Fitting mixtures of exponentials to long-tail distributions to analyze network performance models
TLDR
This work develops an algorithm for approximating a long-tail distribution by a finite mixture of exponentials, where an exponential component is fit in the largest remaining time scale and then the fitted exponential components are subtracted from the distribution.
On dominant characteristics of residential broadband internet traffic
TLDR
Observations from monitoring the network activity for more than 20,000 residential DSL customers in an urban area find that HTTP - not peer-to-peer - traffic dominates by a significant margin and that the DSL lines are frequently not the bottleneck in bulk-transfer performance.
Towards programmable enterprise WLANS with Odin
TLDR
Odin, an SDN framework to introduce programmability in enterprise wireless local area networks (WLANs), builds on a light virtual AP abstraction that greatly simplifies client management and supports WPA2 Enterprise.
Dynamics of IP traffic: a study of the role of variability and the impact of control
TLDR
It is shown that scaling analysis has the ability to extract relevant information about the time-scale dynamics of Internet traffic, thereby, it is hoped, making these techniques available to a larger segment of the networking research community.
Data networks as cascades: investigating the multifractal nature of Internet WAN traffic
TLDR
A simple construction based on cascades that allows for a plausible physical explanation of the observed multifractal scaling behavior of data traffic and suggests that the underlying multiplicative structure is a traffic invariant for WAN traffic that co-exists with self-similarity is provided.
Live wide-area migration of virtual machines including local persistent state
TLDR
By combining a block-level solution with pre-copying and write throttling, it is shown that an entire running web server can be transferred, including its local persistent state, with minimal disruption.
Potential benefits of delta encoding and data compression for HTTP
TLDR
It is shown that delta encoding can provide remarkable improvements in response size and response delay for an important subset of HTTP content types, and that the combination of delta encoding and data compression yields the best results.
Panopticon: Reaping the Benefits of Incremental SDN Deployment in Enterprise Networks
TLDR
The design and implementation of Panopticon is presented, an architecture for operating networks that combine legacy and SDN switches that suggests that when as few as 10% of distribution switches support SDN, most of an enterprise network can be operated as a single SDN while meeting key resource constraints.
Tradeoffs for packet classification
TLDR
An algorithmic framework for solving the packet classification problem that allows various access time versus memory tradeoffs is presented and gives the best known lookup performance with moderately large memory space.
