We study an SDN-enabled EPON architecture that utilizes application information from clients to achieve superior upstream resource allocation. This leads to better quality of experience of video-conferencing clients which are high consumers of upstream bandwidth.
As bandwidth requirements of users in passive optical networks continue to increase rapidly, especially due to the growth of video-streaming traffic, the need to resolve bandwidth contention among competing users and applications becomes more compelling. To address this problem, we propose application-aware software-defined Ethernet passive optical network (EPON) architecture. It utilizes application-level...
As bandwidth requirements of access networks continue to increase rapidly, especially due to the growth of streaming traffic, the need for resolving bandwidth contention among competing users and applications becomes more compelling. The proposed Software-Defined Ethernet Passive Optical Network (EPON) architecture utilizes an application-level feedback from the client side (for video users) to the...
Energy usage in our networks is increasing rapidly; and to conserve energy, progress has been made in designing energy-efficient passive optical networks, which are being widely deployed for broadband access. Among the various energy- saving techniques, enabling sleep mode in optical network units is a very promising approach. However, the slow transition of power from active mode to sleep mode in...
We propose an SLA-based scheduling scheme for EPON in which OLT can adjust sleep time and ONU can quit sleep mode for sending expedited frames. Considerable energy can be saved under practical power consumption settings.
