Welcome to the Zefina Project

The Zefina Project is an implementation of the Bundle Protocol specification for Delay/Disruptive Tolerant Networks.

What is a Delay/Disruptive Tolerant Network?

A Delay/Disruptive Tolerant Network, DTN, is a network were a connection between two endpoints may have random disconnects (at best) or never have a direct path (at worst). In these types of conditions, IPv4 and IPv6 will never work because they require a connection between two endpoints to be stable.

Motivation

The primary goal of this BP implementation is a focus on maintainability:

• Code must be easy to modify
• Code must be easy to understand
• Code must be easy to port to other platforms (OS, CPU)
• Code must be well documented
• Data must be easy to understand
• Data must be updatable during runtime (this feature can be disabled)
• Executable must be updatable during runtime (this feature can be disabled)

Other goals include:

• Small executable size (Less than 64M)
  • MUSL integration may adjust this goal
• Speed
  • Faster than the ION-DTN defacto standard
  • Extended CPU Instruction Sets will be optional
