Network Switching Aung Thu Rha Hein (g5536871) 2nd March 2014

What is network switching? ➔ A network device to connect segments within a network ➔ receive messages and send only to the targeted devices ➔ Type of Switch: ◆ Layer 1 Switch or Hub ◆ Layer 2 Switch ◆ Layer 3 Switch ◆ Layer 4-7 Switch (MultiLayer Switch)

Network Devices & OSI Layer Association OSI Layer Layer Name Devices 4-7 Transport, Session, Presentation,Application Multi-Layer Swtich 3 Network Routers, Layer 3 Switch 2 Data Link Switches, Bridges, NIC’s 1 Physical Hub or Layer 1 switch

Layer 1 Switch Hub ➔ port mirroring ◆ send network packages from one switch port to another port ➔ can’t filter messages. propagate to all connected devices ➔ not intelligence to find out best path for data packets.

Layer 2 switch ➔ perform bridging (Bridge with multiple ports ) ➔ Store & Forward Switch ◆ ◆ perform error-checking before sending network frames highly reliable & slow ➔ Cut Through Switch ◆ ◆ ◆ No error checking look up destination and forward it performance penalty

Layer 2 switch ➔ Fragment Free Cut Through Switch ◆ ◆ forward all frames initially if particular ports get many error frames, switch to store & forward mode ➔ Unmanaged/Intelligence Switch ◆ ◆ tracks & reports performance statistics have DB ASIC

Layer 3 switch ➔ layer 2 switch- filter & forward frames ➔ layer 3 switch- routing capability ◆ ◆ each ports is separate LAN port difference with router: physical implementation

Layer 4 Switch Session,Content switch ➔ responsible for the analysis and control of network traffic at transport layer ➔ vendor dependent ➔ can include firewall,IP security Gateway,Policy based routing & ACLs ➔ E.g. Cisco 3560 L4 Switch ◆ L2 switching, L3 routing & L4 content regarding forwarding, dropping, prioritizing, packets carrying

Layer 7 Switch Application,Content switch

Conclusion Complexity and Functionality (Ascending Order) Hub Bridge L2 Switch Router & L3 Switch L4 Switch L7 Switch Thanks & Questions
