Новости Перспективы развития технологий «последней мили»: Объединенный доступ MPLS и Carrier Ethernet для увеличения доходов
26.04.2012

В ближайшем обозримом будущем Carrier Ethernet (CE) несомненно будет доминировать среди технологий «последней мили», к чему располагают не только растущие требования пользователей по оптимизацию работы сетей, но и практический взгляд операторов на бизнес, где важно максимизировать доли рынка и доход от сетей. Тим Кван (Tim Kwun), вице-президент Raisecom Technology, высказывает свое профессиональное мнение о развитии технологии Carrier Ethernet в близжайшем будущем


Prospects For “Last Mile” Access Technology


The advent of Carrier Ethernet has pushed forward the development of telecom services, network convergence and network transformation. For the trend of packet transport network, Carriers Ethernet plays an important role. Tim Kwun, the vice president of Raisecom Technology, has given his personal observation about Carriers Ethernet technology development, relevant application in this field and prospect analysis according to years of experience.

"Carriers Ethernet (CE) is definitely dominant for the last mile access technology in coming days, as it is not only being pushed by intrinsic customer demands on optimizing ubiquitous network experiences, but also by practical Carrier business cogitations on maximizing market shares and revenue generation. 

 

As a customer, demands on easy access, committed bandwidth, improved security and assured scalability are all required and ever increasing during on the go daily work and life. As a Carrier, in order to retain a leading position and keep the revenue growing in face of competitive market prices of bandwidth, it is forced to give up legacy technology for access, but merge or shift current networks to Ethernet basis.  

 

Over years of development, today’s Ethernet is no similar than it was before. High bandwidth and economic infrastructure are no longer the only two advantages, it also capable to deliver customized bandwidth, reliable resilience, and guaranteed SLA for diversified services with the extensive introduction of new technologies and standards, such as H-QoS, ITU-T G.8031/2, IEEE802.1ag, ITU-T Y.1731, SycE and IEEE1588v2. 

 

Moreover, from the point of conveniently configuring and maintaining CE networks, we are observing efforts from the industry and organizations in driving hard from MEF defined CE1.0, which just standardized fundamental services, to CE2.0, which was officially announced on February 23 this year and declares more service types in a bigger scope. 

 

It is also foreseeable that the coming trends of automated service configurations will be portrayed in CE 3.0. Although the whole concept still needs to be commented and requires more real-life practice and experience, the future for dominant last mile access technology and prospect is clear.

 

Facilitated with all above visions and efforts, there are two application areas shall worth more attentions. One is the enterprise market, where growing demands are raised to catch up with intelligent, automated and electronic trends in external and internal communications, management and operations, such as wholesale arrangement, data center, VPN services and cloud computing. The other is LTE, which enables a fusion of mobile experience including online gaming, video, e-class, remote-monitoring, and info surfing via Ethernet access to eNodeB.

 

Different from public Internet business encountering a decrease of margin even with an increased subscriber base, it is no doubt that business connection and mobility services are boosters of Carrier’s fiscal reports.

 

To accelerating the two most promising business, it turns that MPLS core plus CE access is one best choice leveraging both cost and target. In the core network, MPLS technology is typically implemented in mesh topology to provide guaranteed services with full protection and sustainable bandwidth capacity. In last mile, CE is generally preferred and configured as extensions of committed services from MPLS edges to the demarcation point."
