High-Performance Routing With Multipathing and Path Diversity in Ethernet and HPC Networks
نویسندگان
چکیده
The recent line of research into topology design focuses on lowering network diameter. Many low-diameter topologies such as Slim Fly or Jellyfish that substantially reduce cost, power consumption, and latency have been proposed. A key challenge in realizing the benefits these is routing. On one hand, networks provide shorter path lengths than established Clos torus, leading to performance improvements. other number shortest paths between each pair endpoints much smaller Clos, but there a large non-minimal router pairs. This hampers even makes it impossible use multipath routing schemes ECMP. In this article, facilitate high-performance modern networks, we analyze existing protocols architectures, focusing how well they exploit diversity minimal paths. We first develop taxonomy different forms support for multipathing overall diversity. Then, Among others, consider with both non-shortest paths, disjoint enabling adaptivity. To address ongoing convergence HPC “Big Data” domains, developed systems data centers general clusters. Thus, cover architectures based Ethernet, InfiniBand, Myrinet. Our review will foster developing future supercomputers centers.

15 صفحه اولAnalysing GeoPath diversity and improving routing performance in optical networks
With the increasing frequency of natural disasters and intentional attacks that challenge telecommunication networks, vulnerability to cascading and regional-correlated challenges is escalating. Given the high complexity and large traffic load of optical networks, these correlated challenges cause substantial damage to reliable network communication. In this paper, we propose a network vulnerab...
متن کاملAll-Path Routing Protocols: Analysis of Scalability and Load Balancing Capabilities for Ethernet Networks
This paper presents a scalability and load balancing study of the All-Path protocols, a family of distributed switching protocols based on path exploration. ARP-Path is the main protocol and it explores every possible path reaching from source to destination by using ARP messages, selecting the lowest latency path. Flow-Path and Bridge-Path are respectively the flow-based and bridge-based versi...
