Thanks, yxn. You have seconds. I'll contact you offline to
get you set up.

Hello OpenSolaris folks,
I would like to open an OpenSolaris project - Packet Event Framework
(PEF), on behalf of the PEF project team.
The Packet Event Framework project is a follow-on to FireEngine, which
will provide a framework for fine-grain modularity of the network stack
based on the execution of a series of event functions as specified by
the IP classifier.
PEF will provide the following benefits:
- Better observability as the framework will support dynamic changes
to an event vector.
- Improved performance due to:
- Smaller code footprint by executing the code needed based on
packet classification only.
- Iterative execution of events which leads to smaller stack
depth.
- Fewer parses of the packet. Packet parsing is done once at
classification time.
- Support for multiple vertical perimeters(squeue_t), so a packet
can traverse from one squeue_t to the next. Currently FireEngine
supports a single IP squeue_t requiring packet processing to use
both STREAMS based queuing and FireEngine IP squeue_t queuing. As
a result, a packet can be processed totally within PEF and does
not require any STREAMS processing.
- CMT(Chip Multi-Threading) based processors will additionally
benefit from the multiple squeue_t support through pipe-lined
processing of a connection. Multiple cores and/or threads of a
core can process different layers of the stack. Also, packet
fanout of packets such that multiple packets can be simultaneously
processed.
Thanks in advance for your support!
- yxn
