In this paper, passive optical network and its techniques have been reviewed. Due to the property of high bandwidth and energy saving, Passive optical network can be a better solution for the networks accessed in future. Traffic pattern has evolved to video and image based services from voice and text oriented services in the access networks. For the support of symmetric, high-speed and perfect...

Traces of filesystem activity have proven to be useful for a wide variety of purposes, ranging from quantitative analysis of system behavior to trace-driven simulation of filesystem algorithms. Such traces can be difficult to obtain, however, usually entailing modification of the filesystems to be monitored and runtime overhead for the period of the trace. Largely because of these difficulties,...

In this editorial, we first set the context for the subject matter of this special issue on passive optical network (PON) supported networking. This context includes a discussion of optical networking in all segments of a global communication network and the emphasis of the importance of PONs in the access network as well as their role supporting other communication network technologies. We fol...

Expanding size of passive optical networks (PONs) along with high availability expectation makes the reliability performance a crucial need. Most protection architectures utilize redundant network components to enhance network survivability, which is not economical. This paper proposes new self-healing protection architecture for passive optical networks (PONs), with a single ring topology and ...
