Description

Allocation of network resourcesMethod, QoS management network element and application server

[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of network resource management, in particular to a method for allocating network resources, a QoS management network element and an application server.

[ background of the invention ]

There are a variety of network services in a network that are provided by their corresponding application servers. The network service provided by the application server is loaded on the underlying load-bearing network. In order to ensure that the network Service can be normally performed, the application server sets a QoS (Quality of Service) parameter, and the QoS parameter puts forward certain requirements on transmission bandwidth, transmission delay, packet loss rate, and the like, so that the network Service can fully use network resources of the bearer network.

However, network resources of the bearer network are always limited, and when there are a plurality of application servers and the network resources of the bearer network cannot meet the requirements of all the application servers, the bearer network may be congested or overloaded, so that the network service provided by the application servers is affected by bandwidth reduction, time delay increase, packet loss rate increase, throughput reduction, and the like, and the network service of the application servers may also fail.

The inventor of the present invention found in long-term research and development that, when a bearer network is congested or overloaded, the originally set QoS parameter of the application server cannot be changed, that is, the application server still uses network resources according to the originally set QoS parameter. However, the available network resources of the bearer network have been greatly reduced due to congestion or overload, and if the network resources at this time cannot meet the QoS parameter requirements of a certain application server, the network traffic of the application server will fail. On the other hand, even if the network resources can meet the QoS parameter requirements of a certain application server, the remaining network resources are difficult to support the network traffic of other application servers, thereby compromising the benefits of other application servers, which is extremely unhealthy for network resource management.

[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Fig. 1 is a schematic flow chart of a first embodiment of the method for allocating network resources according to the present invention. The method for allocating the network resources comprises the following steps:

step S11: the network status of the bearer network is learned.

The bearer network is at the bottom layer, and defines the physical network interconnection method and the convention of using network resources. The network state of the bearer network can be determined by monitoring at least one of the storage space of the output port of the network node in the bearer network, the channel capacity of the link, the sending rate of the information source, the queuing length of the data packet and the like; or, receiving network state information reported by the bearer network, for example, the bearer network reports the first state identifier when the network state is not congested or overloaded, and the bearer network reports the second state identifier when the network state becomes congested or overloaded. The bearer network includes a fixed network and a mobile network.

Step S12: and receiving the first QoS request parameter from the application server, and inquiring the network state of the bearer network at the current moment.

The application server puts forward a demand on network resources in order to ensure that the network service is normally carried out, wherein the demand is expressed by a first QoS request parameter. For example, the bandwidth occupied by the request in the first QoS request parameter is 2M.

Since the network state of the bearer network can be known at any time before the first QoS request parameter is received, the network state of the bearer network can be immediately inquired at the current moment when the first QoS request parameter is received. The network status is divided into two types, one is congestion or overload and the other is idle or normal. When the network state is congested or overloaded, the bearer network can still provide network resources, but the network performance will be reduced, and if the network state continues to remain congested or overloaded, the network performance of the bearer network will be reduced sharply.

Step S13: and if the network state is not congestion or overload at the current moment, controlling the bearer network to allocate network resources to the application server according to the first QoS request parameter and the network resources of the bearer network.

After the network state is not found to be congested or overloaded, the application server may allocate network resources according to the configuration of the first QoS request parameter, where the allocation of the network resources is subject to the network resources that can be allocated by the bearer network. For example, if the maximum bandwidth that can be provided by the network resource of the bearer network is 3M, the bearer network may be controlled to allocate the 3M bandwidth to the application server.

Step S14: and if the network state of the bearer network becomes congestion or overload after the network resources are allocated to the application server, acquiring a second QoS request parameter, and controlling the bearer network to reallocate the network resources to the application server according to the second QoS request parameter and the network resources of the bearer network, wherein the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter.

After the network resources are allocated, the network service of the application server is in a running state. As mentioned above, the network service can operate normally while occupying 2M bandwidth. However, if the bandwidth that can be allocated by the bearer network drops during a period when the network state suddenly becomes congested or overloaded, network traffic may fail due to the limitation of bandwidth. Therefore, after the network resources are allocated, the network status of the bearer network still needs to be continuously queried.

The network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter, which means that the bandwidth occupied by the request in the second QoS request parameter is less than 2M, for example, 1M. The reallocation of network resources by the application server according to the configuration of the second QoS request parameter may reduce the quality of network traffic of the application server, but may ensure that the network traffic does not fail.

