Canarie Satellite Caching Project
By: Sarah King, SNN Reporter
Over the years Newfoundland has been a leader in telecommunications history. The 1st Trans-Atlantic cables were run from Hearts Content, Newfoundland to Valencia, Ireland in 1866. These cables were run by the ship the Great Eastern, under the supervision of Cyrus Field. Some other important events in telecommunications history are:
According to todays statistics, in Newfoundland,
The short term outlook for schools is that Cable and ADSL will only be available in larger areas as T1 and Fractional T1 are too expensive for rural schools. Also, DirecPC will be the only high speed access for schools outside the "Trans-Canada Corridor".
In other words, most rural schools will need to purchase DirecPC technology if they wish to have a high speed Internet connection for the school.
DirecPC uses a satellite connection to download all information but any information that needs to be up-loaded must be sent out via a modem.
As with all things , DirecPC has its disadvantages.
ExpressVu can decommission your
system without telling you. (There have been 15 schools have
experienced this problem since the projects beginning in
Of course, there are also pros to DirecPC:
The CANARIE Project is a large scale caching project in schools in two school districts, Lewisporte/Gander in Newfoundland and Hastings/Prince Edward in Ontario. It has 25 remote terminals, 20 of which are situated in the two school districts. CANARIE uses satellites to send information to schools to be stored in a cache. The most popular sites from each school, each day are sent to Ottawa, which monitors the sites and then sends a list of the most popular sites to the satellite AnikE1. This satellite then sends the sites to a cache in each of the host schools where they are then stored. When a student tries to access these sites, they do not need to access the Internet at all, the computer simply finds the site in cache, and projects it onto the students screen.
The functions for CANARIE are divided into two sections, Proactive and Reactive.
Eventually CANARIE hopes to have a 50% hit rate which means, 50% of material requested by students will already be in the cache.
The bottom line is, CANARIE will speed up the Internet connections for everybody else by leaving less people accessing the Internet at any given moment.
