You should use a bandwidth shaper, also known as a traffic shaper, to prioritize network traffic so that you can control data transmission rates by port usage. A bandwidth shaper can delay packets, letting you control bandwidth usage, a process known as bandwidth throttling, effectively limiting the transmission rate for the data packets. Many bandwidth shapers can categorize traffic by protocol or port and control transmission rates based on these categories. * Tutorial: You should use a bandwidth shaper, also known as a traffic shaper, to prioritize network traffic so that you can control data transmission rates by port usage. A bandwidth shaper can delay packets, letting you control bandwidth usage, a process known as bandwidth throttling, effectively limiting the transmission rate for the data packets. Many bandwidth shapers can categorize traffic by protocol or port and control transmission rates based on these categories. * A bandwidth shaper usually is employed as one of multiple quality of service (QoS) mechanisms. QoS often is implemented through a set of control mechanisms used to ensure minimum service levels for critical or high-bandwidth applications. * You should not use a multilayer switch. A multilayer switch is a network switch that operates at different layers within the Open Systems Interconnect (OSI) model. The simplest type of multilayer switch is a layer 3 (Network layer) switch that also provides high-speed routing. Some multilayer switches can perform various functions, operating up through layer 7 (Application layer) of the OSI model. * You should not use a content switch. A content switch is a specific type of multilayer switch that is used to balance the load among network servers of the same type, such as a Web farm with multiple Web servers. A content switch often also performs network address translation (NAT) for the servers, hiding the server address from the clients accessing the servers. * You should not use a load balancer. A load balancer performs the same basic function as a content switch, balancing the traffic load among multiple servers. * TAMPA, Fla., April 26 /PRNewswire/ -- PrepLogic, an industry leader in IT certification exam training, has released two new A+ certification exam training products designed specifically for the Amazon Kindle digital book reader.