Step S15: and if the network state is congestion or overload at the current moment, reporting the network state to the application server so that the application server sets a second QoS request parameter.

If the network state is already congested or overloaded when the first QoS request parameter is received, the network state is reported to the application server to remind the application server that network service failure may be caused if the application server still occupies network resources according to the first QoS request parameter. If the application server is able to reduce network resource requirements,

step S16: a second QoS request parameter is received from the application server.

Step S17: and controlling the bearer network to allocate network resources to the application server according to the second QoS request parameter and the network resources of the bearer network.

The difference between step S17 and step S14 is that the application server is already using the network resources of the carrier network when the network resources are allocated in step S14, and the application server is not yet using the network resources of the carrier network when the network resources are allocated in step S17.

The method for allocating network resources of the present embodiment receives the first QoS request parameter and the network status of the bearer network is not congested or overloaded, the bearer network is controlled to allocate network resources for the application server in accordance with the first QoS request parameter, acquiring a second QoS request parameter when the network status of the bearer network becomes congested or overloaded later, controlling the bearer network to reallocate network resources for the application server according to the second QoS request parameter, and if the network status has been congested or overloaded when the first QoS request parameter is received, the second QoS request parameter is still acquired, since the network resources required for the second QoS request parameter are less than the network resources required for the first QoS request parameter, therefore, the purpose of reducing required network resources when the load-bearing network is congested or overloaded is achieved, the influence on other application servers can be reduced, and the healthy operation of network resource management is guaranteed.

Fig. 2 is a flowchart illustrating a second embodiment of the method for allocating network resources according to the present invention. The method for allocating the network resources comprises the following steps:

step S21: the network status of the bearer network is learned.

Step S22: a first QoS request parameter is received from an application server.

The application server puts forward a demand on network resources in order to ensure that the network service is normally carried out, wherein the demand is expressed by a first QoS request parameter.

Step S23: and inquiring the network state of the bearer network at the current moment, if the network state is not congestion or overload, performing step S24, and if the network state is congestion or overload, performing step S29.

The network status is divided into two types, one is congestion or overload, and the other is idle or normal. When the network state is congested or overloaded, the bearer network can still provide network resources, but the network performance will be reduced, and if the network state continues to remain congested or overloaded, the network performance of the bearer network will be reduced sharply.

Step S24: and setting a first QoS distribution parameter for the application server according to the first QoS request parameter and the network resource of the bearer network.

Step S25: and controlling the bearing network to allocate the network resources required by the first QoS allocation parameter to the application server.

When allocating the network resource, the network resource may not be allocated completely according to the requirement of the first QoS request parameter. For example, the maximum bandwidth that can be provided by the network resource of the bearer network is 3M, and the bandwidth requested to be occupied in the first QoS request parameter is 2M, then the bandwidth requested to be occupied in the first QoS allocation parameter is 2M through allocation setting, and the application server will obtain the 2M bandwidth. If the maximum bandwidth that can be provided by the network resource of the bearer network is 1.5M, the bandwidth required to be occupied in the first QoS allocation parameter is 1.5M through the allocation setting, and the application server will obtain the bandwidth of 1.5M. That is, the network resources required by the first QoS allocation parameter are no more than the network resources that the bearer network can allocate.

Step S26: if the network state of the bearer network is continuously inquired after the network resources are allocated to the application server.

After the network resources are allocated, the network service of the application server is in a running state. As mentioned above, the network service can operate normally while occupying 2M bandwidth. However, if the bandwidth that can be allocated by the bearer network drops during a period when the network state suddenly becomes congested or overloaded, network traffic may fail due to the limitation of bandwidth. Therefore, after the network resources are allocated, the network state of the bearer network still needs to be continuously inquired

Step S27: and if the network state of the bearing network becomes congestion or overload, acquiring a second QoS request parameter.

Wherein the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter. For example, the bandwidth requested to be occupied in the first QoS request parameter is 2M, when the network status is not congested or overloaded, the maximum bandwidth that can be provided by the network resource of the bearer network is 3M, and after the network status is not congested or overloaded, the maximum bandwidth that can be provided by the network resource of the bearer network is reduced to 1.5M, and then the bandwidth requested to be occupied in the second QoS request parameter is 1.5M.

