Abstract
The trend toward cloudification of communication networks and services, with user data and applications stored and processed in data centers, pushes the limits of current Data Center Networks (DCNs), requiring improved scalability, resiliency, and performance. Here we consider a DCN forwarding approach based on software-defined addressing (SDA), which embeds semantics in the Medium Access Control (MAC) address and thereby enables new forwarding processes. This work presents Flow-Zone Switching (FZS), a loop-free location-based source-routing solution that eliminates the need for forwarding tables by embedding routing instructions and flow identifiers directly in the flow-zone software-defined address. FZS speeds the forwarding process, increasing the throughput and reducing the latency of QoS-sensitive flows while reducing the capital and operational costs of switching. This paper presents details of FZS and a performance evaluation within a complete DCN.
Highlights
Data center demand has increased profoundly in the last decade, driven largely by the success of the cloud computing paradigm
Flow-Zone Switching (FZS) uses the octets of the Medium Access Control (MAC) address to encode an address format identifier to identify the type of frame, two or three zone identifiers to locate the servers and switches in the typical topology, and one or more flow IDs to identify the traffic flows or flow types, allowing per-flow management with fine granularity, complex Quality of Service (QoS) management, and advanced resource allocation
The FZS routing method minimizes the state in switches by embedding the routing instructions directly in the MAC addresses, completely removing the need for forwarding tables
Summary
Data center demand has increased profoundly in the last decade, driven largely by the success of the cloud computing paradigm. FZS minimizes the state in switches and, by embedding the routing instructions directly in the MAC addresses, can completely remove the need for forwarding tables. FZS aims to enhance the state of the art by completely removing the lookup tables and at the same time providing fine granularity for specific flow management, boosting the DCN performance while reducing its cost. Each frame contains the path towards its source, as well as to the destination, with separate source-based and destination-based flow fields, without the intervention of any other protocol or mechanism This means, for example, that the destination can directly learn the Layer 2 flow-zone address associated with the IP address of a received frame and can respond to that frame without the need to consult an external ARP server.
