A State-of-the-Art Social Security Network

ZUS was struggling to keep up with providing new social security services and meeting customer demand for new delivery services including video. Their current network could not meet these new demands and they turned to Huawei for help.

In an uncertain global financial environment and with an aging population, European governments are increasingly under pressure to improve the quality of their public services while keeping costs under control. Increasingly governments need to make use of real-time information to make the right decision at the right time.

The Polish Social Insurance Institution (ZUS) has worked to stay ahead of these challenges while delivering a comprehensive set of public services through local branches across every province and county in Poland. The IT leaders at ZUS were not only struggling to meet increasing customer demand for services, they were also struggling to meet an increasing desire for multi-media services such as online video.

Won the bid for ZUS network reconstruction

ZUS decided it was time to upgrade its network infrastructure and implement new technologies that can handle/withstand heavy network traffic.

In 2010, Poland invited several of the world's leading telecom vendors to bid on the construction of a state-of-the-art network for ZUS. Huawei aligned with SEQUENCE (a local distributor/channel partner), and the two companies jointly submitted a bid, with Huawei providing products and solutions and SEQUENCE responsible for the solution delivery and service.

At the beginning stage of the project, Huawei's prime objective was to address the needs of ZUS through concrete field tests on its network architecture and in-depth analysis of service requirements. Huawei proposed a solution based on its S series switches and AR routers. The solution was designed to have every operating branch of ZUS directly connected to its network headquarters through AR routers, with aggregation and core nodes using the S series switches. Each S series switch provided a maximum of 480 10GE interfaces. This solution allowed bandwidth expansion, improved service reliability, and was backed by hardware-based OAM or BFD technology which could detect faults within 10 ms, ensuring fast switchover. The proposed solution delivered high bandwidth and performance with low fixed and operating costs. Huawei exclusively won the bid for ZUS network reconstruction on June 30, 2011.

Helped ZUS to smoothly upgrade their network

Close to 95% of ZUS's network was built on traditional multimode fibers, which transmitted data at speeds of up to 10 Gbit/s data at a maximum distance of 30 m. Not only was network performance limited over these lines causing traffic bottlenecks, but the 30 m transmission distance fell short of the network capacity required by ZUS. Installing OM3 fiber was considered the best option, but ZUS dad not have the additional capital required to lay down fiber. To find alternatives, Huawei immediately developed a contingency plan to reduce investment costs.

Huawei's solution involved deploying a highly customizable and flexible Long Reach Multimode (LRM) functionality built on its proprietary S series switches. The LRM enables faster data-transfer rates of up to 10 Gbit/s at a maximum length of 220m over OM1 fiber using cutting-edge electronic dispersion compensation (EDC) technology. This not only met ZUS's transmission distance issue but also smoothly upgraded their network connection from 1000M to 10G.

Huawei strives to be extremely customer-oriented and seeks to find creative solutions to its customers' problems. Huawei's commitment to delivering long-term customer value has won the trust and confidence of ZUS..
