COMM 438 Lecture Notes - Lecture 15: Frame Relay, Optical Carrier Transmission Rates, Plain Old Telephone Service
Document Summary
Use switch, router or vlan switch with tcp/ip technology. Switch: connect lan switch, hubs or wireless access points together. Vlan switch is not restricted by physical locations. Devices in same location can connect to a different vlan. Devices in different locations can connect to the same vlan: eg. Technical capacity -- vlan is more difficult to set up. By the router with a dedicated cable. Router on the stick , every vlan shares one cable connected to the router. Connect lan and backbone networks together typically within the same organization. The circuit is leased from a carrier (shaw, telus, etc. ) Connect different networks that are distant within the same organization. Provides more secured connections and faster speed as wan is not affected by the internet traffic. Switched network (circuit switched network and packet switched network) Full duplex circuits from carriers leased lines or private lines. Bill flat rate per month with unlimited use of circuit (top plan,; expensive)
