Chunghwa Telecom's Successful Implementation of Verimatrix Technology for IPTV and OTT Disaster Recovery
Chunghwa Telecom, Taiwan's largest telecommunications company, was seeking to create a comprehensive disaster recovery solution for its IPTV and over-the-top (OTT) networks. The company had two geo-redundant data centers in Taipei and Tainan, servicing customers in the northern and southern regions respectively. The challenge was to achieve multiple layers of geographic redundancy, allowing each regional data center to failover to its respective backup regional data center, without any failover between the northern and southern regions. Each distinct user base was to be managed independently, but with synchronization of all content ingestion occurring in the northern data centers, then being synchronized with southern data centers. The company also needed to ensure that each of the data centers could failover transparently to the end subscriber in the event of a major failure or natural disaster.
