Presented herein are techniques performed in a network comprising a plurality of network
nodes each configured to apply one or more service functions to traffic that passes the …

Presented herein are elastic service chain techniques. In one example, a network element
receives data traffic to be processed by a service chain that specifies an ordered sequence …

Techniques are provided to decouple service chain structure from the underlying network
forwarding state and allow for data plane learning of service chain forwarding requirements …

A novel scheme is defined for supporting service graphs to allow specific service functions to
be applied to selected subsets of packet flows. According to one or more embodiments, a …

An example method for service node originated service chains in a network environment is
provided and includes receiving a packet at a service node in a network environment that …

A packet is received at a network device hosting a service function that is part of a service
chain. The packet is sent to the network device from an originating network device. The …

An example method for service node originated service chains in a network environment is
provided and includes receiving a packet at a service node in a network environment that …

Presented herein are techniques useful in a network comprising a plurality of network nodes
each configured to apply one or more service functions to traffic that passes through the …

Techniques are described for detecting failure or degradation of a service enabling
technology function independent from an operational state of a service node hosting the …
