network elements.
Operators will only be able to capitalize on these opportunities if the transport network is capable of handling the explosion of data traffic and delivering those low latency services, meeting the stringent 5G Service Level Agreements (SLAs).Traditionally, networks have been built in a layered approach where each layer is designed individually and operated within its own technology lifecycle.
The white paper is a pre-cursor to Broadband Forum’s transport network architecture, detailing the capabilities operators need to deliver on the promise of 5G 5G … The transport network consists of SDN controllers and underlying forwarding nodes.
It requires low-latency transport between certain elements and different amounts of bandwidth depending on the communicating elements. 5G Transport A Cost-Effective, Scalable Network Architecture Approach Introduction According to a recent Cisco Annual Internet Report (AIR), more than 70 percent of the global population – approximately 5.7 billion people – will have mobile connectivity by the year 2023.This connectivity includes 2G, 3G, 4G, and 5G…

According to a recent Cisco Annual Internet Report (AIR), more than 70 percent of the global population – approximately 5.7 billion people – will have mobile connectivity by the year 2023.This connectivity includes 2G, 3G, 4G, and 5G. This strategy for the synchronization of radio equipment will likely revolutionize the mobile network and underpin the worldwide adoption of 5G technologies.Provides faster, simpler automated operations, provisioning, and management, which lowers operating expenses.An advanced routing platform powered by Cisco IOS XR software. “5G is driving mobile operators to take a holistic approach to transport network planning.
For example, 5G backhaul baseband interfaces will need 10 Gbps capacity and need to scale efficiently up to 100Gbps.This will be realized by the transport architecture being developed which will provide the necessary standard interfaces, requirements, and modeling to realize this automation.According to Broadband Forum, to meet this demand, the transport network needs to evolve to enable operators to provide the needed capabilities for 5G in a practical and effective manner. These advancements include:5G promises faster data speeds, higher capacity, and low latency enabling new services, presenting the mobile industry with unprecedented revenue growth opportunities.
Current network architecture needs to evolve to meet the needs of the wide variety of use cases enabled by 5G technology. They provide the foundation for revolutionary new 5G applications such as pervasive mobile broadband, massive IoT, tactile Internet, smart cities, and virtual reality.Learn how Rakuten Mobile Network Inc. is virtualizing its entire network to offer consumer mobile, NB-IoT, and fixed wireless connections.Helps shift compute loads to the edge with multi-access edge compute (MEC).Offers freedom from proprietary interfaces using Common Public Radio Interface (CPRI) and improved archiectural flexibility for radio placement (RRH, DU, and CU) with no radio vendor lock-in.As 5G new radio (NR) standardization progresses, transport networks must be re-architected to support 5G applications at scale.
Legacy transport systems need to be upgraded and backhaul systems must meet a suite of new demands to ensure superior RAN performance and maintain low total cost of ownership.5G requires a highly scalable and future oriented network architecture — including intelligent, coordinated, automation of the RAN, mobile core, and transport networks — to enable deployment and operation of new revenue generating services, the company said.5G backhaul systems need to address increased capacity and greater interface density requirements.
“Technology and application performance requirements will lead to a future transport network that looks very different. Based on our investigations, we provide guidelines fo r the development of the 5G transport network architecture. 5G is driving mobile operators to take a holistic approach to transport network architecture, according to new research from the Broadband Forum. “Technology and application performance requirements will lead to a future transport network that looks very different. Broadband Forum Motivates 5G Transport Network Architecture and Requirements. The standard will leverage IPv6, segment routing, MPLS, Ethernet VPN (EVPN) and other technologies to enable effective and scalable transport networks to support operator 5G deployments, in conjunction with LTE and 4G operations.Broadband Forum is an open, non-profit industry organization composed of the industry's leading broadband operators, vendors, thought leaders who are shaping the future of broadband, and observers who closely track our progress. "While the initial focus in 5G is on potential use cases and the radio technology itself, 5G cannot exist without a transport network to support it," said Joel Halpern, Editor of the 5G Network Architecture white paper, of Ericsson (News - Alert).
