Bandwidth is a major expense for most enterprises, comprising about a quarter of an average IT budget. Despite this, employees are only allocated an amazingly paltry 41K bps on average on the company network—a fraction of what they generally use at home, which often can be anywhere from 1M bps to 10M bps or more. This naturally causes consternation for employees who have high expectations for Internet connectivity based on their in-home experience and are frequently frustrated by their in-office experiences. This also affects employees negatively when it comes to both daily productivity and morale. This type of frustration also is often the case for consumer connected devices, which have been more advanced than enterprise-supplied equipment for the last decade or so. Many data center managers believe enterprises need to do something about this condition. Here are 10 common bandwidth pain points and how to deal with them on the company network. Our key resources for this slide show are Andrew Lochart, vice president of marketing and Products at network optimization software provider Mobolize, and eWEEK reporting.

 
 
 
  • Enterprise Networks Are Much Slower Than Home Systems: 10 Reasons Why

    1 - Enterprise Networks Are Much Slower Than Home Systems: 10 Reasons Why
  • Too Little Bandwidth to Start

    Most companies start out in a hole by provisioning too little bandwidth on their Internet connections. Whether due to budget limits or poor planning—not understanding users' real Internet habits and needs—most companies don't offer enough bandwidth for their users' needs. It's common for users to have less than 50K bps, a far cry from the 10M-bps broadband speeds they have at home from their cable company.

  • Software as a Service Stresses the WAN

    Companies large and small are embracing SaaS to focus their IT efforts on strategic projects and end-user support, instead of building and maintaining data center infrastructure. However, many adopt SaaS without considering the toll it takes on their wide-area network from the additional traffic.
    3 - Software as a Service Stresses the WAN
  • SaaS Adds Latency

    Not only does SaaS overload the WAN, causing slowdowns and increased packet loss, but it also adds latency by moving the data center further away from the end users, so applications can end up moving a lot slower.
    4 - SaaS Adds Latency
  • Surge in HTTP

    The shift from client-server to Web-based applications (whether on-premises or SaaS) has meant the shift to greater amounts of HTTP traffic. HTTP is a "chatty" protocol and uses a high number of round trips to get the data from the server to the browser, further exacerbating the feeling that employees get of a really slow network. Today, 57 percent of corporate network traffic is HTTP/S.
    5 - Surge in HTTP
  • Bigger Web Pages

    Web pages are getting bigger with more features, images and JavaScript. According to the HTTParchive.org, Web pages are growing 33 percent in size every year.
    6 - Bigger Web Pages
  • Needless Redelivery

    The real killer is the needless redelivery of the same Web content over and over again. Browser caches are comically small (typically 250MB), compared with both the amount of Web app and Website usage and the colossal size of hard drives today. Small caches mean that content is forced out by new content too soon, so it has to be redelivered.
    7 - Needless Redelivery
  • The Web Is Cacheable

    The redelivery of content is unnecessary because most of it is static and cacheable. It's hard to believe, but 88 percent of the average Web page is static and can—and should—be cached and re-used. A lot of the content is invisible, like Cascading Style Sheets and JavaScript, so many don't even realize it's there.
    8 - The Web Is Cacheable
  • Voice and Video

    Network congestion isn't just caused by new Web content. As companies shift to using voice over IP (VOIP) and videoconferencing, they are adding more traffic to their already overburdened WANs.
    9 - Voice and Video
  • Alternative Solutions

    A solution to slow Web-based applications and Websites in general is more caching. Today's large hard drives have room for multi-gigabyte-size caches that browsers can utilize. There's no reason browsers should have a single cache that all Web apps have to share.
    10 - Alternative Solutions
  • A Faster, Better Web

    The impact of significantly improved Web caching would be profound. Caches that are large, per-user and per-site could provide the greatest possible benefit in terms of reducing needless redelivery of content, thus eliminating large amounts of WAN traffic. Latency would also be greatly reduced—by a factor of four to fifteen, depending on conditions, because delivering content from cache is much faster than delivering it over the network.
