To achieve such requirements !CHAOS, basically developed in C++, employs distributed object caching for real-time data access (Live Database) and a key-v… text/html 2011-08-10T12:43:50+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.infn.it/strutture/lnf/da/chaos/rpc_protocol?rev=1312980230&do=diff RPC Protocol Whit in Chaos all the part, Control Unit, Metadata Server, UI Toolkit talk each other with an rpc system. Due to the abstract design of chaos the RPC system is plugable, so the syntax and semantic os RPC message can be embedded int RCP serialization. Has been chosen BSON to serialize and deserialize action information. With this choice we have only one roc endpoint, this permit to simply migrate the roc protocol to another. text/html 2011-09-01T17:01:17+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.infn.it/strutture/lnf/da/chaos/sw_standard_definitions?rev=1314896477&do=diff STANDARD SOFTWARE DEFINITIONS The chain to reach the device is a linear composition of CL Host descriptor (CLHD) + CL descriptor (CLD) + CU descriptor (CUD) + Device descriptor (DD) = Device Pipe (DP) Since it ---------- * CL Host descriptor (CLHD) text/html 2011-09-06T18:12:09+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.infn.it/strutture/lnf/da/chaos/uitoolkit?rev=1315332729&do=diff UIToolkit The UIToolkit is the library that abstract !CHAOS infrastructure to the clients application.
