Analysis of Capacity and Delay in Passive Optical Networks (pons)

With the continuous increase in bandwidth demand generated by consumer and business applications, a new higher capacity access network is required. Today, with the development of electronic media and its usage most of the networks having more number of nodes and as the number of nodes increases in the network the communication over the network also increases. A reliable end packet delivery is the basic requirement of a user as well as network. Heavy traffic over any network gives the problems like congestion, degradation in throughput. There are number of such network in which different kind of data is being transferred in terms of multicast and broadcast. The growing popularity of internet, video on demand, video conferencing, and gaming are the key factor behind the development of new access method which would meet the bandwidth requirement. The Passive Optical Network (PON) and Gigabit Passive Optical Network (GPON) resolve most of the above defined problem. PON can reduce the packet loss and return reliable data transmission over the network. As PON provide large bandwidth http://www.ijccr.com International Manuscript ID : ISSN2249054X-V2I3M5-052012 VOLUME 2 ISSUE 3 May 2012 that it will never gives efficiency problem in the network. The PON can also resolve the bottleneck problem along with the delay analysis over the bottleneck congested network. KeywordsGPON, packet delay, passive optical network, throughput-delay analysis.
