| Outline of the talk |
| Goals and major directions of the project | |
| Software architecture, API, SOAP/XML, some details | |
| How Lambda Station works - use cases | |
| Status and the near-term plans | |
| The goal of the project... |
| Target: last-mile problem between local computing facilities and alternate WAN paths | ||
| Strategy: develop a network path selection service to interface production storage & computing facilities with wide-area network paths. | ||
| alternate network paths for high impact data movement | ||
| selective forwarding on a per flow basis | ||
| graceful cutover and fallback on path changes | ||
| on-demand from applications (authentication & authorization) | ||
| current implementation based on policy-based routing & including the support of DSCP marking | ||

| Summary – Current Status |
| Functional system deployed at FNAL, UNL, & Caltech | |
| Application LS awareness - dCache/SRM | |
| Primitive protocol to request a DC via ESNet/Internet2 | |
| Successful demonstration SC05, I2 FMM, SC07 | |
| (Sort ofÉ) Production use with US CMS Tier1, Tier2s at UNL and Caltech | |
| Flow analysis to invoke a Lambda Station ticket based on observed traffic |
| Plans |
| Improve code to make production quality | |
| Support multi-platform clients | |
| Enhance protocol for interaction with OSCARs/ESnet & DCN/I2 | |
| Improve distribution package | |
| Develop management/configuring tools | |
| Interface with monitoring system | |
| Documentation | |
| Large-scale data recover via DCN |
| One week after I2 FMM demo, UNL lost their Tier-2 data cache | ||
| 50TB Data recovered by transfer FNAL Tier-1: | ||
| Largely via Internet2/ESNet Dynamic Circuit | ||
| Completed in 32 hours | ||
