CHAPTER 5 OTHER LAN TECHOLOGIES Large Ethernet net take shapes, including:         Hierarchical flip-flop organization to reduce cost,          case-by-case points of failure,         Workgroup versus core switches         Virtual local anesthetic atomic number 18a networks and Ethernet physical stage standards. Wireless LANs Including:         802.11 speeds         802.11 access points and hand-offs,         CSMA/CA + ACK,         Bluetooth master/slave operation         Spread spectrum transmissions (box features) atmospheric kingdom LANs Including:          character of service (QoS) guarantees for voice and video (but not inescapably for data)          atmospheric state preparation using meshes and virtual circuits to reduces replacement costs         Comparisons amidst ATM and Ethernet in handling brie f work peaks Legacy LANs Including:         token -ring networks and proterozoic Ethernet standards LARGER ETHERNET NETWORKS In a hierarchy         There is only on mathematical racecourse between some(prenominal) two grade Ethernet         Requires hierarchical run for its switches LOW-COST SWITCHING         Advantage.

        Ethernet switches only take over to do simple plug-in lookups when a frame arrives         Simple table lookups are rattling fast         Making Ethernet switches very inexpensive for the traffic load they handle Note: ! routers have to do much work         because thither are alternative routes between any two station         Must identify all possible routes         Then select the best route WORKGROP VERSUS CORE SWITCHES Workgroup switches          associate stations directly to switches Carry traffic to and from their stations (previous chapter) preponderating demeanor speed 10/100Mbps Core switches                  Are switches farther up the hierarchy         They carry traffic between wizard switch and another         They must work faster than workgroup switches          form to handle traffic of many workgroup switches Emerging dominant port speed         1Gbps         10Gbps VIRTUAL LANs AND ETHERNET SWITCHES Unicasting         Ethernet NICs normally wish to unicast mastermind a from a from one station to one other s tation Broadcast                  Send message to all stations          new Netware servers may advertise there presence every 60 seconds for so by broadcast a server advert message that is designed to go to all...
