10.1.11. A Summary of Traffic Shaping
• A pipe can have a limit which is the maximum amount of traffic allowed.
• A pipe can only know when it is full if a limit is specified.
• A single pipe should handle traffic in only one direction (although 2 way pipes are allowed).
• Pipes can be chained so that one pipe's traffic feeds into another pipe.
• Specific traffic types can be given a priority in a pipe
• Priorities can be given a maximum limit which is also a guarantee. Traffic that exceeds this will
be sent at the minimum precedence which is also called the Best Effort precedence.
• At the Best Effort precedence all packets are treated on a "first come, first forwarded" basis.
• Within a pipe, traffic can also be separated on a Group basis. For example, by source IP address.
Each user in a group (for example, each source IP address) can be given a maximum limit and
precedences within a group can be given a limit/guarantee.
• A pipe limit need not be specified if group members have a maximum limit.
• Dynamic Balancing can be used to specify that all users in a group get a fair and equal amount
of bandwidth.
