Welcome the Next Generation Grid-enable Collaboration Marek.Domaracky@cern.ch Marek Domaracky
EVO • Introduction • The EVO concept • Koala Marek Domaracky
VRVS/EVO Project Timeline Version v0.4 • 1995 Caltech/CMS group started development of a full Web • based user interface for videoconferencing. • In January 1997, pushed by strong demand from the LHC • experiments, the Caltech/CMS group started a production • prototype Web-based service named the Virtual Room • Videoconferencing System (VRVS). • During 1998-2000 VRVS was widely recognized by Research • and Education Communities worldwide. It became a core • technology for IP-based video & multimedia services in Internet2. • July 2001 VRVS is the first system to supportmultiple protocols • (Mbone, H.323, MPEG) for collaboration over IP networks. • February 2003, 1stre-architecture of the VRVS System (97% Code • redone) – User Authentication, Database, AccessGrid Support, .. • December 2006, Release of the next generation collaboration system EVO, a “Globally Distributed Self Managed End- to-End Real-time Infrastructure” v1.0 v2.0 v2.5 v3.0 v4.0 3
Current Usage of VRVS • Currently: • 28,000Users Registered from 140 Countries, more than 1,400 worldwide meetings involving more than 7,500 different users who start VRVS sessions per month • It is the first Very Large Distributed System (using the Grid concept) deployed and used today in Production. 4 Marek Domaracky
HENP usage since January 2004 From January 2004 to July 2006 , at least one VRVS meeting was booked with one of the following keywordsin the title. Representing a minimum of 72 different Physics Experiments that use or have used VRVS: ALICE , ALTA , AMS, ASACUSA, ATHENA, ATLAS, BaBar, Belle, BES, CASA, CAST, CDF, CESR, CLEO, CMS, COMPASS, D0, DELPHI, DIRAC, E325, E94, EDM, EMU, FLARE, FOCUS, GEANT, GEM, GENIUS, GLAST, H1, HARP, HESS, HiRes, ICECUBE, ILC, ISAC, KamLAND, KOPIO, L3, LAND, LEGS, LHC, LIGO, Linear Collider, MACRO, MAGIC, MECO, MINOS, MIPP, Muon, NEMO, OPERA, OWL, PAMELA, PHENIX, PHOBOS, PLANCK, QuarkNet, Qweak, RICE, SAMPLE, SELEX, SigN, SNAP, SNO, STAR, TERA, TOTEM, TWIST, VENUS, VIRGO (ref: http://www.hep.net/experiments/all_sites.html) Marek Domaracky
Current and Future Challenges • Connectingconference rooms, offices, auditoria, homes, and mobile clients, thus releasing users from locating special purpose conference rooms • Interconnectingany standard client protocol using any media including audio, video, document sharing, chat, etc. • Operating seamlesslyacross local area (LAN) and wide area (WAN) IPresearch and education networks used by HEP, as well as the public Internet • Allowing integration into physicists’ daily desktop/laptop working environments, such as the Grid-enabled Analysis Environment developed at Caltech and elsewhere Marek Domaracky
Process to Developing Collaborative Tools Industry products Global Science Projects • Usual Method • Lot of Frustrations Integration of some products • Get requirements • (unique for large scale collaborations) • Build a Collaboration System Investment in Support and Developments Marek Domaracky
End-to-End Self Managed RTC Infrastructure Why can we not achieve total reliability/robustness when deploying a RTC Infrastructure ? • The Real-Time Collaborative environment is a living environment: constantly changing, evolving • In addition, devices/domains/nodes are managed by several independent technical and administrative entities. Marek Domaracky
Solution ? Solutions ? • By creating a ”living” RTC Infrastructure capable toreact/adapt to the change of the environment in real-time transparently to the end-user. Marek Domaracky
The Collaboration Network Infrastructure Apart from VRVS (and its successor EVO), existing conferencing and collaboration products and services are inadequate to meet the usability, quality, scalability, reliability, and cost requirements of large globally distributed collaboration The reason is that the network infrastructure componenthas been always the central element of theVRVS/EVO architecture design for collaboration Managing the collaboration service Managing the network Marek Domaracky

Software Agents in the Core Infrastructure:Increase functionality and reduce operational manpower Intelligent Software Agents create an Overlay Network • Functionality (a partial list): • Dynamic registrationto high level directory services to provide a global infrastructure view • Automatic re-activation of components and services • Automatic and securecode update • Continuousmonitoring of network quality (packet loss, jitter, latency) between its peers and its possible peers • Automatic reroutingto obtain the best performance/quality • Encryptionbetween central nodes and between node and clients • Automatic Alarm notifications when monitored parameters • (system or network) go beyond a preset threshold • Dynamically provides services(video, audio, data,..) that matches the currentresources/capabilities to the end users/applications • Access toreal-time and historical monitoring data
Building an End-to-End Self Managed RTC Infrastructure All Communication channels are tunneled via ONE port (UDP or TCP). Crossing Firewall and NAT environment !!
