A case for end system multicast
TLDR
We explore an alternative architecture that we term end system multicast, where end systems implement all multicast related functionality including membership management and packet replication. Expand

TLDR
We propose using coordinates-based mechanisms in a peer-to-peer architecture to predict Internet network distance (i.e. round-trip propagation and transmission delay). Expand

Improving Fairness, Efficiency, and Stability in HTTP-Based Adaptive Video Streaming With Festive
TLDR
We present a principled understanding of bit-rate adaptation and analyze several commercial players through the lens of an abstract player model consisting of three main components: bandwidth estimation, Bit-rate selection, and chunk scheduling. Expand

WF/sup 2/Q: worst-case fair weighted fair queueing
TLDR
The generalized processor sharing (GPS) discipline is proven to have two desirable properties: (a) it can provide an end-to-end bounded-delay service to a session whose traffic is constrained by a leaky bucket; (b)it can ensure fair allocation of bandwidth among all back logged sessions regardless of whether or not their traffic is.

Understanding the impact of video quality on user engagement
TLDR
We use a unique dataset that spans different content types, including short video on demand (VoD), long VoD, and live content from popular video content providers. Expand

Core-stateless fair queueing: achieving approximately fair bandwidth allocations in high speed networks
TLDR
Router mechanisms designed to achieve fair bandwidth allocations, like Fair Queueing, have many desirable properties for congestion control in the Internet. Expand

Providing guaranteed services without per flow management
TLDR
In this paper, we propose techniques that do not require per flow management (either control or data planes) at core routers, but can implement guaranteed services with levels of flexibility, utilization, and assurance similar to those that can be provided with per flow mechanisms. Expand

Packet fair queueing algorithms for wireless networks with location-dependent errors
TLDR
We identify a set of properties, called channel-condition independent fair (CIF), that a packet fair queueing algorithm should have in a wireless environment: (1) delay and throughput guarantees for error-free sessions, (2) long term fairness for error sessions, and (3) graceful degradation for sessions that have received excess service.

Efficient content location using interest-based locality in peer-to-peer systems
TLDR
We propose a content location solution in which peers loosely organize themselves into an interest-based structure on top of the existing Gnutella network. Expand
