INTERCONNECTING ISOLATED NETWORKS WITH OVERLAPPING ADDRESS RANGES VIA SCALABLE VIRTUAL TRAFFIC HUBS

摘要

Configuration operations to enable connectivity, using a virtual traffic hub, between a plurality of isolated networks including a first isolated network with a first private address range, are initiated. The hub includes a plurality of nodes including a decision master node responsible for determining routing actions for packets received at the hub. At the decision master node, a translation mapping is obtained for a second private address range of a second isolated network, which overlaps with the first private address range. At a particular node of the hub, using the mapping, a header of a network packet received from the second isolated network and directed to a destination outside the second isolated network is modified.
