4 LAN Technology Types Standard Ethernet Ethernet is the most common form of network communication used in today s local networks. Ethernet is known as the standard. Ethernet uses the CSMA/CD access method. CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

5 Ethernet Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

6 LAN Technology Types Ethernet 10 Base T How Fast = 10Mbps Baseband vs. Broadband = Baseband Type of Cable = Twisted Pair Cable Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

7 LAN Technology Types Fast Ethernet 100BaseTX 100BaseFX Both are 100Mbps Both are Baseband TX = Twisted Pair Cable FX = Fiber Optic Cable Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

8 LAN Technology Types Gigabit Ethernet 1000BaseT 1000BaseX Both are 1000Mbps or 1Gbps Both are Baseband T = Twisted Pair Cable X = Fiber Optic Cable Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

10 WAN Technologies Circuit Switching A physical connection path is established between the source and the destination typically through a series of circuits. Packet Switching Data is broken into packets which then each take a separate independent route to the destination where they are reassembled back into data. Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

11 WAN Technologies POTS, PSTN, T POTS Plain Old Telephone Service PSTN Public Switched Telephone Network T1/ E1 A T1 is a digital leased line consisting of 24 64K channels providing a transfer rate up to Mbps. An E1 is the European version with 30 channels providing up to Mbps. T3/E3 A T3 is basically 28 T1 lines (672 channels) providing a transfer rate up to Mbps. An E3 has 512 channels providing up to Mbps. Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

12 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, WAN Technologies - ISDN ISDN Integrated Services Digital Network BRI: Basic Rate Interface uses 2 64KB-channels to transmit data and 1 16KB-channel to transmit control information. PRI: Primary Rate Interface uses 23 64KBchannels for data and 1 64KB-channel for control information providing for essentially the same throughput as a T1 line.

13 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, WAN Technologies - SONET SONET/OC-x Synchronous Optical Network SONET is a network technology designed to carry large volumes of traffic over relatively long distances via fiber optic cabling. The data rates of a SONET network are divided into OC-levels (Optical Carrier Levels): OC-1 = Mbps OC-48 = Gbps OC-3 = Mbps OC-192 = 10 Gbps OC-12 = Mbps OC-256 = Gbps OC-24 = Gbps OC-768 = 40 Gbps

14 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, OC3 vs. STM1 The STM-1 (Synchronous Transport Module level-1) is the SDH ITU-T fiber optic network transmission standard. It has a bit rate of Mbit/s. Higher levels go up by a factor of 4 at a time: the other currently supported levels are STM-4, STM-16, STM-64 and STM-256. Beyond this we have wavelength-division multiplexing (WDM) commonly used in submarine cabling

15 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, SONET and SDH Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) are standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using lasers or highly coherent light from lightemitting diodes (LEDs)

16 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, WAN Technologies - Frame Relay Frame Relay A WAN where all nodes are connected through a packet switching cloud. You pay a base price for an agreed upon CIR (Committed Information Rate), and then pay additional for only the bandwidth actually used.

17 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, WAN Technologies - ATM ATM Asynchronous Transfer Mode Advanced packet switching network using fixed length packets (53 bytes). Provides data rates up to 622 Mbps.

18 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, WAN Technologies - MPLS MPLS Multiprotocol Label Switching MPLS is a technique, not a service. Known by many different names. Primary concept is the use of labeling. mpls-migration-explained.html

19 WAN Technologies - DSL DSL Digital Subscriber Line Provides high speed Internet connections using standard copper telephone wires. DSL comes in different flavors: ADSL Asymmetric Digital Subscriber Line allows POTS and data to be transmitted simultaneously. SDSL Symmetric Digital Subscriber Line cannot share data transmission with POTS. HDSL - High Speed Digital Subscriber Line HDSL was developed for T1 to transport DSL services at Mbit/s and Mbit/s over telephone local loops. VDSL Very High Speed Digital Subscriber Line allows access to the maximum bandwidth available on a standard phone line (13 55 Mbps). Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java,

20 Mohsen Aminifar ( MCITP, CCNA, CCNP, CISSP, CEH, VCP, LPIC, ISA, Exchange, Share Point, Java, WAN Technologies Cable Modem, SAT., Wireless Cable Modem Provides high speed Internet connections using a broadband cable connection. Satellite Provides high speed Internet connections using satellite communication. Typically used where DSL and Cable Internet are not available. Wireless Used primarily by mobile users. Provided through WiFi hotspots or through the cellular phone network.
