Streaming support of NET Remoting

Overview of Java RMI Advantage: Support seamless remote invocation on objects in different computer l Disadvantage: Each Call must go through the Internet l

Compare Java RMI and NET Remoting l NET Remoting have more flexibility than RMI l In server side, they have different behavior ¡ NET: Each remoteobj open port to listen client request ¡ RMI: Each remoteobj must register in order to let client can loop up to find it.

Streaming Support of Java RMI Let Java RMI have Streaming ability l Reduce time of Network communication l

How to modify Java RMI l Streaming ¡ Let its hide in the stub l Modify ¡ Controller &Streaming Buffer the registry Let client look up registry can get more than one source

Example { Stream. Data obj call must go =Naming. lookup(id); Each through internet whlie(true){ num=obj. read(data, 512); if(num==0)break; process(data); } } { Stream. Data obj =Naming. lookup(id); Before go through internet, check the whlie(true){ local buffer obj. Initialize(…); num=obj. read(data, 512); if(num==0)break; process( data); } }
