44 Advancements in Control-Layer Technologies Customer-facing SDN/NFV (AT&T Network on Demand) APPLICATION 44
45 Carrier Use Cases AT&T AT&T Network on Demand USE CASES AT&T Network on Demand is the first of its kind software-defined networking solution in the U.S. It makes network management easier than ever with an online self-service portal. Business customers can now easily add or change services, scale bandwidth to meet their changing needs and manage their network all in near real time. This translates into time savings and less complexity for companies of all sizes. AT&T Network on Demand is our vision for the network of the future. Using the latest technologies and open network principles, we ve created a smart, cloud-like network to more effectively customer needs a global first at this scale. We began trials of Network on Demand in September 2014 and have since expanded to over 100 U.S. cities. AT&T Switched Ethernet Service sm is the first Network on Demand enabled service available; more services will be added later this year. Some of the specific benefits of Network on Demand include: Intuitive web portal offers immediate click-through ordering and improved network control Scale bandwidth speeds in near real time instead of hours or days Installation times are scaled down from weeks to days Excerpts from the AT&T Website available at: ETC Group, LLC 8/19/
46 Carrier Use Cases AT&T AT&T Universal CPE USE CASES AT&T will soon be launching Virtual Managed Services with a new virtualized appliance: Universal Customer Premises Equipment (ucpe). Utilizing network function virtualization (NFV) technology, ucpe network appliances can be run as software on a virtual machine. Instead of installing a physical router, a customer could turn up a software-based virtual router in near real-time. Not only does the Universal CPE afford increased speed but, for the first time, the ability to run multiple functions simultaneously. The unique open design enables multiple virtual network functions (VNFs) to run concurrently. For example, if a customer wants a router and a WAN accelerator, they can activate both of those functions on the same physical box. Customers can soon enjoy the speed and control of the AT&T Universal CPE. We will soon begin beta trials and later expand with additional ucpe form factors and virtual network functions, as well as additional Virtual Managed Services offerings in the cloud. Excerpts from the AT&T Website, available at: ETC Group, LLC 46
47 Carrier Use Cases AT&T AT&T Domain 2.0 USE CASES AT&T regularly reviews and revises business and technology approaches. Significant emerging technologies and business drivers have encouraged the company to reassess desired future network technology, operations methods, and sourcing approaches in an effort called Domain 2.0. In summary, the major aspects of AT&T s Domain 2.0 architecture are: Open Provide APIs, enable better participation of third parties, and improve visibility. Increase the number of suppliers and partners AT&T can do business with. Simplify Weed out complexity from services and operations; support more nimble business models. Scale Meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations. Improve business efficiency in capital and operations. Excerpts from the AT&T Domain 2.0 Whitepaper, available at: ETC Group, LLC 47
48 Carrier Use Cases AT&T AT&T Domain 2.0 USE CASES Migrating AT&T businesses to a multi-service, multi-tenant platform implies replacing or augmenting existing network elements which today are typically integrated to perform a single function. The replacement technology consists of a substrate of networking capability, often called Network Function Virtualization Infrastructure (NFVI) or simply infrastructure that is capable of being directed with software and Software Defined Networking (SDN) protocols to perform a broad variety of network functions and services. This infrastructure is expected to be comprised of several types of substrate. The most typical type of substrate being servers that support NFV, followed by packet forwarding capabilities based on merchant silicon, which we often call white boxes. AT&T seeks to engage in a transformation of network technology, operations, infrastructure, software, and APIs in a way that provides greater value to customers and application development partners. The result will be a cloud-centric networked capability that can support varied workloads along with flexible business models.
