The cache-and-forward (CNF) architecture has recently been proposed as a "clean-slate" solution for efficient content delivery in the future Internet. The CNF architecture is based on the concept of hop-by-hop transport and in-network storage of content. In this paper, we investigate a gateway centric method for efficient content caching and routing in the CNF network. In this method, a...
Large swings in the demand for content are commonplace within the Internet. Although multistage interconnection networks (MINs) are fairly flexible in handling varieties of traffic loads, their performance considerably degrades by hotspot traffic, especially at increasing size networks. As alleviation to the tree saturation problem, the prioritizing of packets is proposed leading to a scheme that...
We explore the interaction between content distribution and traffic engineering. Because a traffic engineer may be unaware of the structure of content distribution systems or overlay networks, his management of the network does not fully anticipate how traffic might change as a result of his actions. Content distribution systems that assign servers at the application level can respond very rapidly...
The Border Gateway Protocol governs the overall routing in the Internet. With the time, it has been overloaded with functions which is was not initially designed for. The main example is Traffic Engineering. Internet Service Providers need to adjust the traffic on their peerings and in absence of a better alternative, use Trial and Error techniques based on manipulating the Autonomous System Path...
