Torro is a clean java UDP/TCP app to share files between hosts. Requirements for project here;
Project meets all requirements in above website.
- host2host (TCP or UDP mode)
- multihost (TCP or UDP mode)
You can also:
- Request file list from remote host
- Push file to remote host
- Pull file from remote host
- Resume file downloading
- Download one file from many hosts at once
mvn clean package
java -jar torro-<version>.jar <debug mode true/false> true <port> <folder path> <other hosts ports delimeted by space>
For example
java -jar torro-<version>.jar false true 10001 TORrent_1 10002 10003
java -jar torro-<version>.jar <debug mode true/false> false <port> <folder path> <other hosts ports delimeted by space>
For example
java -jar torro-<version>.jar false false 10001 TORrent_1 10002 10003

Torro use a wide variety of packets.
- FileListPacket
- LogOnPacket
- PullFilePacket
- PullFilePartsPacket
- PushFilePacket
- PushFilePartsPacket
- RequestFileListPacket
All packets extends base Packet which contains byte array where most data is written during Serialization.
If packet size is too huge then packet will be chunked into smaller packets. Host which receive chunks will wait until he receives all chunks and then will collect them into one packet and proceed with operations.
- Request file list from remote host
(Host(H1) sends RequestFileListPacket to remote host(H2). When H2 receives packet then he sends FileListPacket to H1. H1 loads packet and reads file list.
- Push file to remote host
Host(H1) pack file into PushFilePacket and send it to remote host(H2). When H2 receives packet then he load packet and read file from it.
- Pull file from remote host
Host(H1) pack file description into PullFilePacket and send it to remote host(H2). When H2 receives packet then he look for requested file. If found then he build PushFilePacket and send it to H1. When H1 receives packet then he load packet and read file from it.
- Resume file downloading
Host(H1) send PullFilePartsPacket to all host connected with him. Packet contains file description and requested file parts. Other hosts(O1) looks for file in their folders and if found then they build PushFilePartsPacket and send it to H1. When H1 receives packet then he load packet and join new data with existing one and read file from it.
- Download one file from many hosts at once
Host(H1) send PullFilePacket with file description to all hosts connected with him (O1). Other hosts(O1) looks for file in their folders and if found then they build PushFilePacket and send it to H1. When H1 receives packet then he load packet and read file from it.
Base packet which is Serializable. Contains methods to pack packet into byte array or load packet from byte array.
private final long id; //Unique file id
private final int part; //File part
private final int maxPart; //Max file part (if packet is not chunked then its 1)
private Byte[] data; //Some data
Packet contains list of host(H1) files. Host(H2) which receives this packet will now know what files are on other host(H1).
List with files is written to byte array.
Packet is sent in TCP mode only on first connection. It's just a ping packet.
Packet contains file description of file we want to get from remote host(H1). Remote host(H1) will receive this packet and if he has the file then will build PushFilePacket containing file data.
The same like PullFilePacket but with specified chunk numbers we want to pull.
List<Integer> pargs; //Chunk parts
Packet contains file content. It is sent from host(H1) to remote host(H2). When remote host(H2) receive this packet then he will get byte array and deserialize it into file.
The same like PushFilePacket but with specified chunk numbers we want to push.
List<Integer> pargs; //Chunk parts
Packet which ticks remote host(H1) to send us(H2) his list of files.
MIT but it's not recommended to use any significant part of code from there in your own one (at least at PJATK) to not trigger plagiarism (I don't care how you use it but some poeple care ;) )
