Referring to fig. 1, the present embodiment provides a packet delivery method based on composite priority control, which includes the following steps:
s100, receiving a bandwidth configuration request sent by one or more users at the current moment;
s200, ordering all users at the current moment according to a preset first priority, and/or ordering bandwidth configuration requests sent by each user according to a preset second priority;
s300, obtaining the bandwidth transmitted to the corresponding user by one or more network links in the historical moment according to the bandwidth configuration request sent by each user;

By means of the scheme, the corresponding data packets can be distributed to the interfaces of the users according to the priorities of the users and/or the priorities of the bandwidth configuration requests, waiting time of the users is shortened, and transmission efficiency of the data packets is improved.
Specifically, the data packet forwarding method provided by the embodiment of the invention is specifically executed by a data packet forwarding device through a network link, where the data packet forwarding device may be a network device such as a switch, a router, and the like. The packet forwarding device is typically deployed on a service gateway, such as a broadband remote access server (Broadband Remote Access Server, BRAS for short).
In an embodiment, if the bandwidth transmitted to the certain user by one or more network links at the historical moment cannot be obtained according to the bandwidth configuration request sent by the certain user at the current moment, an allowable burst bandwidth is directly allocated to the certain user, and a corresponding data packet is allocated to the interface of the certain user according to the allowable burst bandwidth. In this embodiment of the present application, if the bandwidth transmitted to the user by one or more network links at the historical moment cannot be obtained according to the bandwidth configuration request sent by the user at the current moment, this indicates that the user sends the bandwidth configuration request for the first time, in order to improve the use experience of the user, an allowable burst bandwidth may be provided, where the allowable burst bandwidth is greater than the subscription bandwidth of the user.
Typically, the subscription bandwidth of a subscriber is fixed, e.g. it may be 2Mbps (megabits per second), and the service provider allocates bandwidth to the subscriber according to the subscriber's subscription bandwidth. When the user has new service, the service provider allocates available bandwidth for the new service of the user according to the contracted bandwidth of the user and the occupied bandwidth of the user, so that the available bandwidth of the new service of the user is limited by the contracted bandwidth of the user and the occupied bandwidth of the user. When the new service of the user needs to access big data, the service initial buffering time is longer because the available bandwidth of the new service allocated to the user is limited. In the data packet forwarding method provided by the embodiment of the invention, a data packet forwarding device allocates an allowable burst bandwidth for a user in advance (wherein the allowable burst bandwidth is larger than the subscription bandwidth of the user) so as to allow the bandwidth occupied by the user in a preset time to reach the allowable burst bandwidth; after receiving a data packet, a data packet forwarding device queries a session information table according to session information in the data packet to determine whether the data packet is the first data packet of a first session of the user, wherein the session information table is used for recording session information of the user; if the data packet is judged to be the first data packet of the first session of the user, the data packet forwarding device indicates that the first session is a new session of the user, and the data packet forwarding device acquires a first available bandwidth allocated to the first session according to the allowable burst bandwidth of the user and the occupied bandwidth of the user; and the data packet forwarding device forwards the data packets of the first session according to the first available bandwidth in a preset time. Since the first available bandwidth is determined by the allowable burst bandwidth of the user and the occupied bandwidth of the user, the data packet traffic of the first session may burst into the first available bandwidth.
In an exemplary embodiment, the first priority includes: the subscription bandwidth of the user and the bandwidth subscription time limit of the user; the second priority includes: bandwidth configuration time, bandwidth configuration place, bandwidth configuration frequency, bandwidth configuration usage. The method further comprises the steps of calculating a first weight value of each user according to the first priority, and calculating a second weight value of each bandwidth configuration request according to the second priority; and calculating the bandwidth configuration weight of each user at the current moment according to the first weight value and the second weight value, and distributing corresponding data packets for the interfaces of each user at the current moment according to the bandwidth configuration weight.
