2 1 Trends of Enterprise Network 1 Under the circumstance of economic globalization, enterprises expand gradually and have branches distributed sparsely. It is a great challenge for enterprise staff, especially the nonprofessional persons, to manage branch networks and ensure normal service operation. Gartner forecasts that the IT expenses of most enterprises will be 35% more than IT department's budget by Working Style Before 1990s Fixed Office data After 2000 Early mobile office voice + data Now BYOD video + voice + data Don t know No 8% Future 27% 65% Yes 65% enterprises accepted BYOD access globally. - Information Week 2011 Figure 1 Architecture of BYOD network solution Employees' work styles are changing. Employees move more often over a wider range. Mobile office, BYOD, and emergency communication become a trend, allowing employees to access enterprise networks anytime and anywhere. Limited by IT investments, an enterprise needs to build a multi-play bearer network. However, wider network coverage and stronger mobility impose more threats to enterprise networks. All these require higher security of branch networks. InformationWeek estimated that in 2011, 65% of enterprises are using or willing to use the Bring Your Own Device (BYOD) work mode. BYOD allows an employee to use any type of terminal anywhere, anytime to access an enterprise network. Wired and wireless sections of a campus network must be seamlessly interconnected so that employees can enjoy the same online experience from any terminal.

3 2 To address the problems and challenges facing the branch networks, Huawei provides the converged and easy branch network solution. This solution can help enterprises build reliable and practical remote branch networks and achieve high-efficient operation of enterprise services. Core Experience Huawei One Net High-quality mobile network Security Efficiency 2 Value Solution Product Handy services Secure mobility Easy management 10G campus network solution, easy and converged branch network solution, combined wired-wireless solution, network access control(nac) solution, desktop cloud solution Switch Router Firewall WLAN GPON Figure 2 Architecture of BYOD network solution

4 2.1 BYOD Infrastructure Network Solution The infrastructure network of the BYOD network solution uses multi-layer, modular, redundant architecture.

Each layer has clearly defined functions and a stable topology, making the network easy to expand and maintain. 2)Modular design: Each module corresponds to an enterprise department, facilitating fault location. Network topology changes in one department do not affect other departments. 3)Redundant design: A two-node redundant design makes the network more reliable without significantly increasing the maintenance workload. Too much redundancy is difficult to maintain.

5 2.2 BYOD Network Solution G&WLAN Converged The AR supports dual wireless uplink access, deployment simple and fast. 3G is relying on Huawei deep accumulation in the wireless field, interconnection and carrier networks.

Preferred backup of wired link: Solve the issues such as link cost, time, and complexity in deploying the second cable, wireless link has become the first choice of backup links. Reliable access with double wireless links: Completely wireless the 3G/LTE way to solve the connection problem. WLAN Downstream: Flexibility to adapt to a variety of complex mobile scene. Wireless access in Fixed place: Including branch offices, gas stations, and financial outlets. Wireless access anywhere: Including emergency rescue, logistics vehicle terminal. Unable to deploy wired link: Mining, field exploration and other occasions.

6 2.2.2 AP high-density coverage, High-speed intelligent The Huawei converged and easy branch network solution has the following advantages in terms of mobility: 5 1) Huawei has rich experience in the wireless communications industry and has developed industry-leading wireless technologies. Huawei APs support intelligent antennas, built-in antenna array, dynamic user detection, and sector radio transmission to reduce co-efficiency interference. These technologies increase the coverage area of APs by 20% c and improve the access throughput by 20% compared with similar products. Band width Throughput comparison Huawei vs. other vendors Users 2) Huawei WLAN products use the thirdgeneration chips and industry-leading technologies to support high-density user access. The third-generation chips use more precise weighted algorithm to provide more stable radio signals for wireless terminals. Thanks to Huawei's experience in 3G technology development (Huawei has obtained more than 200 patents for core wireless technologies since 2010), Huawei converged and easy branch network solution integrates the Wi- Fi network with 3G network seamlessly.

Huawei intelligent network management system greatly simplifies WLAN network deployment and management.

7 2.2.3 Wired/Wireless Integrated Huawei BYOD network solution implements integrated wired/wireless access. Wireless access controllers (ACs) are integrated on switches and the same security policies, network devices and user management policies are deployed for wired and wireless users. Wireless and wired networks are seamlessly interconnected, reducing network management and maintenance costs.

Huawei also provides a wide variety of energy-saving PoE switches and intelligent wireless access products. The wired and wireless networks use the same AAA policy server and same security devices. The highly efficient unified network management system simplifies management and reduces O&M costs.
