Detailed Description

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the embodiment of the present application, the first user and the second user refer to users handling network services in a family unit. When an operator opens a network service for a home user, the geographic position of the home user is bound with a network account, and the network account of the user comprises a user name and a password. The user connects to the network by authenticating the username and password.

In the embodiment of the application, the reserved bandwidth refers to a bandwidth which is used by an operator to limit the maximum bandwidth used by a user and can ensure that the user traffic can still reach even when congestion occurs. For example, the reserved bandwidth of a user following 100BASE-TX is 10 megabits per second (Mbps), and the maximum transmission rate of the reserved bandwidth of the user is 10 Mbps.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. The first user 104 sends a request message for surfing the internet to the first network device through the second network device 102. After receiving the internet access request message of the first user 104, the first network device 101 sends an internet access confirmation message to the first user 104 through the second network device 102. The first user 104 connects to the network 106 through the second network device 102. The second user 105 sends a request message for surfing the internet to the first network device through the third network device 103. After receiving the internet access request message of the second user 105, the first network device 101 sends an internet access confirmation message to the second user 105 through the third network 103. The second user 105 connects to the network 106 through the third network device 103.

The above scheme has the following problems: the first user and the second user are in different geographical locations, so that the operator cannot uniformly manage the traffic of the first user and the traffic of the second user. For example, when the first user 104 and the second user 105 belong to the same family user and surf the internet through the same network account, the operator cannot combine and calculate the traffic of the first user 104 and the second user 105 to be charged uniformly, and cannot share the bandwidth of the first user 104 and the second user 105.

In order to solve the above problem, as shown in fig. 1, in an application scenario provided in the embodiment of the present application, a first user 104 sends a first username to a first network device 101 through a second network device 102. The second user 105 sends a second username to the first network device 101 through the third network device 103. If the first network device 101 determines that the first user name is the same as the second user name, the first network device 101 manages traffic of the first user 104 and the second user 105 in a unified manner. The unified management of the traffic of the users in different geographic positions by the operator is realized.

For example, the first network device 101 may be a network function virtualization device, such as a virtual network engine device. The second network device 102 and the third network device 103 may be forwarding devices, such as routers, defined in the OPENFLOW protocol. The first user 104 sends a first username corresponding to the first user to the second network device 102. The second user 105 sends a second username corresponding to the second user 104 to the third network device 103. After the virtual network engine device 101 receives the first user name and the second user name, if the first user name is the same as the second user name, the virtual network engine device 101 manages the traffic of the first user and the traffic of the second user in a unified manner.

Fig. 2 shows a flow chart of a method for traffic management according to an embodiment of the present application. For example, the method may be applied to the application scenario shown in fig. 1. 101 in fig. 1 may be a first network device involved in the method shown in fig. 2, 102 in fig. 1 may be a second network device involved in the method shown in fig. 2, and 103 in fig. 1 may be a third network device involved in the method shown in fig. 2. The method shown in fig. 2 comprises the following steps.

S201, the first network device receives a first user name sent by a second network device, the first user name corresponds to a first user, and the first user is connected with the Internet through the second network device.

The first user sends the first user name corresponding to the first user to the second network equipment, and the first user realizes network connection through the access protocol processing and user management of the second network equipment. The first network equipment receives the first user name sent by the second network equipment.

For example, a first network device establishes a first OPENFLOW control channel with the second network device, and the first network device receives a first username sent by the second network device through the first OPENFLOW channel.

For example, the second network device may send a username for the first user to PPPoE dial to the first network device. The first network equipment receives a user name of PPPoE dialing of the first user sent by the second network user.

S202, the first network equipment receives a second user name sent by third network equipment, the second user name corresponds to a second user, and the second user is connected with the Internet through the third network equipment.

And the second user sends a second user name corresponding to the second user to the third network equipment, and the second user realizes network connection through the access protocol processing and user management of the third network equipment. And the first network equipment receives the second user name sent by the third network equipment.

For example, the first network device establishes a second OPENFLOW control channel with the third network device, and the first network device receives the second username sent by the third network device through the second OPENFLOW channel.

For example, the second network device may send a username for the first user to PPPoE dial to the first network device. The first network equipment receives a user name of PPPoE dialing of the first user sent by a third network user.

S203, when the first user name is the same as the second user name, the first network device performs unified traffic management on the first user and the second user.

Specifically, if the first network device determines that the user names of the first user and the second user are the same, the first network device performs unified management on the traffic of the first user and the traffic of the second user.

For example, a first network device obtains a first username of a first user of a PPPoE dial-up network. The first network equipment obtains a second user name of a second user PPPoE dial-up networking. And if the first user name is the same as the second user name, the first network equipment uniformly manages the flow of the first user and the flow of the second user.

