The goal of long haul DWDM transmission is to deliver error-free digital information at extremely high data rates and over very long distances, ideally without the need for regeneration of the signal. Forward error correction (FEC) is a method of ...
Disaster-aware service provisioning with manycasting in cloud networks
Cloud services delivered by high-capacity optical datacenter networks are subject to disasters which may cause large-area failures, leading to huge data loss. Survivable service provisioning is crucial to minimize the effects of network/datacenter ...
Efficient IP lookup using hybrid trie-based partitioning of TCAM-based open flow switches
IP forwarding technique in open flow switch can be done by comparing the destination IP address, which is stored in forwarding table with the input IP prefix. Ternary content-addressable memory (TCAM) is one of the popular mechanisms to store and ...
Routing, wavelength assignment and spectrum allocation for reconfigurable optical mesh networks having a combination of fixed and flexible spectrum ROADM nodes
Next generation of optical networks will witness the advent of flexible spectrum/grid reconfigurable optical add drop multiplexers (ROADMs). The pass band of these next generation ROADMs can be varied depending on the spectral width of the incoming ...
Fault tolerance mechanisms for virtual data center architectures
A virtual data center (VDC) is a combination of interconnected virtual servers hosted on a physical data center that hosts multiple such VDCs. This enables efficient sharing of the data center's resources while handling dynamic resource requirements of ...
Using OpenFlow to provide cut-through switching in MobilityFirst
Mobile devices are expected to become the Internet's predominant technology. Current protocols such as TCP/IP were not originally designed with mobility as a key consideration, and therefore underperform under challenging mobile and wireless conditions. ...

We present different mechanisms for downstream transmissions in the coax segment of Ethernet Passive Optical Network (EPON) Protocol over Coax (EPoC). EPoC is the transparent extension of EPON over a cable operator's Hybrid Fiber-Coax network. For ...
POST: a scalable optical data center network
In this paper, we propose a wavelength division multiplexing-based power efficient data center interconnect called Passive Optical Scalable Tree data center network (POST). POST is a highly scalable tree structured network that interconnects thousands ...
