re: Analyst Fingers NSN Server for Verizon's 4G Fail
The detail isn't there to know for sure, but given the Diameter signaling environment here, this could be a problem that a policy exchange controller (PEC) could solve. Many companies are introducing these new products (including my own) to secure and scale the Diameter signaling environment that is prevalent in LTE and IMS.
One role a PEC plays is load balancing, routing and performing admission control for Diameter, including in front of HSS and PCRF servers.

Certainly overload control capabilities are not part of the design of an HSS. This applies both to IMS and EPC access. Dozens or hundreds of MMEs can easily flood an HSS in many situations. For EPC access a Policy Exchange Controller layer is able to control signaling overloads from MMEs and protect the HSS.

Seemed that there were no ball to be dropped in this game because there were no ball! LTE is suppose to be a packet data technology,and as such all the necessary backup servers should be in place.Isn't strange that the network went down despite very few devices that are LTE enabled were on it? The thing is, Verizon and others were in a mad rush to build-out their LTE infrastructure to prove that it was better than WiMax,but who gets the last laugh? However, in the fulness of time we will see which technology will be laughing all the way to the bank!