Step S28: and controlling the bearer network to reallocate the network resources for the application server according to the second QoS request parameter and the network resources of the bearer network.

After the network resources are reallocated, the quality of the network service of the application server is reduced, but the normal operation of the network service can still be ensured.

Step S29: and reporting the network state to the application server so that the application server sets a second QoS request parameter.

If the network state is already congested or overloaded when the first QoS request parameter is received, the network state is reported to the application server to remind the application server that network service failure may be caused if the application server still occupies network resources according to the first QoS request parameter.

Step S210: a second QoS request parameter is received from the application server.

Step S211: and controlling the bearer network to allocate network resources to the application server according to the second QoS request parameter and the network resources of the bearer network.

The difference between step S211 and step S28 is that the application server is already using the network resources of the bearer network when the network resources are allocated in step S28, and the application server is not yet using the network resources of the bearer network when the network resources are allocated in step S211.

Of course, the application server may also set other QoS request parameters, which are different from the bandwidth requested to be occupied by the second QoS request parameter but smaller than the bandwidth requested to be occupied by the first QoS request parameter.

Fig. 3 is a flowchart illustrating a third embodiment of the method for allocating network resources according to the present invention. The method for allocating the network resources comprises the following steps:

step S31: the network status of the bearer network is learned.

Step S32: a first QoS request parameter is received from an application server.

Step S33: and inquiring the network state of the bearer network at the current moment, and if the network state is not congested or overloaded, performing step S34.

Step S34: and setting a first QoS distribution parameter for the application server according to the first QoS request parameter and the network resource of the bearer network.

Step S35: and controlling the bearing network to allocate the network resources required by the first QoS allocation parameter to the application server.

Step S36: and judging whether the network state of the bearer network becomes congestion or overload, if so, performing step S371 or step S374, and if not, continuing to repeat step S36.

Step S371: and reporting the network state to the application server so that the application server sets a second QoS request parameter.

Wherein the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter.

Step S372: and judging whether the application server refuses to perform QoS renegotiation or not, if so, refusing to perform QoS renegotiation by the application server, and performing step S374, otherwise, allowing the application server to agree to perform QoS renegotiation, and performing step S373.

The application server can feed back a piece of information, and whether the application server refuses to carry out QoS renegotiation can be judged according to the information.

Step S373: it is determined whether the second QoS request parameter is received from the application server within a predetermined time, and if so, the second QoS request parameter is received within the predetermined time, and the step S38 is performed, and if not, the second QoS request parameter is not received within the predetermined time, and the step S374 is performed.

Step S374: and setting a second QoS request parameter according to the first QoS request parameter and the first QoS allocation parameter.

Step S38: and controlling the bearer network to reallocate the network resources for the application server according to the second QoS request parameter and the network resources of the bearer network.

After step S36, step S371 or step S374 may be performed, which illustrates that the process of acquiring the second QoS request parameter includes two ways.

In the following, an application scenario of the present embodiment will be exemplified:

it is assumed that the maximum bandwidth provided by the network resource is 3M when the network status of the bearer network is not congested or overloaded, and the maximum bandwidth provided by the network resource is 1.5M when the network status is congested or overloaded. The network service of the application server is video sharing, and the shared video has two formats. One is a standard definition format, the resolution of which is below 720p, 720p means that the vertical resolution of the video is 720 lines and progressive; the other is a high definition format, with a resolution above 720 p. The application server preferentially selects a high-definition format to share the video, the high-definition format is configured with a first QoS request parameter, the bandwidth occupied by the first QoS request parameter request is 2M, and the bandwidth occupied by the standard-definition format is 1M.

On one hand, when the first QoS request parameter is received, if the network state is not congested or overloaded, the first QoS allocation parameter is set according to the first QoS request parameter and the network resources of the bearer network, and since the bandwidth of the network resources of the bearer network is greater than 2M and is 3M at the maximum, the bandwidth occupied by the first QoS allocation parameter may be 3M at the maximum, and it is assumed that the bandwidth required to be occupied in the set first QoS allocation parameter is 3M. Then 3M bandwidth will be allocated for the application server when allocating network resources for the application server.

After the 3M bandwidth is allocated, the network status becomes congested or overloaded, and if the application server still selects a high-definition format to share the video, the video is likely to be unsmooth or the video loading fails. Therefore, the video needs to be shared by changing the format of the standard definition.

