Drift can affect systems in different ways. For communications systems, the impact can be significant. Consider a wireless device like a cell phone, tablet, or embedded sensor. As the frequency drifts over time, the device will begin to both experience and cause RF interference problems as it drifts into other frequency bands. It may experience synchronization issues with other devices, reducing performance and reliability.
1. Decentralization of the Internet: the emergence of national and regional Internet Exchanges facilitates private peering
arrangements by increasing number of ISPs’ access networks edges in one central location.
2. Commoditization of IP Interconnect prices (falling IP transit, CDN or router costs) led to substitutability of IP Interconnection
products and countervailing powers in the IP Interconnection value chain.
3. Proliferation of Content Delivery Networks: Content & Application Providers leverage the increased value of their Internet
content by building proprietary caching server parks or, alternatively, using independent, commercial CDN services that are
located close to the ISPs’ access networks.
Still, the majority of Internet traffic is progressively being concentrated to a limited number of large Content & Application Providers
and a few wholesale carriers. In 2013, 35 networks carried 50% of all Internet traffic in North America, down from 150 networks in
2009. The concentration of IP traffic is a major evolution in the IP Interconnection value chain, and has the potential to influence the
negotiating power among connectivity stakeholders and affect the current equilibrium in the Internet ecosystem.

Consider the case where a workstation in Building A is sending data to another network device in Building B. The ground potential of each building will be a function of the impedance of its ground system and the current flowing through the ground. The data line, in addition to carrying data, is also connecting together the ground systems of the two buildings. If the ground potentials of Building A and Building B are different, a ground current flows in the data line. This is known as a ground potential difference. The voltage level of the data signals is increased or decreased by the ground potential difference, causing data transmission errors.
