Today’s digital frontier can be described as the new Wild West with untested cutting-edge technologies finding their way into the public domain. With increased interest in Gigabit Passive Optical Networks (GPON) to provide LAN access, one question must be asked. What is the risk? Risks associated with traditional Ethernet LAN technologies are well known and documented. As is common with new tec...

A detailed understanding of the many facets of the Internet’s topological structure is critical for evaluating the performance of networking protocols, for assessing the effectiveness of proposed techniques to protect the network from nefarious intrusions and attacks, or for developing improved designs for resource provisioning. In this way Available bandwidth estimation is a vital component of...

It is expected that the requirements for access networks will change in the future due to the increase in bandwidth demand, due to the shift to packet based services and due to the drive to implement a full service network. Optical access networks are a logical implementation of these requirements. Of all the access infrastructure available, optical fiber has the largest bandwidth potential. In...

201 Abstract— A detailed understanding of the many facets of the Internet’s topological structure is critical for evaluating the performance of networking protocols, for assessing the effectiveness of proposed techniques to protect the network from nefarious intrusions and attacks, or for developing improved designs for resource provisioning. In this way Available bandwidth estimation is a vita...

Current optical networks are migrating to wavelength division multiplexing (WDM)-based fiber transport between traditional electronic multiplexers/demultiplexers, routers, and switches. Passive optical add–drop WDM networks have emerged but an optical data network that makes full use of the technologies of dynamic optical routing and switching exists only in experimental test-beds. This paper w...

Byungjoo Park et al. 301 As broadband access is evolving from digital subscriber lines to optical access networks, Ethernet passive optical networks (EPONs) are considered a promising solution for next generation broadband access. The point-tomultipoint topology of EPONs requires a time-division multiple access MAC protocol for upstream transmission. In this paper, we propose a new enhanced dyn...

Contemporary deployments of optical access networks are based on the principles of Passive Optical Networks (PONs). PONs deploy a star topology and dual wavelength for communication between the center and ends of a star. The star topology requires that each end-user be connected to the star splitter (usually a passive coupler). We argue in this paper that while adhering to the requirements of a...
