53. width A switch is a network device which creates point to point and loop topologies between individual data network elements on an as needed basis The Fibre Channel Switch overcomes this constraint allowing point to point and loop topologies to be connected into a Fabric The Fabric is loosely woven connections which can be configured for specific applications The Fibre Channel ANSI specification identifies classes of service which can be used to tailor the connection e Class 1 is a dedicated connection service e Class 2 is a guaranteed delivery service e Class 3 is a datagram service no guaranteed delivery e Class 4 is a guaranteed bandwidth service e Class 6 is a dedicated unidirectional service The Fibre Channel switch has two methods of operation frame and circuit switching The frame switching method is used for class 2 3 and 4 while circuit switching is used for class 1 and 6 The circuit switch is a physical connection between ports while the frame switch creates a virtual connection utilizing buffering between ports The switch will support all topologies and can configure each port for point to point Fabric port or F_Port or loop operation Fabric Loop port or FL_Port This allows low cost loop only devices to become part of the Fabric Public Loop The Fibre Channel Switch is used for applications that require increased bandwidth connections and delivery service beyond loop or point to point configurations The swit
