Definition of a Network A Network is used to connect two or morecomputers in order to share resources. A good example would be a pc to a server or a pcto a network printer. Types of networks include home, enterprise,internet, intranet, and extranet.#AvayaATF 2014 Avaya Inc. All rights reserved. 7 8. OSI ModelApplication LayerPresentation LayerSession LayerTransport LayerNetwork LayerData Link Layer#AvayaATF 2014 Avaya Inc. All rights reserved.Physical Layer8 9. What is Network Bridging Network Bridging allows two or more communicationnetworks or network segments to create and aggregateNetwork. Bridging is different than routing which allowsnetworks to communicate independently as separatenetworks. A Bridge is a network device that connects multiple networksegments. Reference our OSI Model where bridging acts inL1 and L2. There are many types of topologies and technology thatbridging works in such as Ethernet, token ring, fddi, bus,star, and bus.#AvayaATF 2014 Avaya Inc. All rights reserved. 9 10.

What is Spanning Tree Protocol Spanning Tree Protocol (STP) is a Layer 2 protocol that runson bridges and switches. The specification for STP is IEEE802.1D. The primary purpose of STP is to ensure that youdo not create loops when you have redundant paths in yournetwork. Loops are deadly to a network! Invented by Dr. Radia Perlman when she was a softwaredesigner at DEC. Dr. Perlman also was a major contributorin the development of OSPF, IS-IS, and TRILL. http://web.mit.edu/invent/iow/perlman.html#AvayaATF 2014 Avaya Inc. All rights reserved. 11 12.

All rights reserved. 14 15. Ethernet Switching Definition Ethernet Switches evolved from the earlier HUB. ASwitch is a Network Device that connects manyother Ethernet Devices together. Switching is moreadvanced than a hub because it only sends amessage to the device that needs the message andnot broadcast to the entire segment or local areanetwork. Most Switches today allow for Multilayer Switchingallowing networks to connect between each other atLayer III. VLAN Switching Going from one vlan to another.#AvayaATF 2014 Avaya Inc.

As stated earlier, routers connect more than one network atLayer III. Routers use routing protocols such as RIP, OSPF, IS-IS,BGP, and EIGRP to automatically develop routing tables thatcontain the network address (TCP/IP) of a particular addressautomatically. Routers are also used many times to set policies that canchange the behavior in which traffic flows by sending in aparticular direction or blocking specific networks like afirewall would.#AvayaATF 2014 Avaya Inc.

OSPF Specifics OSPF Uses Areas as specific Routing Domains. All Areas must be connected to Area 0 via an ABR(Area Border Router) OSPF is a Link State Protocol and sends link stateadvertisements to provide the specific informationaround networks and routes. OSPF is and Industry Standard and is NotProprietary like EIGRP. Widely used in theEnterprise Space.#AvayaATF 2014 Avaya Inc. All rights reserved. 22 22. RIP Routing Information ProtocolResp Resp#AvayaATF 2014 Avaya Inc. All rights reserved.Req ReqReq RespNote: RIPv2 supportsCIDR /RFC 245323 23. RIP Timers Update Timer Controls interval for between response.Default is 30 seconds. Invalid Timer Defines how long a routing update can be inrouting without an update. Also called an expiration timer.After 180 seconds the route goes unreachable. Flush Timer You guessed it, how long a route is invalid orunreachable before the route is flushed from the routingtable Hold-Down Timer this timer is started when the hop countis changing from a lower to a higher value. NOTE = Hopcount determines the best route to the destination. Max HopCount is 16.#AvayaATF 2014 Avaya Inc. All rights reserved. 24 24. Border Gateway Protocol (BGP)#AvayaATF 2014 Avaya Inc.

A best-effort based network or service is not able to provide the required Quality ofService for critical business applications especially those requiring real-timeaction/decision. Many things can happen to a packet as it travels through the network:#AvayaATF 2011 Avaya Page 41 of 190 Inc. All Rights Reserved Errors Packets might be corrupted due to noise and interference. Loss Packets might be dropped if routers are too busy, or for lack of available bandwidth. Latency It might take a long time for each packet to reach its destination. Jitter Packets might take different routes resulting in a variation of delays. Out-of-order delivery Packets might arrive out of order. Not only Voice and/or Video, but many new applications require QoS.Topic 1: Quality of Service in the Network 41. #AvayaATFCompetitionsReactive Networks Expensive withadditional overlay Reactive usinghistorical mining Incomplete withno end-to-endvisibility Proactivemonitoring Agentseverywhere GraphicalreportingNetwork-wide Proactive QoS MonitoringAvaya-on-Avaya Access SolutionPoor sessionqualityCall to IT andtroubleshootingbeginsSynthetic testssentTrouble segmentsidentified BEFOREcall begins 2014 Avaya Inc.
