* 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
| Plan | Down | Up | | | | | | |
|----------------------+------+-----+---+---+---+---+---+---|
| WiFi | | | | | | | | |
| Cable | 2ms | 6ms | | | | | | |
| Docsis LL | 1ms | | | | | | | |
| Wireless half duplex | | | | | | | | |
* Test tools
** Flent
** goresponsiveness
** crusader
** speedtest.net
** samknows
** Netflix video quality
** VOIP MOS
** Videoconferencing Quality
* Congestion Controls
