In networking communication,there are 3 main factors which have tobe considered,as mentioned in[Crockett 1997]:latency, bandwidth andcontention.Latency is the time required to set up a communicationoperation,irrespective of the amount of data to be transmitted.Bandwidth is theamount of data which can be transmitted over a channel per unit time.Contentionoccurs when multiple processors are trying to route data through the samesegment of the network at the same time and there is insufficient bandwidth tosupport the aggregate demand.

Fig 1. Framework of the Gridrendering system

When building the Grid rendering framework,the main emphasis is tofocus on the friendly usability,security and stability of the framework.Ourframework is customized to provide a , friendly,secure,and optimizedGrid-based rendering environment for animators to submit and handle theirrendering tasks either via a portal or a GUI plug-in in the modelling tool.

For submission of jobs to the Grid rendering system a portal is proposed(Figure 2).This portal is also an entrypoint for accessing the web services,meta-scheduler,Data Service(DS) andExecution Service Container(ESC)as shown inFigure 3.We compress the original scene representation files beforeuploading them to the rendering servers via the portal.

In the portal implementation,all computers in the Grid were installedwith Globus Toolkit[Globus],[Foster and Kesselman 1998].Globus also providesGlobus Security Infrastructure(GSI) core service and manages accesses andauthorization using a public key infrastructure based on X.509.v3 and SecureSocket Layer(SSL)Protocol/Transport Layer Security(TLS)protocols forauthentications.
