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

  2. How does IP over Satellite Work? Sebastian Coe - IPoS (TIA-1008)

  3. Overview • IPoS is governed by TIA standard 1008 • It divides the use of IPoS into three main ‘segments’ [1] (Hughes Network Systems) Sebastian Coe - IPoS (TIA-1008)

  4. User Segment • Individual PC users have a small outdoor satellite dish that has a direct ‘line of sight’ orientation towards a satellite in the sky. [6] • Inside, the user has a special modem that connects the outdoor portion and indoor portion of the user segment [6] Sebastian Coe - IPoS (TIA-1008)

  5. User Segment • At the user segment the demodulated IPoS packets can be ‘rerouted using standard Ethernet card or wireless communication techniques such as WLAN.’ [6] • Put simply, once IPoS packets are on the ground, they can be easily retransmitted through well known systems Sebastian Coe - IPoS (TIA-1008)

  6. Hub Segment • The Hub Segment serves as a ‘gateway’ for large numbers of IPoS users. [1] • It is a ground link between users, satellites, and the rest of the networks that make up the internet Sebastian Coe - IPoS (TIA-1008)

  7. Hub Segment • The Hub segment is in charge of converting packets from ‘one protocol to another’. [1] • It is in charge of making sure that traffic is properly routed through the network. [1] Sebastian Coe - IPoS (TIA-1008)

  8. Space Segment • Ku Band Transponders [6] • Bi-directional transmission is possible between user and hub segments [1] • Bent pipe transmission is used [1] • One hub segment can access multiple space segments simultaneously [1] Sebastian Coe - IPoS (TIA-1008)

  9. IPoS Protocol • IPoS protocol is An extension of IP It is designed to allow IP packets to travel Through a space Based medium (Hughes Network Systems) Sebastian Coe - IPoS (TIA-1008)

  10. Quick Review • IPoS works through the coordination of the user, hub, and space segments. • IPoS uses space based transponders, it uses microwaves to transmit information Sebastian Coe - IPoS (TIA-1008)

  11. Quick Review • IPoS encapsulates IP packets so they can travel across the satellite network. IP and IPoS work together, but can be developed separately. • The hub segment has the major task of bringing together and getting user information to and from the Internet Sebastian Coe - IPoS (TIA-1008)

  12. Notes • IPoS allows for up to 155Mbps bandwidth • Required Equipment: IPoS enabled modem, user equipped satellite dishes, dedicated satellite transponders, ground base stations Sebastian Coe - IPoS (TIA-1008)
