Network Virtualization using Shortest Path Bridging and IP/SPB

Get the White Paper

November 7th, 2011

By Avaya

This White Paper discusses the benefits and applicability of the IEEE 802.1aq Shortest Path Bridging (SPB) protocol, which is augmented with sophisticated Layer 3 routing capabilities. The use of SPB and the value to solve virtualization of today’s network connectivity in the enterprise campus as well as the data center are covered.

This document is intended for technically savvy network managers as well as network architects who are faced with:
• Reducing time to service requirements
• Less tolerance for network down time
• Network Virtualization requirements for Layer 2 (VLAN-extensions) and Layer 3 (VRF-extensions)
• Server Virtualization needs in data center deployments requiring a large set of Layer 2 connections (VLANs)
• Traffic separation requirements in campus deployments for security purposes as well as robustness considerations (i.e., contractors for maintenance reasons needing access to their equipment or guest access needs)
• Multi-tenant applications such as airports, governments or any other network with multiple discrete (legal) entities that require traffic separation
