Background

• A well-known transnational electronics manufacturing enterprises, they need to establish a subsidiary in China, and to build a high-security, high dependability internal communication system. It includes data system, voice system, wireless system, Security & Protection system. And they can access parent company network and external network effectively as well.

Solution

■ High Performance

• The system use high-performance network equipments. It includes high-performance switches, firewalls, PBX and network acceleration equipment etc.

■ High Dependability

• The WAN use MPLS-VPN dedicated circuit or internet circuit to connect to parent company in Japan. The two circuits back up for each other and the related equipments also back up each other in this way. They use these circuits for data communications and VoIP communications (intercom). We set up a firewall between the internal network and internet to ensure the dependability of communication.
• The LAN composed of a hierarchical back-up network to protect the network scalability and anti-impairment, and use the dynamic routing protocol to improve network efficiency.
• We used a relatively high safety standard IEEE802.11g for wireless LAN design, to achieve a seamless communication.

■ High Relevance

• The TV conference system not only make the day-to-day meeting with remote site easier and utility but also makes the high-quality visual communication come true.
• The voice phone system used VoIP technology to reduce the international telephone charges and domestic telephone charges greatly. In addition, the wireless PHS makes the company internal calls easily.
• WAN acceleration system used an advanced acceleration equipment. It can optimize the bandwidth, latency, TCP transmission and application layer protocol with highly-efficient.
• IC time and attendance access control system, a professional uni-card system design, keep the customer’s daily routines safely and in order.
• Surveillance System We chose advanced and excellent surveillance equipment, it is an important component in security & protection system.

■ Leading Technology

• When we design network and choose network equipment for our customer. We are not only consider our customer’s requirement sufficiently but also integrate some leading technology in network security.

Effectiveness after Import

• After the subsidiary’s information system project finished, the company’s communication into a safe and efficient track. This information system provides a stable, efficient and safe environment for manufacture. Further more, it provide a dependable communication environment for customer’s business development in china
