WebThey use a one-shot performance metric—CCT (coflow completion time), which cannot continuously reflect the staleness of the output results for a streaming application.To this end, we propose a new performance metric—coflow age (CA), for coflows generated by distributed streaming applications.

Webtime, Figure 2 compares four different schedules. Per-flow fairness (Figure 2a) ensures max-min fairness among flows in each link. However, fairness among flows of even the same coflow can in-crease CCT [15]. WSS (Figure 2c) – the optimal algorithm in ho-mogeneous networks – is up to 1.5× faster than per-flow fairness WebJul 6, 2024 · Fair Coflow Scheduling without Prior Knowledge Abstract: Coflow scheduling improves the networking performance at the application level in datacenters. Ideally, a coflow scheduler should provide tenants with isolation guarantees to achieve predictable networking performance. WebRecently, coflow has been proposed as a new abstraction to capture the communication patterns in a rich set of data parallel applications in data centers. Coflows effectively model the application-level semantics of network resource usage, so high-level optimization goals, such as reducing the transfer latency of applications, can be better ... trudy crooks
