Abstract

Network communication control methods and systems are provided. The length of a sub-time slice is determined according to a network bandwidth, and a transmission threshold of the sub-time slice is determined according to the length of the sub-time slice and the network bandwidth. At least one network transmission is performed within the sub-time slice if a transmission amount of the network transmission within the sub-time slice does not exceed the transmission threshold.
