In the Long Term Evolution (LTE) network, buffer overflows often occur in the evolved Node B (eNB) when dealing with the traffic bursts from the wired part due to restricted bandwidth or environmental interferences in the wireless part. In this paper, a novel approach is proposed to protect the buffer from overflow by appropriately controlling the advertisement window to enhance the Transmission Control...
Many carrier grade applications require a high availability platform, such as telecommunication systems, nuclear power plants, rockets. A high availability platform can provide reliability, security, upgradeability, scalability and other capabilities to the applications. This paper introduces the key issues when designing a high availability platform, fault prediction, hardware redundancy and fault...
One of the key targets for LTE/SAE is 100 Mbps peak data rate in downlink. While compared to the lined data rate, the wireless data rate is still a bottleneck. This means if there is no flow control in aGW; packets will be buffered in eNB. While the buffer in eNB is limited, packets may be dropped. To reduce the harm to the performance of the TCP based application from packet loss, flow control is...