The second QoS request parameter may be determined by the user server via QoS renegotiation. If the application server is in a sharing fluency consideration to decide to perform QoS renegotiation, the application server selects the standard definition format to configure the second QoS request parameter. Therefore, when the bearer network is controlled to reallocate the network resources for the application server according to the second QoS request parameter and the network resources of the bearer network, the maximum bandwidth of 1.5M can be allocated.

If the application server refuses to perform QoS renegotiation or does not receive the second QoS request parameter within a preset time, the second QoS request parameter is set for the application server according to the first QoS request parameter and the first QoS allocation parameter, as mentioned above, the bandwidth required by the first QoS request parameter is 2M, the bandwidth required by the first QoS allocation parameter is 3M, and the bandwidth of the second QoS request parameter is set to be less than 2M, and is assumed to be 1M.

Of course, the application server may not be asked whether to perform QoS renegotiation, but the second QoS request parameter may be set for the application server directly according to the first QoS request parameter and the first QoS allocation parameter.

At this time, the maximum bandwidth of the network resource of the bearer network becomes 1.5M, so that the bearer network needs to be controlled to reallocate the network resource to the application server according to the second QoS request parameter and the network resource of the bearer network, so as to ensure smooth video sharing. When network resources are allocated, 1.5M bandwidth can be allocated to the application server at most.

On the other hand, if the network status is already congested or overloaded when the first QoS request parameter is received, the network status is reported to the application server, so that the application server sets a second QoS request parameter, assuming that the bandwidth requested by the second QoS request parameter is equal to the bandwidth required by the standard definition format. It is desirable for the application server to share videos in a high definition format, but if high definition videos are still used, the videos may not be smooth or the videos may fail to be loaded. Even in this case, the application server needs to decide whether to perform QoS renegotiation, because the persistence of adopting the high-definition format may wait for the network status to recover to idle or normal, although the video is not smooth or the video loading fails, so as to ensure the video effect.

In the method for allocating network resources of this embodiment, after allocating network resources according to the first QoS request parameter and the network resources, if the network status becomes congested or overloaded, the second QoS request parameter is obtained, and the network resources are reallocated according to the second QoS request parameter and the network resources, where the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter, so as to achieve the purpose of reducing the required network resources when the bearer network is congested or overloaded, reduce the influence on other application servers, maximally utilize the network resources, effectively manage the bearer network, and ensure the network resources are managed healthily,

fig. 4 is a flowchart illustrating a fourth embodiment of the method for allocating network resources according to the present invention. The method for allocating the network resources comprises the following steps:

step S41: and setting a first QoS request parameter, and sending the first QoS request parameter to a QoS management network element, so that the QoS management network element controls the bearer network to allocate network resources according to the first QoS request parameter and the network resources of the bearer network.

The bearer network is at the bottom layer, and defines the physical network interconnection method and the convention of using network resources. When network traffic needs to be carried using network resources of the carrier network, a requirement of the network resources is determined by the first QoS request parameter. For example, the bandwidth occupied by the request in the first QoS request parameter is 2M.

Step S42: and receiving the network state of the bearer network reported by the QoS management network element, wherein the network state is congestion or overload.

The QoS management network element can determine the network state of the bearer network by monitoring at least one of the modes of the storage space of the output port of the network node in the bearer network, the channel capacity of a link, the sending rate of an information source, the queuing length of a data packet and the like; or the QoS management network element receives the network state reported by the bearer network.

Step S43: and determining whether to approve QoS renegotiation according to a preset strategy. If so, the QoS renegotiation is granted, and the process proceeds to step S44, otherwise, the QoS renegotiation is rejected, and the process proceeds to step S45.

Step S44: and setting a second QoS request parameter, and sending the second QoS parameter to a QoS management network element, so that the QoS management network element controls the bearer network to allocate network resources according to the second QoS request parameter and the network resources of the bearer network, wherein the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter.

Wherein, if the QoS renegotiation is agreed, the first QoS request parameter is reset to obtain the second QoS request parameter,

step S45: and sending a rejection instruction to the QoS management network element so that the QoS management network element sets the second QoS request parameter.