According to the scheme, the first network device receives the first user name sent by the second network device and the second user name sent by the third network device. And if the user names are the same, uniformly managing the traffic of the first user and the second user. Therefore, unified flow management can be performed on the home users in different geographic positions, the management cost of an operator is reduced, and convenience is provided for the users.

Optionally, the performing, by the first network device, unified traffic management on the first user and the second user includes:

the first network device receives a first traffic statistic value sent by the second network device, wherein the first traffic statistic value is a user traffic statistic value of the first user on the second network device.

And the first network equipment receives a second traffic statistic value sent by the third network equipment, wherein the second traffic statistic value is a user traffic statistic value of the second user on the third network equipment.

And the first network equipment sets the first user and the second user to belong to the same user group, and sets the user group name as the first user name or the second user.

Specifically, the second network device sends the internet traffic statistics of the first user to the first network device, and the third network device also sends the internet traffic statistics of the second user to the first network device. The first network equipment sets a first user and a second user with the same user name as a same user group, and sets the group name of the user group as the first user name or the second user name. After receiving the first user internet traffic statistic sent by the second network device and the second user internet traffic statistic sent by the third network device, the first network device adds the two traffic statistics to obtain a third traffic statistic. And the first network equipment sends the obtained third flow statistic and the group name of the user group to a charging server, so that the charging server performs unified charging on the third flow statistic according to the group name of the user group, and the charging of the user group by the charging server comprises the internet surfing expense of the first user and the internet surfing expense of the second user. The unified charging of the traffic of the first user and the traffic of the second user in different geographic positions by an operator is realized, and the management cost of the operator is reduced.

And if the first user name is the same as the second user name, merging and calculating the flow of the first user and the second user, uniformly charging, and reducing the management cost of an operator.

and the first network equipment receives a first reserved bandwidth and a first real-time bandwidth which are sent by the second network equipment, wherein the first reserved bandwidth is a reserved bandwidth of the first user on the second network equipment. The first real-time bandwidth is a real-time bandwidth of the first user on the second network device.

And the first network device receives a second reserved bandwidth and a second real-time bandwidth which are sent by the third network device, wherein the second reserved bandwidth is a reserved bandwidth of the second user on the third network device, and the second real-time bandwidth is a real-time bandwidth of the second user on the third network device.

And the first network device sends the third reserved bandwidth value to the second network device, so as to instruct the second network device to receive the traffic of the first user according to the third reserved bandwidth value.

And the first network device sends the fourth reserved bandwidth value to the third network device, so as to instruct the third network device to receive the traffic of the second user according to the fourth reserved bandwidth value.

Specifically, the first network device receives a first real-time bandwidth value and a first reserved bandwidth value sent by the second network device, and receives a second real-time bandwidth value and a first reserved bandwidth value sent by the third network device. When the first real-time bandwidth of the first user exceeds the set first threshold, it indicates that the second network device may be in a congestion state, and when the second real-time bandwidth of the second user is lower than the second threshold of the device, it indicates that the third network device may be in an idle state, at this time, the first network device sends a part of reserved bandwidth of the second user to the second device, so as to guide the second network device to receive the traffic of the first user according to the increased reserved bandwidth, so that the first user may share the second reserved bandwidth of the second user.

For example, the real-time bandwidth of the first user received by the first network device and sent by the second network device is 11Mbps, and the reserved bandwidth of the first user received by the first network device and sent by the second network device is 15 Mbps. The second network device also receives a first threshold value sent by the second network device, wherein the first threshold value is 9 Mbps. The real-time bandwidth 11Mbps of the first user already exceeds the set first threshold of 9Mbps, which may cause congestion in the traffic of the first user. The real-time bandwidth of the second user, which is received by the first network device and sent by the third network device, is 1Mbps, and the reserved bandwidth of the second user, which is received by the first network device and sent by the third network device, is 8 Mbps. The second network device also receives a second threshold value sent by the third network device, wherein the second threshold value is 5Mbps, and the second real-time bandwidth 1Mbps of the second user is lower than the second threshold value of the device by 5Mbps, indicating that the third network device is in an idle state. The first network device may allocate 4Mbps of the reserved bandwidth 8Mbps of the second user to the second network device, so as to instruct the second network device to receive 11Mbps of traffic of the first user according to the increased reserved bandwidth 19Mbps, so that the first user and the second user may share the reserved bandwidth.

Under the condition that the first user name is the same as the second user name, if the real-time bandwidth of the first user is smaller than a set first threshold value and the real-time bandwidth of the second user is larger than a set second threshold value, the first network device can share part of the reserved bandwidth of the first user with the second user for use, and user experience is improved.
