Application Guide: Carrier Ethernet SLAs

Service delivery and service assurance support tools


The growth in popularity of Business Ethernet services is closely linked to the level of maturity Ethernet technology has reached, enabling carriers to deliver and audit hard service level agreement (SLA) guarantees that satisfy exacting requirements from enterprise users. Carriers and service providers deploying Business Ethernet VPNs must be prepared to ensure measurable and enforceable SLAs that detail commitments for user traffic handling, availability and performance guarantees, among others.

Focusing on a Layer 2 VPN use case, the Carrier Ethernet SLA Support Tools application guide reviews the various service delivery and service assurance support mechanisms that carriers and telecom providers can utilize to ensure service reliability, measurable KPIs (key performance indicators) and SLA commitments.
