Abstract

We present the first online algorithm with a polylogarithmic competitive ratio for the problem of online routing of packets in unidirectional grids. The goal is to maximize the throughput, i.e., the number of delivered packets. Our online algorithm is deterministic, centralized, handles packets with deadlines, allows bounded buffers, uses adaptive routing, and may drop packets before they reach their destination. All previous online algorithms for packet routing on a unidirectional line with polylogarithmic competitive ratios are randomized [AZ05, AKK09, EM10]. Our algorithm is the first deterministic online algorithm with a polylogarithmic competitive ratio.
