This increases the user equipment cost significantly since the transmission tube is the most expensive part of a VSAT terminal (and a receive-only terminal doesn't need one). In the simplest form, you could do PPP over a fixed bandwidth RF link. Most services do (& will) use something more sophisticated since (a) the duty cycle for a single terminal is usually low and (b) satellite bandwidth is expensive. The operators want to share the bandwidth across as many users as possible (while still providing acceptable service). > I am > familiar with the DirecPC approach of using a terrestrial > (dial, ISDN) > uplink from the home. Is the bandwidth symmetrical or asymmetrical? Since most of these systems are designed for web access, the bandwidth will almost always be asymmetrical. But in some designs, particularly the Ka-band systems in development, that's a matter of provisioning rather than the architecture. Meaning that if you had a user that needed symmetric access (or, rather, was willing to pay for it), you could set up channels with the same rates in both directions. Nevertheless, the majority of these systems are designed expecting that most users will want to consume more data than they generate. > > - How much bandwidth is possible? I see that DirecPC > advertises 400Kb. What > are the issues that affect how much bandwidth one can use? > Sharing satellite bandwidth is a zero-sum game. If your transponder can handle 45Mbps (a typical value), you can share that across all the users you want but it has to add up to 45Mbps. If you've ever studied communications channels, you know you can trade channel utilization (percentage of time that the channel is not idle) for data delay. In other words, you make users wait in queues so they can transmit at the most convenient time. However, if you make them wait too long, they get annoyed. There can be significant overhead in these channel sharing (DAMA, Bandwidth on Demand) schemes since you have to tell users when to transmit. > Any conferences/tutorials/whitepapers/books that people can > recommend to > learn about this stuff? Lots of conferences: -) University of Maryland has an annual Internet over satellite conference (I couldn't find a URL) -) The annual Ka-utilization conference talks about new Ka-band (duplex) systems -) MOBICOM -) 'Internet Via Satellite,' marketing oriented but useful if you want to find out what people are doing, http://www.actconferences.com/Satv4/index.htm -) IEEE Communication Society usually has some sessions at ICC, http://www.icc00.org/technic/pglance.htm ...Hopefully, folks on the mail list can contribute additional ones.

(Reference - ISO/IEC 13818-1) Regarding other Qs: The DVB standard defines 5 different data broadcasting profiles (as listed below) over DVB compliant broadcast networks. Each profile is defined for a different application area. Data Piping (data is carried directly in the payloads of MPEG-2) Data Streaming (data is carried in PES packets defend in MPEG-2) Multiprotocol Encapsulation (data is encapsulated in DSM-CC sections, which are compliant with the MPEG-2 private section format) Data Carousels (data is transmitted in a DSM-CC data carousel as defend in MPEG-2) Object Carousels (data is transmitted according to the DSM-CC object and data carousel specifications as defend in MPEG-2). The data broadcast specification profile for multiprotocol encapsulation (third in the list) supports data broadcast service that requires the transmission of communication protocol datagrams over DVB networks. If the LLC_SNAP_flag is set the payload carries LLC/SNAP encapsulated datagrams, following the MAC_address_1 field. When it carries an IP datagram directly, the LLC_SNAP_flag is set zero. The fragmentation and reassembling service is provided using the section length, section number and last section number. For example, the section number indicates the fragment number, if the datagram has been fragmented. The Medium Access Control (MAC) address (e.g., Ethernet address) of the destination device will be encapsulated using the MAC address fields. The multi-protocol encapsulation profile is becoming an open standard within industry, although other data broadcasting profiles have also implemented by some manufactures In a simple configuration of a satellite-based DVB network, a low cost receive only satellite terminal may be used to construct a cost-effective high speed simplex distribution. The server transfers the data to the client through the higher speed satellite link. A client networking device (the client computer itself or the router) has two network interfaces; one connected to the receive DVB link and the other connected by an Internet Service Provider to the terrestrial network. The hub router forwards data through the satellite network while the return data may be sent through the terrestrial - ISDN, ADSL, dialup links (or in future using a low power satellite return link - see new Astra work).

