Detailed Description

Implementation of a SLW converter architecture node.

In addition to the basic WDM node (or Node). This node contains a set of tunable TX and a tunable RX arrays, which is considered as a limited resource that can contribute to lightpath blocking.

Member Function Documentation

int common::GroomerNode::scheduleAny (  long  lightpath, u_int  nextHop, int  prevWavelength )

Scheduling methods for a lightpath. Checks to see if a specific lightpath has enough resources in order to be scheduled in here. I. The first step is to check to see if a lightpath can be scheduled on the same wavelength as the previous in order to avoid electronic conversion. II. If wavelength is not available, then a check is made to see if necessary Tx and Rx are present so as to fill in the need for wavelength conversion. Returns: The result of the scheduleAny operation. (The wavelength)

int common::GroomerNode::scheduleSource (  long  lightpath, u_int  nextHop )

Scheduling methods for a lightpath. Checks to see if a specific node has enough resources to originate a lightpath as this node. Needs two resources I. A wavelength II. A Tx to transmit the lightpath on the wavelength. Returns: The result of the scheduleSource operation (The wavelength)

int common::GroomerNode::scheduleDestination (  long  lightpath, int  prevWavelength )

Scheduling methods for a lightpath. Checks to see if a specific node has enough resources to terminate a lightpath as this node. Needs two resources II. A Rx to receive the lightpath on the wavelength. Returns: A value prevWavelength >= 0 in case of success, -5 if no RX is available

int common::GroomerNode::scheduleSpecific (  long  lightpath, u_int  nextHop, u_int  prevWavelength )

Scheduling methods for a lightpath. This methods tries to see if a wavelength is available. It does not carry out wavlenght conversion at the intermediate node. Needs on wavelength resource Returns: the result (wavelength)

int common::GroomerNode::clearSchedule (  long  lightpath  )

Remove the specified lightpath. Parameters: lightpath  The lightpath to be removed Returns: The result of the operation.

std::string& common::GroomerNode::toString (   )  [virtual]

Convert this object's representation to String. Returns: A string representation of this object Reimplemented from common::Node.
