ContStateGMPPDistribution 
ContinuousState GMPP
Meaning:
Modeling of sources where the state space is continuous.
 Description:
State machine with continuous (infinite) state space:
length of a state according to a continuous distribution
rate \(r\) in a state according to a continuous distribution
Poisson process with rate \(r\) within a state
 Parameters:
continuous distribution of the length of a phase
continuous distribution of the rate in a phase
 Characteristic values:
Moments and distribution of the arrival intervals
 Parser example:
[...].distribution = ContStateGMPP
[...].distribution.PhaseLengthDist = NegExp
[...].distribution.PhaseLengthDist.Mean = 2.3
[...].distribution.RateDist = Uniform
[...].distribution.RateDist.LowerBound = 1.5
[...].distribution.RateDist.UpperBound = 3.5

GMDPDistribution 
GMDP (Generally Modulated Determistic Process)
Meaning:
Modeling of sources with multiple states (usually 2  5) in ATM networks
 Description:
A GMDP comprises a state machine with \(m\) states:
In state \(i\) arrivals occur in constant intervals \(d_i\).

MMDPDistribution 
MMDP (Markov Modulated Deterministic Process)
Meaning:
Most frequent special case of the GMDP (
GMDPDistribution ) for
modeling sources with multiple states (generally 2  5) in ATM networks
 Description:
Like the GMDP(
GMDPDistribution ), the
MMDP can be described by a state machine with \(m\) states.

OnOffInfinityDistribution 
OnOff Infinity Model
Meaning:
Superposition of infinitely many onoff sources which allows the
modelling of aggregated traffic.

TalkspurtSilenceDistribution 
Talkspurt Silence Source
Meaning:
Modeling of onoff sources in packet networks
Modeling of voice sources
 Description:
State machine with 2 states (on/off, talkspurt/silence or burst/silence)
In the talkspurt state \(X\) cells/packets arrive at intervals of \(d\).

VideoSourceDistribution 
Video Source
Meaning:
Modeling of video sources in ATM/packet networks
 Description:
Parameters: frame duration \(d_F\), frame size \(s_F\), packet size \(s_P\)
Autoregressive process with the bit rate \(\lambda_i\) in frame \(i\) in
bits/pixel: \(\lambda_i = (a \cdot \lambda_{i1} + b \cdot \varepsilon) \cdot
r(0,\lambda_{max})\) with the constants \(a\) and \(b\) as well as the
function \(r\) to limit the rate to the interval \([0,\lambda_max]\).

WSSDistribution 
WSS (Wide Sense Stationary Process)
Meaning:
Noise generator (conversion of white noise to bandwidthlimited, colored
noise with the help of a filter)
 Description:
White noise at the input of a filter is uniformly distributed in the interval
\((\sqrt{3}, \sqrt{3})\).
