Hi!
I am learning tcng without having experiance of tc and I am trying to
build something that shall schedule traffic dependent on the value in the
IPv4 packets ip_ttl field.
I have read the tcng reference manual and cannot find information about
forwarding. Is it possible to farward packets from ingress to egress
without sending them upwards in layers?
NIC---->ingress---->forward----->egress---->
In ingress I do some metering and in egress: classifying and Queuing.
Example (basic part of the source):
#includes
#defines
dev eth1 {
$P = bucket(rate 1Mbps, burst 2kB, mpu 64B);
ingress {
class (<>)
if ((ip_ttl & 0x81) == 0x81) &&
(conform $p && count $P);
drop if 1;
}
egress {
class (<$high>) if (((ip_ttl & 0x1E) >> 1) <= 0x0F) &&
(((ip_ttl & 0x1E) >> 1) >= 0x0C);
class (<$mid>)....
class (<$low>)....
prio {
$high = class {fifo (limit 64kB);}
$mid = ...
$low = ...
}
}
}
If forwarding is not possible can I use hash table with tcindex to store
information at ingress, and use this information at egress?
Thanks!
/Johan. C
