Concurrent Multipath Transfer: Scheduling, Modelling, And Congestion Window Management, Thomas Daniel Wallace

Electronic Thesis and Dissertation Repository

Known as smartphones, multihomed devices like the iPhone and BlackBerry can simultaneously connect to Wi-Fi and 4G LTE networks. Unfortunately, due to the architectural constraints of standard transport layer protocols like the transmission control protocol (TCP), an Internet application (e.g., a file transfer) can use only one access network at a time. Due to recent developments, however, concurrent multipath transfer (CMT) using the stream control transmission protocol (SCTP) can enable multihomed devices to exploit additional network resources for transport layer communications.

In this thesis we explore a variety of techniques aimed at CMT and multihomed devices, such as: packet …

Network Neutrality Or Internet Innovation?, Christopher S. Yoo

All Faculty Scholarship

Over the past two decades, the Internet has undergone an extensive re-ordering of its topology that has resulted in increased variation in the price and quality of its services. Innovations such as private peering, multihoming, secondary peering, server farms, and content delivery networks have caused the Internet’s traditionally hierarchical architecture to be replaced by one that is more heterogeneous. Relatedly, network providers have begun to employ an increasingly varied array of business arrangements and pricing. This variation has been interpreted by some as network providers attempting to promote their self interest at the expense of the public. In fact, these …

Innovations In The Internet’S Architecture That Challenge The Status Quo, Christopher S. Yoo

All Faculty Scholarship

The current debate over broadband policy has largely overlooked a number of changes to the architecture of the Internet that have caused the price paid by and quality of service received by traffic traveling across the Internet to vary widely. Topological innovations, such as private peering, multihoming, secondary peering, server farms, and content delivery networks, have caused the Internet’s traditionally hierarchical architecture to be replaced by one that is more heterogeneous. Moreover, network providers have begun to employ an increasingly varied array of business arrangements. Some of these innovations are responses to the growing importance of peer-to-peer technologies. Others, such …
