QoS Frameworks

As new applications start using the Internet, the requirements that they impose to the IP network are not always fulfilled. In particular time-sensitive applications such as videoconferencing, video distribution and voice have strict requirements in terms of packet loss, latency, jitter and bandwidth. This new scenario forces the network to evolve towards a model that

Multicore Architectures

Hardware designs increasingly favor multiple cores per CPU die over increased speed, resulting in number fabrication constraints. This creates a new Moore's Law in which doubling core counts every 10 months.

Modern software designs use virtualization to maximize utilization and flexibility across specific hardware implementations with efficient isolation amongst processes. These two new technology trends can be combined to enable dense efficient processing of network applications. To leverage the combination of these architectural shifts it will be necessary to use appropriate forms of loose and tightly coupled parallel algorithms and implementations.

Power

The world is shifting towards sustainability and energy efficiency. With the rise of green initiatives and carbon emission credits, markets and regulations are the first steps in a potentially massive shift in the world economy.

In recognition of these new requirements on and by governments, companies, and individual consumers, research is needed to enhance the efficiency of hardware components as well as their device-level integration, from systems power management to high-level power savings integration, and future paradigms for power efficiency in networking. We seek to catalyze creative power efficiency designs that can be enabled by the networks.

Service Infrastructure

As the Network evolves, applications we never imagined become ubiquitous and even household names. Cisco is constantly searching for these new applications so that we can add new functionality to the network. Taking this one step further , Cisco would like to sponsor research in the areas of future network based applications and services as well as the infrastructure and mechanisms needed to support them.

The goal of this initiative is to understand how the network can provide a better framework in terms of functionality and integration in today's distributed applications environment as well as to direct new research and discussions into this new model.

Optical Networking

Optical networking – specifically technology based on DWDM – has finally developed into a full networking technology with its ability to set up connections in an automated fashion. In parallel, the industry has started to integrate optical technology more closely into routers to achieve more economical core and aggregation architectures. At the same time, the ever increasing bandwidth of the Internet and new applications such as video mandate higher bit-rates per wavelength and higher spectral efficiency over the fiber, resulting in optical networks that may be harder to automate due to higher sensitivity to optical impairments.

We are seeking original applied research in the area of DWDM networking at the physical transmission layer; the control plane inside the optical layer and between it and the packet layer; and management of the optical layer and its interaction with the router.

Web X.0

With the introduction of Web 2.0 technologies, the Internet has evolved from a set of information silos into a platform for collaboration, content exchange, and application development.

Another direction is the Semantic Web, Web 3.0, whereby data will not only be represented in a human accessible format, but also in a machine accessible one. This allows for automated information search, integration, and publishing.

Routing and Addressing

The rapid growth of the Internet and the imminent depletion of IPv4 addresses are posing increasing challenges on network routing and addressing. To enhance the scalability and performance of the network, continuing studies are needed to provide efficient routing schemes and addressing methodologies. While various schemes have been proposed to address some of the issues, a satisfying and deployable solution has yet to be identified. As such, research on the problems posed by the need for a scalable routing and addressing system for the Internet is needed. Issues include (but are not limited to) the scalability of the routing system, both in terms of state (the routing table) and rate (the dynamic nature of the network), securing the routing system, and "routing system economics". Note that these issues apply to both the IPv4 and IPv6 environments.

Understanding and Improving the Human Network

The explosive growth in personalized devices, social networks, and novel user interfaces is transforming our daily lives by changing the way we interact with each other and co-exist in society. A deeper understanding of human behavior is useful to understand the technology needs of the next generation of communication networks. Cisco invites proposals which explore the broad spectrum of measuring, modeling, and leveraging human behavior, in order to develop better infrastructure to support, sustain, and enhance the Human Network.
