From: mpip@apies.frd.ac.za (Manoli Piperakis) To: netnews@apies.frd.ac.za Date: Thu, 7 Nov 1996 16:34:22 +0200 (EET) 50% Increase in International Bandwidth --------------------------------------- The agreement between Uninet and Internet Solutions (IS) to make use of the IS international circuit for incoming traffic after hours, has now come to full fruition. The extra bandwidth is available in the form of 2x 256kbps circuits, one from UCT and the other from the CSIR hub. The UCT circuit has been in operation for over two months with extremely positive results. As of 6 Nov.96, the circuit at CSIR is also operational. This means that on a daily basis, between 7pm and 7am, Uninet has 1.5Mbps to the US - an increase of 50% of the capacity usually available. For the keen enthusiasts interested in monitoring this extra bandwidth and its effects on response times, please bear in mind that Uninet cannot control the routing from the US to our sites especially when there are multiple routes available. There may be cases when the SAIX link is preferred by overseas routers causing that link to be used far more than the other two. We are aware of this and are attempting to optimise the load of traffic. Also, performing traceroutes to the US is not an indication of a preferred incoming route since a traceroute is considered outgoing traffic. One would have to perform a traceroute from an overseas site to Uninet to see which international route is preferred. Traffic graphs for the international circuits are available at the following URL's: 1. Full-time circuit through SAIX (1Mbps): http://www.frd.ac.za/uninet/mrtg/saix.html The green indicates traffic incoming from the US to Uninet. The blue indicates traffic outgoing from Uninet to the US and further. 2. Night-time (7pm-7am) circuit through UCT (Cape Town) (256kbps) : http://www.frd.ac.za/uninet/mrtg/tis-ct.html The blue indicates traffic incoming to Uninet from the US. 3. Night-time (7pm-7am) circuit through CSIR (Pretoria) (256kbps) : http://www.frd.ac.za/uninet/mrtg/tis-pta.html The blue indicates traffic incoming to Uninet from the US. Enjoy it !
