Residential gateways play a key role in providing internet access to home consumers. Nowadays, users in the same home with heterogeneous applications share a common gateway. As such, the gateway becomes the bandwidth bottleneck, leading to impairments and negatively affecting users' Quality of Experience (QoE). In the case of delay sensitive applications like video streaming and online gaming, this...
Software Defined Networking (SDN) has provided configurable access to remote network layer components from application hosts during application run-time. We have successfully enabled SDN switches to reduce network resource consumption and improve streaming latency in multi-party 3D tele-immersive (3DTI) applications. Instead of forwarding the same streams to multiple participants from the application...
This paper proposes a new traffic control method to use both pacing and class base queuing (CBQ) methods in the next generation home network. Experimental setup and results are also described to verify the effectiveness of the proposed method. With the pacing and CBQ method applying to the simulated video streaming service in the hardware experiment, its quality of service (QoS) could be improved...
There are many challenges in the QoS controls and traffic handling mechanisms in the deployment of Long Term Evolution (LTE). Simulations are crucial for performance evaluation of end-to-end QoS (Quality of Service) management across LTE network elements over heterogeneous networks. The LTE CoS/QoS Harmonization Emulator presented in this paper will allow the user to determine whether the QoS design...
This paper describes a methodology for building a reliable internet core router that considers the vulnerability of its electronic components to single event upset (SEU). It begins with a set of meaningful system level metrics that can be related to product reliability requirements. A specification is then defined that can be effectively used during the system architecture, silicon and software design...
