Abstract: Some examples herein disclose identifying a service function chain based on a switch address from a packet. The examples disclose modifying the switch address to an address corresponding to a service function based on the identified service function chain. The examples also disclose forwarding the packet to the service function according to the modified switch address.

Abstract: In some examples, a network node receives a packet from an adjacent node in a packet-switched network. The receiving node can forward the packet to a destination node via a minimum cost forwarding node adjacent to the network node or to a non-minimum cost forwarding node adjacent to the network node based on routing criteria for the packet-switched network. The routing criteria can include whether the adjacent node that sent the packet to the receiving node is a non-minimum cost node between a source node and the destination node for the packet.

Abstract: According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions. The instructions may cause the processor to intercept a packet from a downstream service function classifier, in which the packet includes metadata that specifies an ordered set of service functions within a service function chain to be implemented on the packet, generate a correlation cookie that associates the packet with the service function chain, and encode the correlation cookie into the packet. The instructions may also cause the processor to store the correlation cookie and the metadata in a cache to correlate the correlation cookie and the metadata and send the packet with the encoded correlation cookie to the service function provider.

Abstract: A system includes spine network switching devices, leaf network switching devices, and server computing devices. The leaf network switching devices are not connected to one another. Each leaf network switching device is connected to each spine network switching device. Each server computing device is connected to each leaf network switching device. Each leaf network switching device transmits an advertisement indicating uplink bandwidth to each spine network device. Each server computing device distributes network traffic through the leaf network switching devices to the spine network switching devices based on the uplink bandwidth that the leaf network switching devices advertise.

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: 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.
