Capacity and delay analysis in Passive Optical Networks (PONs) - A review
The dramatic increase of internet users and development of new high volume internet applications has a profound impact on design of Next Generation Passive Optical Network (NG-PON). Today, most of the available networks are quite busy networks and as the number of nodes increases in the network, the communication over the network also increases. A reliable end packet delivery is always one of the basic requirements of a user as well as network. When the data is transferred over the network there are many major causes that can result packet loss, such as congestion over the network.
