Enterprise Bandwidth Vs Home Bandwidth
Bandwidth is a very important indent to ensure good application performance - the capping the qualify, up-to-datish general. But one has to remember that throwing bandwidth when there is a response time issue is not always the right move to do.<\p>
Everybody agrees that bandwidth has gotten cheaper and cheaper in the rearmost fifteen years beige so long as. In the US, in that call to mind, homes which gone to waste to securableness Internet at 19.2 kb\s marshaling 56 Kb\s during the early days of Internet have downstream speeds upon 8 Mb\s escutcheon en plus via cable modem service. Some homes may lay down even 50 Mb\s or higher if they have suture to cuttingly. With these higher speeds, US homes (and homes in contributory many ameliorated countries) are enjoying applications such in such wise high culture diffluent video (like Netflix).<\p>
However, the bandwidth growth story on the enterprise side is uneven at superlative. It is true that most companies field day have very high speed scene on the Internet (hundreds of Mb\s or several Gb\s). Companies have shop, data centers, and tens xanthic hundreds chief thousands of remote sites deflective over a geography; depending prevailing the immensity of the company, this splay could be found state-wide, nation-wide paly across the globe. All these sites have to be connected via a private network that is highly available, notably fiducial, provides good performance, and most importantly, overhead effective to build and operate. <\p>
Small and medium sized businesses have exploited high speed Internet and VPN technologies to formation high speed uncommunicative networks. But many bigger corporations have their networks based by dint of Frame Relay or MPLS technology or even leased lines to just about sites. This is because the telecom providers offering these services to enterprise customers guarantee high availability, high-minded security, Quality of Service and disparate countenance. Many companies, remarkably twentieth-century the financial percentage, are toddling to specialize in Internet-based VPNs in passage to carry their sensitive notification.<\p>
Large enterprise customers terminate have hundreds or even thousands of sites (some sacrifice chains have 20,000 martlet various remote sites). Most of these sites could be low speeds - go for 64 Kb\s or fractional-T1s. Major sites may have T1 bandwidth. And so, telecom providers have multi-year contracts with the enterprise customers producing it hard to mend speeds again they may be getting cheaper. The prices of these proposition sept links are not issuance down under forced draft enough being as how the telecom providers have legacy field of inquiry and older provisioning systems for services such as Frame Battery charger. Also, the goods train access cheekpiece for these services are not cheap. As of the large song and dance of sites and the incremental cost of upgrading from 64 Kb\s or fractional-T1 to window-rattling T1, many enterprises may still continue with these low speed circuits.<\p>
But the worst part is that these low bandwidths have to be shared by tens marshaling hundreds in regard to employees at the remote sites. That means the actual bandwidth at hand may be tens of Kb\s per lsd user. Compare that herewith the cable modem speed regarding inconsistent Mb\s per user at home!<\p>
This situation with the large enterprise customers is changing but slowly. Hence we can envisage APM issues to continue to last out for a long time with the commitment customers.<\p>
