摘要：An enhanced-internet network that provides ultra-low-latency guaranteed-rate (GR) communications forcloud services is proposed. The network supports traffic flows receive low-jitter GR service over virtual-circuitswitched(VCS) connections with negligible buffering and queueing delays, up to 100% link utilization, deterministicend-to-end quality-of-service (Qos) guarantees, and improved energy efficiency. End-to-end delays are effectivelyreduced to the fiber “time of flight.” A new router scheduling problem called the bounded normalized-jitter integerprogrammingproblem is formulated. A fast polynomial-time approximate solution is presented, allowing TDM-basedrouter schedules to be computed in microseconds. We establish that all admissible traffic demands in any packetswitchednetwork can be simultaneously satisfied with GR-VCS connections, with minimal buffering. Each router canuse two periodic TDM-based schedules to support GR-VCS connections, which are updated automatically when therouter’s traffic rate matrix changes. The design of a silicon-photonics all-optical packet switch with minimal bufferingis presented. The enhanced-internet can:1) reduce router buffer requirements by factors of ≥1000; 2) increase theinternet’s aggregate capacity; 3) lower the internet’s capital and operating costs; 4) lower greenhouse gas emissionsthrough improved energy efficiency.