Wherein, if the QoS renegotiation is refused, the QoS management network element sets a second QoS request parameter by itself,

in the method for allocating network resources of this embodiment, after sending the first QoS request parameter to the QoS management network element, if the network status of the bearer network is congestion or overload, the second QoS request parameter may be sent to the QoS management network element or the QoS management network element may set the second QoS request parameter by itself, and the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter, so as to achieve the purpose of reducing the required network resources when the bearer network is congested or overloaded, reduce the impact on other application servers, and ensure the network resource management to be performed healthily,

referring to fig. 5, it is a schematic structural diagram of a first embodiment of the QoS management network element of the present invention. The QoS management network element 51 comprises a monitoring module 511, an application module 512 and an allocation module 513. The QoS management network element 51 is connected to an application server 52 and a bearer network 53.

The monitoring module 511 is used to know the network status of the bearer network 53. The monitoring module 511 may monitor the network status by analyzing QoS data of the bearer network 53, where the QoS data includes, but is not limited to, storage space of an output port of a network node in the bearer network 53, channel capacity of a link, transmission rate of a source, queue length of a packet, and the like; alternatively, the monitoring module 511 receives the network status reported by the bearer network 53. Bearer network 53 is at the bottom level and defines the method of physical network interconnection and the conventions for using network resources.

The application module 512 is configured to receive the first QoS request parameter from the application server 52, query the network status of the bearer network 53 at the current time known by the monitoring module 511, and send the first QoS request parameter to the allocating module 513 when the network status at the current time is not congested or overloaded. The application server 52, in order to ensure that its network traffic is proceeding properly, will make a demand on the network resources, which is expressed by the first QoS request parameter. For example, the bandwidth occupied by the request in the first QoS request parameter is 2M. The network status is divided into two types, one is congestion or overload and the other is idle or normal. When the network status is congested or overloaded, the bearer network 53 can still provide network resources, but the network performance will decrease, and if the network status continues to remain congested or overloaded, the network performance of the bearer network 53 will decrease dramatically.

The allocating module 513 is configured to receive the first QoS request parameter from the application module 512, and control the bearer network 53 to allocate the network resource to the application server 52 according to the first QoS request parameter and the network resource of the bearer network 53. The allocation of network resources is subject to the network resources that can be allocated by the bearer network 53. For example, as long as the maximum bandwidth that can be provided by the network resources of the bearer network 53 is greater than 2M, the bearer network 53 may be controlled to allocate 2M bandwidth or a bandwidth greater than 2M to the application server 52.

The application module 512 is further configured to obtain a second QoS request parameter when the network status of the bearer network 53 becomes congested or overloaded after the allocation module 513 allocates the network resource to the application server 52, and send the second QoS request parameter to the allocation module 513. After the network resources are allocated, the network traffic of the application server 52 is in a running state. As mentioned above, the network service can operate normally while occupying 2M bandwidth. However, if the bandwidth that can be allocated by the bearer network 53 drops during a sudden change of network state to congestion or overload, the network traffic may fail due to the limitation of the bandwidth. Therefore, after allocating the network resources, it is still necessary to continue querying the network status of the bearer network 53.

The allocating module 513 is further configured to receive the second QoS request parameter from the application module 512, and control the bearer network 53 to reallocate the network resources for the application server 52 according to the second QoS request parameter and the network resources of the bearer network 53, where the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter. The bandwidth occupied by the request in the second QoS request parameter may be less than 2M, such as 1M. The reallocation of network resources by the application server 52 according to the configuration of the second QoS request parameter may reduce the quality of network traffic by the application server 52, but may ensure that network traffic does not fail.

Further, if the network status is congested or overloaded at the current time when the first QoS request parameter is received from the application server 52, the application module 512 is further configured to report the network status to the application server 52, so that the application server 52 sets the second QoS request parameter. And receives the second QoS request parameter from the application server 52 and sends the second QoS request parameter to the allocating module 513.

The allocating module 513 is further configured to receive the second QoS request parameter from the application module 512, and control the bearer network 53 to allocate the network resource to the application server 52 according to the second QoS request parameter and the network resource of the bearer network 53. The allocation process is similar to the above-described reallocation process and is not described in detail here.

Fig. 6 is a schematic structural diagram of a QoS management network element according to a second embodiment of the present invention. The QoS managing network element 61 comprises a monitoring module 611, an application module 612 and an allocating module 613. The QoS management network element 61 is connected to an application server 62 and a bearer network 63. The monitoring module 611, the application module 612 and the allocating module 613 of the present embodiment have the same technical features as the monitoring module 511, the application module 512 and the allocating module 513 of the previous embodiment, except that the application module 612 includes a receiving unit 601, an inquiring unit 602, a reporting unit 603 and a parameter resetting unit 604. The allocation module 613 comprises a parameter allocation unit 605 and an allocation control unit 606.

