The Case for a Network Calculus Heuristic: Using Insights from Data for Tighter Bounds

This repository contains the dataset used for the paper "The Case for a Network Calculus Heuristic: Using Insights from Data for Tighter Bounds" published at the 2018 International Workshop on Network Calculus and Applications (NetCal 2018). We refer to the paper for a full explanation of the methodology used for generating the dataset.

## Reading the dataset

The dataset is split in two files:

  • dataset_itc30nc.networks.pb.gz describes the network of servers with their rate and latency parameter, and the flows with their path, and their rate and burst parameters.
  • dataset_itc30nc.results.pb.gz contains numerical evaluations of the networks using DiscoDNC v2.4.0.

Each file is encoded using Protocol Buffers. The data structure is defined in dataset_itc30nc.proto and can be compiled to various target languages (e.g. Java, Python, Objective-C, and C++) using the protoc command line utility.

Example code in python

We first compile the .proto file to python:

$ sudo apt install python3-protobuf
$ git clone https://github.com/fabgeyer/dataset-itc30nc
$ cd dataset-itc30nc
$ protoc --python_out=. dataset_itc30nc.proto

The following script can then be used for reading the data:

import gzip
import dataset_itc30nc_pb2 as pb2

def parse(filename_networks, filename_results):
	networks = pb2.Dataset()
	with gzip.open(filename_networks, 'rb') as fhandle:
		networks.ParseFromString(fhandle.read())
	print(networks)
	
	results = pb2.Results()
	with gzip.open(filename_results, 'rb') as fhandle:
		results.ParseFromString(fhandle.read())
