Overview

Setting up 4 simulation environments is in order:

Plan Size Characteristics
Small 1024 users
Medium 10000 users
Large 40000 users
Humongous 100k users

IP address ranges

2001:0002::/48 and 198.18.0.0/15 are the experimental address ranges. For testing outside of the network, perhaps a BGP AS for this would help

DNS service

nsupdate for reverse dns? Hosts file?

Subscriber Plans

Plan Name Down Up
4Mbit 384kbit
10Mbit 1Mbit
20Mbit 384
25Mbit 384
50MBit 384
60Mbit 384

Topologies

A variety of topologies need to be emulated.

Distance

Hops

Different technologies

Routing Protocols

Both ISIS and OSPF are in use

Underlying framing

PPPoe, MPLS are in use CGNATs might become an issue IPv6 deploying?

Transport Technologies

WiFi
Cable 2ms 6ms
Docsis LL 1ms
