Moreover, Layer 2 switches deliver the ability to increase bandwidth to the wiring closet without adding unnecessary complexity to the network. At Layer 2, no modification is required to the frame content when going between Layer 1 interfaces, such as Fast Ethernet to 10 Gigabit Ethernet. In review, the network design properties of current-generation Layer 2 switches include the following: Layer 3 switches overcome the inadequacies of Layer 2 scalability by providing routing domains.
Responsibility[ edit ] The management of business continuity falls largely within the sphere of quality management and risk managementwith some cross-over into related fields such as governanceinformation security and compliance.

Business impact analysis BIA [ edit ] The entire concept of business continuity is based on the identification of all business functions within an organization, and then assigning a level of importance to each business function.
A business impact analysis is the primary tool for gathering this information and assigning criticality, recovery point objectives, and recovery time objectives, and is therefore part of the basic foundation of business continuity. The BIA can be used to identify extent and timescale of the impact on different levels of an organization.
For instance it can examine the effect of disruption on operational, functional and strategic activities of an organization. Not only the current activities but the effect of disruption on major business changes, introducing new product or services for example, can be determined by BIA.
Most standards require that a business impact analysis should be reviewed at defined intervals appropriate for each organization and whenever any of the following occur: Significant changes in the internal business process, location or technology Significant changes in the external business environment — such as market or regulatory change  Document management[ edit ] In large information technology environments, personnel turnover is inevitable and must be planned as part of business continuity.
