This choice largely depends on what protocol(s) your device(s) support for monitoring.In this screen you need to choose which protocol to use.
|Universal Plug and Play (UPnP)|
UPnP (Wikipedia: Universal Plug and Play) is a network protocol designed to control and manage network devices, media players and other interactive appliances. Most (but not all) network devices (routers, WiFi access points etc) support basic monitoring of the WAN (Internet) interface using UPnP. If the device supports this feature, PeakHour can monitor it.
For more information on UPnP, see the UPnP Wiki entry.
|Simple Network Management Protocol (SNMP)|
SNMP is a widely supported, enterprise-grade management protocol that has been in existence since the late 1980s. SNMP is mostly found in higher end routers and network equipment such as Apple's Airport Express/Extreme/Time Capsule (although sadly not the new Airport Extreme 'AC' version), Cisco, Juniper, servers, switches and servers.
For more information on SNMP, see the SNMP Wiki entry.
To find out what protocols your device(s) support, we suggest you refer to the documentation for that device, or the management interface.
As a rule of thumb, we suggest using SNMP if at all possible. SNMP is designed specifically for the type of monitoring that PeakHour does and contains several features that make monitoring more accurate (which UPnP does not).
