**Program Area Presentation**
- Energy Sciences Network (ESnet)

**In coordination with**
**Thomas Ndousse**
**Mar****y**** Anne Scott**

## ESnet

- ESnet is a high-speed data communications network which allows Department of Energy (DOE) scientists and collaborators worldwide to use unique DOE research facilities and computing resources independent of time and location with state-of-the-art performance levels.

**Contribution of Program Element to Overall ASCR Strategic Goal**

- Building an Integrated Network
- Environment for Distributed Science

## ESnet

- Short term 1-3 yrs
- Backbone and site upgrades to allow the DOE high impact science programs to achieve their goals
- Accommodate 100% growth in traffic each year
- Long term 1-5 yrs
- Implementation of new network technologies and topologies for projected future applications requirements
- Keep data flowing — provide DOE scientists with the network capabilities they need to support their science

**Planning horizon for Program Element**

## ESnet

**Connectivity**
- Distributed Network performance measurement and analysis
- High performance transport protocols
- Multicast and secure group communication
- High speed, ubiquitous,and  reliable backbone infrastructure
- Quality of Service (QoS) services
- New protocol implementation – IPv6
**Collaborative technologies**
- Access Grid Technology
- Data conferencing
- Ad- hoc H323 (IP based) conferencing
- Multi platform Video conferencing services
**Security**
- Public Key Infrastructure
- System scanning and intrusion detection tools

**Areas that the Element currently invests in **
**and **
**Research areas that rely on the ESnet infrastructure support**

## ESnet

- Energy Sciences Steering Committee (ESSC)
- Energy Sciences Site Coordinating Committee (ESCC)
- Incorporates emerging services as they mature into ESnet
- Internet Engineering Task Force (IETF) partnerships
- Outreach
- Interagency Large Scale Network (LSN) membership
- Multi agency/Vendor Joint Engineering Task (JET)Force membership
- Workshops, conferences, and publications

**How does Program Element transfer knowledge or provide services to application scientists?**

## ESnet

**Provides end-to end connectivity that is not available over the commodity Internet**
**Community involvement, organization and support (ESSC, ESCC)**
**Operated and managed by user community (scientists)**
**Strong collaboration with the network research and middleware programs**
**Single national and international identity for DOE research networking**
**Many long term working relationships with national and international peers**
**Long track record and extensive experience in meeting the ever expanding programmatic requirements within budget**
**Significant leveraging of overall effort and cost savings with central support staff on 24x7 basis**
**Responsive to the special demands of DOE research community**
**QoS, jumbo frames, scavenger service**
**CCC/MPLS for NNSA**

**Program Element Strengths**

## ESnet

- Cultural inertia
- Programmatic networking needs requirements projections
- Success metrics for production networks conflicts with success metrics for R&D networks
- “Networking will be there” mentality
- Technology barriers
- Perceived low cost of providing high bandwidth services
- Need it yesterday – not enough time for technology to catch up
- Unrealistic performance expectations from current technology
- Less than mature router/switch code
- Organizational barriers
- Ineffective integration of program responsibilities and accountabilities moving from research to production
- Long time frame for moving of new technologies into production network

**Program Area Weaknesses**

## ESnet

- Abundant optical capacity exists in core networks to develop cost-effective agile network infrastructures to support high-impact science applications
- Develop terabit networks and services for interconnecting data analysis and management centers associated with Petascale computers
- Growth in “grids” will create requirements for new central services
- Apply research network technology improvements to accelerate the development of advanced networking services
- Develop additional distributed security services to protect the network and provide user security without cumbersome user services

**Program Element Opportunities**

## ESnet

- Programmatic needs will outstrip network projected growth rate and budget
- “Adequate Networking will always be there” assumption by program elements
- Long-term planning for facilities and programs
- Security policies may neutralize needed performance advances
- Potential reduced longevity of at-risk telecomm vendors due to current market conditions
- Highly specialized network technologies beyond scope of industry

**Program Element Threats**

## ESnet

- End-to-end performance
- Multi-domain and site network performance improvements
- Development of reliable Ultra high-speed transport protocols
- Distributed Network measurement and prediction
- Cyber security
- -	scalable distributed authentication and authorization systems
- Minimal impact on the user and network
- Integrated testbeds and production networks
- Network research to accelerate advanced technologies
- Experimental deployment of high-impact applications
- Ability to use the production network to scale network research testbeds with minimal impact on production
