Embodiment Construction
[0032] Such as figure 1 As shown in , an intelligent gateway for interaction between wired network and wireless network, the intelligent gateway optimizes and forwards the corresponding data received, the intelligent gateway is provided with an uplink buffer and a downlink buffer, and the uplink buffer is used for The data received by the intelligent gateway is optimized and analyzed, and the optimized and analyzed data is forwarded to the downlink buffer; the downlink buffer optimizes and analyzes the received data again, and then forwards it to the wired network or wireless network that receives the data.
[0033] The uplink buffer performs corresponding parameter control according to the needs of the algorithm, and forwards data to the downlink buffer, and the downlink buffer optimizes the data forwarded by the uplink buffer according to the corresponding algorithm, so that the data meets the requirements of the downlink buffer. The zone matches the network type requiremen...

The invention provides an intelligent gateway for interaction of a wired network and a wireless network. The intelligent gateway optimizes and forwards received corresponding data. The intelligent gateway is provided with an uplink buffer region and a downlink buffer region, wherein the uplink buffer region is used for optimizing and analyzing the data received by the intelligent gateway and forwarding the optimized and analyzed data to the downlink buffer region; the downlink buffer region optimizes and analyzes the received data again and forwards the optimized and analyzed data to the wired network or the wireless network. By means of the intelligent gateway, the uplink data flow and the downlink data flow can basically keep the same average handling capacity under the circumstances of different error rates and numbers of uplink data flows and downlink data flows, and the improvement on the equity aspect is more visible; the competition window of the intelligent gateway is lower, so that channel accessing can be achieved with a higher probability, the handling capacity of the system is improved to a certain extent, and the equity of the uplink flow and the downlink flow is improved effectively, and network performance is improved.
Description
technical field [0001] The invention relates to a gateway used in the Internet field, in particular to an intelligent gateway used for the interaction between a wired network and a wireless network. Background technique [0002] At the wired and wireless border, due to the introduction of the hybrid structure of wired and wireless networks, various problems will arise in the operation of the TCP protocol (Transmission Control Protocol) in the heterogeneous network where wired and wireless networks are mixed. The main problem is that when a packet is lost, the TCP protocol attributes it to network congestion, and based on this, the sending rate will be reduced to alleviate the congestion in the network. However, in a wireless network, data packets will not only be lost due to congestion, but also due to wireless signal interference and other reasons, which is determined by the characteristics of the wireless channel itself. If data packets are lost in a wireless network or a...
