In data center networks (DCN), large scale flows produced by parallel computing frameworks form many coflows semantically. Most inter-coflow schedulers only focus on the remaining data of coflows and attempt to mimic Shortest Job First (SJF). However, a coflow may consist of multiple stages, where a coflow has different amounts of data to transmit. In this paper, we consider the Multi-stage Inter-Coflow...
The lack of optical buffer is still one of the main problems that hinder the development of all optical network. The current works on this topic mainly focus on emulating optical buffers with fiber delay line (FDL). Recent advances have shown the feasibility of emulating many kinds of optical buffers, such as the First In First Out (FIFO) buffer, priority buffer, etc. The Last In First Out (LIFO)...
The lack of optical buffer is still one of the main problems that hinder the development of all optical network. The current works on this topic mainly focus on the emulation of optical buffers by using bufferless switch fabric and fiber delay line (SDL). Recent advances have shown the feasibility of emulating many kinds of optical buffers, such as first in first out (FIFO) buffer, priority buffer...
Shared-memory optical packet (SMOP) switch architecture is very promising for significantly reducing the amount of required optical memory, which is typically constructed from fiber delay lines (FDLs). The current reservation-based scheduling algorithms for SMOP switches can effectively utilize the FDLs and achieve a low packet loss rate by simply reserving the departure time for each arrival packet...
