Serving capacity
The maximum serving capacity of each GGC node, in Gbps, is shown in the ISP Portal assets view. The value is a hard limit on the traffic which can be sent from the node. It depends on the hardware used and the number of machines in the node.
Egress target
The egress target is a logical limit on the traffic sent from a GGC node to users, in Gbps. It should normally be set to the same value as the Serving Capacity (maximum egress). If you have a capacity limit or bottleneck between the GGC node and users, you may want to temporarily set the egress target to a value lower than maximum.
