    7144Delay types are : static, normal , poisson and exponential. Note that normal requires standard variation, which is set to zero if not provided.
    7245loss dropmodes are static and poisson. Also notice that the default bandwidth is 1Gb.
    … …  
    7548The loss model is more sophisticated.It adds the ability to drop packets based on different parameters. The user can adjust the parameters to achieve any desirable pattern. Dropping packet is based on a threshold x; x ≥ 0.000001 and x ≤ 1 which is given by the user. For each received packet, if not in the dropping state, the element generates a uniform random number r ∈ [0.000001, 1] if r ≤ x then it enters the dropping mode. It has to drop σ packets to leave the dropping state. σ is either a static value given by the user or a random number belongs to a Poisson distribution. To set up a dropping mode with static dropping rate the dropmode should be set to "static".