Unless something's changed, they don't offer Internet access, just private networking. If that's your need, then it'll work. If you really didn't want to install hundreds of locations, it may not be what you want. If I could get bidirectional VSAT at DSL prices (with reasonable equipment charges) and including Internet connectivity, I'd certainly have a number of applications for that. The Gilat/DISH offering is in that direction. Nothing else I've seen yet is available for less than 100 times the price (monthly) and excessive equipment pricing (i.e. no, I don't want a 12 foot dish and dedicated C-band transponders). > ----- Original Message ----- > From: "Chris Metz" > To: > Sent: Monday, June 05, 2000 7:27 PM > Subject: IP over Satellite Questions/References > > > Hi- > > Based on a reference to Dish Network and Gilat I heard the other day on > > CNBC I am suddenly very curious about the use of satellite for broadband > > access to the home or business and IP over Satellite in general.

If I'm wrong about the event Aaron was referencing, my apologies to all. I was told the event was incorrectly listed in an industry pub. as the University's 2nd annual event, so the confusion is understandable. Actually, Aaron may be amazingly prescient -- the director of the University's center for Satellite & Hybrid Networks has approached us about producing the event next year with the University.

This increases the user equipment cost significantly since the transmission tube is the most expensive part of a VSAT terminal (and a receive-only terminal doesn't need one). In the simplest form, you could do PPP over a fixed bandwidth RF link. Most services do (& will) use something more sophisticated since (a) the duty cycle for a single terminal is usually low and (b) satellite bandwidth is expensive. The operators want to share the bandwidth across as many users as possible (while still providing acceptable service). > I am > familiar with the DirecPC approach of using a terrestrial > (dial, ISDN) > uplink from the home. Is the bandwidth symmetrical or asymmetrical? Since most of these systems are designed for web access, the bandwidth will almost always be asymmetrical. But in some designs, particularly the Ka-band systems in development, that's a matter of provisioning rather than the architecture. Meaning that if you had a user that needed symmetric access (or, rather, was willing to pay for it), you could set up channels with the same rates in both directions. Nevertheless, the majority of these systems are designed expecting that most users will want to consume more data than they generate. > > - How much bandwidth is possible?

If your transponder can handle 45Mbps (a typical value), you can share that across all the users you want but it has to add up to 45Mbps. If you've ever studied communications channels, you know you can trade channel utilization (percentage of time that the channel is not idle) for data delay. In other words, you make users wait in queues so they can transmit at the most convenient time. However, if you make them wait too long, they get annoyed.

We use this opportunity to remind the potential contributors that the deadline for special session "The New Millennium Telecommunications in the Alps-Adria Countries" is approaching. From the papers presented at SoftCOM 2000, a set of the most representative papers (or their integrals) will be selected for publication in the August 2001 issue of the IEEE Communications Magazine. Deadline for the Feature Topic: Complete manuscript to be received by July 15, 2000 Notification of acceptance: July 31, 2000 The Feature Topic includes, but it is not limited to: -historical background, developments, -operation statistics and experiencies, user (universities, institutes, schools) opinions, -the newest technologies and services, -development of telelearning and videoconferencing, -Web applications and information systems, -security aspects, -plans for future,toward the new millennium, -the role of universities and institutes, -the role of the national and regional operators and companies, industry and institutions, -joint projects, joint institutes and laboratories between academic and operators and companies, industry and institutions, -participation of academic institutions in education of professionals from industry and vice versa, Participation in this FT is expected from institutions which cover academic networking (such as CARNet in Croatia, Arnes in Slovenia), as well as from universities, institutes and schools as users, particularly in the Alps-Adria region.

