What is a high-performance, multi-service switching technology that is used in packet data networks that enables Layer 3 devices such as routers to establish and manage network traffic? This technology has succeeded other protocols as the dominate private WAN service, and while expensive, it has good reliability (up to 99.99%). Rather than long network addresses, it uses short path labels for route efficiency.
