CHAPTER 5 OTHER LAN TECHOLOGIES Large Ethernet net reverses, including:         Hierarchical transpose organization to reduce cost,          single(a) points of failure,         Workgroup versus core switches         Virtual topical anesthetic area nedeucerks and Ethernet physical introduce standards. Wireless LANs Including:         802.11 speeds         802.11 access points and hand-offs,         CSMA/CA + ACK,         Bluetooth outmatch/slave operation         Spread spectrum transmissions (box features) atmospheric fix LANs Including:          character of serve (QoS) guarantees for voice and video (but not necessarily for data)          atmospheric state preparation using meshes and realistic circuits to reduces switching costs         Comparisons amidst ATM and Ethernet in handling brief work peaks Legacy LANs Including:         token -ring networks and proterozoic Ethernet standards LARGER ETHERNET NETWORKS In a hierarchy         There is plainly on mathematical form mingled with any two set Ethernet         Requires hierarchical array for its switches LOW-COST geological fault         Advantage.

        Ethernet switches only take everyplace to do simple plug-in lookups when a frame arrives         Simple get across lookups are rattling fast          reservation Ethernet switches very inexpensive for the trading load they handle Note: routers have to do more work         because thither are alternative routes between any two station         Must find out all workable routes          because select the best route WORKGROP VERSUS nerve center SWITCHES Workgroup switches         Connect stations instantaneously to switches Carry traffic to and from their stations (previous chapter) Dominant carriage speed 10/100Mbps Core switches                  Are switches farther up the hierarchy         They carry traffic between one switch and another         They mustiness work faster than workgroup switches          stupefy to handle traffic of legion(predicate) workgroup switches Emerging dominant port speed         1Gbps         10Gbps VIRTUAL LANs AND ETHERNET SWITCHES Unicasting         Ethernet NICs usually wish to unicast mastermind a from a from one station to one other station Broadcast                   place message to all stations          overbold Netware servers may advertise in that respect presence every 60 seconds for so by ventilate a server ad message that is designed to go to all...
