Internet bottleneck

Internet bottlenecks are places in telecommunication networks in which internet service providers (ISPs), or naturally occurring high use of the network, slow or alter the network speed of the users and/or content producers using that network. A bottleneck is a more general term for a system that has been reduced or slowed due to limited resources or components. The bottleneck occurs in a network when there are too many users attempting to access a specific resource. Internet bottlenecks provide artificial and natural network choke points to inhibit certain sets of users from overloading the entire network by consuming too much bandwidth. Theoretically, this will lead users and content producers through alternative paths to accomplish their goals while limiting the network load at any one time. Alternatively, internet bottlenecks have been seen as a way for ISPs to take advantage of their dominant market-power increasing rates for content providers to push past bottlenecks. The United States Federal Communications Commission (FCC) has created regulations stipulating that artificial bottlenecks are in direct opposition to a free and open Internet.

The technical reasons for Internet bottlenecks are largely related to network congestion in which the user experiences a delay in delivering or accessing content. The bottlenecks can occur naturally, during high network use, or artificially created by owners of the network, generally considered to be ISPs, in order to prevent the network from experiencing overload.

The network demands of users continues to grow and with it so do the pressures on networks. The way current technologies process information over the network is slow and consumes large amounts of energy. ISPs and engineers argue that these issues with the increased demand on the networks result in some necessary congestion, but the bottlenecks also occur because of the lack of technology to handle such huge data needs using minimal energy. There are attempts being made to increase the speed, amount of data, and reduce power consumption of the networks. For example, optical memory devices could be used in the future to send and receive light signals working much faster and more efficiently than electrical signals. Some researchers see optical memory as needed to reduce the demands on the network routers in data transmission, while others do not. The research will continue to explore possibilities for greater network bandwidth and data transfer. As data consumption needs increase, so will the need for better technology that facilitates the transfer and storage of that data.

Deep packet inspection (DPI) may also be used to address network congestion through recognition of a specific set of protocols, services, or users. ISPs may then manipulate the bandwidth allocation for those groups by reducing it to maintain the network stability and available bandwidth for the entire network.

Network congestion or Internet bottleneck generally occurs and is felt by users in homes and businesses. This is what is known as the last mile of transmission, which is when there is not enough bandwidth available for individual users to access the content they want. Everyone is attempting to use the bandwidth at the same time creating an Internet traffic jam.

In terms of public policy, Internet bottlenecks and/or network congestion has largely been nested within the network neutrality debate. Network neutrality is the notion that ISPs and content providers need to be regulated in order to maintain fair speeds and access to content for all Internet users. Internet bottlenecks had been perceived as useful facets of network management, but ISPs have throttled specific types of uses of their networks that have little to do with network management and more to do with network neutrality.

New regulatory rules were established by the FCC in order to enforce fair network management practices by ISPs. The rules were established on September 23, 2011, and took effect November 20, 2011. This new set of regulations has three primary rules:

Of these rules, set up by the FCC, only number 2 and number 3 apply to network bottlenecks. Network bottlenecks represent a specific part of that policy discussion in which ISPs are able to create network flows that are slower for competitors possibly leading customers to go to another website that is more easily accessed, which gives the parent or children companies of the ISPs an advantage. Thus, in the FCC's rule number 2 and 3 there are specific requirements that ISPs do not discriminate or restrict services to those companies who offer competing services similar to the ISP's services.
