SARLib, an ATM SAR Library

Introduction

This is an Open Source ATM SAR Library. It is published with a GNU License. It has been written to be used under Linux, but there are plans and provisions for a user space version ;).

Features and Specifications

At the moment the SARLib handles the following

• ATM cell generation.
• ATM AAL0 (raw cell) generation
• ATM AAL5 generation
• AAL0 demultiplexing into multiple virtual connections

In other words, SARLib can now be usedas an AAL5 ATM Segmentation And Reassembly engine. At the moment there is no I361 and I363.5 compliance, but this is on the ToDo list.

To Do

• AAL0 I361 compliancy.
• AAL5 I363.5 compliancy
• sk_buf buffer spans. now, only a single sk_buff is supported.
• AAL34 AAl1 and maybe even AAL2 support, in that order. AAL1 might be implemented before AAL34, because of the simplicity. AAL2 might never be implemented because I have no clear idea how to model it. (yet;)
• speed optimalizations!
• more intelligent buffer management.

Buglist

• there is no check on multiple openings of the same VCC
• probably lot's more ;-)

Downloads

I cannot and will not force you, but if you choose to download this library, I would like to know where it will be used. It is just to have an idea of whether and where it is used and if continued development is usefull. A simple mail is all I ask. If you use it in any of the projects listed at the bottom, you are excused ;)

You can download the library here
