P AR T I 46 Leased Line and Data Switching Networks  Competition  Domestic Fixed Communications  ●  Broadband internet access providers: kbro Co., Ltd., Taiwan Fixed Network and New Century Infocomm Tech. Co., Ltd.,  China Network System Co., Ltd.; and  ●  Leased line service providers: Taiwan Fixed Network, New Century Infocomm Tech. Co., Ltd., Asia Pacific Telecom Co.  Ltd., East Asia Netcom Taiwan, Reach Global Services Ltd., FLAG Telecom and Taiwan International Gateway Corporation.  Our primary competitors in leased line services and broadband services include:  We are required by Republic of China regulations to provide number portability and unbundled local loop access.  We are the largest domestic fixed communications service provider in Taiwan, with a market share of approximately 95.3% in  terms of customers for local telephone services, approximately 74.1% in terms of traffic for domestic long distance telephone services  in 2011, and approximately 79.2% share of the broadband internet access market in terms of customers. Three new providers,  namely, Taiwan Fixed Network, New Century Infocomm Tech. Co., Ltd. and Asia Pacific Telecom Co. Ltd., have provided fixed  communication services since June 2001. Our domestic long distance services compete with mobile services as people increasingly  use mobile handsets. We believe that the fixed line competition in Taiwan will be primarily based on price, quality of service, network  coverage and customer services, such as call centers and unified billing.  We face competition in virtually all aspects of our business.  Our data networks support a variety of transmission technologies, including X.25 protocol, frame relay and asynchronous  transfer mode technology. We have also built up our HiLink VPN that combines internet protocol and asynchronous transfer mode  technologies. The advantage of a HiLink VPN based on multi protocol label switching technology is that it can carry different  classes of services, such as video, voice and data together to provide services with various qualities of service, high performance  transmission and fast forward solution in an enhanced security network. A HiLink VPN can be accessed by an ADSL and can include  built-in mechanisms that can deal with overlapping internet protocol addresses. Therefore, the network potentially is less costly and  requires less management for business applications.  We operate leased line networks on both a managed and unmanaged basis. In addition, we operate a number of switched  digital networks used principally for the provision of packet-switched, frame relay, asynchronous transfer mode technology and  a multi protocol label switching internet protocol VPN. We have completed the construction of a digital cross connect system for  provisioning and managing voice-grade data services throughout Taiwan with a total of 50 nodes. As of December 31, 2011, we had  3,168 frame relay ports, 150 X.25 ports, 2,686 asynchronous transfer mode ports and approximately 66,655 multi protocol label  switching internet protocol VPN virtual ports.  HiNet’s total international connection bandwidth is 315 Gbps as of December 31, 2011. As we expect that internet traffic  flows to and from the United States will continue to increase, we plan to expand our bandwidth to the United States. We also plan to  increase our links to other countries, including Japan, Korea, Hong Kong, Singapore, Mainland China, Malaysia and Thailand.  approximately 1,740 Gbps as of December 31, 2011. We plan to increase HiNet’s points of presence and backbone bandwidth to  approximately 2,290 Gbps by the end of 2012.
