Title: METHOD AND DEVICE FOR SENDING AND RECEIVING DATA, SERVER, AND COMPUTER PROGRAM PRODUCT
Abstract:
Provided are a method and device for sending and receiving data, a server, and a computer program product. The method for sending data comprises: detecting the quality of a link between a first-level cache and a second-level cache, or detecting a bandwidth utilization rate of the second-level cache, so as to obtain a detection result, wherein the first-level cache is a cache, in a content delivery network (CDN), distributed near to a user and is used for caching data of user access, and the second-level cache a cache, in the CDN, for centralized back-to-source; and when the detection result is that the quality of the link between the first-level cache and the second-level cache is lower than a first threshold value, or the bandwidth utilization rate of the second-level cache is lower than a second threshold value, using a UDP to send data in the first-level cache based on an ARQ. Data transmission may be effectively accelerated and the bandwidth utilization efficiency is improved.
