An Architecture for IP Over WDM Using Time-Division Switching
نویسندگان
چکیده
This paper proposes an architecture for routing Internet protocol (IP) packets directly on optical networks. The use of label switching is assumed in the IP routers, while a new routing architecture is introduced to transport IP packets across an optical backbone network. The architecture is based on a two-tier multiplexing approach, with wavelength division multiplexing (WDM) addressing the number of regional exchanges and time-division switching communicating among the hubs. Such an architecture not only has the advantages of simple network management and high efficiency with low latency; it also is scalable by addition of regional exchanges, hubs, and fibers.

Optical Burst Switching: A Viable Solution for Terabit IP Backbone
Wavelength-division multiplexing has emerged as an important physical layer technology. Optical transmission provides a physical layer capable of carrying bits at the speed of the order of a gigabit per second. Optical burst switching is proposed to overcome the shortcomings of conventional WDM deployment, such as lack of fine bandwidth granularity in wavelength routing and electronic speed bot...
متن کاملFLAMINGO: A Packet-switched IP over WDM Metro Optical Network
We present a network architecture of an all-optical wavelength-and-time-slotted Metropolitan Optical Network. A couple of important aspects of this architecture include all-optical packet switching and the ability to put IP packets directly over WDM. Since the FLAMINGO network has a ring topology we focus on issues such as chromatic dispersion and network synchronisation and suggest ways and me...

Optical burst switching (OBS) has been proposed as a switching technique to exploit enormous amount of capacity provided by wavelength division multiplexing (WDM) transmission technology. In this paper, we consider a model for overlaying IP network over the OBS WDM transmission backbone. In the framework of this model, the functional requirements of the interface between the IP layer and the OB...

In this paper we propose a simple model that analyzes the cost saving achieved by Optical IP Switching (OIS), a novel optical architecture, compared to a conventional IP-over-WDM network, where the IP router connects directly to the WDM module. The analysis we propose shows that OIS can bring substantial cost savings in the initial investment of network operators.
متن کاملExperimental study of dynamic IP topology reconfiguration in IP/WDM networks
With the widespread deployment of IP over WDM networks, it becomes necessary to develop dynamic lightpath and topology reconfiguration mechanisms and reconfiguration triggers that can effectively exploit WDM reconfigurability. A reconfiguration model for overlay IP/WDM networks is introduced. An IP over WDM network testbed has been set up using Telcordia MONET WADMs and IP routers. The testbed ...
