| Clusters are a kind of a legacy of the Stingray SG pf_ring-version: in pf_ring, cluster is the basic concept of "one dispatcher thread + RSS handler threads" and is almost the only way to scale. The disadvantage of the cluster approach is that the clusters are physically isolated from each other: it is impossible to forward a packet from the X-interface of cluster #1 to the Y-interface of cluster #2. This can be a significant obstacle in the SKAT L2 BRAS mode. | Clusters are a kind of a legacy of the Stingray SG pf_ring-version: in pf_ring, cluster is the basic concept of "one dispatcher thread + RSS handler threads" and is almost the only way to scale.

| In DPDK, clusters are also isolated from each other, but unlike pf_ring, here a cluster is a more logical concept inherited from pf_ring. DPDK is much more flexible than pf_ring and allows you to build complex multi-bridge configurations with many dispatchers without using clusters. In fact, the only "pro" argument for clustering in the Stingray-DPDK version is the case when you have two independent networks A and B connected to the Stingray SG, which should not interact with each other in any way. | In DPDK, clusters are also isolated from each other, but unlike pf_ring, here a cluster is a more logical concept inherited from pf_ring.
