Embodiment 1
[0022] see figure 1 The method for bandwidth allocation provided by Embodiment 1 of the present invention includes the following steps:
[0023] S101. Identify the network application to which each data flow belongs in combination with the flow feature database.
[0024] Network applications usually use data packets of Transmission Control Protocol (Transmission Control Protocol, TCP) and User Datagram Protocol (User Datagram Protocol, UDP) protocol for communication, and such data packets must contain a five-tuple (five-tuple Group includes protocol type, source IP address, destination IP address, source port number and destination port number), and data packets containing the same five-tuple are regarded as one data flow. Wherein, two quintuples in which the source IP address and the destination IP address are exchanged are also regarded as the same quintuple.
[0025] In Embodiment 1 of the present invention, identifying the network application to which each data stream b...
Embodiment 2
[0094] see Figure 4 , the router provided in Embodiment 2 of the present invention includes: an identification module 11, a monitoring module 12, and an adjustment module, wherein,
[0095] The identification module 11 is used to identify the network application to which each data flow belongs in combination with the flow feature database, the flow feature database including the correspondence between the flow feature and the network application;
[0096] Network applications usually use TCP and UDP protocol data packets for communication, and such data packets must contain a quintuple (the quintuple includes protocol type, source IP address, destination IP address, source port number, and destination port number), and data packets containing the same quintuple are regarded as a data stream. Wherein, two quintuples in which the source IP address and the destination IP address are exchanged are also regarded as the same quintuple.

Abstract
The invention is suitable for the filed of communications, and provides a bandwidth allocation method and a router. The method comprises the following steps of: identifying the network application which each data stream belongs to in combination with a stream characteristic database which comprises the corresponding relationship between stream characteristics and the network applications; monitoring the current total network bandwidth and the current use bandwidth of each priority service, the priority services are different priority services obtained by dividing the data streams according to the features of the belonged network applications, each priority service comprising one or more data streams; adjusting the uplink bandwidth and the downlink bandwidth used by each priority service respectively according to the current total network bandwidth and the current use bandwidth of each priority service. According to the bandwidth allocation method and the router provided by the invention, because the uplink bandwidth and the downlink bandwidth used by each priority service are adjusted respectively according to the current total network bandwidth and the current use bandwidth of each priority service, the bandwidth can be intelligently and reasonably adjusted, and the Internet surfing experience of end users is good.
Description
technical field [0001] The invention belongs to the communication field, and in particular relates to a bandwidth allocation method and a router. Background technique [0002] A router is a device that itself has the function of accessing the Internet and can provide terminals with access functions. A terminal is a device that a user uses to connect to a router to access the Internet, including smartphones and PCs. [0003] Traditional home broadband networks basically have the problem of unequal uplink and downlink bandwidths. For example, the downlink bandwidth of 12MB / s is only the uplink bandwidth of 512KB / s. On the other hand, at present, many terminal applications are implemented based on peer-to-peer computing (Peer to Peer, P2P) network, that is, they not only download data, but also share the downloaded data with other terminal applications. Under such conditions, the uplink bandwidth is often occupied earlier, and the request sent by the terminal application may ...