The conference will bring together researchers and practitioners of every aspect of digital communications and networks, presenting the most up-to-date results and achievements in these fields. The IEEE INFOCOM 2001 program committee is soliciting original papers describing state-of-the-art research and development in all areas of computer networking and data communications. Topics of interest include, but are not limited to, the following: BISDN and ATM Network management and control Billing and pricing Network measurements and testbeds Communication protocols Protocol design and analysis Congestion and admission control Quality of service Flow control Queueing theory Cryptography, information hiding Scheduling Internet and web applications Security and privacy Optical networks Storage area networks Mobile networks Switching and switch architectures Multicast Traffic management and control Multimedia Routing Multiple access Web performance and caching Network architectures Wireless networks PAPER SUBMISSION ================ Papers must be submitted electronically according to the instructions described in and summarized below. Proposals for panels, half- or full-day tutorials should be submitted to the respective chairs. Please refer to the conference web site for further details. Papers must be formatted according to the IEEE standard format except for the font size, which MUST be 11pt. To make it easy to adhere to the formatting standard, we offer templates and samples for LaTex, MSWord, and FrameMaker (please refer to the pertinent web pages at ). ------------------------------------------------------------------- PAPERS THAT DO NOT COMPLY TO THE ABOVE FORMAT CANNOT BE REVIEWED ------------------------------------------------------------------- Submissions must be in PDF or Postscript. Postscript papers must use only standard PostScript fonts: Times Roman, Courier, Symbol, and Helvetica. (Please note that Postscript output from MSWord typically does not work on non-Microsoft platforms. The use of the Apple LaserWriter II printer driver is strongly recommended). The above formatted papers can be submitted in a compressed form (gzip, zip, WinZip, compress). Because of the size limitation on the final manuscript, and to ensure that the reviewed paper and the final version have a similar size, ----------------------------------------------------- PAPERS WITH MORE THAN 11 PAGES CANNOT BE REVIEWED ----------------------------------------------------- (this is roughly equivalent to 20 double-spaced pages). Papers must be submitted electronically using the Web site at . This web page contains exact and detailed instructions about the submission process. Author's contact information must be provided during submission. To save space, authors may omit this information from the paper itself. Authors will receive an immediate notification of the successful receipt of the file containing their paper. Subsequently, a formal notification will be sent after verifying that the paper can be printed successfully. ------------------------------------------------------------------------- | SUBMISSIONS WILL ONLY BE ACCEPTED BETWEEN MAY 1ST AND JULY 5TH, 000. | -------------------------------------------------------------------------> SUBMISSION DEADLINES ARE STRICT! PAPERS THAT HAVE BEEN IMPROPERLY SUBMITTED OR IMPROPERLY FORMATTED BY THE SUBMISSION DEADLINE WILL NOT BE CONSIDERED. TO AVOID LAST MINUTE PROBLEMS, AUTHORS ARE ENCOURAGED TO SUBMIT THEIR PAPERS WELL IN ADVANCE OF THE DEADLINE. THE REVIEW PROCESS ================== Each paper will typically be reviewed by three independent reviewers, whose reviews will be relayed to the corresponding author. Following last year successful experiment, authors will have a chance to provide a limited rebuttal on the reviews before the program committee makes its final decision. TRAVEL GRANTS ============= Limited travel assistance to students, post-docs and junior faculty presenting a paper in the conference will be available.

These can now be found at. www.metrodata.co.uk/satellite in html format so they are quicker to download. There's loads of different apps there and I'd if anyones got time take a look around. I'll be adding to it all the time. I've found recently Service Providers selling Internet Over Satellite services before they now how to deliver it. Or whether it can be delivered at all. It seems like there are some strange speeds being delivered: 60/12Mbps and 70/12Mbps would be examples. These are really hard to transport across leased line infrastructure. Satellite Modems are generally BNC or HSSI interfaced at the higher rates. This is fine when you are looking at Asymmetric services below DS-3 (BNC) or 52Mbps (HSSI), but when you want to offer 60/12Mbps it presents a bit of a problem. The reason for this is that the signalling and line structure of terrestrial links is clearly set out for E1, E2, E3, DS3, E4 and STM-1. The interface on our terrestrial equipment conforms to these speeds, however the BNC interface on the Satellite Modem operates at flexible speeds usually. What I am doing is developing a module portfolio that can transport any Satellite Ratio up to 155/155Mbps. To do this I need to know the line driving capabilities of Satellite Modem G.703 interfaces and whether they operate at fixed rates. Once I know these rates I can deisgn correct timing on our modules to match the satellite speeds. If there are any Satellite Modem manufacturers who can tell me what speeds their BNC interfaces work at I would be very happy. Below are some logical satellite speeds that we can transport. Non standard speeds tend to be 12/60/72Mbps. 64Kbps 128Kbps 256Kbps 384Kbps 512Kbps 768Kbps 1.024Mbps 1.544Mbps (T1) 2.048Mbps (E1) 3.088Mbps (2T1) 4.096Mbps (2E1) 4.632Mbps (3T1) 6.144Mbps (3E1) 6.312Mbps (T2) 8.448Mbps (E2) 10.271Mbps (Common Data Link - CDL) 34.368Mbps (E3) 44.736Mbps (T3) 139.264 Mbps (E4) 155.52 Mbps (STM-1/OC-3) Thanks a lot. If anyone knows of any good links regarding Internet Over Satellite please email them so I can add them to my page. Or if you've got White Papers that I can upload just send them over.
