Are you puzzled about how to choose the best-fit managed service solution for your particular business needs? As a basic guide, the following are three typical high-level scenarios for deploying managed network services.
Scenario 1: Customer Owns Network and Shares Management Responsibility
Companies that already have an internal IP network can continue to manage it while out-tasking the management of onsite equipment -- usually known as customer-premises equipment (CPE), used for the managed service (see Figure 1).
The Roles and Responsibilities are as follows:
Managed service provider -- Sets up, maintains, and administers the equipment needed for the managed service, including company-owned equipment such as servers.
Company -- Managed service customer maintains and administers its internal network.
Scenario 2: Service Provider Owns the CPE; Customer Can Share Equipment Management with Service Provider
Some companies do not own a LAN, either because the location is new or the company already out-tasks its LAN services. In this situation, the service provider can manage the equipment needed for the corporate network as well as the managed service.
Many large enterprises like this arrangement because they can maintain physical control of the equipment while relying on the service provider for 24-hour network operational support (see Figure 2).
The Roles and Responsibilities are as follows:
Managed service provider -- Sets up, maintains, and administers the equipment for the managed services as well as the corporate network.
Company -- Monitors its corporate network through a Web interface provided by the service provider, receives regular reports on the network status and managed services, and is notified in case of a defined emergency.
Scenario 3: Service Provider Owns Equipment in its Own Facility; Customer Monitors Service Provider's Management of the Equipment
The difference between this scenario and the previous one is that most of the equipment is physically located in the service provider's "hosting" facility instead of on the customer premises.
The Roles and Responsibilities are as follows:
Managed service provider -- Sets up, maintains, and administers the corporate network and related managed services; most of the network equipment is physically located in the provider's computing center; the exceptions are the equipment for the LAN and network connections, as well as gateways for computers and IP telephony.
Company -- Monitors performance of its systems through a Web interface provided by the service provider, receives regular reports on the network status, and is notified in case of a defined emergency.
Summary: each of the three basic scenarios can be customized to meet your particular requirements. In upcoming posts, we'll identify some more specific application examples.
