XG‐PON is the latest ITU‐T PON standard for passive optical networks (PONs), which
provide broadband access to the end user at line rates of up to 10 Gb/s. The most important …

A passive optical network (PON) combines multiple service providers' in a ubiquitous city (u-
City) without suffering from a bandwidth bottleneck. Multiple optical line terminals (multi …

Service providers emphasize the need for faster, cheaper and more reliable deployment of
broadband networks, therefore making the hardware manufacturers pursue innovative …

In this letter, we investigate optical cross-connect (OXC) port dimensioning strategies for
supporting bandwidth-on-demand (BoD) services in optical networks. At a given node, the …

Passive optical networks bring high-speed broadband access via fiber to the business, curb
and home. Among various types of PONs, Ethernet PONs are gaining more and more …

Virtualization improves the efficiency of networks by allowing multiple virtual networks to
share a single physical network's resources. Next-generation optical transport networks are …

This paper presents a minimum cost maximum flow (MCMF) based upstream bandwidth
allocation algorithm, which supports differentiated QoS for orthogonal frequency division …
