Quality of Broadband services

Description

Quality of a broadband services refers to the measures of the broadband technical performance. These measures consists of the bandwidth available and the latency of the network at the end-user side, which are issues of major relevance in the Internet environment. Nowadays USA after being for almost a decade the leading country on Internet services, especially broadband, is facing a major debacle due to not properly planned investment which resulted in low quality services, such as the so called broadband subscription which offer a tiny 436Kb of bandwidth, while European average bandwidth is around 5MB up to the 100MB of the average Japanese household.

Therefore, in order to support the increasing demand (see Figure 1) of services such as IPTV, Internet TV and mobile TV, the global infrastructure on which Internet is based will require large investments so that the final users will positively experience these services. Hence, a satisfied consumer will be willing to try more innovative services and will introduce it in his own life creating a so called network effect concerning the adaptation.

Enablers

• Increasing use of new (high quality) type of connection: Fiber to the Home (FTTH) Hybrid fiber wire (HFW) WiFi Wi-Max
• Full implementation of IPv6 (Internet Protocol V6)

Inhibitors

• Unexpected growth of the Internet traffic
• Slowdown of investment in infrastructure

Paradigms

Before: Up to couple of years ago Internet connections were often narrow-band, limiting the online experience to web-browsing, reading email and slow download through P2P software.

After: The Internet has become a multimedia channel, through which is possible stream contents from audio to video. This is just the begin of what will be in the future internet through a progressive improvement of the quality of Broadband services in order to support HD video, high quality contents and real-time online storage.
