2. 1 Introduction to Internet Protocol Over Satellite (IPoS)TIA-1008 Sebastian Coe TSM 601 Professor Bowman

3. 2 What is IPoS, and what does it do?

4. 3 Background History IPoS is the colloquial way of referring to Telecommunications Industry Association Standard (TIA) -1008[1] which is a proprietary standard developed and implemented by Hughes Network Systems. IPoS is the colloquial way of referring to Telecommunications Industry Association Standard (TIA) -1008[1] which is a proprietary standard developed and implemented by Hughes Network Systems. For any “Technical Contribution” to become a standard there must be extensive initial engineering committee work and subsequent TIA community review. [2] For any “Technical Contribution” to become a standard there must be extensive initial engineering committee work and subsequent TIA community review. [2] It was approved in November 2003[1] It was approved in November 2003[1]

5. 4 The Basics IPoS is a system that allows the use of satellites to extend the possibilities and range of the largest network of all, the Internet IPoS is a system that allows the use of satellites to extend the possibilities and range of the largest network of all, the Internet It uses space-based transponders as an additional link in wireless communications It uses space-based transponders as an additional link in wireless communications It has “always on” or “occasional” use reliability ratings over 99.8% which is even higher than that estimated for fiber optic communications [3] It has “always on” or “occasional” use reliability ratings over 99.8% which is even higher than that estimated for fiber optic communications [3]

6. 5 The Basics IPoS works as a kind of mirror in the sky to relay IP Datagrams sent from one part of the earth to another. IPoS works as a kind of mirror in the sky to relay IP Datagrams sent from one part of the earth to another. Think of IPoS as just one more link in the overall Internet Backbone. It is our cable in the sky that allows people in diverse locations to be connected. Think of IPoS as just one more link in the overall Internet Backbone. It is our cable in the sky that allows people in diverse locations to be connected.

7. 6 The Basics Remember, IPoS is just the mechanism that has been designed to get IP datagrams from one location to another when satellites are used to facilitate wireless communications. Remember, IPoS is just the mechanism that has been designed to get IP datagrams from one location to another when satellites are used to facilitate wireless communications. This means that IPoS and IP itself can be worked on and improved independently of each other. This means that IPoS and IP itself can be worked on and improved independently of each other.

8. 7 Why would anyone want IPoS? It eliminates geographical barriers that limit traditional methods of IP datagram transmission such as through ground based cable and wireless systems. It eliminates geographical barriers that limit traditional methods of IP datagram transmission such as through ground based cable and wireless systems. No need to invest in “expensive terrestrial networks.” Plus, it is very efficient and allows successful, simultaneous transmission with other services such as television.

9. 8 Services? IPoS allows “single-hop” transmission [6] of voice, data, and video that have been encapsulated in IP datagrams IPoS allows “single-hop” transmission [6] of voice, data, and video that have been encapsulated in IP datagrams IPoS systems also allow simultaneous transmission of digital television [6] using additional transponder capacity. Also radio, telephone, and non-IP communications services can be bundled with IPoS IPoS systems also allow simultaneous transmission of digital television [6] using additional transponder capacity. Also radio, telephone, and non-IP communications services can be bundled with IPoS

10. 9 Summary IPoS (TIA-1008) was developed by Hughes Network Systems IPoS (TIA-1008) was developed by Hughes Network Systems It is widely recognized within the telecommunications community as the medium for transmission of IP Datagrams It is widely recognized within the telecommunications community as the medium for transmission of IP Datagrams Think of IP and IPoS as two interconnecting highways. Where one starts another ends and vice-versa Think of IP and IPoS as two interconnecting highways. Where one starts another ends and vice-versa