The parameter allocating unit 605 is configured to receive the first QoS request parameter from the application module 612, set the first QoS allocation parameter for the application server 62 according to the first QoS request parameter and the network resource of the carrier network 63, and send the first QoS allocation parameter to the allocation control unit 606, where the network resource required by the first QoS allocation parameter is not more than the network resource that can be allocated by the carrier network 63. In many cases, the network resources allocated by the application server 62 are not network resources required by the first QoS request parameter, but are instead associated with the bearer network 63. For example, the network service of the application server 62 is video sharing, and the shared video is divided into a standard definition format and a high definition format, where the resolution of the standard definition format is below 720p and the resolution of the high definition format is above 720 p. The application server 62 preferentially selects a high definition format, the high definition format configures a first QoS request parameter, a bandwidth occupied by the first QoS request parameter request is 2M, and a bandwidth occupied by the standard definition format is 1M. And the maximum bandwidth provided by the network resources when the network status of the bearer network 63 is idle or normal is 3M. The bandwidth that can be occupied by the set first QoS allocation parameter is at least 2M and at most not more than 3M, which is assumed to be 3M.

The allocation control unit 606 is configured to receive the first QoS allocation parameter from the parameter allocation unit 605, and control the bearer network 63 to allocate the network resource required by the first QoS allocation parameter to the application server 62. Allocation control unit 606 secures the bandwidth required by application server 62 to be able to allocate to the first QoS allocation parameter.

The receiving unit 601 is configured to receive a first QoS request parameter from the application server 62.

The querying unit 602 is configured to query the network state of the bearer network 63 at the current time, which is obtained by the monitoring module 611, when the receiving unit 601 receives the first QoS request parameter, and query the network state of the bearer network 63 after the allocating module 613 allocates the network resource to the application server 62.

The reporting unit 603 is configured to report the network state to the application server 62 when the network state of the bearer network 63 becomes congested or overloaded after the allocation module 613 allocates the network resource to the application server 62, so that the application server 62 sets the second QoS request parameter. At this time, the receiving unit 601 is also configured to receive the second QoS request parameter from the application server 62. When the network state becomes congested or overloaded, the maximum bandwidth provided by the idle network resources is 1.5M. When the application server 62 sets the second QoS request parameter by itself, the bandwidth occupied by the second QoS request parameter request is 1M.

The parameter resetting unit 604 is configured to set the second QoS request parameter according to the first QoS request parameter and the first QoS allocation parameter when it is determined that the receiving unit 601 does not receive the second QoS request parameter within the predetermined time or the application server 62 rejects the QoS renegotiation. Wherein, the bandwidth required by the first QoS request parameter is 2M, and the bandwidth required by the first QoS allocation parameter is 3M, then the network resource required by the set second QoS request parameter is not more than the network resource required by the first QoS request parameter, assuming that the bandwidth thereof is 1.5M.

After the receiving unit 601 receives or the parameter resetting unit 604 sets the second QoS request parameter, the second QoS request parameter is sent to the parameter allocating unit 605, and the parameter allocating unit 605 is further configured to set a second QoS allocation parameter for the application server 62 according to the second QoS request parameter and the network resource of the bearer network 63, and send the second QoS allocation parameter to the allocation controlling unit 606. Wherein the network resources required by the second QoS allocation parameter are no more than the network resources required by the second QoS request parameter. The bandwidth required by the second QoS request parameter is 1.5M, and the maximum bandwidth provided by the idle network resources is 1.5M, then the bandwidth required by the second QoS allocation parameter does not exceed 1.5M, which is assumed to be 1.5M,

in more embodiments, the application module 612 includes only the receiving unit 601, the querying unit 602, and the parameter resetting unit 604, and does not include the reporting unit 603, specifically:

The querying unit 602 is configured to query the network status of the bearer network 63 at the current time when the receiving unit 601 receives the first QoS request parameter, and query the network status of the bearer network 63 after the allocating module 613 allocates the network resource to the application server 62.

The parameter resetting unit 604 is configured to set the second QoS request parameter according to the first QoS request parameter and the first QoS allocation parameter when the network status of the bearer network 63 becomes congested or overloaded after the allocation module 613 allocates the network resources to the application server 62.

