First Standardized Multi-CoS
Defining Specification: MEF 23.1 Class of Service Phase 2
• Scope – 3 Classes of Service (more than 3 classes may be specified)– 20+ application types, 4 distance related “Performance Tiers”– Enhanced QoS metrics: adds Mean Frame Delay and Frame Delay Range, Availability, etc. to Inter Frame Delay, Inter-
Frame Delay Variation, Frame Loss Ratio
• Standardizes CoS Performance Objectives (CPOs)– Draws on the above to define standardized CoS Performance Objectives (CPOs)– New MEF MBH specification draws on MEF 23.1: 4 CoS, etc
• Globally Engineered Networking– Defines how service attributes, CoS are mapped across provider boundaries – Preserves the integrity of services regionally, nationally and globally

Cloud Service Delivery Challenges
• Today, Internet is predominant WAN to deliver cloud services– Surprising, little attention paid to it by the Cloud Community
• Larger Enterprises hesitant to move mission-critical applications to the cloud when delivered via the Internet
The WAN is critical for cloud service performance (SLAs)
Cloud Service Delivery Challenges over the Internet
• Security Vulnerabilities• Performance• Data Governance• Regulatory Compliance

Features and Impact of CE 2.0 for MBH
Network Impact 10 Mbps to 100 Gbps TDM Ethernet 4G/LTE Multi-CoS brings better QoS &
efficient use of bandwidth Blueprint for packet and network-
based synch in 4G/LTE networks Enables resilient connections to
hub sites and major cell sites OAM reduces support costs with
fault sectionalization, performance measurement
• Migration:2G, 3G, 4G/LTE• Multiple classes of service • Synchronization• Resiliency• OAM
Features and Impact of CE 2.0 for MBH
Business Impact Affordable bandwidth vs. legacy
Meets escalating demand with reduced CapEx, OpEx
Standardized implementation Reduced development cost
Multi-CoS reduces CapEx for Access Providers, avoids over-provisioning
Migration guidance helps build and understand cost model
Resiliency reduces SLA risks OAM reduces support costs
• Migration:2G, 3G, 4G/LTE• Multiple classes of service • Synchronization• Resiliency• OAM
