                        Capacity Sharing Workshop
                        -------------------------

co-located with CoNEXT 2012, December 10, 2012, Nice, France.

Internet data traffic continues to grow rapidly.  The challenge that operators 
face, especially in the mobile Internet, is to support more subscribers with 
higher bandwidth demands. 

Therefore, operators need to seek for new technologies to efficiently utilize 
the available network resources, in particular, this concerns resource 
allocation and flow management. In wireless networks, the problem is 
particularly relevant due to the inherently limited resources, which render a 
simple "throwing bandwidth at the problem" solution impossible. The higher 
rate of optical technology in access networks introduces the potential for 
capacity sharing problems to move closer to the core, while passive optical 
networks move sharing problems closer to the end-user (more like cable and 
radio access networks). Data centers typically employ yet another type of 
network with different characteristics -- and different tools for capacity 
sharing. 

Addressing this topic correctly is not trivial as there are different 
interests to consider: operators naturally want to be able exercise control 
on how the network is used, avoid service disruptions and account for network 
usage. Users are interested to use different applications and expect a 
certain level of service quality, consistent experience etc. Many 
applications today are provided by so-called over-the-top (OTT) providers -- 
in conjunction with web-services, smart-phone applications etc. These 
applications and the corresponding platforms are important drivers for 
innovation and sources of revenue -- although there is controversy over 
whether enough revenue is directed into capacity growth. Still, application 
providers are interested in their application working with sufficient 
quality. In addition, there is regulation that can impose additional 
requirements in some markets, such as availability requirements, network 
neutrality etc.

The objective of this workshop is to bring together researchers in the area of 
transport protocols, system designers of fixed and mobile access networks, 
and their applications to advance the state of research on capacity sharing. 
We solicit contributions on the state-of-the-art, results of ongoing 
research, open issues, trends and new ideas. 

Topics
------
Topics of particular interest include, but are not limited to

 * Context-aware resource allocation & cross-layer adaptation
