Exploiting the power of multiplicity: a holistic survey of network-layer multipath
The Internet is inherently a multipath network: For an underlying network with only a single path, connecting various nodes would have been debilitatingly fragile. Unfortunately, traditional Internet technologies have been designed around the restrictive assumption of a single working path between a source and a destination. The lack of native multipath support constrains network performance even as the underlying network is richly connected and has redundant multiple paths. Computer networks can exploit the power of multiplicity, through which a diverse collection of paths is resource pooled as a single resource, to unlock the inherent redundancy of the Internet. This opens up a new vista of opportunities, promising increased throughput (through concurrent usage of multiple paths) and increased reliability and fault tolerance (through the use of multiple paths in backup/redundant arrangements). There are many emerging trends in networking that signify that the Internet's future will be multipath, including the use of multipath technology in data center computing; the ready availability of multiple heterogeneous radio interfaces in wireless (such as Wi-Fi and cellular) in wireless devices; ubiquity of mobile devices that are multihomed with heterogeneous access networks; and the development and standardization of multipath transport protocols such as multipath TCP. The aim of this paper is to provide a comprehensive survey of the literature on network-layer multipath solutions. We will present a detailed investigation of two important design issues, namely, the control plane problem of how to compute and select the routes and the data plane problem of how to split the flow on the computed paths. The main contribution of this paper is a systematic articulation of the main design issues in network-layer multipath routing along with a broad-ranging survey of the vast literature on network-layer multipathing. We also highlight open issues and identify directions for future work
On Resource Aware Algorithms in Epidemic Live Streaming
Epidemic-style diffusion schemes have been previously proposed for achieving
peer-to-peer live streaming. Their performance trade-offs have been deeply
analyzed for homogeneous systems, where all peers have the same upload
capacity. However, epidemic schemes designed for heterogeneous systems have not
been completely understood yet. In this report we focus on the peer selection
process and propose a generic model that encompasses a large class of
algorithms. The process is modeled as a combination of two functions, an aware
one and an agnostic one. By means of simulations, we analyze the
awareness-agnostism trade-offs on the peer selection process and the impact of
the source distribution policy in non-homogeneous networks. We highlight that
the early diffusion of a given chunk is crucial for its overall diffusion
performance, and a fairness trade-off arises between the performance of
heterogeneous peers, as a function of the level of awareness
