Network

The Network project is an encrypted, high-performance, event-driven/reactive Network stack with DNS and RMI, using Netty, Kryo, KryoNet RMI, and LZ4 via TCP/UDP/UDT.

These are the main features:

• The connection between endpoints is AES256-GCM / EC curve25519.

• The connection data is LZ4 compressed and byte-packed for small payload sizes.

• The connection supports:

• Remote Method Invocation

  • Blocking
  • Non-Blocking
  • Void returns
  • Exceptions can be returned

• Sending data when Idle

• "Pinging" the remote end (for measuring round-trip time)

• The available transports are TCP, UDP, and UDT

• There are simple wrapper classes for:

  • Server
  • Client
  • DNS Client (for querying DNS servers)
  • MultiCast Broadcast client and server discovery

• Note: There is a maximum packet size for UDP, 508 bytes to make sure it's unfragmented

• This is for cross-platform use, specifically - linux 32/64, mac 32/64, and windows 32/64. Java 6+

(We now release to maven!

There is a hard dependency in the POM file for the utilities library, which is an extremely small subset of a much larger library; including only what is necessary for this particular project to function.

This project is kept in sync with the utilities library, so "jar hell" is not an issue. Please note that the util library (in it's entirety) is not added since there are many dependencies that are not necessary for this project. No reason to require a massive amount of dependencies for one or two classes/methods.
