Routers in the network core are unable to maintain detailed statistics for every packet; thus, traffic statistics are often based on packet sampling, which reduces accuracy. Because tracking large ("heavy-hitter") traffic ...

Today’s Internet achieves end-to-end connectivity through bilateral contracts between neighboring networks; unfortunately, this “one size fits all” connectivity results in less efficient paths, unsold capacity and unmet ...

Traffic classification and distinction allows network operators to provision resources, enforce trust, control unwanted traffic, and traceback unwanted traffic to its source. Today’s classification mechanisms rely ...

Deploying software-defined networking (SDN) at Internet Exchange Points (IXPs) offers new hope for solving long-standing problems in interdomain routing. SDN allows direct expression of more flexible policies, and IXPs ...

Most users of home networks have experienced the intense frustration that comes with diagnosing poor performance. Even determining something as simple as whether a performance problem lies with the ISP or somewhere in ...

Operators make hundreds of changes to a network’s router and switch configurations every day—a painstaking, error-prone process. If the network configuration could instead encode different forwarding behavior for different ...

This paper introduces event-driven network control, a network control framework that makes networks easier to manage by automating many tasks that must currently be performed by manually modifying low-level, distributed, ...

Network security is typically reactive: Networks provide connectivity and subsequently alter this connectivity according to various security policies, as implemented in middleboxes, or at higher layers. This approach ...

This paper presents an analysis of the performance of residential access networks using over four months of round-trip, download, and upload measurements from more than 7,000 users across four ADSL and cable providers ...

In broadband access networks, one application may compete for the bandwidth of other applications, thus degrading overall performance. One solution to this problem is to allocate bandwidth to competing flows based on ...
