I am inclined to agree with Wes that DMM is hard enough already without having clouds arising in the horizon. Cloud computing and such has a premise but I have hard time seeing how that would drive distributed mobility management. I rather see it as opposite.. shifting the mindset again towards centralized data centers.
On the other hand if we just think mobility management entities as VMs, spawning new functions here and there does not differentiate from what we are already trying to figure out - from mobility protocols point of view. The difference would be that the possible gateway is not a physical box anymore. The herding of VMs is not what we are tasked to do. - Jouni On Sep 26, 2012, at 11:08 PM, Behcet Sarikaya wrote: > On Wed, Sep 26, 2012 at 2:48 PM, Wesley Eddy <[email protected]> wrote: >> On 9/26/2012 3:40 PM, Behcet Sarikaya wrote: >>> I am talking about 3GPP entities like Serving Gateway and PDN Gateway >>> being placed in the cloud. >> >> >> Sure, so they run on a VM somewhere ... what's the technical >> challenge that this poses?
