Description

Service channel bandwidth management method, related device and system in access network

The present invention relates to the field of communications, and in particular, to a service channel bandwidth management method, related device and system in an access network. Background technique

The Triple Play service refers to multiple different service access modes on one subscriber line. At present, the most common is to provide high-speed Internet access services, VoIP (voice over Internet Protocol) services, and IPTV (Internet Protocol Television) services. The purpose of the Triple Play service is to encapsulate the Internet access service, VoIP, and IPTV services on a single broadband connection to facilitate user access and reduce the maintenance cost of the carrier. Currently, the triple play mode and multiple PVC multi-service services can be used. The Triple play mode of PVC multi-service is realized.

A single virtual circuit (PVC) refers to a terminal that uses a unique PVC channel to carry a variety of different services from the access device to each digital subscriber line (DSL) terminal. On the user side, the VoIP service, the IPTV service, and the Internet access service are accessed by the same PVC. Each xDSL port is configured with one PVC. On the network side, by configuring the uplink interface, the three services are different. Local area network (VLAN).

Multi-PVC multi-service refers to the use of multiple PVC channels to carry multiple services from access devices to each DSL terminal. On the user side, the VoIP service, the IPTV service, and the Internet access service are respectively accessed by different PVCs. Each xDSL port is configured with at least three PVCs. On the network side, the three interfaces are configured to allow the three services to pass. Different virtual local area networks (VLANs) are uplinked.

As the bandwidth requirements of different services are different, the carrier needs to allocate a bandwidth-limiting policy for different services. The current mode is to set different traffic channels to be bound to different traffic profiles in the access device. The Committed Access Rate value specifies the upstream and downstream bandwidth in the traffic profile.

However, in the foregoing solution, after the traffic profile is bound to each service channel, the bandwidth of the service channel is fixed, and the maximum value cannot exceed the CAR limit value of the bound traffic template, and the flexibility is poor. Summary of the invention

Embodiments of the present invention provide a method, a related device, and a system for managing a service channel bandwidth in an access network.

In order to make the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments are merely a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The following describes the method for managing the bandwidth of the service channel in the access network provided by the embodiment of the present invention. Referring to FIG. 1 , an embodiment of the method for managing the bandwidth of the service channel in the access network provided by the present invention includes:

In the embodiment of the present invention, different service flows are carried on different service channels, and the user equipment implements the corresponding service flow by accessing the service channel. Access, a service channel can be a separate PVC identified by a Virtual Path Identifier (VPI) and a Virtual Channel Identifier (VCI), or it can be a PVC under the user. VLANs, priorities, and encapsulation types to distinguish between different channels. In the embodiment of the present invention, the access device is connected to at least one user equipment through a port, and the access device may include one or more ports, which are respectively identified by different port numbers, and each port may be configured according to service requirements. Or more than two service channels, respectively, for carrying different service flows. The port in the embodiment of the present invention includes at least two service channels, and the service channel bandwidth management device detects the service uplink and downlink status of multiple service channels on one port of the access device, for example, assuming that one port of the access device is configured On the Internet service channel and the multicast service channel, the service channel bandwidth management device detects the status of the service on the Internet service channel and the multicast service channel on the port. Specifically, which service channels need to be detected. According to the actual situation, it is not limited here.

102. When it is detected that the status of the service line of at least one service channel on the port changes, the upper limit of the bandwidth of the service channel on the port is adjusted.

The operator sets an initial bandwidth upper limit for each service channel on the access device port for different services. The upper limit of the bandwidth can be specified by the Committed Access Rate (CAR) value. In the embodiment of the present invention, the bandwidth restriction of the service channel is implemented by binding the service channel to a Committed Access Rate (CAR) template with a corresponding CAR value.

When it is detected in step 101 that the status of the service uplink and downlink on at least one service channel on the port is changed (that is, the service in the service channel changes from the online state to the offline state, or from the offline state to the online state), Adjust the bandwidth limit of the service channel on the port. The method for adjusting the bandwidth upper limit of the service channel may be to bind the service channel that needs to adjust the current bandwidth upper limit value from the first committed access rate template to the second committed access rate template, where the first committed access rate is The CAR value of the template corresponds to the current bandwidth upper limit value of the service channel, the CAR value of the second committed access rate template corresponds to the target bandwidth upper limit value of the service channel, and the CAR value of the first committed access rate template is The CAR value in the second committed access rate template is not equal. Alternatively, the CAR value of the CAR template currently bound to the service channel can be directly modified according to the target bandwidth limit of the service channel to be adjusted.

In the embodiment of the present invention, the total bandwidth upper limit of all service channels on one port of the access device is less than or equal to the total bandwidth that can be used by the port.

