Abstract: Techniques for devices in autonomous systems to utilize a protocol, such as a Border Gateway Protocol (BGP), to signal intent to instantiate services for establishing connections between the devices. For instance, first device(s) in a first autonomous system (AS) may determine to establish a connection with a second AS. The first device(s) may encode a service key into an Internet Protocol (IP) address where the service key indicates a service that is to be provisioned on second device(s) in the second AS. The first device(s) system may then advertise the IP address host-route using BGP, and the second device(s) may receive the BGP advertisement. The second device(s) may decode the service key from the IP address, and provision the service to establish the connection between the autonomous systems. Thus, the devices in may leverage existing protocols to signal intent to instantiate services and establish connections between autonomous systems.

Abstract: The present invention relates to a laser cutting technology for cutting and separating thin substrates of transparent materials, for example to cutting of display glass compositions mainly used for production of Thin Film Transistors (TFT) devices. The described laser process can be used to make straight cuts, for example at a speed of >0.25 m/sec, to cut sharp radii outer corners (<1 mm), and to create arbitrary curved shapes including forming interior holes and slots. A method of laser processing an alkaline earth boro-aluminosilicate glass composite workpiece includes focusing a pulsed laser beam into a focal line. The pulsed laser produces pulse bursts with 5-20 pulses per pulse burst and pulse burst energy of 300-600 micro Joules per burst. The focal line is directed into the glass composite workpiece, generating induced absorption within the material.
