  1. Link aggregation (LAG) could be used either for more
    capacity or for redundancy. If, for example, you would like to protect your GigE
    UNI with LAG, you would connect two Gig ports using LAG, but you will not exceed
    the one Gig bandwidth. In this case if one of the link fails, all the traffic
    will still go through the other link.     

    With regard to your second question, there are many protection
    methods; slide 10 on my presentation (slide 26 on the combined deck) describes
    few of them.

  2. Doug, it may seem to some listening to the webinar that some of the issues your brought up seem like problems that have not yet materialized in Latin America, is this a matter of time or can the region avoid them entirely? Meaning, we might not suffer them at all.

    • It is true that the DNS only has visibility into IP address which (especially in mobile) is a constantly changing ID. However, since Nominum has built a complete architecture that has access to more than simply DNS information, we have the ability to merge queries with User IDs pulled from RADIUS for example. So, we can help our customers manage policy via the DNS down to the individual user level.

    • Actually, it’s quite the opposite. With the customers we’ve worked with over the last 12-18 months, we’ve seen fairly significant infection rates in LATAM. While mobile operators may not be seeing it, I’d argue that it’s because bot-related threats aren’t currently being tracked closely in those networks. According to our research, the mobile threat is definitely real, but not quite to the same degree as fixed networks… yet. However, we also see it as being one of the fastest growing segments of bot activity. Bots are very real worldwide, and especially in LATAM.

  3. Hi Doug,

    How can Nominum use DNS to track mobile users when the DNS only has access to IP address and those change very rapidly?Thanks!

  4. Hi Rami,

    Why should any operator move multi CoS, is it uses today the high CoS (real time CoS) for all types of traffic?

    • Rafael,

      Here are few reasons to move to Multi CoS:

      –         
      One CoS network is not
      scalable.

      –         
      One CoS backhaul, even the
      highest CoS, would not provide the best performance –  According to our study only around 8% of the
      mobile traffic is very sensitive to delay variation and needs real time CoS. By
      running all you traffic on a single CoS, that sensitive traffic is subject to
      higher delay variation.

      –         
      Multi CoS improves the performance
      of the sensitive traffic and provides better bandwidth utilization.

      –         
      LTE already has the tool to
      optimize the traffic with multi CoS

      –         
      When using microwave radio
      for backhaul, multi CoS allows you to run adaptive modulation which increase
      your availability for the high priority traffic.

  5. to Rami:

    Could you explain us how the link aggregartion help to improve the resiliency? I’ve used  it just to have more capacity aggregating links just like an array but I can’t undestand how it could be a UNI resiliency.

    Beyond this specific resiliency, could you further extend the explanation of the other escenarios  of resiliancy or  maybe, could you  tell me where  could  I find detailed information related?

    Thanks in adavance.
