Korean Financial Institution Equips Data Center for Software-Defined Networking

The National Credit Union Federation of Korea (CU) needed to upgrade its network to improve stability and performance while adding support for virtualization and software-defined networking (SDN).

“For a financial institution like CU, our top priority is the stability of the network. We introduced equipment from Juniper Networks to improve stability, and also to deliver the performance required to support virtualization solutions, guarantee high throughput and scalability, and ensure compatibility with new technologies.”

Park Soon-Yeong, Head of the Information Planning Team, IT Planning and Management, National Credit Union Federation of Korea

Overview

A nonprofit cooperative financial institution, CU manages assets worth US$60 billion through 906 credit unions and 1656 branches in Korea. Its main businesses include universal banking, savings, lending, and mutual insurance for union members. CU deploys powerful IT systems to run its operations.

Business Challenge

CU had an aging network that couldn’t meet the demands of a modern IT environment. Failing equipment started to affect the stability of applications, and equipment maintenance contracts had expired. The ever-growing volume of online transactions put additional strain on the network.

Technology Solution

CU upgraded its entire data center network with Juniper gear. It deployed EX Series switches for the high-performance core, campus aggregation, and end-of-row capabilities. MX Series routers support up to 40 10GbE ports per slot, providing greater density, scalability, and service agility for improved network performance. SRX Series firewalls provide enterprise-level security and advanced threat intelligence.

Business Results

Juniper solutions have boosted the health of CU’s systems, including its electronic banking, test networks, backbone connectivity, the Internet, and training center and data center applications. The new high-performance network supports virtualization and SDN technology, which will help CU handle ever-increasing workloads and traffic efficiently.

“The network has been operating smoothly without any failure since the new equipment was commissioned. There is no problem in terms of traffic monitoring and control. Everything is running so well that we no longer have to pay special attention to network quality management.”