That is, when the network status becomes congested or overloaded, the QoS management network element 61 does not perform QoS renegotiation with the application server 62, but directly sets the second QoS request parameter, so that the processing speed of the QoS management network element 61 can be increased, which is beneficial to standardized management.

Fig. 7 is a schematic structural diagram of an application server according to an embodiment of the present invention. The application server 71 comprises a parameter setting module 711, a transceiving module 712 and a determining module 713. The application server 71 is connected to a QoS management network element 72, and the QoS management network element 72 is connected to a bearer network 73.

The parameter setting module 711 is configured to set the first QoS request parameter and send the first QoS request parameter to the transceiving module 712. The carrier network 73 is at the bottom and defines the method of physical network interconnection and the conventions for using network resources. The application server 71 determines the need for network resources by means of the first QoS request parameter when it needs to use the network resources of the bearer network 73 to carry network traffic. For example, the bandwidth occupied by the request in the first QoS request parameter is 2M.

The transceiver module 712 is configured to receive the first QoS request parameter from the parameter setting module 711, and send the first QoS request parameter to the QoS management network element 72, so that the QoS management network element 72 controls the bearer network 73 to allocate network resources according to the first QoS request parameter and the network resources of the bearer network 73; and is configured to receive the network status of the bearer network 73 reported by the QoS management network element 72, and send the network status of the bearer network 73 to the determining module 713, where the network status is congestion or overload. The QoS management network element 72 may determine the network status of the bearer network 73 by monitoring at least one of a storage space of an output port of a network node in the bearer network 73, a channel capacity of a link, a transmission rate of a source, a queuing length of a packet, and the like.

The determining module 713 is configured to receive the network status of the bearer network 73 from the transceiving module 712, and determine whether to approve QoS renegotiation according to a preset policy.

The parameter setting module 711 is further configured to set a second QoS request parameter when the determining module 713 agrees to perform QoS renegotiation, and send the second QoS parameter to the transceiving module 712, where network resources required by the second QoS request parameter are less than network resources required by the first QoS request parameter.

The transceiving module 712 is further configured to receive the second QoS parameter from the parameter setting module 711 and send the second QoS parameter to the QoS managing network element 72, so that the QoS managing network element 72 controls the bearer network 73 to allocate the network resource according to the second QoS request parameter and the network resource of the bearer network 73.

In this embodiment, the determining module 713 is further configured to generate a rejection instruction when determining that the QoS renegotiation is rejected, and send the rejection instruction to the transceiving module 712. The transceiving module 712 is further configured to receive a reject instruction from the determining module 713, and send the reject instruction to the QoS managing network element 72, so that the QoS managing network element 72 sets the second QoS request parameter.

The QoS management Network element includes a processor (processor) 81, a receiver (receiver) 82, a transmitter (emitter) 83, a Random Access Memory (RAM) 84, a Read Only Memory (ROM) 85, a bus 86, and a Network Interface Unit (Network Interface Unit) 87. The processor 81 is coupled to the receiver 82, the transmitter 83, the random access memory 84, the read only memory 85 and the network interface unit 87 through the bus 86. The receiver 82 and the transmitter 83 are connected to an application server (not shown) and a carrier network (not shown) through a network interface unit 87. When the QoS management network element needs to be operated, the QoS management network element is booted to enter a normal operation state by booting a Basic Input Output System (BIOS) fixed in the rom 85 or a boot loader boot system in the embedded system. After the QoS management network element enters the normal operation state, Application Programs (Application Programs) and an Operating System (OS) are executed in the random access memory 84 so that:

the receiver 82 receives the first QoS request parameter from the application server and transmits the first QoS request parameter to the processor 81.

The processor 81 learns the network status of the bearer network, and upon receiving the first QoS request parameter from the receiver 82, queries the network status of the bearer network at the current time, and when it is found that the network status at the current time is not congested or overloaded, controls the bearer network to allocate network resources to the application server according to the first QoS request parameter and the network resources of the bearer network, and when it is found that the network status of the bearer network after the network resources are allocated to the application server becomes congested or overloaded, obtains the second QoS request parameter, and controls the bearer network to reallocate network resources to the application server according to the second QoS request parameter and the network resources of the bearer network, wherein the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter.