Specifically, the available bandwidth of the user depends on factors such as a resource allocation policy and a subscription bandwidth of the user, and in this embodiment, the resource allocation policy is ordered according to the priority of the user and the priority of the user bandwidth configuration request, and is allocated before and after the ordering. In this embodiment of the present application, the first priority ranking manner or the user ranking manner may be set according to practical situations, for example, the priority of setting the bandwidth subscription time limit of the user is greater than the priority of the subscription bandwidth of the user. If the subscription bandwidth of the user A is 6Mbps, the subscription time limit is 2 years; the subscription bandwidth of the user B is 10Mbps, and the subscription time limit is 1 year. The subscription bandwidth weight values of the user A and the user B are calculated respectively, and the subscription bandwidth weight values are: subscription bandwidth weight value of user a = quench
/>
=0.375, subscription bandwidth weight value of user b=quite +.>
/>
=0.625; subscription bandwidth weight value of user a = quench->
/>
=0.67, subscription bandwidth weight value of user b=quite +.>
/>
=0.33; so the first weight value of user a is 0.67+0.375=1.045; the first weight value of user B is 0.625+0.33=0.955. Because the first weight value of the user a is greater than the first weight value of the user B, if the allocation is performed only according to the first priority of the user, the corresponding data packet is allocated to the interface of the user according to the bandwidth configuration request of the user a, and then the user B is performed. For example, the bandwidth required by the bandwidth configuration request of the user a at the current time is 5.5Mbps, and the bandwidth required by the bandwidth configuration request of the user B at the current time is 8Mbps, then the user a is satisfied first. Similarly, the second priority ordering manner or the bandwidth configuration request ordering manner may be set according to the actual situation, for example, the second priority ordering manner in the present application is: bandwidth allocation usage > bandwidth allocation place > bandwidth allocation frequency > bandwidth allocation time. The second weight value is calculated in the same way as the first weight value; and calculating the weight value corresponding to each priority item, then summing the weight values of all priority items of the same bandwidth configuration request to obtain a second weight value of each bandwidth configuration request, and then sequencing according to the second weight values. If the data packets are distributed according to the second priority, the data packets are directly distributed according to the sorting result of the second weight value. If the first weight value and the second weight value are carried out simultaneously, the first weight value and the second weight value are weighted and summed, the total weight value of each user is calculated, the total weight values are ordered, and the data package is distributed according to the ordering result.
The method comprises the steps of receiving a bandwidth configuration request sent by one or more users at the current moment; sequencing all users at the current moment according to a preset first priority, and/or sequencing bandwidth configuration requests sent by each user according to a preset second priority; acquiring the bandwidth transmitted to the corresponding user by one or more network links in the historical moment according to the bandwidth configuration request sent by each user; acquiring the bandwidth configuration request sent by the ordered user and/or the user and the bandwidth transmitted to the corresponding user by one or more network links at the historical moment; and calculating the bandwidth configuration weight of each user at the current moment, and distributing corresponding data packets for the interfaces of each user at the current moment according to the bandwidth configuration weight. The method can allocate the corresponding data packet to the interface of the user according to the priority of the user and/or the priority of the bandwidth configuration request, thereby reducing the waiting time of the user and accelerating the transmission efficiency of the data packet.
As shown in fig. 2, the present invention further provides a packet delivery system based on composite priority control, where the system includes:
a first obtaining module M10, configured to receive a bandwidth configuration request sent by one or more users at a current moment;
the ordering module M20 is configured to order all users at the current moment according to a preset first priority, and/or order bandwidth configuration requests sent by each user according to a preset second priority;
the second obtaining module M30 obtains the bandwidth transmitted to the corresponding user by one or more network links in the historical moment according to the bandwidth configuration request sent by each user;
the configuration module M40 acquires the ordered users and/or bandwidth configuration requests sent by the users and the bandwidths transmitted to the corresponding users by one or more network links at the historical moment; calculating bandwidth configuration weight of each user at the current moment, and distributing corresponding data packets for the interfaces of each user at the current moment according to the bandwidth configuration weight; wherein the data packets comprise data packets fragmented by one or more network links.
By means of the scheme, the corresponding data packets can be distributed to the interfaces of the users according to the priorities of the users and/or the priorities of the bandwidth configuration requests, waiting time of the users is shortened, and transmission efficiency of the data packets is improved.
Specifically, the data packet forwarding method provided by the embodiment of the invention is specifically executed by a data packet forwarding device through a network link, where the data packet forwarding device may be a network device such as a switch, a router, and the like. The packet forwarding device is typically deployed on a service gateway, such as a broadband remote access server (Broadband Remote Access Server, BRAS for short).
In an exemplary embodiment, if the second obtaining module M30 cannot obtain the bandwidth transmitted to the certain user by one or more network links at the historical moment according to the bandwidth configuration request sent by the certain user at the current moment, the configuration module M40 directly allocates an allowable burst bandwidth to the certain user, and allocates a corresponding data packet to the interface of the certain user according to the allowable burst bandwidth. In this embodiment of the present application, if the bandwidth transmitted to the user by one or more network links at the historical moment cannot be obtained according to the bandwidth configuration request sent by the user at the current moment, this indicates that the user sends the bandwidth configuration request for the first time, in order to improve the use experience of the user, an allowable burst bandwidth may be provided, where the allowable burst bandwidth is greater than the subscription bandwidth of the user.
