There are 3 parts to the code:
- Chunk Server
- Storage Server
- Client
Codde is available at https://github.ncsu.edu/gpollep/Perfuse.git
Chunk Server is written in Java. Client and Storage Server are written using Python.
The Client uses Python FUSE library from https://github.com/terencehonles/fusepy
To run Chunk Server, please ensure that Java 1.8, MySQL and Maven are installed
To run Client and Storage server, run "source setup.sh" in their respective directories with root privileges. The script downloads and installs all the required modules like Google's gRPC, Protocol Buffer, DB plugins and compiles .proto files.
Use "make clean" for Storage Server and Client to remove any chunks from the local cache.
Root privileges are mandatory for the Storage Server because PyPing module uses ICMP libraries to create ping packets which cannot be accessed without root access.
Mount point for the Client FUSE file system is /tmp/fuse2 which must be created manually before starting the Client.
Replication Factor and the Client IP must be set in Client/constants.py file
Storage Server IP must be set in StorageServer/constants.py file
To run Client use: python fusefs.py "IP address of chunk server"
To run Storage Server use: python storage_server.py "IP address of chunk server"
Visusalizer used in the demo was forked from PubNub. AJAX, RabbitMQ and Web Workers were added to create asynchronous events on the map during file ransfers. Code is available at: https://github.com/gurudarshan266/webgl-visualization.git
