The Scalable Address Resolution Protocol for Large Data Centers
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.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
