• Exercise Regularly

• Eat Smart

• Drink in Moderation

• Don’t pick up Hitch Hikers



Your Network

A network is a collection of computers and other hardware components interconnected by communication channels that allow sharing of resources and information, where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device then, the two devices are said to be in a network.



Your Network

Local Area network – The network portion that you or your Network Administrator controls. (Switches, Router, Firewall, physical connections, cabling in your building, etc.)

WAN – Wide area network, or maybe just to keep it simple, a telecommunications Circuit – Controlled by a Telco service provider and/or Network Provider.



Basic Rules – Network for Voice and Video


• Dedicated Bandwidth

• Quality of Service (QOS)

• Low Latency

• Managed Switched Network

• Cabling meets minimum standards

• Expert Support



Dedicated Bandwidth




Dedicated Bandwidth


Congestion can occur in shared circuits provided through standard commercial internet.

This creates many problems with voice and video; such as latency, jitter, and packet loss.



Quality of Service (QOS)


A method of giving some packets higher priority than others – Fast Lane. Priority is given to voice and video

QOS is useful on over-utilized intranet/WAN links, as well as LANs. QOS is not available across the public internet.



Low Latency


Latency - The time required for a packet to traverse a network from source to destination.

Jitter – A variation in latency over time.

Packet Loss - If a packet arrives too late, it is discarded without being used. You see an example of packet loss, which could be caused by excessive latency.



Managed Switched Network (vs. Hubs)


Hubs (repeaters) are old technology.

A hub sends (repeats) packets that are coming in on one port to all other ports.

Collisions can occur, so devices must listen for them, and so can only operate in half-duplex mode.

Bandwidth is shared among all devices and collisions force re-transmissions causing jitter



Cabling Standard


Voice and video are very sensitive to florescent lighting, high voltage. Ensure proper installation.

Test to ensure that the cable can meet or exceed transmission speeds and are error free.
