- * The ATM queuing discipline provides a framework for invoking classifiers
- * (aka "filters"), which in turn select classes of this queuing discipline.
- * Each class maps the flow(s) it is handling to a given VC. Multiple classes
- * may share the same VC.
- *
- * When creating a class, VCs are specified by passing the number of the open
- * socket descriptor by which the calling process references the VC. The kernel
- * keeps the VC open at least until all classes using it are removed.
- *
- * In this file, most functions are named atm_tc_* to avoid confusion with all
- * the atm_* in net/atm. This naming convention differs from what's used in the
- * rest of net/sched.
- *
- * Known bugs:
- * - sometimes messes up the IP stack
- * - any manipulations besides the few operations described in the README, are
- * untested and likely to crash the system
- * - should lock the flow while there is data in the queue (?)

- -----------------------------------------------------------------------
-
- Algorithm skeleton was taken from NS simulator cbq.cc.
- If someone wants to check this code against the LBL version,
- he should take into account that ONLY the skeleton was borrowed,
- the implementation is different. Particularly:
-
- --- The WRR algorithm is different. Our version looks more
- reasonable (I hope) and works when quanta are allowed to be
- less than MTU, which is always the case when real time classes
- have small rates. Note, that the statement of [3] is
- incomplete, delay may actually be estimated even if class
- per-round allotment is less than MTU. Namely, if per-round
- allotment is W*r_i, and r_1+...+r_k = r < 1
-
- delay_i <= ([MTU/(W*r_i)]*W*r + W*r + k*MTU)/B
-
- In the worst case we have IntServ estimate with D = W*r+k*MTU
- and C = MTU*r. The proof (if correct at all) is trivial.
-
-
- --- It seems that cbq-2.0 is not very accurate. At least, I cannot
- interpret some places, which look like wrong translations
- from NS. Anyone is advised to find these differences
- and explain to me, why I am wrong 8).
-
- --- Linux has no EOI event, so that we cannot estimate true class
- idle time. Workaround is to consider the next dequeue event
- as sign that previous packet is finished. This is wrong because of
- internal device queueing, but on a permanently loaded link it is true.
- Moreover, combined with clock integrator, this scheme looks
- very close to an ideal solution. */