Typically, the subscription bandwidth of a subscriber is fixed, e.g. it may be 2Mbps (megabits per second), and the service provider allocates bandwidth to the subscriber according to the subscriber's subscription bandwidth. When the user has new service, the service provider allocates available bandwidth for the new service of the user according to the contracted bandwidth of the user and the occupied bandwidth of the user, so that the available bandwidth of the new service of the user is limited by the contracted bandwidth of the user and the occupied bandwidth of the user. When the new service of the user needs to access big data, the service initial buffering time is longer because the available bandwidth of the new service allocated to the user is limited. In the data packet forwarding method provided by the embodiment of the invention, a data packet forwarding device allocates an allowable burst bandwidth for a user in advance (wherein the allowable burst bandwidth is larger than the subscription bandwidth of the user) so as to allow the bandwidth occupied by the user in a preset time to reach the allowable burst bandwidth; after receiving a data packet, a data packet forwarding device queries a session information table according to session information in the data packet to determine whether the data packet is the first data packet of a first session of the user, wherein the session information table is used for recording session information of the user; if the data packet is judged to be the first data packet of the first session of the user, the data packet forwarding device indicates that the first session is a new session of the user, and the data packet forwarding device acquires a first available bandwidth allocated to the first session according to the allowable burst bandwidth of the user and the occupied bandwidth of the user; and the data packet forwarding device forwards the data packets of the first session according to the first available bandwidth in a preset time. Since the first available bandwidth is determined by the allowable burst bandwidth of the user and the occupied bandwidth of the user, the data packet traffic of the first session may burst into the first available bandwidth.
In an exemplary embodiment, the first priority in the ranking module M20 includes: the subscription bandwidth of the user and the bandwidth subscription time limit of the user; the second priority in the ranking module M20 includes: bandwidth configuration time, bandwidth configuration place, bandwidth configuration frequency, bandwidth configuration usage. The configuration module M40 further includes calculating a first weight value of each user according to the first priority, and calculating a second weight value of each bandwidth configuration request according to the second priority; and calculating the bandwidth configuration weight of each user at the current moment according to the first weight value and the second weight value, and distributing corresponding data packets for the interfaces of each user at the current moment according to the bandwidth configuration weight.
Specifically, the available bandwidth of the user depends on factors such as a resource allocation policy and a subscription bandwidth of the user, and in this embodiment, the resource allocation policy is ordered according to the priority of the user and the priority of the user bandwidth configuration request, and is allocated before and after the ordering. In this embodiment of the present application, the first priority ranking manner or the user ranking manner may be set according to practical situations, for example, the priority of setting the bandwidth subscription time limit of the user is greater than the priority of the subscription bandwidth of the user. If the subscription bandwidth of the user A is 6Mbps, the subscription time limit is 2 years; the subscription bandwidth of the user B is 10Mbps, and the subscription time limit is 1 year. Calculating subscription bandwidths of user A and user B respectivelyThe weight values are as follows: subscription bandwidth weight value of user a = quench
/>
=0.375, subscription bandwidth weight value of user b=quite +.>
/>
=0.625; subscription bandwidth weight value of user a = quench->
/>
=0.67, subscription bandwidth weight value of user b=quite +.>
/>
=0.33; so the first weight value of user a is 0.67+0.375=1.045; the first weight value of user B is 0.625+0.33=0.955. Because the first weight value of the user a is greater than the first weight value of the user B, if the allocation is performed only according to the first priority of the user, the corresponding data packet is allocated to the interface of the user according to the bandwidth configuration request of the user a, and then the user B is performed. For example, the bandwidth required by the bandwidth configuration request of the user a at the current time is 5.5Mbps, and the bandwidth required by the bandwidth configuration request of the user B at the current time is 8Mbps, then the user a is satisfied first. Similarly, the second priority ordering manner or the bandwidth configuration request ordering manner may be set according to the actual situation, for example, the second priority ordering manner in the present application is: bandwidth allocation usage > bandwidth allocation place > bandwidth allocation frequency > bandwidth allocation time. The second weight value is calculated in the same way as the first weight value; calculating the weight value corresponding to each priority item, and then allocating to the same bandwidthAnd summing the weight values of all priority items of the request to obtain a second weight value of each bandwidth configuration request, and then sequencing according to the second weight value. If the data packets are distributed according to the second priority, the data packets are directly distributed according to the sorting result of the second weight value. If the first weight value and the second weight value are carried out simultaneously, the first weight value and the second weight value are weighted and summed, the total weight value of each user is calculated, the total weight values are ordered, and the data package is distributed according to the ordering result.
The system receives bandwidth configuration requests sent by one or more users at the current moment; sequencing all users at the current moment according to a preset first priority, and/or sequencing bandwidth configuration requests sent by each user according to a preset second priority; acquiring the bandwidth transmitted to the corresponding user by one or more network links in the historical moment according to the bandwidth configuration request sent by each user; acquiring the bandwidth configuration request sent by the ordered user and/or the user and the bandwidth transmitted to the corresponding user by one or more network links at the historical moment; and calculating the bandwidth configuration weight of each user at the current moment, and distributing corresponding data packets for the interfaces of each user at the current moment according to the bandwidth configuration weight. The system can distribute the corresponding data packets to the interfaces of the users according to the priorities of the users and/or the priorities of the bandwidth configuration requests, thereby reducing the waiting time of the users and accelerating the transmission efficiency of the data packets.
