Ingress and Egress Traffic Shaping

The terms Ingress source and Egress source are with respect to the VDS.

For example:

Ingress – When you want to monitor the traffic that is going out of a virtual machine towards the VDS, it is called Ingress Source traffic. The traffic seeks ingress to the VDS and hence the source is called Ingress.

Egress – When you want to monitor the traffic that is going out of the VDS towards the VM, it is called egress

Traffic Shaping concepts:

Average Bandwidth: Kbits/sec

Target traffic rate cap that the switch tries to enforce. Every time a client uses less than the defined Average Bandwidth, credit builds up.

Peak Bandwidth: Kbits/sec

Extra bandwidth available, above the Average Bandwidth, for a short burst. The availability of the burst depends on credit accumulated so far.

Burst Size: Kbytes

Amount of traffic that can be transmitted or received at Peak speed (Combining Peak Bandwidth and Burst Size you can calculate the maximum allowed time for the burst

Traffic Shaping on VSS and VDS

VSS

Traffic Shaping can be applied to a vNetwork Standard Switch port group or the entire vSwitch for outbound traffic only

VDS

Traffic Shaping can be applied to a vNetwork Distributed Switch dvPort or the entire dvPort Group for inbound and outbound traffic

    Hi there!,

    Can you help in providing few examples of uses of above traffic shaping and also examples of bidirectional traffic shaping.
