In this paper a 3-level quality of service (QoS) scheduling is applied to a reference Data Center (DC) optical core switch with wavelength conversion and queueing capability. The scheduling approach is able to manage guaranteed traffic and statistical multiplexed traffic, this last further divided in pure loss traffic and delay tolerant traffic. With respect to previous works mainly focused on aggregation...
This paper describes an analytical model for a 3-level quality of service scheduling in hybrid optical networks. Three service profiles with different requirements are considered, namely: guaranteed transparent service, where packets are transparently forwarded into pre-established paths; real-time statistically multiplexed packet service, where real-time packets are forwarded with limited delay;...
This paper describes the congestion resolution mechanism adopted in the network interfaces of the 3-Level Integrated Hybrid Optical Network (3LIHON). In 3LIHON, three service levels, namely guaranteed transparent service, real time statistically multiplexed packet service, and best effort basic Internet service are considered. The proposed mechanism is designed to meet Quality-of-Service requirements...