In the embodiment of the present invention, an operator may target multiple service channels on an access device port according to requirements. The combination of the uplink and the downlink state, the corresponding bandwidth adjustment information is set for each combination, and the bandwidth adjustment information includes the target bandwidth upper limit value of each service channel on the port, and when the port 101 detects that there is at least one service on the port, When the status of the service line of the channel changes, the service determines the bandwidth adjustment information according to the status of the service line of the multiple service channels on the port that is currently detected in step 101, and the bandwidth adjustment information is used according to the found bandwidth adjustment information. The bandwidth limit of the service channel is adjusted. Alternatively, the service channel bandwidth management device can directly release the bandwidth of the service channel where the service that is not currently online is located, and allocate the released bandwidth to at least one current online service when detecting the transition of the service line status of the service channel. The service channel, or the bandwidth to be released is preferentially allocated to the service channel where the service currently being online is located. It can be understood that the bandwidth of the service channel in which the service is not currently online is released should be smaller than the original bandwidth of the service channel; The service channel bandwidth management device can also comprehensively analyze the service priority and the service bandwidth requirement of the online service when the status of the service line of the service channel changes, and improve the uplink service with higher service priority and larger service bandwidth requirement. The upper limit of the bandwidth of the service channel, and the upper limit of the bandwidth of the service channel where the service is lower, or the total bandwidth of the service channel where the service is not online. For business priority High, but the bandwidth requirements of smaller businesses where the business channel, the bandwidth limit can not be adjusted traffic channel business.

In an actual application, in order to prevent the step 102 from being repeatedly performed by the service, the service may be started in step 101, and the timer of the preset duration may be started. When the timer expires and all services are changed. Step l 102 is executed only when the status of the service of the channel is not changed again.

The access device of the present invention may be in the form of an XDSL access mode or a passive optical network (PON) access mode. The service channel bandwidth management device in the embodiment of the present invention may be independent. The device may be the access device itself, and the access device may be, for example, a Digital Subscriber Line Access Multiplexer (DSLAM) or an optical line terminal (OLT). There is no limit.

It can be seen that, in the technical solution provided by the embodiment of the present invention, the service uplink state of at least one service channel on the port of the access device is detected, and the state of the service line of at least one service channel on the port is detected to be changed. Adjust the bandwidth limit of the service channel on the port Integral, provides a dynamic adjustment mechanism for the bandwidth limitation of the service channel, which greatly improves the flexibility of the service channel bandwidth limitation. At the same time, it also avoids the waste of network bandwidth caused by the service channel when there is no service transmission.

202. Determine whether the status of the service uplink and downlink of at least one service channel on the port of the access device changes. If yes, go to step 203. If no, go back to step 201.

203. Detecting, in the preset duration, whether the service uplink and downlink status of all the service channels that have undergone the transition are changed again;

The service channel bandwidth management device starts a preset timer, and detects whether the service uplink and downlink status of all the service channels that have undergone the transition are changed again when the timer expires, and if yes, returns to step 201, and if not, executes Step 204.

204. Obtain a combination identifier according to the status of the service uplink and downlink of the multiple service channels on the port that is currently detected.

In the embodiment of the present invention, the corresponding combination identifier is set in advance for the service uplink and downlink state combination of the multiple service channels on the access device port. For example, if there is no service channel 1 and service channel 2 on the port, The combination identifier 1 corresponds to the combination of the service uplink of the service channel 1 and the service of the service channel 2; the combination identifier 2 corresponds to the combination of the service of the service channel 1 and the service of the service channel 2; 3 corresponds to the combination of the service line of the service channel 1 and the service line of the service channel 2. Of course, different combinations may be set to correspond to the same combination identifier, which is not limited herein.

205. Search for bandwidth adjustment information according to the combination identifier.

For VoIP services, the occupied bandwidth is relatively small, but the requirements for delay are relatively high. If the delay is too large, there may be problems such as echo generation, which affects voice quality, so Internet services, IPTV services, and VoIP are available. Among the three different services, the VoIP service has the highest priority; the IPTV service occupies a relatively large bandwidth, and the BER/BPDU rate is relatively high, because if the IPTV service is If the bit error rate is too large, or the packet loss rate is too large, the video frame will be lost, resulting in mosaic of the image effect. Even if the screen is displayed, the viewing effect will be affected, and the Internet service is generally used to browse the web. The requirements for real-time performance are not strong, and the requirements for packet loss rate are not as high as IPTV (because there is usually a retransmission mechanism to ensure the reliability of transmission). Therefore, the priority of IPTV services is higher than that of Internet services. But it has lower priority than VoIP services.

S3 corresponds to the case where the Internet service is online, and the IPTV service and the VoIP service are not online. The combination identifier s4 corresponds to two cases: one is that the Internet service and the IPTV service are online, the VoIP service is not online, and the other is the Internet access. The service and VoIP services are not online, and the IPTV service is online. The combination identifier s5 corresponds to two cases: one is that the Internet service and the IPTV service are not online, the VoIP service is online, and the other is that the IPTV service is not online. The online service and the VoIP service are both online. The combination identifier s6 corresponds to two cases: one is for the IPTV service, the Internet service, and the VoIP service are online, and the other is for the Internet service, the Internet service, and the VoIP service. On the line.

When the access device is started, each service channel on the two ports is bound to the corresponding CAR profile according to the initial bandwidth limit value, and the service uplink and downlink status of each service channel on the same port is detected. If the service status of the service line of at least one service channel on the port changes, and the service status of all service channels that have changed during the preset time is no longer changed, each service channel of the port is detected according to the current detection. The combination of the service status of the service line obtains the combination identifier, and re-binds the CAR template of the service channel that needs to be adjusted according to the bandwidth adjustment information corresponding to the combination identifier. Tables 4 and 5 show the binding of the 0/8/0 port and the 0/9/0 port to the corresponding CAR template under various combinations of states.
