Detailed Description
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 some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, an embodiment of the present invention provides a method for network access, where an execution subject of the method is a virtual CP, and the method includes the following specific steps:
step 201: receiving a first message sent by an access UP;
in the embodiment of the invention, all UP is reclassified, and the UP accessed by the user is the access UP. A first message indicating a user request to access the network, the first message including a first hardware session utilization for the access UP, wherein the first hardware session utilization for the access UP is identified by an extended TAG field. The hardware session utilization rate is equal to the ratio of the number of the processed sessions of the hardware to the maximum number of the processed sessions of the hardware, and the resource occupation condition on the access UP can be known through the hardware session rate.
The embodiment of the invention is based on the RFC2516 protocol to expand the definition of the TAG field, optionally, the expanded TAG field is 0x0109 AC-use, and the expanded TAG is used for identifying the utilization rate of the hardware session.
It should be noted that the TAG in the first message is used to identify the hardware session utilization rate of the access UP, and for clarity of description, the hardware session utilization rate of the access UP is referred to as a first hardware session utilization rate.
Step 202: determining a processing UP corresponding to the access UP;
in the embodiment of the invention, the processing UP and the access UP are not the same UP, when the resources of the access UP are insufficient, the virtual CP determines a processing UP for the access UP according to the information contained in the first message, and dispatches the service flow which cannot be processed on the access UP to the processing UP for processing, wherein the processing UP has a virtual type and an entity type.
Step 203: respectively sending a first configuration message to an access UP and a processing UP;
in the embodiment of the present invention, the first configuration message is used to instruct the access UP and the processing UP to establish a tunnel between the access UP and the processing UP, through which the traffic flow of a user accessed from the access UP can be scheduled to be processed on the processing UP.
In the embodiment of the invention, a virtual CP determines a processing UP corresponding to an access UP according to a first message which is sent by the access UP and used for indicating that a user requests to access a network, and sends a first configuration message to the access UP and the processing UP respectively to indicate the access UP and the processing UP to establish a tunnel between the access UP and the processing UP. Thus, when the resources of the access UP are insufficient, the user traffic is scheduled to the processing UP for processing by establishing the tunnel between the access UP and the processing UP, so that the utilization of the resources is balanced.
In the current transfer control separation virtual BRAS system, when the user's traffic needs to be processed by virtual UP, all the entity UPs needs to be statically configured with corresponding policy so as to send the traffic to the virtual UP. If the service processed by the virtual UP changes, all the entity UPs need to be reconfigured once, resulting in a large configuration and maintenance workload.
In order to solve the above problem, the virtual CP according to the embodiments of the present invention determines the processing UP corresponding to the access UP in different manners according to different types of processing CPs. Specifically, referring to fig. 3, for step 202 in fig. 2, an embodiment of the present invention provides a method for determining a processing UP corresponding to an access UP, which includes the following specific steps:
step 2021: acquiring a service type from the VLAN;
in the embodiment of the present invention, the virtual CP may be determined according to the identifier of the service type in the VLAN, for example: VLAN1 represents a large-session small-flow service, VLAN2 represents a large-flow service, and the embodiment of the present invention does not limit the specific manner in which the virtual CP obtains the service type from the VLAN.
Step 2022: determining the type of the UP according to the service type, and then executing step 2023 or step 2024;
in the embodiment of the present invention, the types of UP include: the embodiment of the invention does not specifically limit the corresponding relationship between the service type and the type of the processing UP.
Step 2023: when the type of the processing UP is a virtual type, selecting a virtual user plane, and determining the virtual user plane as the processing UP;
step 2024: when the type of the processing UP is an entity type and the utilization rate of a first hardware session accessed to the UP is larger than a preset threshold value, selecting an entity UP with the lowest hardware session utilization rate from a plurality of other entity UP except the accessed UP, and determining the entity UP as the processing UP;
in the embodiment of the present invention, the virtual CP stores a preset threshold in advance, for example, 80%, and when the first hardware session rate of accessing UP exceeds the preset threshold, it indicates that the resources on the access are insufficient and the newly accessed service traffic cannot be processed. Therefore, the virtual CP selects an entity UP with the lowest hardware session utilization rate from the plurality of entity UPs except the access UP, determines the entity UP as a processing UP, schedules the newly accessed traffic onto the processing UP for processing, and fully utilizes resources on the UP.
