§Prey
Packet Routing Engine Yield
This is the core of the whole framework By now, contains buffer management and recycling.
Its still under development
§Buffer Management
The way PREY deals with buffers is simple but smart: It allocates space once, and all the remaining management is done by itself. This makes PREY really efficient in terms of speed while dealing with memory, since it does not need to depend on kernel and OS services during its runtime, only at its start.
It uses an efficient memory layout to prevent unnecessary space allocation, using cache lines fixed on 64 bits per line.
Buffers have a fixed size of 2048 bytes, and PREY uses the headroom strategy to allow further headers adding without the need of creating another buffer. That way, the network packets fit in the buffer and proxies and firewalls can easily add headers in the response.
