Solving latency by increasing bandwidth?

    What role does bandwidth play in reducing latency and where is how do you address in the blueprints (if at all)?

  • Snarkier

    This latency question occurs fairly often in my discussions with other architects.  For this discussion, latency is  defined as the time it takes a network packet to travel between its source and its destination on a network.  This path will involve several devices including routers and the source and destination servers. 

    Therefore, latency is affected by the physical distance between source and destination, no matter how much bandwidth is available --the distance traversed affects latency. If several routers and network devices encounter the packet on its travels, that will increase latency as well. Increased bandwidth will not overcome the physics of distance.

    Net: You only effectively solve these latency issues by moving applications closer to where the users are in metro areas (what is also known as the digital edge).  

    Here's a good article about the impact of latency upon bandwidth http://www.ihiji.com/latent-latency

    Hope this is helpful!
    I have practiced pattern based design for over 20 years and am passionately curious about how technology affects our lives.

    Very helpful, thanks for the correlation between distance and bandwidth usage

    MWarchitect -- This blog by   smadden just came out.  Seems relevent to your initial post. enjoy!


    The question that network architects must answer is: “How much latency can your company afford?”  The answer is: “It depends on how much it impacts or differentiates your business.” For example:

    • Amazon saw that for every 100 ms of latency, they lost 1% in sales.
    • Google found that when an extra .5 seconds was added to the time it took to generate a search page, traffic dropped by 20%.
    • A stockbroker could lose $4 million in revenues per millisecond if an electronic trading platform is 5 ms late in completing the transaction.
    • Online advertisers have a window of approximately 100 ms to place real-time bids for ads in programmatic advertising systems before they lose out on potential revenue streams.
