....they should be able to determine the optimal way of distributing themselves and the distribution may have to be changed during execution. The problem of adaptation has received a fair bit of attention, especially in the area of multimedia, e.g. network aware streaming of audio [6, 2] and video [5, 14, 7, 9] data. The performance of distributed computing applications tends to be much harder to characterize, making it more di#cult to make them network aware. In this paper we introduce two di#erent mechanisms for making an application network aware, one based on a performance model of the application ....

....avoidance (e.g. TCP IP [8] are an important example of adaptation to network conditions. In terms of applicationspecific adaptation to network conditions by network aware applications, several groups have focused on continuous media tra#c streams, e.g. network aware voice [6, 2] and video [5, 14, 7, 9, 10] streaming applications. There has been some work on non multimedia network aware applications, although the network aware decision making is typically at a coarse level. One example is having storage intensive applications (e.g. Web browsers) select the most appropriate server, based on the ....

....to adapt based on implicit feedback, e.g. TCP interprets dropped packets as a sign of congestion [19] Recently, several applications have been developed 15 that adapt to the bandwidth and latency variations of the underlying network. One class of examples are Internet based video and audio tools [17, 18, 15, 6, 31]. Another class of examples consists of distributed computations modifying the granularity of the computation in response to network status [27, 29] The adaptation policies used in these applications are ad hoc and application specific. Interpreting implicit feedback from the network is ....

The basic architecture is illustrated reassemble render packets frames coding units network decode Fig. 1. Receive data path processing in vic. in Figure 1. Packets containing encoded video arrive from the network and are reassembled into encodingspecific framing units, which are decoded by ....
