10.1.10. More Pipe Examples Chapter 10. Traffic Management • Select the traffic to manage through Pipe Rules. • Pipe Rules send traffic through Pipes. • 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 total limit for the pipe 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. 10.1.10. More Pipe Examples This section looks at some more scenarios and how traffic shaping can be used to solve particular problems. A Basic Scenario The first scenario will examine the configuration shown in the image below, in which incoming and outgoing traffic is to be limited to 1 megabit per second. 460
