Resilient service ecologies for IPTV: Using RESTful services to enable resilience

Delivering TV services via internet protocols over high-speed connections is commonly referred to as IPTV (internet protocol television). Similar to the app-stores of smartphones, IPTV platforms enable the emergence of IPTV service ecologies in which 3

party developers provide services to consumer that add value to the IPTV experience. A key issue in the IPTV ecosystem is the resilience of its services. This paper focuses on the issues related resilience in digital service ecologies. Starting with a review of resilience research in the area of biological ecologies we focus on differences and solutions for digital ecologies. Within the context of service ecologies we compare SOA and REST as design options and their impact with respect to resilience.
