Long flows contribute huge volumes of traffic over inter-datacenter WAN. The flow completion time (FCT) is a vital network performance metric that affects the running time of distributed applications and the users’ quality of experience. Flow routing techniques based on propagation or queuing latency or instantaneous link utilization are insufficient for minimization of the long flows’ FCT. We propose a routing approach that uses the remaining sizes and paths of all ongoing flows to minimize…

Optimizing Inter-Datacenter Tail Flow Completion Times using Best Worst-case Routing

TLDR
This paper discusses Best Worst-case Routing (BWR), which aims at optimizing the tail completion times of long-running flows over inter-datacenter networks with non-uniform link capacities, and investigates two heuristics, BWRH and BWRHF, which use two different upper bounds on the worst-case completion times for routing.

DeepRoute: Herding Elephant and Mice Flows with Reinforcement Learning

TLDR
Inspired by recent advances in AI to manage resources, DeepRoute is presented, a model-less reinforcement learning approach that translates the path computation problem to a learning problem and is shown to improve average network path utilization to 30% and potentially reduce possible congestion across the whole network.

MAC ADDRESS CLONING TECHNIQUE RESULTS

TLDR
MAC filtering is more effective in wired network, since it is more difficult for attacker to identify authorized MAC address, which can also be used in the process of exploiting security of a system.

Datacenter WAN traffic consists of high priority transfers that have to be carried as soon as they arrive alongside large transfers with pre-assigned deadlines on their completion (ranging from

Online multicast routing with bandwidth guarantees: a new approach using multicast network flow

TLDR
A multicast tree selection heuristic that is based on the idea of deferred loading of certain critical links that, if heavily loaded, would make it impossible to satisfy future demands between certain ingress-egress pairs is developed.

Inside the Social Network's (Datacenter) Network

TLDR
The contrasting locality, stability, and predictability of network traffic in Facebook's datacenters are reported on, and their implications for network architecture, traffic engineering, and switch design are commented on.

B4 and after: managing hierarchy, partitioning, and asymmetry for availability and scale in google's software-defined WAN

TLDR
This paper presents the five-year evolution of B4, Google's private software-defined WAN, and describes the techniques employed to incrementally move from offering best-effort content-copy services to carrier-grade availability, while concurrently scaling B4 to accommodate 100x more traffic.

Software defined network: Future of networking

TLDR
Software Defined Networking is an emerging paradigm that separates the network's control logic from the underlying routers and switches, promoting logical centralization of network control and introducing the ability to program the network.

Software-defined networking

TLDR
Novel architecture allows programmers to quickly reconfigure network resource usage as well as provide real-time information about how the network is being used.
