What has been missing is the benefits of cloud technologies to the part of the network that serves as the on-ramp to the cloud: the metro edge. Ensemble Open Service Architecture™ (Ensemble OSA) bridges that gap, allowing service providers to apply cloud technologies and principles to build and deliver services across the metro edge by uniting connect, compute and store.
Cloud services for connect, compute and storage represent a business opportunity for CSPs and will drive them towards service-enabling smart networks. Service delivery now requires a level of automation not possible with current proprietary network architectures. New solutions will be critical to enable service assurance and service creation. Two important new capabilities are the softwaredefined network (SDN) -- a new framework for open, programmable interfaces that can enable a high degree of automation in provisioning services – and network function virtualization (NFV) – a technique for creating network services using commercial off-the-shelf hardware rather than purposebuilt appliances.
The communications industry is entering an exciting new era with the emergence of software-defined networking (SDN). Over the past year, we have seen dramatically increased carrier interest in applying SDN architectural concepts and marrying SDN, carrier Ethernet 2.0, access and metro technologies to unleash the capabilities of the network in unprecedented ways to support cloud and other next-generation business, residential and mobile services.
This whitpaper from Heavy Reading is designed to shed light on how operators can take advantage of emerging SDN solutions to build and operate more efficient and service-friendly metro networks today while putting in place a software-driven infrastructure that will enable them to support a vast array of innovative and differentiating services and applications in the future.
The virtualized services model of cloud computing has significant implications on today's network, and how it is evolving to the network of tomorrow. The network impact of cloud computing is in fact so significant that any discussion on cloud computing should also include cloud networking. Without the network, there could be no cloud. Since Carrier Ethernet is the optimal networking solution for connection oriented services and the optimal Layer-2 for IP services, is also the optimal solution for cloud computing.
Service providers increasingly see their off-net success determined by their ability to leverage wholesale Ethernet and E-Access Services. E-Access allows service providers to grow their footprint, shorten turn-up time and expand service offerings. But what are the success factors that the early adopters of wholesale E-Access servcies have learned?
The requirement for 100’s of Mb per cell tower for 3G and 4G services is good news for backhaul providers who stand to gain new business from delivering that bandwidth. However, it also presents fundamental business challenges for the mobile backhaul provider. Mobile backhaul networks must have the scalability to handle 3G and 4G bandwidth growth. Service providers focused on delivering maximum scalability are already architecting 10GigE solutions for mobile backhaul.
Enterprise access networks must be architected with Carrier Ethernet solutions to deliver 99.999% availability, flow-level SLA management, end-end OAM, wire-speed performance and 50ms protection switching. These networks must also cost significantly less than SONET/SDH, enable massive Ethernet scaling and continue to support high performance DS1/E1 for legacy voice, data and private line applications.
Mobile backhaul and enterprise access networks must be architected with Carrier Ethernet solutions to deliver 99.999% availability, 50ms protection switching, flow-level SLA management, end-end OAM, performance and resiliency. These networks must also cost significantly less than SONET/SDH, enable massive Ethernet scaling and continue to support highperformance DS1 for 2G mobile and private line applications.
Ethernet Mobile Backhaul scores a perfect 10 with 10x the bandwidth at 1/10th the cost. Tap into a better way to backhaul the rising tide of mobile data with resilient, reliable and flexible Ethernet backhaul solutions from Overture. Don’t settle for less than great.
This white paper explores the issues that mobile operators face as they move from T1/E1 backhaul to Ethernet backhaul and introduces BFP (Big Flexible Pipe), a major technology innovation in ultra efficient transport of native TDM voice, native Ethernet and T1/E1 quality timing. The paper’s content will illustrate how BFP delivers T1/E1 quality voice and timing performance with greater resiliency and reliability than T1/E1s while delivering 10x More Bandwidth at 1/10th the cost over bonded copper pairs.
ITU G.8032 is a technology game-changer – delivering the cost and Ethernet services advantages of a Carrier Ethernet infrastructure with standardsbased 50ms protection switching.
Customers require 50ms protection switching for their high-performance Carrier Ethernet applications. Overture Networks developed a G.8032 Ethernet Ring solution to not only meet, but to significantly beat this requirement. Overture configured a battery of real-world network scenarios to measure protection switching time. The results provide proof that Overture's G.8032 solution sets a new standard for protection switching.
The Overture 4200/4300 Series is designed from the ground up for carrier infrastructure applications...delivering the 99.999% availability required by carriers.
The "Selling Mid-Band Ethernet Services" handbook is a guide for Service Providers on how to sell and position Mid-Band Services. This handbook highlights different opportunities available with the implementation of Mid-Band Ethernet services across industries as diverse as finance and health care or retail and legal services.
The “Mid-Band Ethernet Spectral Compatibility Handbook” is designed to help Carriers and Service Providers better understand the spectral compatibility of symmetric services. There are a number of options for delivering symmetric services – T1s, HDSL, SHDSL, enhanced-SHDSL, and VDSL2 to name a few. In this handbook we mostly focus on the two newest technologies for symmetric services – enhanced SHDSL and VDSL2 – to see how they compare in realistic deployment environments.
The “Mid-Band Ethernet Services Handbook” is designed to help Carriers and Service Providers with service definition to significantly grow their top-line revenue through the deployment of Mid-Band Ethernet Services, hitting the service sweet spot between 2 and 20Mbps. Mid-Band Ethernet is an emerging market that will double the addressable Metro Ethernet port forecast over the next 5 years.
Service providers today find a growing number of their edge routers have reached retirement age as the combined factors of diminished product support, lack of spares, high operational costs and missing features take their toll. But what is the best replacement strategy for some of these legacy edge routers?
Driven by their low cost, affordable bandwidth and their scalability, Ethernet services are growing rapidly and are also now reaching critical market mass. Two major factors are still preventing a complete adoption of Carrier Ethernet: service availability and service reliability. Needless to say, the latter strongly influences the former. Indeed, without any means of measuring network performance, Service Level Agreements (SLA) cannot be guaranteed from one end to the other end. Network performance, and SLA verification in particular, is even more important when considering the growth of demand in IP-based services such as Voice over IP (VoIP), Video over IP and Internet Protocol Television (IPTV) which require very low latency (delay) and jitter (delay variation). Without SLA verification tools, there is no good way to guarantee an end-to-end Quality of Service (QoS).
In August 2010, Carrier Ethernet News (www.CarrierEthernetNews.com) conducted a survey of its service provider readers to understand the features and capabilities they believed important in differentiating their services from their competitors. 110 representatives from service providers responded to the survey. This document describes the results of this survey and its key findings.
