An article by Josee Loudiadis [pictured], Director of Network Intelligence, Alcatel-Lucent, covers the "signaling spikes that can overwhelm available signaling capacity, undermining the customer experience and the operator’s reputation with it" and analyzes the signaling behavior of several common applications.
"There are three kinds of “signalasis”: microbursts that can be measured in seconds, extended bursts that can last minutes to hours, and suddenly sustained signaling growth where signaling jumps significantly at one point in time and continues to increase over weeks and months. Facebook’s 60% jump on Nov 2012 is an example of the latter"
- Extended bursts Viber outage:
|GGSN experiencing 92% jump in signaling|
for 4 ½ hours during Viber outage
- Microbursts: Microsoft Exchange and iOS:
|GWs subjected to 36% signaling microburst at midnight|
due to iOS-based Microsoft Exchange
