snmp-query-engine - multiplexing SNMP query engine
snmp-query-engine daemon accepts multiple
client connections and performs SNMP queries
towards multiple destinations on behalf of its clients,
taking care of multiplexing and throttling the requests.
This allows querying large number of devices for
large amounts of SNMP information quickly,
while controlling the load on the devices
induced by multiple SNMP queries.

With regard to msgpack dependency: snmp-query-engine requires at least msgpack 0.5.7, previous versions have bugs. Unfortunately, msgpack website has changed its layout substantially, so it is not easy to find the release source anymore. One possibility is to fetch 0.5.7 from http://msgpack.org/releases/cpp/msgpack-0.5.7.tar.gz
