The present invention is in order to solve the drawback that conventional solution exists, by the further configuration method for service quality parameters of setting forth in a kind of Ethernet passive optical network of the present invention of following examples, below embodiment is described in detail, but not as a limitation of the invention.
In the described method of the embodiment of the invention, configuration service mass parameter on optical line terminal, Optical Network Terminal and optical network unit carry out the selectivity configuration according to described QoS parameter then, and configuration result is sent to optical line terminal; Optical line terminal is adjusted QoS parameter according to described configuration result.
As shown in Figure 1, a kind of concrete enforcement of the method for the invention based on the structure chart of EPON system.
Ethernet passive optical network (EPON) is the single fiber bi-directional Optical Access Network that multiple spot (P2MP) structure is put in a kind of employing, and its canonical topology structure is the tree type.
The EPON system is made up of the optical line terminal (OLT) of network side, the optical network unit (ONU) and the Optical Distribution Network (ODN) of user side, is the optical fiber bidirectional system.
At down direction (OLT is to ONU), the signal that OLT sends arrives each ONU by ODN.
At up direction (ONU is to OLT), the signal that ONU sends only can arrive OLT, and can not arrive other ONU.
For fear of data collision and increase network utilization, up direction adopts the TDMA access mode and the data of each ONU is sent and arbitrates.ODN is made up of Passive Optical Components such as optical fiber and one or more passive optical splitters, provides optical channel between OLT and ONU.
As shown in Figure 2, a kind of concrete enforcement of the method for the invention comprises following five stages:
One, configuration phase, configuration QOS parameter on OLT usually.
In these parameters, mainly contain service stream classification parameter, priority flag parameter, queuing and scheduling parameter, ductility limit speed parameter, traffic shaping and flow management parameter, congestion-avoidance parameter, cache management parameter etc.
The service stream classification parameter comprises: the UNI of ONU (user side interface) port, VLAN ID (VLAN identification code), LLID (multicast LLID), MAC (medium access control) address, IEEE802.1D User Priority, Ethernet (Ethernet) type, IP (procotol) address, IP type, IP TOS/DSCP, L4 protocol port etc.Also can carry out traffic classification by the mode of configuration DPI (deep-packet detection).
Behind the traffic classification, the business that distinguishes is carried out the flag parameters configuration of priority, mainly contain up IEEE802.1D User Priority parameter etc., also optional IP TOS (COS) or DSCP (differentiated services code points) etc.
After marking stream, then can carry out the configuration of formation and scheduling parameter, and bandwidth constraints parameter, different flow shaping algorithm, the control mode parameter of corresponding stream, congestion avoidance algorithm and distribute the isoparametric configuration of corresponding spatial cache.
Can increase mandatory attribute or select attribute for these parameters that issue, for the parameter that has increased mandatory attribute (mandatory parameters), when the equipment that receives parameter need be configured according to the content of parameter, and for having increased the parameter (selection parameter) of selecting attribute, the equipment that receives parameter can be selected configuration according to self-condition.
In the present embodiment, the QOS parameter configuration is to finish on OLT, in other embodiment, can be put into the QOS parameter on OAM (operation management maintenance) system or other special QOS servers or the strategic server and dispose, OLT can get access to these configuration parameters from these systems.For ONU or ONT the corresponding default configuration can be arranged all generally, these configurations will also will use in follow-up negotiations process.
Two, deploy content sends the stage, when ONU/ONT enters network, consult with OLT and registration after, OLT will be on the ONU/ONT after being issued to registration in configuration phase configured QOS parameter;
Three, the configuration phase of ONT/ONU after ONT/ONU receives institute's configured QOS parameter that OLT issues, is selected and is disposed the parameter that issues;
The QOS parameter that OLT issues is divided into two types: mandatory parameters and selectivity parameter, and generally, the mandatory parameters that OLT is issued is configured as the default configuration parameter;
And for selectivity parameter, the selection that the equipment that receives the QOS parameter carries out parameter according to the disposal ability of oneself is configured;
Four, the report stage after the ONT/ONU configuration is finished;
Because ONT/ONU selects the selectivity parameter that receives in the stage three and disposes, in this stage, ONT/ONU reports to OLT with final configuration parameter;
Described configuration parameter report comprises parameter that the selected need of ONT/ONU are configured and the content of parameter that is disposed;
Five, the OLT parameter adjustment stage;
In this stage, OLT is according to described configuration parameter report carrying out QOS parameter adjustment;
In the EPON system, there is difference in the QOS parameter of uplink and downlink direction.
