The Scalable Address Resolution Protocol for Large Data Centers

Overview

RFC 7586, “The Scalable Address Resolution Protocol for Large Data Centers”, is an Experimental document published in June 2015 by Y. Nachum, L. Dunbar, I. Yerushalmi, T. Mizrahi. The canonical text is published by the RFC Editor.

Abstract

This document introduces the Scalable Address Resolution Protocol (SARP), an architecture that uses proxy gateways to scale large data center networks. SARP is based on fast proxies that significantly reduce switches' Filtering Database (FDB) table sizes and reduce impact of ARP and Neighbor Discovery (ND) on network elements in an environment where hosts within one subnet (or VLAN) can spread over various locations. SARP is targeted for massive data centers with a significant number of Virtual Machines (VMs) that can move across various physical locations.
