TCP-Friendly Rate Control (TFRC) was originally designed for multimedia streaming applications where continuous data was available at the sender. However, TFRC is not well-suited to the variable rate traffic presented by many modern adaptive media codecs. One way to counter this deficiency would be for the sender to continue to transmit at the media rate(More)
The Internet is inherently a multipath network—for an underlying network with only a single path connecting various nodes would have been debilitatingly fragile. Unfortunately, traditional Internet technologies have been designed around the restrictive assumption of a single working path between a source and a destination. The lack of native multipath(More)
"The Internet is for everyone" claims Vint Cerf, the father of the Internet via RFC 3271. The Internet Society's recent global Internet survey reveals that the Internet should be considered as a basic human birth right. We strongly agree with these and believe that basic access to the Internet should be made free, at least to access the essential services.(More)
Scoped-flooding is a technique for content discovery in a broad networking context. This paper investigates the effects of scoped-flooding on various topologies in information- centric networking. Using the proposed ring model, we show that flooding can be constrained within a very small neighbourhood to achieve most of the gains which come from areas where(More)
This article discusses the danger of a growing digital divide between rural and other areas. It presents broadband as increasingly necessary for the delivery of information, health, education, business, social security, public and leisure services. Access to broadband has become vital for rural communities to participate in a progressively digital economy(More)
The Datagram Congestion Control Protocol (DCCP) is a new IETF-defined transport protocol for Internet multimedia. The DCCP Congestion Control Identifier 4 (CCID4) was specifically designed to support the stream of small packets generated by applications such as Voice over IP (VoIP). This uses equation based congestion control. The long round trip delay when(More)
It is well known that Africa’s mobile and fixed Internet infrastructure is progressing at a rapid pace. A flurry of recent research has quantified this, highlighting the expansion of its underlying connectivity network. However, improving the infrastructure is not useful without appropriately provisioned services to utilise it. This paper measures the(More)
Enabling universal Internet access is one of the key issues that is currently being addressed globally. However the existing Internet architecture is seriously challenged to ensure universal service provisioning. This technical report puts forth our vision to make the Internet more accessible by architecting a universal communication architectural framework(More)
Community networks owned and operated by local communities have recently gained popularity as a low cost solution for Internet access. In this paper, we seek to understand the characteristics of Internet usage in community networks and provide useful insights on designing and improving community networks in rural areas. We report the results of a(More)
