Systems and methods accessing remote digital data over a wide area network (WAN) are disclosed. In an embodiment, a network device is disclosed. The network device includes a local area network (LAN) switching fabric physical interface configured to communicate according to a LAN switching fabric protocol, a WAN physical interface configured to communicate according to a WAN protocol, and a fabric extension function configured to map LAN switching fabric interfaces to pseudo-ports, map pseudo-ports to WAN interfaces, and transmit LAN fabric datagrams received at the LAN switching fabric physical interface from the WAN physical interface via a mapped pseudo-port and a corresponding WAN interface.

The supersonic ejector utilized for cooling includes a cooling extension axially extending the discharge slot from the throat of the primary stream and is contoured to accelerate primary stream, to direct the primary stream to flow parallel to the secondary stream and match the static pressures of both streams and to ensure that the expansion shocks are upstream of the discharge slot. This supersonic ejector is utilized in one instance for cooling purposes in a two-dimensional vectoring nozzle of a gas turbine engine powering aircraft.

Cooling of the hot surfaces of the exhaust nozzle of a fan jet engine and purging of the nacelle is attained by a booster pump mounted in exhaust nozzle structure and the booster pump having an ejector driven by localized fan air existing in the engine cooling path extracted from the fan of the engine for pumping nacelle air and mixing the egressing fluid in a mixing chamber and diffuser disposed in fluid communication with booster pump which is then dumped into a plenum within the exhaust nozzle structure for feeding film cooling holes formed in the hot surfaces for laying a blanket of cooling air along the gas path surface of the exhaust nozzle.
