摘要：
This paper presents guaranteed Latency Based Forwarding (gLBF), a solution that allows for the delivery of packets with end-to-end latency guarantees and that provides per-hop bounded latency with zero jitter. gLBF combines the benefits of earlier algorithms, Urgency-Based Scheduling and Cyclic Queuing and Forwarding, while avoiding their respective downsides. Specifically, gLBF does not need to maintain per-flow state at forwarding devices and does not require strict clock synchronization across the network. As a result, gLBF results in network deployments of significantly reduced complexity and lower cost than previous solutions.
