Package jline.api.snc

Class Snc_output

java.lang.Object

jline.api.snc.Snc_output

public final class Snc_output
extends Object

Output (departure) arrival envelope of a flow leaving a server.

For independent processes and a stable station,

   rho   = rhoA,
   sigma = sigmaA + sigmaS - log(1-exp(-theta*(rhoS-rhoA)))/theta.
 

The rate is conserved and the server adds burstiness. This is what carries a flow across a feed-forward network one hop at a time; for a tandem traversed by the same flow, Snc_conv gives the tighter end-to-end result.

Port of matlab/src/api/snc/snc_output.m.

Method Details

snc_output

public static double[] snc_output(double sigmaA,
 double rhoA,
 double sigmaS,
 double rhoS,
 double theta)

Parameters:

sigmaA - burst term of the arrival envelope

rhoA - rate term of the arrival envelope

sigmaS - burst term of the service envelope

rhoS - rate term of the service envelope

theta - Chernoff parameter, theta > 0

Returns:

{sigma, rho} of the departure envelope; sigma is Infinity when the station is unstable

of

public static SncEnvelope of(SncEnvelope arv,
 SncEnvelope srv)

Parameters:

arv - the arrival envelope entering the server

srv - the service envelope

Returns:

the departure envelope as a function of theta
