inSingle - Hop All - Optical Networks with Blocking
We consider single-hop all-optical networks in which wavelength-routed connections (lightpaths) between source-destination pairs are dynamically established and torn down in response to a random pattern of arriving connection requests and connection holding times. A connection request may be blocked if no wavelength is available on a suitable path from source to destination. For these networks ...
متن کاملTraffic Grooming and Blocking Optimization in all-optical Networks
The paper proposed an efficient traffic grooming model for all optical networks. The model has low complexity and it can be easily implemented for traffic grooming problems. It is used to calculate the blocking probability of computer networks and then grooming problems are addressed based on the calculated blocking probability. Blocking probability is considered to be a major parameter during ...
متن کاملBlocking Analysis for Time-space Switched All-optical Networks
Optical time division multiplexing (OTDM) allows multiple traffic streams to share the bandwidth of a wavelength efficiently. In this paper, we present a new analytical model, based on the inclusion-exclusion principle from combinatorics, for evaluating the blocking performance of time-space switched optical networks with fixed routing and random wavelength/timeslot assignment. This model can b...
متن کاملMinimizing Request Blocking in All-Optical Rings
In all-optical networks that use WDM technology it is often the case that several communication requests have to be blocked, due to bandwidth and technology limitations. Minimizing request blocking is therefore an important task calling for algorithmic techniques for efficient routing and wavelength assignment. Here we study the problem for rings under both the undirected and the directed setti...
متن کاملSecuring All-Optical Networks
All-optical networks (AONs) are a relatively new technology for high data-rate communications. They contain only optical components and are intrinsically different from optical networks currently being used. More specifically, AONs provide transparent features that allow routing and data switching without necessitating the interpretation or regression of signals within the network. Consequently...
