CHAPTER 5 NETWORK ROADMAP EVOLUTION The first response in such a scenario would be to determine the impacts on the network's KPI due to such a flash crowd event, which could possibly include the following for an LTE network: Availability impact. New subscribers may not be able to latch on to the network in the area covered by cells subject to the flash crowd. Dependability impact. Existing subscribers may face diminished or unreliable service in terms of download or other operations on ongoing requests. Performability impact. Existing subscribers may face a huge drop in performance in terms of ensured speeds in the network during the event. Some of the conditions for handling of such situations in a related domain of video service is covered by Wenan Zhou et al. Remedial actions to this in our scenario could involve the following: Detection that a flash crowd event has occurred in real time Distribution of incoming requests to other parts of the network (neighboring cells) or to interrelated systems like 2G or 3G as a fixed rule until the flash event has passed Reducing QoS in a planned manner across all ongoing services in the network region under the impact Continually measuring system performance and taking additional measures like engaging alternate service providers to share some requests based on existing sharing arrangements kept in place for such exigencies Selection of suitable steps to be taken would depend on and be determined by the resilience management function discussed earlier, which would control the actions and help the system handle the challenge.
