The user can choose between several types of reports according to nodes, lightpaths, links and flows. The built-in MILP algorithm allows to select among several options for the planning process:. The traffic matrix will be like this:. First, it tries a direct lightpath from ingress to egress node. The electronic switching equipment is connected by lightpaths.

If a flow 'f' uses a lightpath 'l', matplqnwdm entry f,l is equal to the part of the flow 'f' carried by the lightpath 'l'.
WDM networks planning under multi-hour traffic demand with the MatPlanWDM tool - EUDL
The Physical Topology panel plots the physical topology of the design. Per node information reports can be generated that summarize the evolution of one selected metric across the nodes and along time.
After completing this stage, the matrix generated is reported in the Traffic file field in the right side of the window. This provides fast access to relevant information like the time evolution in the number of used transmitters, receivers or converters. The rightmost panel is a text area where the simulation input parameters and results are written at the end of the simulation and if you click the Show Stat or Show State buttons.
Cahn, Wide area network design: Added new GUI and simulation kernel to test also dynamic planning algorithms.
MatPlanWDM Manual
It is a vecor as many rows as 'M' physical links. These are processed as follows:.
This eases the evaluation and comparison among different solutions. The planning algorithm module is an. The Dynamic Analysis GUI allows us to test on-line optimization algorithms react to higher level traffic connections arrivals and terminations. The next table shows these parameters with its their mtplanwdm values, data types and valid ranges:.
This directory includes the planning algorithms and the library functions used to compose them. Now we can continue explaining how to extend the tool. Updates 8 May 1. File, Mode, Tools and Help.
If this fails, it computes the set Seg of nodes that are connected to the egress node by a lightpath of enough capacity. Select a Web Site Choose a web site to get translated content where available and see local events and offers.
This schedules the next flow arrival. It is recommended a screen resolution of x Tags Add Tags cplex error for t The default values for the parameters not set are: The objective is to design a virtual topology defined by a set of decision variables by optimizing a certain cost function subject to a set of constraints.
The matrix can be non-symmetrical. As a result, the main menu will be opened. It is selected so that the average traffic injected matches the i,j coordinate of a given traffic matrix. The following figure shows the structure of a. Figure 30 helps us to describe the structure of the toolbox.
The XML files generated as outputs in the Multi-hour scenario contain as many virtual and traffic layers as number of considered time slots.

The simulation can be stopped with the Stop button or the End Simulation button. After this, the user can select in the Pattern generation selector, among different matlanwdm ways of generating a matrix. The distribution based on populations and distances follows the next expression:.
The Figure 6 displays the workspace window, which contains an input data area, a physical topology plot area, a text field for report, and an area to draw the performance curves generated.
This function computes the "K" different mwtplanwdm paths between a pair of nodes ingress node, egress node. This problem consist of finding the traffic flow routing between two nodes ingress node and egress node with the minimum cost.
