This MEF Best Practices document describes ways for the Backhaul Provider to optimize the use of Mobile Backhaul bandwidth resulting in considerable cost savings as well as improving application-specific quality of service. The paper describes both Single CoS and Multi-CoS Wireless backhaul use cases. It provides 16 implementation recommendations for Multi-CoS mobile backhaul together with the rationale and implications of those choices in various scenarios. The paper also addresses the top challenges that Mobile Operators and Backhaul Providers face in moving to Multi-CoS Wireless Backhaul.
The enterprise Information and Communications Technology landscape is constantly changing. New IP based voice and video services, continue to add pressure on the WAN to deliver increased bandwidth and enhanced performance. On the WAN front, legacy technologies such as FR and ATM are being grand fathered by many service providers. TDM based connectivity such as DSn and OCn do not provide the operation flexibility expected by the modern enterprise. As ICT managers look for solutions, MEF defined, Carrier Ethernet services have emerged as an attractive alternative to provide those enterprises with a best of breed cost effective solution. The goal of this MEF positioning paper is to help enterprise decision makers better understand the role that Carrier Ethernet services can play in a business environment.
This paper introduces the concept of delivering private cloud services via Carrier Ethernet wide area networks and services. Its intention is to educate and initiate a dialog between the cloud industry’s stakeholders (enterprise users, cloud service providers, standards development organizations and cloud forums). The paper discusses the reasons why this is an important and beneficial development for stakeholders: generating new revenue opportunities while overcoming the many well-documented issues related to cloud service delivery to the Enterprise via the Internet. This is the first deliverable of the MEF’s very active Cloud Project that includes expansion of CE 2.0 Ethernet service attributes to embrace the dynamic, on-demand nature of cloud services.
Mobile Backhaul refers to the network between Base Station sites and Network Controller/Gateway sites for all generations of Mobile Technologies. This document is based upon the MEF22.x Mobile Backhaul Implementation Agreement Technical Specification , which identifies the requirements for MEF Carrier Ethernet Services and MEF External Interfaces for use in Mobile Backhaul networks. Where possible, it specifies frequency and phase synchronization requirements for packet based synchronization methods and ITU-T Synchronous Ethernet (SyncE).
Historically, Mobile Operators obtained connectivity between their Cell Sites and their on-net Aggregation Sites primarily by leasing TDM circuits from third party Access Providers. Increasingly, Carrier Ethernet is the target solution for mobile backhaul with the Mobile Operator leasing Ethernet Virtual Connections from the Access Provider. Today, in the vast majority of cases, these EVCs are running a single Class of Service. While the use of Single-CoS EVCs is a way to get started, the MEF believes that the use of Multi-CoS EVCs for mobile backhaul is a much superior practice.
This paper compares Single CoS backhaul to Multi-CoS backhaul, concluding that. Multi-CoS mobile backhaul results in substantial cost savings and that this lower cost Multi-CoS solution will result in equivalent or better quality than the Single-CoS solution.
Customers increasingly want more bandwidth and better service quality to meet their application needs. Carrier Ethernet services are frequently the best selection to meet these requirements. This white paper provides an overview of how modern Microwave technology provides an efficient complement to copper and fiber in the access network.
Globalization, virtualization, and mobile computing drive a seemingly insatiable demand for bandwidth, and only Carrier Ethernet efficiently scales up to meet this demand. Customers seeking high performance business Ethernet services can now easily purchase faster Ethernet connections at 10 Mbit/s to 1 Gbit/s and beyond. But sometimes users believe they are receiving lower throughput than they expected. This MEF white paper presents an overview of the more common factors affecting Carrier Ethernet throughput, provides some pointers for getting more performance from higher layer protocols, and shows how to measure bandwidth throughput of a Carrier Ethernet service.
Implementing Standardized Ethernet Interconnects for Carrier Ethernet Services. The goal of this document is to outline the activities needed for Service Providers to implement the interconnection of autonomous Carrier Ethernet networks to enable standardized and streamlined delivery of MEF-certified Carrier Ethernet services with global end-to-end Class of Service, management and protection. Readers are introduced to the various implementation phases of Qualifying, Contracting, Ordering, Provisioning, Billing, and Assuring for Ethernet interconnections. Guidelines are provided to assist parties implementing the Ethernet interconnect at each phase.
This whitepaper provides a comprehensive technical overview of Ethernet services, based on the work of the Metro Ethernet Forum (MEF) Technical Committee. The paper is intended to help buyers and users of Ethernet services understand the various types and characteristics of Ethernet services, and to help service providers clearly communicate their service capabilities.
This paper provides an introduction to the various applications considered to be most dominant and fastest growing in the access networks. It also discusses the benefits of various access technologies available to support service providers offering an Ethernet service, as well as to subscribers to those services.
This paper provides an introduction to Circuit Emulation Services over Ethernet (CESoE) enabling the support of synchronous services such as T1/E1 over an asynchronous Ethernet infrastructure. The paper discusses the benefits of CESoE to service providers offering Ethernet access services, as well as to subscribers to those services in various applications. Finally, the paper discusses the current activities of MEF in standardizing and promoting CESoE.
This paper provides a comprehensive technical overview of bandwidth profiles for Ethernet services, based on the work (as of October 2003) of the Metro Ethernet Forum (MEF) Technical Committee. The paper is intended to help buyers, users, providers of Ethernet services and equipment/semiconductor vendors understand the various types, characteristics and usage of bandwidth profiles as defined by the MEF.
