Abstract: Presented herein are techniques to facilitate dynamic negotiation and compression of Packet Forwarding Control Protocol (PFCP) messages in a mobile networking environment. In one example, a method includes identifying, by a function, a negotiated compression algorithm to utilize for compressing one or more Packet Forwarding Control Protocol (PFCP) messages; determining whether a payload for a particular PFCP message is to be compressed based on at least one of system resources of the function and a size of the payload; based on determining that the payload is to be compressed, compressing the payload utilizing the negotiated compression algorithm to generate a compressed PFCP message; and setting a compression indication in a header of the compressed PFCP message.

Abstract: In an apparatus for cutting a work by an abrasive water jet containing abrasive particles, an abrasive suspension such that abrasive particles with an average size of up to about 100 microns are held in suspension in water is supplied to a jet nozzle assembly in which the abrasive suspension is induced by a high pressure ejected water and directed against the work. The ejected water is passed through an ejected water passageway to which is connected an abrasive water orifice of an abrasive water nozzle tip. The abrasive water orifice has an upstream tapered portion the diameter of which gradually increases toward an upstream opening at which the abrasive water orifice is connected smoothly to the downstream end of the ejected water passageway, whereby the flow of ejected water is streamlined.

Abstract: For cutting sheet metal or other work by means of a jet of water containing abrasive particles, an abrasive water jet nozzle assembly is provided to which there are separately supplied highly pressurized water and an abrasive suspension. The abrasive suspension is such that abrasive particles with an average size of up to 100 microns are held in suspension in water. The abrasive suspension is introduced into the ejected water by virtue of a partial vacuum created in the nozzle assembly by the pressurized water. The nozzle assembly directs the resulting mixture as an abrasive water jet against the work for cutting thereof. Preferably, the abrasive water jet is recovered for recirculation back to the nozzle assembly as an abrasive suspension of controlled abrasive concentration. Various constructions of the nozzle assembly and various recovery systems are also disclosed.
