In recent days, optical fibers have been developed as a transmission medium to carry traffic in order to provide various services in telecommunications platform. Failure of this fibre caused loss of data which can interrupt communication services. Thus, this paper will focus about protection scheme in order to guarantee the survivability of the networks.(More)
Network blocking performance due to wavelength continuity constraint in a well-connected all-optical network can be efficiently reduced by utilizing wavelength converters. Nevertheless, the introduction of high bit rate optical services with strict tolerance to signal quality would have a serious impact on the overall network performance since in this(More)
The Internet is supported by long haul WDM core networks. Reliability is a huge concern in WDM core networks since service disruption would carry significant revenue, reputation and prospect loss. In ensuring reliability to network services, two means of protection scheme are usually used in WDM core networks; dedicated path protection and shared path(More)
Passive optical networks (PONs) require a dynamic bandwidth allocation (DBA) algorithm at the optical line terminal for efficient utilizationofupstreambandwidth among the optical network units (ONUs) as per the quality of service requirements for each traffic class defined by PON standardizing bodies. The GigaPON access network (GIANT) was the first(More)
In food production, sugars (a type of carbohydrate) are widely used to make the food or beverages taste sweet and delicious. Both natural and manufactured beverages may contain a small amount of alcohol (specifically ethanol) as sugar based food is fermentable into alcohol. Therefore, Muslim consumers must be aware that the allowable percentage of alcohol(More)
