Site rolling out new web-based product over https with 128kbps footprint per user. Site has 100Mbps link already at 40% utilisation, and expects 700 concurrent users of new app. The figures result in a saturated line. Could upgrade site link, but backhaul only 100Mbps from non-21CN POP so waste of time.
One of many possible approaches ..... howver PPRuNe is not the place for technical debate over this.
But yes, as batninth pointed out earlier.... if you've got one of those scenarios with a lot of dupe data floating around then sure, it's probably a great solution.
