Attack-Aware Dynamic Upstream Bandwidth Assignment Scheme for Passive Optical Network
Butt, Rizwan Aslam; FAHEEM, MUHAMMAD; Ashraf, M. Waqar; Khawaja, Attaullah; Raza, Basit (Walter de Gruyter GmbH, 2023)Network security is an important component of today’s networks to combat the security attacks. The passive optical network (PON) works at the medium access layer (MAC). A distributed denial of service (DDOS) attack may be ... -
Disaster-resilient lightpath routing in WDM optical networks
Ashraf, M. Waqar; Butt, Rizwan Aslam; Faheem, M; Tariq, M.; Munir, Abid (SPRINGER, 2022)Optical network serves as a core network with huge capacity and a multitude of high-speed data transmission. Natural disasters and physical attacks showed signifcant impacts on the optical networks such as damages the ... -

Sleep assistive dynamic bandwidth assignment scheme for passive optical network (PON)
Butt, Rizwan Aslam; Faheem, M.; Ashraf, M. Waqar; Idrus, Sevia M. (SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA, 2018)In passive optical network (PON), in addition to efficient bandwidth management, a dynamic bandwidth assignment (DBA) scheme can also enhance the energy efficiency performance of the optical networks units (ONUs) during ... -
Sleep-aware wavelength and bandwidth assignment scheme for TWDM PON
Butt, Rizwan Aslam; Faheem, Muhammad; Ashraf, M. Waqar; Arfeen, Asad; Memon, Kamran Ali; Khawaja, Attaullah (SPRINGERVAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2021)The energy efficiency and delay performance of PON are two inversely related phenomena. Higher sleep time of the Optical Network Units (ONUs) results in higher upstream (US) delays due to increased traffic queues during ...
