This paper presents an overview of the service and network management architecture of Lucent Technologies' CyberCarrier Solution. Businesses of all sizes and from all sectors are choosing to outsource large portions of their information technology (IT) operations to Internet‐based data centers that host application service providers (ASPs). Many network service providers (NSPs) have decided to become CyberCarrier service providers (CCSPs)—that is, they have decided to expand their businesses to include ASP data center hosting services. Managing these new ASP data center hosting services is one of the most urgent challenges encountered by a CCSP, and its solution is arguably critical to a CCSP's long‐term success. Although introducing ASP data center hosting services increases and diversifies a CCSP's revenue, it also significantly complicates the CCSP's management processes. This paper defines an abstract management functional architecture that divides the CCSP management problem into tractable pieces and addresses each of them. Then it explains how the CyberCarrier Solution maps onto that functional architecture. Finally, it explores how Lucent will evolve its CyberCarrier Solution through future management system innovations.

Backhaul facilities collectively represent a major expense item for a wireless service provider. Today, backhaul facilities based on time division multiplexing (TDM) are the most common way to connect base stations and mobile switching centers (MSCs) to transport bearer traffic, signaling, and maintenance data. Asynchronous transfer mode (ATM) technology makes it possible for wireless networks to integrate voice and data transmission, to offer fast, simplified multiservice provisioning, and to consolidate facilities efficiently. However, because of its logical and physical characteristics, ATM can make network management significantly more complex. Therefore, a service provider may want to consider outsourcing ATM service to a separate wide area network (WAN) business unit or to an outside carrier. This paper describes a non‐disruptive approach to managing ATM services for wireless equipment, using a wireless element management system (EMS) as the control point in a market domain. ATM services are represented in the EMS as virtual clouds within each market domain.

investment the service providers need [3]. Network providers require a stable and sustainable business model, bringing together network assets for reliable carrier-class connectivity services and key application assets from the Web world in a fair and equitable way.Furthermore, network connectivity providers evaluate their choices along multiple coordinates, looking for flexibility in their bandwidth provisioning plans. Bandwidth rearrangement capabilities may be required to address changes in traffic flow due to the popular upsurge of a new service, but also due to non-technical