Further, the processor 81 transmits the network status to the transmitter 83 when it is inquired that the network status is congested or overloaded at the present time.

The transmitter 83 is configured to receive the network status from the processor 81 and report the network status to the application server, so that the application server sets the second QoS request parameter.

The receiver 82 is configured to receive the second QoS request parameter from the application server and send the second QoS request parameter to the processor 81.

The processor 81 is further configured to receive a second QoS request parameter from the receiver, and control the bearer network to allocate network resources to the application server according to the second QoS request parameter and the network resources of the bearer network.

In this embodiment, the manner of acquiring the second QoS request parameter by the processor 81 may be: the sender 83 reports the network status to the application server to enable the application server to set the second QoS request parameter. The receiver 82 receives the second QoS request parameter from the application server and sends the second QoS request parameter to the processor 81.

In other embodiments, the processor 81 obtains the second QoS request parameter by: the processor 81 sets a first QoS allocation parameter for the application server according to the first QoS request parameter and network resources of the bearer network, wherein the network resources required by the first QoS allocation parameter are not more than idle network resources of the bearer network; and controlling the bearing network to allocate the network resources required by the first QoS allocation parameter to the application server. The processor 81 may obtain the second QoS request parameter by: and setting a second QoS request parameter according to the first QoS request parameter and the first QoS allocation parameter.

The specific operation process of the processor 81 may refer to the network resource allocation method and the QoS management network element of the foregoing embodiments, and will not be described in detail here.

Fig. 9 is a schematic structural diagram of another embodiment of the application server of the present invention. The application server includes a processor (processor) 91, a receiver (receiver) 92, a transmitter (emitter) 93, a Random Access Memory (RAM) 94, a Read Only Memory (ROM) 95, a bus 96, and a Network Interface Unit (Network Interface Unit) 97. The processor 91 is coupled to the receiver 92, the transmitter 93, the random access memory 94, the read only memory 95 and the network interface unit 97 through the bus 96. The receiver 92 and the transmitter 93 are connected to a QoS management network element (not shown) which is in turn connected to a bearer network (not shown) through a network interface unit 97. When the application server needs to be run, the application server is booted to enter a normal running state by starting a Basic Input Output System (BIOS) which is solidified in the rom 95 or a boot loader boot system in the embedded system. After the Application server enters the normal operation state, Application Programs (Application Programs) and an Operating System (OS) are executed in the random access memory 94 so that:

the processor 91 sets the first QoS request parameter and transmits the first QoS request parameter to the transmitter 93.

The transmitter 93 receives the first QoS request parameter from the processor 91 and transmits the first QoS request parameter to the QoS managing network element, so that the QoS managing network element controls the bearer network to allocate network resources according to the first QoS request parameter and the network resources of the bearer network.

The receiver 92 receives the network status of the bearer network reported by the QoS management network element, and sends the network status of the bearer network to the processor 91. Wherein the network status is congestion or overload.

The processor 91 is configured to receive a network status of the bearer network from the receiver 92, determine whether to approve QoS renegotiation according to a preset policy, set a second QoS request parameter when it is determined that the QoS renegotiation is approved, and transmit the second QoS parameter to the transmitter 93. Wherein the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter.

The transmitter 93 also receives the second QoS parameter from the processor 91 and transmits the second QoS parameter to the QoS managing network element so that the QoS managing network element controls the bearer network to allocate network resources according to the second QoS request parameter and the network resources of the bearer network.

The specific operation process of the processor 91 may refer to the network resource allocation method and the application server of the foregoing embodiments, and will not be described in detail here.

In the above manner, according to the method for allocating network resources of the present invention, when receiving a first QoS request parameter set by an application server, a QoS management network element and the application server first query a network state of a bearer network, if the network state is not congested or overloaded, allocate network resources of the bearer network according to the first QoS request parameter, and continue querying the network state after allocating the network resources, acquire a second QoS request parameter as long as the network state becomes congested or overloaded, and reallocate the network resources according to the second QoS request parameter, and if the network state is already congested or overloaded when receiving the first QoS request parameter, still acquire the second QoS request parameter, since the network resources required by the second QoS request parameter are less than the network resources required by the first QoS request parameter, when the bearer network is congested or overloaded, the method has the advantages of reducing the required network resources, maximally utilizing the network resources, reducing the influence on other application servers and ensuring the healthy management of the network resources.
