Abstract

The embodiment of the invention discloses a network flow control method and device. The method applied to a client comprises the following steps: receiving data packets which are sent by different data packet supply nodes and are specific to the same target stream, wherein each data packet carries a data packet lagrange multiplier which is specific to the target stream, to which the data packet belongs, and corresponds to the data packet supply node which sends the data packet; extracting the data packet lagrange multipliers from the received data packets; according to all the extracted data packet lagrange multipliers, calculating a first sending rate of each data packet supply node for the data packet of the target stream to which the data packet belongs; for each data packet supply node, according to the first sending rate corresponding to the data packet supply node, calculating a second sending rate for sending an interest packet to the data packet supply node; and sending the interest packet to each data packet supply node at the second sending rate, so as to control the network flow. By the implementation of the network flow control method, the network resource utilization rate in an NDN (Named Data Networking) is increased.

Description

technical field [0001] The invention relates to a wireless communication system, in particular to a network flow control method and device. Background technique [0002] Named Data Networking (NDN, Named Data Networking) is a new type of network architecture. The biggest difference between it and the TCP / IP (Transmission Control Protocol / Internet Protocol) architecture is its design idea - information-based center. NDN separates the data containing information from the location, and shifts from "focusing on the communication between two points" of the TCP / IP architecture to "focusing on the content itself". [0003] Communication in NDN is driven by clients through the exchange of Interest and Data packets. The client sends a certain number of interest packets to request data. For these interest packets, multiple nodes can provide the same number of data packets as feedback. The above-mentioned whole process realizes the transmission of "data stream" by NDN. Both the inte...
