Postal Savings Bank of China is the fifth-largest commercial bank in China. As postal finances and services grow, the performance and functions of postal backbone transmission networks are, and will continue to be, increasingly challenged. To ensure business continuity and improve customer service and satisfaction, the State Postal Bureau of China realized it needed to rebuild its inter-provincial postal backbone transmission networks. Currently, these transmission networks include postal comprehensive networks, postal finance networks for disaster recovery, and financial IP networks and comprehensive IP networks that are set up on the transmission networks. The IP networks are strictly isolated from each other.
Postal Savings Bank of China wanted to separate its IP postal comprehensive networks from its IP postal financial networks. To do this, it needed to build backbone networks that would enable both networks to run from two centers: a national center and a disaster recovery center; the backbone would also have to regulate the overall network structure. This would lay a foundation for subsequent development. A solution required network deployment divided into the following stages:
· Adjust the backbone network structure between the national center and the disaster recovery center in the headquarters;
· Construct and manage 31 provincial backbone transmission networks countrywide;
· Plan necessary IP addresses for the national backbone transmission networks;
· Plan security management for the nationwide networks; and
· Plan nationwide network management, as well as operation and maintenance management.
H3C created a custom-tailored solution for Postal Savings Bank of China, constructing a high-performance, highly reliable and secure backbone network that would satisfy the bank’s business development needs for at least five years. The following H3C devices contributed to the solution:
Construction of the financial backbone networks standardized the backbone network structure, facilitated operation and maintenance management, enhanced risk management, guaranteed business continuity and increased protection of mission-critical data. As a result, disaster recovery capability was greatly increased, readily meeting financial industry regulation requirements.
