“…It is important to note that the link between the two switches was set up to produce varying levels of delay to provide accurate result set. The values for these were used based on the HPDMnet global testbed network [19] that was in place and being utilised for testing. The link between PSNC and Starlight has a round trip delay of 125ms, which presented a useful metric to test the system with.…”

The increase in real time ultra-high definition video services presents a challenging issue to current network infrastructures, because of its high bandwidth usage, which saturate network links. The required bandwidth is related to strict QoS requirements for digital media. There are systems in place currently to help reduce these problems, such as transcoders and application layer multicasting. However, these approaches are limited because they are usually implemented as static resources. In contrast, by using the OpenFlow based system presented in this paper, it is possible to provide a more effective approach using dynamic resources -by both optimally placing transcoders in the network, as well as by migrating them to different locations while the streaming is taking place. This migration mechanism provides a near seamless switchover with minimal interruption to the clients.

“…Consequently, an international consortium of networking researchers have established the High Performance Digital Media Network (HPDMnet), to investigate basic challenging problems in this area, to create responses to those challenges, and to implement those innovations on a global experimental multimedia testbed, based on L1 and L2 services. [21] The HPDMnet testbed was designed to support the highest capacity of multimedia streams that can be generated. This testbed is being used to investigate multiple architectures, techniques, technologies and methods that enable dynamic configuration and reconfigurations of multiple network resources.…”

For many years, experimental network research testbeds have been designed and implemented to explore theoretical concepts at scale, progressing beyond ideas that initially may have been explored through lab simulation and modeling. However, traditionally, such testbeds almost always were created for specific, highly defined projects, and they were designed to last for fairly short periods of time. More recently, network research communities have been designing, implementing, and operating new types of large scale experimental network testbeds, including those global in scope, which are intended to be long term persistent resources and can support multiple types of experiments. These testbeds reflect recent innovations in architecture and in core technologies and also the declining cost curves of basic components, a trend which is reducing the economic barriers to developing testbeds. This paper presents several key ideas motivating the creation of next generation testbeds and it describes design concepts, core technologies, and operational issues. This paper also describes a number of recent and current large scale testbeds that have been created to advance the state of communications, especially those designed to assist in providing a transition to the future Internet.
