Embodiment
The transmission that appears as Streaming Media of ASON ASON provides good platform, it with optical fiber as transmission medium, introduce WDM (wavelength division multiplexing, Wavelength Division Multiplex), SDH (synchronous digital network, Synchronous Digital Hierarchy) etc. technology can satisfy huge bandwidth demand; The characteristic of its light path exchange can reduce to delay time, the influence of packet loss etc., and utilizing ASON to make up towards the network platform of multimedia service is the development in future direction, can provide a kind of realization thinking for VOD service.
Among the present invention, server and client side with video request program, respectively by the MSTP (multiservice transport platform in the ASON network, Multiple Services Transaction Platform) UNI-C (the User Network Interface-Client of veneer and ASON network, the User Network Interface client) equipment connects, thereby carries out video request program by the ASON network.
As shown in Figure 1, undertaken by ASON comprising User Network Interface client device UNI-C and apparatus for network node in the ASON in the system of video request program, also comprise the ordering server, the video request program client that link to each other with described UNI-C equipment;
The node device of described ASON, be used for setting up Ethernet private line service, transmitting video data at the User Network Interface client UNI-C equipment that connects ordering server with the User Network Interface client UNI-C equipment room that is connected the video request program client.This node device is UNI-N (User Network Interface-Network, User Network Interface network terminal), or Network-Network interface node NNI, and NNI is divided into internal network node interface INNI and external network node interface ENNI.
UNI-C equipment is used for multiservice transport platform MSTP veneer is installed, and the interface of described multiservice transport platform MSTP veneer being set to general frame forming standard GFP pattern when being connected with ordering server or video request program client.
As shown in Figure 2, method specifically may further comprise the steps among the present invention:
Connect each node in the ASON network with optical fiber, and dispose each node it can both normally be moved;
The main effect of MSTP veneer is IP (the Internet Protocol with video request program, procotol) packet, convert the Frame in the ANON transmission network to, be sent to the ANON transmission network, or convert the Frame of ANON transmission network the IP packet of video request program to, be sent to ordering server or video request program client.
After the UNI-C node is installed the MSTP veneer, the veneer association attributes is set; As VCG (virtual cascade group, Virtual Concatenation Group), LCAS (link capacity adjustment, Link CapacityAdjustment Scheme).
By the setting of VCG and LCAS attribute, can in video request-program process, on the UNI-C node video data be mapped on system's usable bandwidth resources automatically, thereby avoid complicated manual circuit interconnection configuration, improve the dispensing rate of bandwidth; Also help simultaneously and enable idle protection capacity in traditional SDH net, improve the utilance of bandwidth resources.
Ordering server is connected to the MSTP veneer of a UNI-C node by optical fiber (for example kilomega optic fiber), and the encapsulation mode of the interface of MSTP veneer is set to GFP (Generic FramingProcedure general frame forming standard) pattern.Except the GFP pattern, can also be set to PPP (Point-to-Point Protocol, peer-peer protocol) or LAPS (Link AccessProcedure-SDH, the Link Access Procedure on the SDH).
Use the GFP encapsulation mode that following advantage is arranged:
(1) uses the encapsulation of GFP pattern, can realize in link, transmitting simultaneously the packet of regular length and variable-length, and respectively fixed length and random length data are optimized;
(2) use the encapsulation of GFP pattern, can pellucidly various data-signals be encapsulated as the signal that can in existing transmission network, effectively transmit, thereby realize statistic multiplexing and the qos feature of user data.
(3) use the encapsulation of GFP pattern, the data load-carrying efficiency on the transmission link can not be subjected to the influence of flow rate mode, has higher data encapsulation efficient.
The video request program client is connected to the MSTP veneer of another UNI-C node by kilomega optic fiber, single board interface is set equally uses the GFP encapsulation mode.
The single board interface encapsulation mode of the UNI-C equipment that is connected with ordering server with the video request program client is identical, all use GFP pattern, PPP pattern or/the LAPS pattern.
Management plane by ASON issues the order of creating the EPL business; The control plane of ASON network node is set up the relevant internodal EPL service channel of UNI-C.
Detect the EPL business and whether create success, can detect the UNI-C equipment that connects ordering server and whether communicate between the UNI-C equipment that connects the video request program client.
In another embodiment, in step 202, can between ordering server or client and UNI-C node device, increase extras (as router) and finish the data transaction that the IP packet of video request program is converted to the Frame in the transmission network; In step 205, set up the relevant internodal EPL service channel of UNI-C by these extras (as router).These two kinds of methods are compared, and the method for use MSTP veneer can reduce cost and reduce the complexity of system.
The present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the present invention, and these change and be out of shape the protection range that all should belong to the appended claim of the present invention accordingly.
