Defining Quantiles for Estimating IP Packet Delay Variation in NGN Core Networks

Throughput metrics and packet delay in TCP/IP networks

In the paper the method for estimation of throughput metrics like available bandwidth and end-t-end capacity is supposed. This method is based on measurement of network delay Di for packets of different sizes Wi. The simple expression for available bandwidth Bav = (W2−W1)/(D2−D1) is substantiated. The number of experiments on matching of the results received new and traditional methods is spent...

Time Synchronization in Wireless Sensor Networks: Estimating Packet Delay

A significant challenge when implementing time synchronization protocols is minimizing timestamp uncertainties. The major problem of time synchronization is not only that this packet delay exists, but also being able to predict the time spent on each can be difficult. This paper aims to reduce these uncertainties by estimating them in the transmitter and receiver thus greatly increasing the per...

Estimating End-to-End Cell Delay Variation in ATM Networks

Cell delay variation (CDV) is one of the quality of service parameters that can be negotiated between applications and an ATM network. The network should check during connection setup, as part of call admission control, whether it can satisfy the requested CDV of an application. For this comparison, the network should estimate the end-to-end CDV that it can support, by using local information a...

A recursive formula for estimating the packet loss rate in IP networks

We present a recursive formula for estimating the packet loss rate in IP networks. Specifically, we consider a single link whose capacity is shared dynamically by elastic data flows, each characterized by some peak rate, and derive the formula from the steady-state distribution of the number and peak rates of ongoing flows. The result is particularly useful for dimensioning ISP backhaul network...
