    Abstract: In accordance with examples disclosed herein, a filter table for Media Access Control (MAC) chaining contains mappings between signature addresses, service functions, and management functions, to identify corresponding service function chains. The filter table is to store statistic information about the packet. A controller is to uniquely identify a management function corresponding to the signature address, and modify tables of packet signature addresses usable to modify the packet to cause the packet to be forwarded to the management function. The controller is to update the statistic information about the packet.

    Abstract: In an example, a hierarchical chaining gateway (hCG) includes a first communication interface corresponding to a first domain using a first chaining protocol, and a second communication interface corresponding to a second domain using a second and different chaining protocol. The hCG receives a service packet including a first service function chain header via the first communication interface. The hCG also identifies a key identifier in the service packet, and retrieves a second service function chain header based on the key identifier. Then, the hCG transforms the service packet by substituting the first service function chain header corresponding to first domain in the service packet with the second service function chain header corresponding to the second domain. Next, the hCG transmits the service packet including the second service function chain header via the second communication interface corresponding to the second domain.

    Abstract: A method includes receiving a data packet from a source endpoint included within a source endpoint group identified by a source endpoint group policy identifier, where the data packet includes a first multicast address. The method also includes transforming the data packet into a transformed data packet that includes a second multicast address constructed using the source endpoint group policy identifier and a multicast index that specifies a multicast forwarding policy between the source endpoint group and one or more destination endpoint groups identified by one or more destination endpoint group policy identifiers. The method further includes forwarding the transformed data packet toward one or more destination endpoints included within the one or more destination endpoint groups, with the forwarding being based on the second multicast address. The data packet may be routed using a forwarding path based on a multicast forwarding tree constructed for the second multicast address.

    Abstract: Examples include receiving a rule for communication between a first group and a second group of endpoints in a network. The network may include a plurality of networking devices. Examples include receiving a first identifier for the first group and a second identifier and a network address for the second group, receiving composition data of the network. Examples also include determining a topology of the network comprising a first number of communication paths and determining a reduced topology based on the rule, the first identifier, and the second identifier. The first number of paths may link a first networking device out of the plurality of networking devices to each device of the plurality of the networking devices. The second number of paths may link the first networking device to the second group.