It can be understood that, if the first hardware session rate of the access UP does not exceed the preset threshold value, which indicates that the resources on the access UP are still sufficient, the access UP itself processes the accessed traffic in the existing manner.
It should be noted that, along with the original service traffic processing on the access UP, the hardware session utilization of the access UP may decrease to be lower than the preset threshold, but the service traffic scheduled to process the UP is not called back until the session is completed.
In conjunction with the methods of fig. 2 and fig. 3, when resources on the access UP are insufficient, the virtual CP can automatically determine a corresponding processing UP for the access UP, where the type of the processing UP includes: a virtual type and an entity type; the virtual CP can also automatically configure the tunnel between the access UP and the processing UP, when the type of the processing UP is a virtual type, the service flow can be flexibly scheduled between the access UP and the processing UP through the tunnel, corresponding strategies do not need to be statically configured on all the entity UP, and the workload of configuration and maintenance is reduced.
Referring to fig. 4, an embodiment of the present invention provides another network access method, where an execution subject of the method is a virtual CP, and the method includes the following specific steps:
step 401: receiving a first message sent by an access UP;
step 402: determining a processing UP corresponding to the access UP;
step 403: respectively sending a first configuration message to an access UP and a processing UP;
the descriptions of step 401 to step 403 may refer to the descriptions of step 201 to step 203 in fig. 2, and are not repeated herein.
Step 404: receiving a second hardware session utilization rate of the processing UP sent by the processing UP;
in the embodiment of the present invention, after the UP completes the establishment of the tunnel to be accessed to the UP, the UP reports its own hardware session utilization rate to the virtual CP, and for clarity of description, the foregoing hardware session utilization rate is referred to as a second hardware session utilization rate.
And the processing UP reports the utilization rate of the second hardware session to the virtual CP after the tunnel establishment is finished, so that the virtual UP can acquire the utilization rate of the hardware session on each UP in real time, and the UP with the lowest hardware session utilization rate can be selected as the processing UP when the corresponding processing UP is selected for other access UPs subsequently.
Step 405: receiving a second message sent by the UP processing;
in the embodiment of the present invention, the second message indicates that the user requests to exit the network, and the second message includes a third hardware session utilization rate for processing UP, and the third hardware session utilization rate for processing UP is identified by an extended TAG field.
The embodiment of the invention is based on the RFC2516 protocol to expand the definition of the TAG field, optionally, the expanded TAG field is 0x0109 AC-use, and the expanded TAG is used for identifying the utilization rate of the hardware session.
It should be noted that the TAG in the second message is used to identify the hardware session utilization rate for processing UP, and for clarity of description, the hardware session utilization rate for processing UP is referred to as a third hardware session utilization rate.
Therefore, when each session is completed, the virtual CP can timely acquire the change of the hardware session utilization rate of each UP, and the subsequent determination of new processing UP is facilitated.
Step 406: when detecting that all the sessions in the tunnel are off-line, respectively sending a second configuration message to the access UP and the processing UP;
in the embodiment of the present invention, the virtual CP can directly monitor the offline condition of the session in the tunnel, when detecting that all sessions in the tunnel are offline, it indicates that resources on the access UP are sufficient, and the traffic flow scheduled to the processing UP is completely processed, the virtual CP sends a second configuration message to the access UP and the processing UP respectively, and the second configuration message is used for indicating the access UP and the processing UP to cancel the tunnel between the processing UP and the access UP.
In the embodiment of the invention, when the resources on the access UP are insufficient, the virtual CP can determine the corresponding processing UP for the access UP, establish a tunnel between the access UP and the processing UP and schedule the service flow which can not be processed by the access UP to the processing UP for processing; when the service flow processing is completed and all the sessions in the tunnel are offline, the virtual CP can indicate the access UP and the processing UP to cancel the tunnel, thereby realizing the flexible scheduling of the service flow, fully utilizing the UP resources and reducing the workload of configuration and maintenance.
