Abstract: Conventional internet routing is handled using routing protocols such as the Border Gateway Protocol (BGP). However, simple BGP does not account for latency, packet loss, or cost. To address this problem, smart routing systems that route traffic fast and in a cost-effective manner are implemented. In one approach, smart routing systems measure, compare, and analyze round-trip latencies and other metrics between a customer premises and one or more endpoints. Optimal inbound and outbound transit providers are selected for each endpoint based on these measurements. Other smart routing systems collect and analyze Real User Monitoring (RUM) data to predict latency performance of different content origins for serving data to a particular client based on the client's IP address and the content origins' IP addresses, which are ranked by performance. These rankings are used to steer traffic along lower latency paths by resolving Domain Name System (DNS) queries based on the performance associated with the IP addresses.

Abstract: The present invention is a method and system for reducing contamination in the resulting plasma of a weld produced by a fiber laser. The invention establishes the fiber laser in an optimal configuration for applying a high density beam to a weld material that eliminates spectral interference. The beam is applied in a narrow bandwidth of 1064 nm +/- 0.5 nm in one operative condition using an inert shielding gas, preferably argon, in a cross-flow or controlled environment around the welding region to prevent contamination of the plasma forming in the weld region. The method is optimized by determining and avoiding the emission spectrum for the fiber laser and the cover gas or gasses as well as any particular excitation spectra for the weld material. The system can utilize a single laser input, or can utilize multiple lasers joined by coupling means and utilizing a switch to select one or more of the fiber lasers.
