Detailed Description

Implementation of a simple WDM node.

The basic Node class maintains a set of outgoing Link objects, indexed by the destination (or next-hop) addresses. The main functionality of the Node is to manage setup and teardown functions only on it associated links.

Member Function Documentation

const int common::Node::getNodeId (   )  [inline]

Get the node identifier. Returns: the node identifier

void common::Node::setNodeId (  u_int  nodeId  )  [inline]

Set the node identifier. Parameters: A  node identifier

bool common::Node::addLink (  u_int  dest, u_int  chCount )

Add a new Link to the node with the provided information. Parameters: dest  The destination node chCount  The number of channels/wavelengths in the link Returns: True on a successful add, false otherwise.

int common::Node::scheduleLightpath (  long  lightpath, u_int  dest )

Scedule a lightpath on the pre-specified link. Parameters: lightpath  A specified lightpath identifier (unique) dest  Represents the next hop from that node. Returns: The wavelength the lightpath is scheduled or -1 in case of lack of schedule, -2 if the lightpath is already present, -3 if the link is not present -4 input lightpath is faulty

int common::Node::scheduleLightpath (  long  lightpath, u_int  dest, int  wavelength )

Scedule a lightpath on the pre-specified link. Parameters: lightpath  A specified lightpath identifier (unique) dest  Represents the next hop from that node. wavelength  Represents the wavelength on that specific link. Returns: The wavelength the lightpath is scheduled or -1 in case of lack of schedule, -2 if the lightpath is already present, -3 if the link is not present -4 input lightpath is faulty

int common::Node::removeLightpath (  long  lightpath  )

Remove a lightpath by searching any traces of it on all the possible links of this node. Parameters: lightpath  The lightpath identifier Returns: A positive integer on a successful removal, -1 if not found.

bool common::Node::isLinkPresent (  u_int  dest  )

Checks if a link is already present in the link map. Parameters: dest  A link to the destination Returns: a true is returned if a link is present false otherwise.

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

Convert the representation of this object to a string form. Returns: A String object Reimplemented in common::GroomerNode.
