Hello IRTF community,

As part of a follow-up activity since the last IRTF meeting in Prague on Cross Stratum Optimization work, there will be a workshop on Cloud Computing and Cross Stratum Optimization held on June 7-8, 2011.

The workshop will be held in ETRI's facility in Daejeon, Korea.  Please see the details of this workshop below. We will look forward to your participation and contribution for this workshop.
Please contact us should you have any question on the workshop: Taesang Choi<mailto:tschoi@etri.or.kr> or Young Lee<mailto:leeyoung@huawei.com>.
Best Regards,
Taesang & Young


Call for Participation

Cloud Computing and Cross Stratum Optimization Workshop

ETRI, Daejeon, Korea,
June 7-8, 2011

Background

Cloud computing provides a variety of services allowing end-users, from individual to enterprises, to access to large pools of storage resources, computational resources and various application services.  There are many ways in which these services are provided to end-users, ranging from individual software applications (Google docs, Salesforce.com) to the allocation and use of thousands of raw computing resources geographically distributed around the world.  Data centers provide the physical and virtual infrastructure in which cloud computing applications and services are provided.

Since cloud computing and the data centers used to provide application services are distributed geographically around a network, many decisions made in the control and management of application services, such as where to instantiate another service instance or to which data center out of several a new client is assigned, can have a significant impact on the state of the network. Conversely the capabilities and state of the network can have a major impact on application performance.

Currently application decisions are made with very little or no information concerning the underlying network used to deliver those services. Hence such decisions may be sub-optimal from both application and network resource utilization, and from the achievement of quality of service objectives.  Among the top ten obstacles to the adoption of cloud computing identified according to Ambrust[1] et. al., over half have significant involvement of the network: 1. availability/business continuity; 3. data confidentiality and auditability; 4. data transfer bottlenecks; 5. performance unpredictability; 8. scaling quickly; 9. reputation fate sharing.

As more application and services are envisaged to be offered via cloud computing and data centers, it is critical to have an overall architectural model   from both the application stratum and the network stratum points of view; define key interfaces among the entities involved in cloud computing, data centers and the networks supporting them; and provide a next generation  architecture that integrate select aspects of  cloud computing, data centers, and networks to improve service continuity, performance predictability/guarantees, scalability and manageability.

Cross-stratum optimization is referred to combined optimization in the application and network stratum that aims to provide joint application/network resource optimization, responsiveness to quickly changing demands from/to application to/from network, enhanced service resilience (via cooperative recovery techniques between application and network) and quality of application experience (QoE) enhancement (via better use of existing network and application resources).

This workshop aims to explore the challenges and issues faced by cloud computing and data center integration with networks. Among the key areas of investigation to be discussed in the workshop are as follows:

*         Cloud/network integration architectures and subsystems
*         Use cases, business models and requirements for cloud/network integration
*         Control/management issues for cloud/network integration
*         Network virtualization and its impact for cloud/network integration
*         Application-aware transport network
*         Network-aware application/cloud computing
*         Joint application/network reliability and security
*         Experimental/trial experience
*         Scalability
*         Joint/shared performance and fault monitoring
*         Multi-domain issues

The goal of this workshop is to promote the research interest in cloud/network integration and to start a new research activity in the IRTF community. The workshop organizers are interested in receiving contributions that supports this goal.
Workshop Style
The workshop's main focus will be on the discussions of technical topics. Each presentation will be given about 40 minutes and 15 minutes of discussion.  Interactive discussion will be encouraged.
In order to keep the group at a manageable size, participants are required to submit a position paper as an expression of interest. The authors of accepted papers will be invited to submit power point presentations and attend the workshop although under special circumstances remote access capability via video conferencing will be provided.
Important Dates
The position papers (an abstract with no more than two pages) must be submitted by May 20th, 2011.
Position papers will be reviewed by the program organizers and an invitation to the workshop will be sent to one of the paper authors. At the latest, invitations will be distributed by May 25th, 2011.
Invited contributions (power point slides) must be submitted at latest by June 3rd, 2011.
All contributions can be submitted to: cso-workshop-prep@cccso.net<mailto:cso-workshop-prep@cccso.net>.
Workshop Technical Committee
Members of the workshop technical committee are as follows:

  *   Tae Sang Choi (ETRI)
  *   Young Lee (Huawei)
  *   Volker Hilt (Bell Labs)
  *   Kohei Shiomoto (NTT)
  *   Francisco Javier Jimenez Chico (Telefonica)
  *   Oscar de Dios Gonzalez (Telefonica)
  *   Greg Bernstein (Grotto Networking)
  *   Ning So (Verizon)
  *   Andrea Fumagalli (University of Texas, Dallas)
  *   Tae Yeon Kim (ETRI)
  *   Dan Li (Huawei)
  *   Dong Sik Yun (KT)

Workshop Logistics
This one and a half day workshop will take place on June 7-8, 2011 in ETRI facility, Daejeon, Korea:
161 Gajong-Dong, Yusong-Gu, Daejeon 305-350 Republic of Korea

l    How to get to ETRI facility from Incheon International Airport
The best way to get to ETRI from Incheon airport is by airport limousine bus.  It will take you to Daeduk Doryong bus stop which is 5 minutes away by Taxi from ETRI.  The journey will take about 3 hours from airport to bus stop.
An alternative way is to take KTX express train from Seoul train station to Daejeon train station and take taxi from it to ETRI.
l    Lodging/hotel information
Two local hotels are recommended.
Spapia Hotel: http://www.hotelspapia.com/english/index.php
Yusong Hotel: http://www.yousunghotel.com (Korean web page only)
Reservations with corporate discount rate are available.  You can contact Taesang Choi<mailto:tschoi@etri.or.kr> (email: choits@etri.re.kr<mailto:choits@etri.re.kr>; tel: +82 42 860 5628) for the reservations.
