 The new delay node supports variable delays based on various probability distributions such as: Poisson, Normal and Exponential. Moreover, it
-enhances some of the functions for a more realistic link emulation. "make-new-lan" command create a LAN that uses this new delay node to control bandwidth, add probabilistic delays and induces sophisticated loss pattern. make-new-lan parameters are the nodelist, bandwidth, delay properties, and loss pattern description. To create a LAN, connecting three nodes, with a static delay of 30ms, 1Gb bandwidth and a static loss of threshold 0.1 and a rate of 1.

-make-new-lan receives the arguments in any order e.g you could provide delay parameters before loss one, however, nodelist should be the first. Note that bandwidth parameters have to be preceded by "bw", delay with "delay", and loss with "loss". The user only have to provide the nodelist, others are optional, but once she provide any it has to be provided in the correct format.The command is described by:

 Delay types are : static, normal , poisson and exponential. Note that normal requires standard variation, which is set to zero if not provided.
