Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1a is a schematic diagram of a flow control method according to an embodiment of the present application, where the embodiment of the present application is applicable to a case where a flow control service allocates an available flow credit to a product line. The method may be performed by a flow control device, which may be implemented in hardware and/or software, and may be configured in a flow control service. Referring to fig. 1a, the method specifically comprises the following steps:
s110, determining the number of target peer nodes in the peer-to-peer content distribution network; wherein the target peer node has synchronized the resource data of the product line.
And S120, distributing available flow quota for the product line according to the number of the target peer nodes, and providing resource downloading service for the product line according to the available flow quota.
Fig. 1b is a schematic diagram of a peer-to-peer content delivery network provided according to an embodiment of the present application, and referring to fig. 1b, the peer-to-peer content delivery network may include a content delivery network (Content Delivery Network, CDN) and a peer-to-peer network (Peer to Peer Network, P2P). The business of the product line can upload the resource data of the product line to the resource center, the resource center deploys the resource data of the product line to the CDN, part of P2P nodes in the P2P network can synchronize the resource data of the product line from the CDN, and part of P2P nodes can synchronize the resource data of the product line from other P2P nodes, namely, different P2P nodes can synchronize the resource data of the product line, so that the transmission efficiency of the resource data is accelerated. The resource data may be an upgrade package, a client application program, or a network resource, which is not specifically limited in the embodiment of the present application.
In the implementation of the present application, the flow control service may periodically determine the number of target peer nodes in the peer-to-peer content distribution network, and dynamically allocate an available flow credit to the product line according to the number of target peer nodes. The available traffic quota of the product line may be positively correlated with the number of the target peer nodes, that is, the greater the number of the target peer nodes, the greater the available traffic quota of the product line. Specifically, in different charging periods, the number of target peer nodes is different, and the available flow rate limit of the product line is different. The duration of the charging period may be set according to service requirements, for example, may be 300S, which is not specifically limited in the embodiment of the present application.
The number of the target peer nodes is dynamically determined in the process of synchronizing the resource data of the product line in the peer-to-peer network, and the available flow limit is dynamically distributed to the product line according to the number of the target peer nodes, so that in the process of synchronizing the resource data of the product line, the resource downloading service of the product line is provided according to the available flow limit of the product line, and compared with the method that the resource data downloading service of the product line is provided after the resource data of the product line is synchronized, the resource downloading efficiency can be improved, and the waiting time of manufacturers of the product line is shortened.

Specifically, taking the resource data of n product lines needed by the user equipment, the resource data of m product lines needed by the P2P network as seeds, the CDN traffic charging is F element/TB, the P2P traffic charging is a×f element/TB (where a is the ratio of the peer-to-peer network service cost to the content delivery network service cost), the cost of providing the resource download service by adopting the peer-to-peer content delivery network is n×a×f+m×f, and the cost of providing the resource download service by adopting only the CDN is n×f, so that the peer-to-peer content delivery network is adopted to provide the resourceThe source download service is cost-effective compared to using only CDN to provide the resource download service
