While we tend to think about the Internet as a diverse interconnected network of networks, the truth is that a selection of hyper giants like Google, Facebook and Microsoft drive most of the traffic. The rise of hyper giants impacts the networking industry in several ways:

  • The core is evolving. The traffic is increasingly exchanged between the large content providers as well as regional and local Internet Service Providers at the Edge and through Content Distribution Networks (CDN).
  • Applications continue to migrate to the web. Arbor notes that web traffic is regaining momentum and now shows greater growth than peer-to-peer traffic.
  • Service providers are changing their business models and service offerings to adapt to the new environment. Tier one international transit providers have started to offer cloud computing and content distribution services. In addition, national ISPs continue to broaden their offerings in new areas.

As the traffic pattern on the Internet shifts, new innovations are called upon to make content distribution more efficient than today. Intelligent caching integrated to the switching infrastructure is one area of special interest. The first major inroads for this technology took place a few years back when the first generation of IPTV services were rolled out. Some access systems integrated local caching to allow for decreased zapping times, and frames to be resent in case of packet loss in the last mile. These systems were built to support a specific IPTV service, managed and controlled by the ISP. To support content providers and global services, these capabilities must be enhanced to support other services and evolving business models.

More information on Internet traffic patterns can be found in the press announcement.
