How Do Businesses Scale Their Bandwidth Needs?

onebadmutha asks: "I'm technology admin for a very rapidly growing company. We've gone from a fractional T-1, to supplementing that with a snappy DSL line, and now we're running out of reasonable options. I've looked at routers that load-balance, but do so horribly. I've considered splitting up my network users to use several incoming DSL lines, only to be confronted with intranet accessibility issues. None of these provide the kind of redundancy and control that I'd like, and certainly not with a nice pleasant UI that doesn't cause me great grief. I've looked at Open Source router distros (like routerOS, and others) and I've looked at using the full gamut of Microsoft madness. How do other businesses solve this problem of scaling bandwidth needs, without completely unlimited budgets for redundant OC-48 runs?"

  1. Speakeasy Bonded T1? by El+Cubano · · Score: 4, Interesting

    I'm not sure if you are in an area where you can get Speakeasy service, but htey allow you to bond up to four T1 lines. I have no experience with the service, but I understand that it is cheaper than a fractional T3 and they provide you with hardware that does it for you transparently. I don't know if there are other service providers that have something similar, but it seems like a good idea.

      I currently work at a communications company (VoIP, IP, PBX, etc.) and I would suggest that before IT managers dish out money for connections, they sit and analyze traffic patterns and do some QoS, policy based routing before kicking out money for a faster connection. Many companies dish out unnecessary money for faster connections when all they have to do is creative filtering beforehand. You take out 20 audio streamers and I guarantee you some of those bottlenecks won't be an issue. I used to work in a small office with about 40 employees. I had a business cable connection with 5mb speed and ran VoIP services, Internet services, etc. without issues. I also set up some cache servers and streamlined what went and came in first, to make sure business came first no matter what. Best thing to do before ordering a faster connection is to do an analysis of the current architecture and go from there.

      MRTG can create bandwidth charts for individual ports on most Cisco kit. Run it for 24 hours and then drill-down through the gear to find out who the abusers are.

      You could also install SNMP on the workstations themselves and track it back that way.

      Disable any unused ports and lock active ports to specific MAC addresses to stop the "laptop freeloader" from sucking bits on a rogue PC.

      Finally, start blocking all the ports for incoming and outgoing traffic. Open 443 and 80 for outgoing and then wait for people to call. Open ports on a per-user basis. Workers need department head approval. Dept heads need C*O approval.

  2. Dark fiber Ethernet service, or fractional DS3 by Anonymous Coward · · Score: 5, Insightful

    That's how real tech companies do it. If you can get Yipes, Cogent, AboveNet, or some other dark fiber provider to serve you Ethernet service, that's the cheapest way to get a lot of bandwidth (10-100Mb/s range). If you can't, then you get a fractional DS3. Most real providers will let you dial the bandwidth up and down reasonably, so you could start out with a 5-10Mb/s circuit and grow from there.

    Bonding T1s and DSL is neat and all, but if your business actually depends on the Internet working, go with one really good fat pipe and then maybe a thin one (T1 or so) as a backup. Don't mess with complex setups. Complex = new ways to fail.

      i can't belive he asked slashdot.. there are plenty of forums out there deticated to this type of stuff.

      Why is it every time someone asks a legitimate IT question on /. the poster is ridiculed with the above statement. Every. Single. Time. I for one think /. is a GREAT place to ask questions like these. Unless you've been the 'jack of all trades' IT guy at a small company, you have no idea what it is like. You're expected to know EVERYthing. Sure - there are forums all over the place dedicated to this specialty or that specialty. And if he was a network admin only, he likely would read those forums every day.

      I think /. is a great place to ask questions like these. Sure you have trolls and ACs who sometime suggest silly solutions. But you also have a LOT of hardened geeks and IT types who have been around the block a few times who make good suggestions. Already here I've seen 3 or 4 solid solutions that he can now consider and do more research on to see which fits his company best.

      Asking /. a question is not a sign of a n00b or bad IT person. What better place than one of the biggest techie readerships on the Internet to ask questions. I find many Ask Slashdot threads to be very informative, filed away for 'future use'

      At least you followed up the standard 'I can't believe he asked /.' with an actual, you know, answer.

      OK, move along nothign to see here. I had to waste a little Karma anyway.

    Well, at my company, we were recently faced with the same dillema.
    There are a couple of options available, though. Although my organization appears to be a bit larger than yours, we've decided to utilize a spare T1 that simply sits there for disaster recovery purposes with Policy Based Routing (We're an all Cisco network, although this can be done on a variety of platforms, including Linux..) This directs traffic from a certain IP (and possibly port, I believe) to a specific interface, so that important data (Citrix, etc) has access to our main pipes while web traffic gets the shaft, so to speak. It uses policy maps to do so; I'm relatively noobish to IOS so maybe someone else can shed some light on this.

    I'm hopefully certain you have explored QoS and are currently implementing it, but even QoS has limits.
    I'm pretty sure a combination of the 2 methods listed above should take care of you. As a network admin, I could care less if web traffic gets dropped on a cheap DSL or cable connection.

    Just my 2c, hope it helps ;)

  4. What exactly do you need? by dereference · · Score: 4, Insightful
    Your "requirements" seem to be all over the map. If you want redundancy, that's one thing. If you want simply to scale, that's quite another thing. If you want partitioning, that's yet a different problem.

    Then, ask yourself what kind of traffic you are handling. If you're looking at users surfing the web, you probably needn't be overly concerned with load balancing; if you're receiving tons of inbound traffic to your servers, on the other hand, not only do you need load balancing, but you probably also need to seriously consider co-location solutions for your servers.

    The adminstrative traffic is typically a much lower priority in most companies. I don't know how many users you're talking about, or what they're doing, but most small companies just live with a single (full) T1 until they absolutely need to bond another T1 (where "need" is subject, but should be kept in check, especially given that last bit about not having unlimited funding).

    I guess this is not much of an answer, but these are all important questions you need to be asking yourself well before seeking specific answers. I'm not sure where you're coming from, and I don't mean to accuse you of anything, but taking the approach that you'll know the right answer when you see it is usually flawed from the start.

    In all honesty, after looking over the intouchtechnical.com site, I'm going to go out on a limb here and tell you that you need to find which of your techs is running bittorrent all the time and either teach him how to set upload and download limits or cut him off entirely. As others have said, your posting is all over the map. You openly dismiss more than a few technologies that work quite well in competent hands. You mention fractional T1s, DSL, and OC48 as if you don't even know what they are. It really sounds like you aren't qualified to be the technology admin for a company whose business revolves around providing tech support to other businesses. Hate to say it, but that's what I see from where I'm sitting.
