Abstract
Description
where γs represents a share of the capacity assigned to each of the xs streaming data sessions and γe represents a share of the capacity assigned to each of the xe elastic data sessions.
with the convention that the result of any summation where the upper index is less than the lower index equals zero.
where αs represents a normalized peak rate to pipe capacity for the streaming data and αe represents a normalized peak rate to pipe capacity for the elastic data.
where Qs represents the peak rate of the streaming data, Qe represents the peak rate of the elastic data and C represents the target capacity of the link, which is being evaluated for QoS compliance in the current instance of the dimensioning process. The value of Qs is determined based upon the type of streaming data, as discussed above.
where the variables, FS, MSS, RTT and PLR are known input parameters, as discussed above.
wherein λ's, as defined earlier, represent mean session arrival rates and {hacek over (Ψ)}(0,0)={circumflex over (Ψ)}(0,0)=1. As discussed above, the φ terms in the denominators of the above equations contain μ terms, which divide into corresponding λ terms in the numerator such that these equations can be restated in terms of terms of ρ terms. While λ's and μ's are typically unavailable, the ρ terms can be calculated alternately from traffic volumes and peak rates as shown later, thus facilitating the computational steps to be described.
Based on the recursive variant Equation (13A), the following algorithmic sequence may be followed to exhaustively compute the weight functions {{hacek over (Ψ)}(0,0) . . . {hacek over (Ψ)}(K,K)} for all the system states {[0,0] . . . [K, K]}:
Set {hacek over (Ψ)}(0,0) = 1; | ||
For (i=0 to K){ |
If (i>0) then calculate {hacek over (Ψ)}(0,i) from Equation (13A); | |
For (j=1 to K) |
Calculate {hacek over (Ψ)}(j,i) from Equation (13A); |
} | ||
{hacek over (π)}(x s ,x e)={hacek over (π)}(0,0){hacek over (Ψ)}(x s ,x e), where {hacek over (π)}(0,0)=1/Σ(x
where ET represents a customer stipulated data throughput rate acceptability threshold for each elastic session (e.g., 800 kilobytes per second (Kbps)), SST represents a customer stipulated data throughput rate acceptability threshold for each stream session (e.g., 800 Kbps) and γe(xs,xe) is defined by Equation (4) above. In the 3-dimensional model, it should be noted that the ET would have two distinct components, ELT and EST, for long elastic data throughput rate acceptability threshold and short elastic data throughput rate acceptability threshold, respectively, where appropriate.
x 1 =x 2 =x 3=0;π[0,0,0]=norm=1; Eq. (21)
