IP Packet dealy variation

This section contains the definition of the IP Packet Dealay Variation (IPDV), it's accuracy, some recommnedation about the sampling and the statistics which should be retrieved from the samples.

A Singleton Definition for IP Packet Delay Variation

The definition below is the one from the IETF IPPM RFC 3393 with some slight changes to highligths our needs (introduction of ToS and version field) .

Metric Parameters

Src, the IP address of a host
Dst, the IP address of a host
S, a ToS value
V, the IP version field
L, the packet lenght in bits

The Following parameters have to be discussed

T1, T2, two times
F, a function to select unambiguoulsy two packets
I1, I2, times which marks the interval in which the two packets are selected
