2-1 C HAPTER 2 N ETWORK P LANNING Introduction to Switching A network switch allows s imultaneous transmission of multiple packets via non-cros sbar switching . T his means that it can p artition a netw o rk more effici ently than br idg es o r routers .
N ETWORK P LANNING 2-2 Application Examples The Tig erSwitch 10/100 is not only designed to segment your netw ork, but also to provide a w ide rang e of o ptions in se tting up network connect ions . S ome typic al applicatio ns are descr ibed below .
A PPL I C ATION E XAM PLES 2-3 Network Aggregation Plan With 26 parallel bridgin g ports (i.e., 26 distin ct collision domains) , this switch can co llapse a complex n etw o rk down into a single efficient bridged node, incr easing ov er all bandw idth and through put.
N ETWORK P LANNING 2-4 Remote Connection with Fiber Cable Fiber op tic techn olog y allows for long er c abling than any o ther med ia type. A 100 Mbps multimode fiber (MMF) link can ru n up to 2 km, and a 100 Mbps sing le-mode fiber (SMF) link c an r un as far as 20 km.
A PPL I C ATION E XAM PLES 2-5 Making VLAN Connections VLANs ca n be base d on por t g roup s , or each data frame can be explic itly tag ge d to identify the VLAN gr oup to which it belongs. When using port-based VLANs , ports can eith er be assigned to one speci fic g roup or to all g roups .
N ETWORK P LANNING 2-6 Application Notes 1. Full-duplex operation on ly applies to point- to-point access (such as when a switc h is attached t o a workstatio n, ser ver or a n other s witc h ). When the switch i s con nected to a hub , both devi ces must operate in half-duplex mode.
