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 |
