They query route servers for address resolution when destination stations are outside attached LANs. <\/p>\n<p>Edge devices also convert LAN frames into asynchronous transfer mode (ATM) cells and vice versa. They set up a switched virtual circuit in an ATM network, map the LAN frames into ATM frames and forward traffic to the ATM backbone. As such, they perform functions associated with routers and become major components in a LAN environment with an ATM backbone. <\/p>\n<p>On the other hand, edge devices also translate between different types of protocols. For instance, Ethernet uses an asynchronous transfer mode backbone to connect to other core networks. These networks send data in cells and use connection-oriented virtual circuits. IP networks are packet-oriented, so if ATM is used as a core, packets will be encapsulated in cells and the destination address converted to a virtual circuit identifier. <\/p>\n<p>Edge switches for WANs are multiservice units supporting a wide variety of communication technologies including Integrated Services Digital Networks (ISDNs), frame relays, T1 circuits and ATMs. Edge switches also provide enhanced services such as virtual private networking support, VoIP and quality of service (QoS).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Does Edge Switch Mean?
