ABSTRACT
Optical packet switching promises to bring the flexibility and efficiency of Internet to transparent optical networking with bit rate extending beyond that currently available with electronic router technologies. New optical signal processing have been demonstrated that enable routing at bit rates from 10gb/s to beyond 40gb/s.in this article we review these signal processing techniques and how all optical wavelength converters technology can be used to implement packet switching functions. Specific approaches that ....etc

ABSTRACT
In IP routing each packet travels from one router to the next, each router makes an independent forwarding decision for that packet. That is each router analyses packet header, and each router runs a network layer routing algorithm. Each router independently chooses a next hop for the packet, based on its analysis and the results of running the routing algorithm.
In conventional IP forwarding a particular router will typically consider two packets to be in the same FEC(forward equivalence class) if there i ....etc

Voice over Multiprotocol Label switching
Challenges in IP network
 Shortest path is followed in IP network
 Load sharing is not possible
 Congestion is created in IP network
 Routing in network layer
 Processing is slow and delay is more
SOLUTION TO THE PROBLEM ?
MPLS
• Multi protocol label switching
• Reduces excessive delay
• Instead of shortest follows suitable path on the basis of constraint
• Reduce packet loss
• Provide TE
• Provide QOS ....etc
