IBZL - infinite bandwidth
Bandwidth (computing)
In computer networking and computer science, bandwidth, network bandwidth, data bandwidth, or digital bandwidth is a measure of available or consumed data communication resources expressed in bits/second or multiples of it .Note that in textbooks on wireless communications, modem data transmission,...

 (NGA) broadband is promoted strongly by policy makers as underpinning future economic growth. There is however a lack of examples of the ways that NGA will be used or of the sort of innovations that may come about as a result of widespread access to NGA. A parallel can be drawn with the advent of first generation broadband which arguably created the conditions for the success of innovations such as Wikipedia

) to explore the potentially novel applications of NGA and provide some ideas as to the key components of the future inter-networked landscape.

Next Generation Access (NGA)

While there is no universally agreed definition of what qualifies a network to be considered ‘next generation’, three elements are usually considered essential:
  • NGA will provide a significant increase in the transmission speeds available to the domestic or small-business end-user. The speeds cited vary widely from 25 Mbps (e.g. What is Digital Region? 2009) to over 200 Mbps. The ‘Digital Britain

    ’ report refers to ‘next generation service up to’ 40 Mbps, and more recently UK ministers have referred to 50 Mbps and faster. To put this in context, in early 2010, Google (Google, 2010) announced a plan for experimental community networks operating at 100 Gbps.
  • In contrast with currently widespread ADSL technologies, it is generally assumed that NGA will offer a step-change in upload as well as download speeds, reflecting the demands of increasingly user-generated content. For some, NGA bandwidth should be symmetrical, though others have a more relaxed view (e.g. OFCOM

     2009).
  • NGA is widely taken to offer improved ‘quality of service’ (QoS). QoS here is taken to mean not only service reliability and availability, but also indicators of network performance including latency (the time taken for data packets to travel from source to destination), jitter (the variation in latency among data packets) and data loss (the loss of data packets due to network congestion). Latency, jitter and data loss are important aspects of the usability of applications such as internet telephony or video, in addition to ‘raw’ bandwidth.

IBZL as a way to develop NGA

The Infinite Bandwidth, Zero Latency (IBZL) initiative was designed as a contribution to innovation by identifying new applications that will be made possible by NGA as it evolves and that may contribute to the continuing development of innovative digital industries. 'Infinite bandwidth' and 'zero latency' are not meant literally; they are a shorthand for networks where bandwidth and latency cease to be limiting factors. IBZL addresses a gap in policy and strategic thought, where relatively little attention has been given to what kinds of novel application are made feasible by networks which are relatively free of speed and latency capacity constraints. The IBZL process is intended as a means to explore and speculate on potential future technologies. To facilitate the process the Imagine methodology was adapted and applied as a form of future workshop for deep reflection on possible scenarios (numerous examples of this kind of work exist, but see for example: List 2006)

There have been two IBZL workshops held in Manchester

IBZL outcomes

The workshops produced ideas that will be further developed. Five of these are briefly summarised below.

‘Always on social space’ - virtual spaces in which the connection is always on/perpetual, supporting the kind of occasional, informal, spontaneous, real-time social encounters (‘collisions’) that happen when people are co-located, between people living and working remotely. This would not only allow a new level of remote working and collaboration but also the sense of living in proximity with friends and relations could transform the lives of older people who need to stay longer in their homes as the population ages.

‘Intelligent matchmaking’ – bringing suppliers and consumers together optimally for business, social and educational interactions. Behind this would be a thorough analysis of organizations, products and people, made possible next generation networks, in order to synthesize high quality informational and other connections.

‘Real artisans in a virtual world’ - the networked production of artefacts by artisans in multiple locations. Next generation technology could support real-time collaborative generation of product ideas followed by the process of design, development and distributed fabrication. This could turn the conventional trading pattern on its head with artisans in the developing world crafting products for “3D printing” in the developed world, effectively re-engineering (or at least, challenging) current craft value chains.

Peer-to-peer processor time-sharing - projects like SETI@home use the spare processor capacity of millions of personal computers to process batches of number-crunching tasks, co-ordinated among volunteers by a central ‘master’ application. Next generation networks could allow real time peer-to-peer sharing so that when an application needs additional capacity for processor-heavy tasks like video rendering it could have access to effectively limitless extra computing power.

Latency mapping - the evolution of next generation networks will be uneven, resulting in a ‘geography of latency’ and the disruption of ‘simultaneous time’. The kinds of networked application that are feasible between two network locations will be a function of a range of factors including spatial distribution, network infrastructure and the network of relationships between service providers. Latency maps would be an enabling tool to identify the kinds of applications possible within/between, technical/geographic, or commercial spaces.
