Abstract
A service function chain (SFC) merging method implemented by a service function (SF) node. The SFC merging method includes receiving a plurality of diverted SFC packets; determining a set of matching diverted SFC packets from the plurality of diverted SFC packets; merging the set of matching diverted SFC packets into a merged SFC packet; and transmitting the merged SFC packet.
Claims20
A service function chain (SFC) diversion method implemented by a service function (SF) node, the SFC diversion method comprising:
- receiving an SFC packet;
- determining, based on packet data, that the SFC packet is to be rerouted from a first Service Function Forwarder (SFF) of the SFC to a second SFF of the SFC;
- modifying a service index (SI) in a network service header (NSH) of the SFC packet to reroute the SFC packet to the second SFF;
- and
- transmitting the SFC packet.
A service function chain (SFC) multi-path diversion method implemented by a service function (SF) node, the SFC multi-path diversion method comprising:
- receiving a SFC packet;
- determining, based on packet data, that the SFC packet is to be diverted to multiple Service Function Paths (SFPs) of the SFC;
- generating a copy of the SFC packet for each of the multiple SFPs to produce a plurality of diverted SFC packets;
- modifying the plurality of diverted SFC packets to include merging information for merging the plurality of diverted SFC packets;
- and
- transmitting the plurality of diverted SFC packets.
A service function chain (SFC) merging method implemented by a service function (SF) node, the SFC merging method comprising:
- receiving a plurality of diverted SFC packets;
- determining a set of matching diverted SFC packets from the plurality of diverted SFC packets;
- merging the set of matching diverted SFC packets into a merged SFC packet;
- and
- transmitting the merged SFC packet.
