CHAPTER 5 OTHER LAN TECHOLOGIES Large Ethernet net figure outs, including:         Hierarchical counterchange organization to reduce cost,          case-by-case points of failure,         Workgroup versus core switches         Virtual local anesthetic bea 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 secernate 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 fracture costs         Comparisons amidst ATM and Ethernet in handling brief work pea ks Legacy LANs Including:         token -ring networks and proterozoic Ethernet standards LARGER ETHERNET NETWORKS In a hierarchy         There is only on mathematical raceway between whatsoever two lieu Ethernet         Requires hierarchical get down 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 job loa d they handle Note: routers have to do ! more(prenominal) work         because thither are alternative routes between any two station         Must identify all viable routes         Then select the best route WORKGROP VERSUS CORE SWITCHES Workgroup switches          plug in stations directly to switches Carry traffic to and from their stations (previous chapter) paramount port speed 10/100Mbps Core switches                  Are switches further up the hierarchy         They carry traffic between 1 switch and another         They must work faster than workgroup switches          boast 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 station Broadcast                   Send message to all stations          young Netware servers may advertise there presence every 60 seconds for so by broadcast a server advertisement message that is designed to go to all...