On up direction, whether selected configuration of selectivity parameter, when the selected configuration of selectivity parameter, its parameter value will be determined by ONU/ONT, the uni port during traffic classification for example, ONU/ONT can determine that the port of UNI is to insert video, speech or business of networking.
Therefore, after ONU/ONT determines institute's configured QOS parameter, form the configuration parameter report and be sent to OLT; The selected configured QOS parameter that report is carried according to described configuration parameter and the content of parameter of configuration, OLT adjusts the QOS parameter of himself.
By above five stages, can finish the negotiation and the configuration effort of the QoS parameter between OLT equipment and the ONU/ONT, simultaneously owing to consider the characteristic of concrete ONU/ONT equipment, but carry out arrangement for some parameter, make that the allocative efficiency of QOS relevant parameter is higher, also can have more usability, thereby improve the interoperability of QOS parameter, the service quality when satisfying the user and using miscellaneous service guarantees.
In networking diagram as shown in Figure 3, be connected to PC (personal computer), phone and set-top box, TV among the figure under the ONT equipment.PC represents common business of networking, and on behalf of speech business and set-top box, phone represent video traffic.
The flow chart of Fig. 4 is to be that service stream classification parameter and priority flag parameter are another concrete implementation procedure of implementing of example explanation the method for the invention with the QOS parameter.
Service stream classification is meant according to some characteristic information in equipment or the bag data flow of access arrangement is divided, thereby identifies different service traffics.
Priority flag then is meant different packets is carried out different priority flags, to mark the packet corresponding priorities, so that other equipment or subsequent treatment.
Idiographic flow is described below:
When configuration phase, disposed service stream classification parameter and priority flag parameter,
The for example uni port of ONU, VLAN ID, LLID, MAC Address, IEEE802.1D User Priority, Ethernet type, IP address, IP type, IP TOS/DSCP, L4 protocol port, and set these parameters for selecting attribute;
Configuration preference level flag parameters is an example with the 802.1D User Priority for example, is mandatory parameters with the parameter setting shown in the following table:
| UserPriority (owner priority) | Type of service | Remarks |
| 7 | Network Control (network control) | Comprise TDM |
| 6 | Internetwork Control (internet control) | ? |
| 5 | Voice (＜10ms latency and jitter) (audio frequency＜10ms stand-by period and shake) | VoIP (networking telephone) |
| 4 | Video (＜100mslatencyand jitter) (video＜100ms stand-by period and shake) | IPTV (network), video |
| 3 | Critical Applications (the crucial application) | ? |
| 2 | Excellent Effort (beneficial effect) | ? |
| 1 | Background (background) | ? |
| 0(Default) | Best Effort (optimum efficiency) | Common business of networking |
When deploy content sends the stage, when ONT enters network, consult with OLT and registration after, OLT will be on the relevant configuration down sending content of the service stream classification parameter of configuration phase and the priority flag parameter ONT after the registration;
When the configuration phase of ONT, after ONT receives the QOS parameter that OLT issues, the parameter that issues is selected and disposed.
Because the 802.1D User Priority parameter that is issued is set to mandatory parameters, so ONT adopts these parameters.
And for the service stream classification parameter that issues, because it is an optional parameters, after this locality configuration and ability in conjunction with ONT oneself, ONT selects the method for uni port as traffic classification, the port arrangement that promptly meets PC is common business of networking, the port arrangement of answering the call is a voice service, and the port arrangement that meets STB (top box of digital machine) is a video traffic.These three kinds of streams adopt compulsory 802.1D User Priority parameter to shine upon when being mapped to 802.1D User Priority mark, and packet are carried out the mark processing of priority;
During report stage after ONT configuration is finished, ONT reports to OLT equipment to oneself final configuration parameter, as service stream classification parameter and the mandatory parameters that receives;
The parameter of the relevant configuration that receives this ONT equipment is adjusted according to the configuration parameter of ONT report at OLT, thereby finished final layoutprocedure.
By above step, the QoS parameter of having finished between OLT and the ONT is consulted and layoutprocedure, thereby because the consistency of the selection of parameter consistency when having guaranteed to handle, improved the interoperability of QOS parameter between distinct device, finally the quality of service for the user provides good assurance.
The described method of the embodiment of the invention need not adopt complicated agreement and realize the consistent of QOS parameter of OLT, ONU, ONT (Optical Network Terminal) disposed, simplify the negotiation mechanism of QOS, satisfy the disposal ability and the characteristics of various device as much as possible, improve the interoperability of QOS in equipment, thereby provide better service quality for the user.
