What this means is that a certain number of users need to share the same bandwidth.<\/p>\n<p>&#8220;We are planning on overselling our uncapped product at 15:1 to 20:1, which we believe is a lot better than the current products in the market,&#8221; said Fialkov.<\/p>\n<p><strong>The need for fair use policies<\/strong><\/p>\n<p>The Cybersmart CEO explained that there are a small number of users &#8211; around 8% according to their trials &#8211; who believe the service should provide them with full speed at all times.<\/p>\n<p>&#8220;This means that these users try to download at full speed 24\/7, leaving inadequate bandwidth to serve the other users who share the bandwidth,&#8221; said Fialkov.<\/p>\n<p>The challenge, explained Fialkov, is:<\/p>\n<ul>\n<li>For all customers to have a good experience without noticing that their bandwidth is contended;<\/li>\n<li>To manage the 8% of users who intend to download continually without enforcing a harsh throttling policy.<\/li>\n<\/ul>\n<p>&#8220;The ISPs that do not arbitrarily throttle subscribers employ some form of shaping,&#8221; said Fialkov. &#8220;The most common shaping equipment used is the <a title=\"Cisco\" href=\"http:\/\/businesstech.co.za\/forum\/showthread.php\/2037-Cisco\">Cisco<\/a> SCE engines (a.k.a. Allot) which provide a wide range of options.&#8221;<\/p>\n<p>Fialkov pointed out that\u00a0automatic shaping software can help to ensure a good experience on uncapped accounts.<\/p>\n<p>Shaping peer-to-peer (P2P) traffic, typically associated with online piracy, will further help to spread bandwidth fairly. &#8220;P2P services can use up to 50% of the available bandwidth, but is only used by 10% customers,&#8221; said Fialkov.<\/p>\n<p>&#8220;The biggest problem with P2P downloads is that it opens hundreds of TCP connections that can be sustained for many hours. As a comparison, loading a webpage opens about 10 connections that last for around 10 seconds each,&#8221; explains Fialkov.<\/p>\n<p>Fialkov highlighted that many P2P programs come with automatic encryption of traffic, making shaping challenging. &#8220;If you cannot classify it, you cannot shape it,&#8221; said Fialkov.<\/p>\n<p><strong>The Cybersmart solution<\/strong><\/p>\n<p>Cybersmart wants an uncapped ADSL product which has the following characteristics:<\/p>\n<ul>\n<li>Unshaped bandwidth;<\/li>\n<li>Can be used for business purposes where unknown or unclassified traffic is not slowed down;<\/li>\n<li>No throttling policy;<\/li>\n<li>Where subscribers do not know that their bandwidth is contended;<\/li>\n<li>Where the 8% of heavy users could be managed without upsetting them too much.<\/li>\n<\/ul>\n<p>The solution which provides Cybersmart with what it needs, is a product called Netequalizer. &#8220;We were so impressed that we asked for distribution rights for South Africa, which was granted to us,&#8221; said Fialkov.<\/p>\n<p>&#8220;The way this product works, is it keeps track of the top TCP connections on a network. The equalizer rates the connections based on how long the connection has been alive and how fast it is going. It will then slow the &#8216;top&#8217; connections down so they are not unfairly using the bandwidth,&#8221; explains Fialkov.<\/p>\n<p>This solution means that business applications which use encryption are not arbitrarily slowed down (as is the case with many shaping solutions).<\/p>\n<p>Fialkov added that the TCP rules will only be enforced during times when the network load is high. &#8220;If we are not under peak load then no connections are equalized at all,&#8221; said Fialkov.<\/p>\n<p>Cybersmart is further planning to play completely open cards with its subscribers. &#8220;Our customers will be able to see if one of their connections has been equalized by using our ADSL usage page,&#8221; said Fialkov.<\/p>\n<p>One limitation of the Netequalizer system is that it cannot rate limit a user (hence limit the speed per account) &#8211; Cybersmart will overcome this issue by bundling ADSL accounts and ADSL lines.<\/p>\n<p>Fialkov concluded by saying that Cybersmart is planning to launch its home uncapped product before 1 June, with its business uncapped ADSL service following towards the end of the year.<\/p>\n<p><strong>Related articles<\/strong><\/p>\n<p><a title=\"Telkom upgrading broadband speed and infrastructure\" href=\"http:\/\/businesstech.co.za\/news\/telecommunications\/8585\/telkom-upgrades-broadband-speed-and-infrastructure\/\" target=\"_blank\"><strong>Telkom upgrading broadband speed and infrastructure<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cybersmart is set to launch its first uncapped ADSL products by June, and the company&#8217;s MD, Laurie Fialkov explains its innovative approach to provide uncapped broadband in SA<\/p>\n","protected":false},"author":2,"featured_media":9912,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[21],"tags":[79,435,26,437],"class_list":["post-9858","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-telecommunications","tag-adsl","tag-cybersmart","tag-headline","tag-laurie-fialkov"],"_links":{"self":[{"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/posts\/9858","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/comments?post=9858"}],"version-history":[{"count":9,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/posts\/9858\/revisions"}],"predecessor-version":[{"id":9916,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/posts\/9858\/revisions\/9916"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/media\/9912"}],"wp:attachment":[{"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/media?parent=9858"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/categories?post=9858"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/businesstech.co.za\/news\/wp-json\/wp\/v2\/tags?post=9858"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
