Internet Connections Presentation

  1. 1. What is it? Internet Connection
  2. 2. Imagine living without the internet today. Seems almost impossible right? However Less than 40 years ago this was the reality, there was no Internet. Nowadays we use the internet for just about everything. Facebook, Skype, Twitter, Whatsapp; just a few companies that have come from the internet boom, to name a few. Companies both nationally and internationally, big or small, all depend on the internet in order for their businesses to operate. Whether it is for email: ecommerce, cloud based solutions and so on, the internet has undoubtedly changed the way we do business. In this presentation I will speak about the different types of Internet Access available today, and consider the differences between them.
  3. 3. Just to make it clear broadband and Ethernet are types of internet. • Broadband is a lot cheaper and you have no control over the circuit. It could drop out at anytime and downloads speeds are always higher than upload speeds. Contention rates are usually 20/1 or higher. • With Ethernet the download and upload speeds are a lot faster and the will run simultaneously. Also if you ever had a problem the network would know and be able to look into the problem straight away. You have a lot more control but costs are a lot higher than broadband. Contention rate is1 to 1! This gives you complete control. When deciding what would be best for the customer you need to take into consideration – budget, bandwidth, reliability, location, type of data traffic. Ethernet vs. Broadband
  4. 4. Standard Speed Connections o Dial Up o ADSL o ADSL2 o Assured Broadband (voice calls only) High Speed Connections o Fibre Broadband o Coverged Broadband Premium Speed Connections o Fibre Ethernet What is Available?
  5. 5. Dial Up connections Dial up is the traditional method of accessing the internet through a modem that is connected to telephone lines. Dial up is outdated now. Because dial-up access uses normal telephone lines, the quality of the connection is not always good and data rates are limited. In the past, the maximum data rate with dial- up access was 56 Kbps
  6. 6. ADSL ADSL is the next generation after dial-up, with improved speed/performance and more importantly a split in the line allowing simultaneous broadband and telephone connections. It is supplied via traditional copper wiring. ADSL2 offers faster speeds. ADSL Benefits • Apart from the obvious speed advantages that ADSL connections offer, ADSL technology eliminates the need for a second phone line by allowing voice and data transfer at the same time (you can use the phone as normal while connected to the Internet). • Because ADSL transfers data digitally it eliminates the usual performance overhead associated with standard dial-up connections. In other words ADSL doesn't need to convert the data from digital to analogue and back again. • ADSL connections are Always on which makes the usual long wait to connect associated with dial-up a thing of the past Disadvantages * A DSL connection works better the closer you are to the telephone exchange in your location. * The connection is faster to download (receive data) than to send information. * This service is not available in all locations
  7. 7. Assured Broadband What is it? - Assured IP is a voice only Broadband connection. - These Broadband connections are 1:1 contended (uncontended) and prioritise IP voice traffic above all other traffic. - They are solely for the purpose of connecting IP Telephony systems to our network. Suitability: - It’s ideal for small to medium sized businesses and offers optional capacities of between 5 and 30 concurrent calls. Further benefits include prioritised voice traffic across the network, UK-based 24/7 support and exacting service level agreements (SLAs).
  8. 8. • Converged Broadband provides high quality internet and IP telephony access on a single line, from one supplier • With Converged Broadband you need buy only one service for voice and data Converged Broadband Suitability: • Converged Broadband is ideal for small businesses who are looking for a cost effective way of having two services for the price of one. The service supports up to 10 calls at a time Benefits of Converged Broadband • A single connection for voice and data • Guaranteed voice quality • 24/7 UK-based support • Advanced diagnostics tools
  9. 9. Fibre Connections
  10. 10. • Difficult and Expensive to Install Fibre is costly and disruptive to install, companies often have to dig up long trenches to put the cable in. • Equipment and Power Required The end user has to have some new equipment installed: the NID and a power source for it. The power source has to continually take electricity from the user's building or home Fibre Connections Disadvantages Advantages • Speed and Reliability The main advantage of fibre is the speed and reliability in transmitting signals. This means that users can both upload and download things quickly, and also have high quality streaming media. • Long-Term Use FTTP is expected to be usable as-is for a very long time. • Durability Fibre optic cable is generally more durable than copper. This means that the network doesn't need to be serviced as often, which is more convenient for the ISP and the users. • Remote Monitoring and Control The nature of the cables also makes fibre optic networks easier to monitor than others. Problems with the network can be identified remotely at the ISP, with some devices able to detect where a problem within about 5 feet (1.5 meters). This makes it easier for technicians to repair any faults quickly. Business Benefits Fibre optic broadband is very easy to integrate with other features and systems. These include: •VoIP services •Online Data Backup •Shared work and collaboration tools •Cloud-based computing •Video conferencing
