TRAFFIC SHAPING

• Design to slow the output breakdown from output queue to tx-ring
• Goal
• Smooth out or normalize traffic weight when we are sending packets out the interface
• Delay & queue the packets when exceeding traffic
• Shaping will require only when
• Physical serialization rate of link which is based on the physical clocking of interfaces hardware.
• Where serialization rate of out bound is not matching with policed inbound
• Generally based on policed inbound traffic will be shaped at outbound
• Exceed traffic at outbound will be delayed in shaping queue.
• IOS traffic shaping
• Delays the exceeding traffic ony
• Sometimes If queue is large traffic will be dropped when exceeding the rate
