Motivation and Background Enterprise WLANs highly IP-centric and switched WLAN switches and lightweight APs Layer 3/4 aware (sometimes even Layer-7 aware) Incorporates many IETF-defined functions: ARP caching and proxying, DHCP service, firewalling, IPsec, etc Considerable work in IETF in this area CAPWAP – WLAN switch protocols MANET – WLAN mesh protocols Equipment vendors would like to use the same benchmarking techniques as their customers, for measuring WLAN switch and mesh performance It’s all very ad-hoc today Test tool vendors would like to have the same approach to testing as service providers and equipment vendors |
