**** The Hebrew University of Jerusalem **** **** Computation Center **** News Bulletin #101 1-May-1997 Today's topics: - Internet business-class connectivity. --------------------------------------------------------------- Improved Internet IUCC Service The Current Situation Israel Universities are connected to the Internet via 2 communications lines: one line is connected to IBM with capacity of 1Mb/s and is mainly used for connecting to the USA; the second line, with capacity of 256Kb/s, is connected to CERN in Geneva and is used for connecting to Europe. These lines do not meet the current communication demand, but there are difficulties in getting the required budget to enlarge the network capacity. The main problem in the current system of operating the network is that all network users have equal access priority. A mechanism has been developed at Tel-Aviv University for MACHBA which can change this situation. The Improved Service System In May 97, the international line via IBM will be upgraded to its full capacity of 1.5Mb/s. * 1.25MB/s will be used for normal communications to USA and Europe * 0.25Mb/s will be set aside by IUCC for the improved service system. The system will enable different network priorities according to source and destination of communication and according to the communication protocol. The system is able to measure the exact communication capacity which received priority queuing. By using this system, whoever wishes to get high priority communication, can do so, for a fee. An interested party defines in advance the type of communication which should be given priority according to the above mentioned factors, (it is not possibleto give priority to a particular user of a computer, only to all users of a particular computer) for which payment will be made each quarter. IUCC's Improved Service Prices The price for the service, based on real cost, is $180 per gigabyte. The minimum charge is $100 a month. By subscribing to the improved service, a user will be allowed access to a special WWW proxy, which interogates the other MACHBA proxies for requested URLs before issuing a request abroad. By doing so, response time is improved, and bandwidth is saved. People using the service have reported a 3-10 fold performance improvement. A party which is worried that this arrangement may cause budget overruns can choose an alternate pricing scheme, in which communications priority will be given at a set data rate. Communications which exceed this set rate will be given normal priority, according to the amount of excess at each given moment. In this way, the amount of priority communications can be limited in advance, thus limiting the price. The price for this arrangement is $625 a month for a data rate of 16Kb/s. Applications for the Improved Service If you are interested in getting the Improved Internet Service, contact your local computer center (02 - 6584280) for further details.
