally form priority list and bandwidth demand list.
3rd step, execution custom strategies.
Described resource distribution module 15 determines according to described service priority and bandwidth demand the Resource Allocation Formula meeting business demand, send Resourse Distribute control command A to OLT switch, upgrade OLT switch local exchange control module 22, change skewing mechanism 24, distribute suitable bandwidth for customer service and make to come from business network interface SNI 1, SNI 2 ... the user service data of SNI N forwards by the switching path of specifying, and outputs to corresponding PON interface.
The method that bottom-up passive service customizes is explained below for a practical application scene, suppose that COM company has opened the custom service of a Remote Video Conference, the user that have purchased this custom service can enjoy the video conference service of secure low time delay high definition on common wide circuit.The relevant information of this custom service that so COM company opens just comprises: videoconference traffic characteristic information H, the user that have purchased this service, customization priority.
First videoconference traffic arrives OLT, resources detection module detects the said firm videoconference traffic characteristic information H, retrieval local data finds do not have business, then the characteristic information H of data flow and information of terminal user are reported QoS controller, QoS controller is according to the characteristic information H received and user profile inquiry business customized databank (must characteristic information H and user profile mate) simultaneously, have found the customized information that COM company formulates, concrete qos policy is formulated again according to the real-time status of current network, comprise the bandwidth (decision transmission rate) of actual allocated, queue priority (decision propagation delay time), Resource Allocation Formula is formed according to the current occupation condition of network, finally be handed down to OLT.
Fig. 6 is the process of top-down active business customization.Triggered by business customizing module, comprise the following steps:
1st step, service generation.
First user is opened by interaction platform or revises custom service service, and business customizing module is according to the instruction identification services information of user and user profile.
2nd step, QoS of survice customize.
Condition (or other conditions) on schedule, QoS controller upgrades described custom service database 14, the service customizing information service customizing information provided according to user again and network resource status perform custom service QoS Optimization Mechanism, produce the business Qos strategy of high priority, finally form priority list and bandwidth demand list.
3rd step, execution custom strategies.
Condition (or other conditions) on schedule, resource distribution module determines according to service priority and bandwidth demand the Resource Allocation Formula meeting business demand, Resource Allocation Formula is handed down to OLT switch, and upgrade OLT switch local exchange control module, come from business network interface SNI 1, SNI 2, the customer service of SNI N is once be identified, namely forward by the switching path of specifying, output to corresponding PON interface, for this customer service distributes suitable bandwidth in intersection and access adaptation procedure.
Such as at application scenarios as described above, first certain company submits its custom service demand on service delivery platform, and pay according to the grade of service, the customized information that the said firm submits to just comprises the said firm's videoconference traffic characteristic information, buys the user of this service, customizes priority.With regard to real-time update custom service database after service customizing information formulation, then concrete qos policy is formulated according to the real-time status of current network, comprise the bandwidth (decision transmission rate) of actual allocated, queue priority (decision propagation delay time), the all OLT finally relating to this policy distribution to this custom service, OLT upgrades local data base, then goes to distribute bandwidth according to Resource Allocation Formula.
