Depending on various parameters, such as the host and virtual switch used, you can observe a difference in the network rate in your cloud. For example, on a VMware host the actual network rate varies based on where they are configured (compute offering, network offering, or both); the network type (shared or isolated); and traffic direction (ingress or egress)." msgstr "" #. Tag: para #, no-c-format msgid "The network rate set for a network offering used by a particular network in &PRODUCT; is used for the traffic shaping policy of a port group, for example: port group A, for that network: a particular subnet or VLAN on the actual network. The virtual routers for that network connects to the port group A, and by default instances in that network connects to this port group. However, if an instance is deployed with a compute offering with the network rate set, and if this rate is used for the traffic shaping policy of another port group for the network, for example port group B, then instances using this compute offering are connected to the port group B, instead of connecting to port group A." msgstr "" #. Tag: para #, no-c-format msgid "The traffic shaping policy on standard port groups in VMware only applies to the egress traffic, and the net effect depends on the type of network used in &PRODUCT;. In shared networks, ingress traffic is unlimited for &PRODUCT;, and egress traffic is limited to the rate that applies to the port group used by the instance if any. If the compute offering has a network rate configured, this rate applies to the egress traffic, otherwise the network rate set for the network offering applies. For isolated networks, the network rate set for the network offering, if any, effectively applies to the ingress traffic. This is mainly because the network rate set for the network offering applies to the egress traffic from the virtual router to the instance. The egress traffic is limited by the rate that applies to the port group used by the instance if any, similar to shared networks." msgstr "" #.
