One More Bit is Enough
TLDR
We design and implement a simple, low-complexity protocol, called variable-structure congestion control protocol (VCP), that leverages only the existing two ECN bits for network congestion feedback, and yet achieves comparable performance to XCP, i.e., high utilization, negligible packet loss rate, low persistent queue length, and reasonable fairness.

On the capacity improvement of ad hoc wireless networks using directional antennas
TLDR
In arbitrary networks, due to the reduction of the interference area, the capacity gain is proven to be √2π/α when using directional transmission and omni reception when both transmission and reception are directional. Expand

The ERICA switch algorithm for ABR traffic management in ATM networks
TLDR
This paper describes the "explicit rate indication for congestion avoidance" (ERICA) scheme for rate-based feedback from asynchronous transfer mode (ATM) switches. Expand

Analytic models for the latency and steady-state throughput of TCP tahoe, Reno, and SACK
TLDR
We present analytic models to estimate the latency and steady-state throughput of TCP Tahoe, Reno, and SACK and validate our models using both simulations and TCP traces collected from the Internet. Expand

Vehicular Traffic Density State Estimation Based on Cumulative Road Acoustics
TLDR
This paper considers the problem of vehicular traffic density estimation, utilizing the information cues present in the cumulative acoustic signal acquired from a roadside-installed single microphone. Expand

A Transport Protocol to Exploit Multipath Diversity in Wireless Networks
TLDR
We propose a multipath transport protocol, based on a carefully crafted set of enhancements to TCP, that effectively utilizes the available bandwidth and diversity provided by heterogeneous, lossy wireless paths. Expand

TCP rate control
TLDR
This paper presents TCP rate control, a new technique for transparently augmenting end-to-end TCP performance by controlling the sending rate of a TCP source. Expand

Building blocks for mobile free-space-optical networks
TLDR
We propose a new optical antenna design that employs spherical antennas covered with transmitter and receiver modules for maintaining optical links even when antennas are in relative motion. Expand

Multicast instant channel change in IPTV systems
TLDR
We propose a multicast-based approach using a secondary ldquochannel change streamrdquo in association with the multicast of the regular quality stream for the channel requested, which has several performance benefits including lower bandwidth consumption even during flash crowds of channel changes, lower display latency (50% lower), and lower variability of network & server load.
