—Worldwide Interoperability for Microwave Access (referred to as WiMAX) is a MAC and physical layer wireless communications technology for outdoor broadband wireless coverage. In collaboration with the Clemson University Police Department, we have deployed an 802.16d WiMAX network that operates at 4.9 GHz at Clemson University. In this paper, we present the(More)
High Performance Routing (HPR) is an enhancement to IBM's Advanced Peer to Peer Networking (APPN 1) protocol that improves its performance and reliability. In an HPR network, the Rapid Transport Protocol (RTP) is used for end-to-end data transfer. 2 RTP provides a reliable, in-order delivery service using a selective repeat protocol as the end-to-end error(More)
Since the first community antenna television (CATV) system was deployed in 1948, cable technology has advanced at an astounding rate. Today, multiple service providers (MSOs) are competing with telephone companies to deliver the long sought 'triple play' of voice, video and data to residential and business premises. Upstream data rates have progressed from(More)
— This paper proposes a cloud-based architecture for enhancing the performance and capacity of vehicular networks of potentially multiple different wireless technologies. The approach addresses the well-known limitations of today's vehicle-initiated as well as base station-assisted handoff solutions; the former is reactive, therefore slow and inefficient,(More)
—A critical component of subscriber management in a DOCSIS-based cable access network is the buffer management strategy that is in operation at the upstream service flow queue located in the cable modem. The strategy must contend with conflicting goals: large buffers might be required to ensure TCP flows can utilize available bandwidth, however large(More)
Executive Overview 2 • We've all heard about Netflix. • We know Netflix consumes a significant portion of downstream bandwidth. • We know that a standards-based approach for adaptive HTTP-based streaming is likely to be widely deployed. Executive Overview 3 • But do you know …. • What happens from the user's perspective when many DASH flows compete for(More)
—The concept of fairness in assigning access to network resources has been well defined in traditional networks. With the introduction of channel bonding into the DOCSIS 3.0 standard, where different flows may not have access to the same set of resources, the definition of fairness becomes less clear. In this paper we will investigate the application of(More)
