Abstract
Examples include techniques to monitor control plane (CP) network traffic. Examples include monitoring CP traffic between one or more user equipment (UEs) wirelessly coupled to a network and a virtual network function arranged to process user plane (UP) traffic for an application service provided to the one or more UEs to determine whether at least a portion of the UP traffic needs to be routed to a different VNF for UP processing.
Claims23
A network interface card (NIC) comprising:
- circuitry to:
- access a memory arranged to maintain data to indicate expected control plane (CP) traffic over a time period to provide an application service to one or more user equipment (UEs) wirelessly coupled to a communication network;
- monitor CP traffic between the one or more UEs and a first virtual network function (VNF) arranged to process the CP traffic for the application service provided to the one or more UEs through a second VNF arranged to process user plane (UP) traffic for the application service, the UP traffic and the CP traffic routed through the NIC;
- compare, following a monitoring time window over a first time period of the time period, monitored CP traffic to the expected CP traffic for the application service during the first time period;
- and
- cause at least a first portion of the UP traffic to be routed to a third VNF arranged to process UP traffic based on the comparison of the monitored CP traffic to the expected CP traffic.
A method implemented at a network interface card (NIC) comprising:
- monitoring control plane (CP) traffic between one or more user equipment (UEs) wirelessly coupled to a communication network and a first virtual network function (VNF) arranged to process the CP traffic for an application service provided to the one or more UEs through a second VNF arranged to process user plane (UP) traffic for the application service, the UP traffic and the CP traffic routed through the NIC;
- comparing, following a monitoring time window over a first time period of a time period, monitored CP traffic to expected CP traffic for the application service during the first time period;
- and
- causing at least a first portion of the UP traffic to be routed to a third VNF arranged to process UP traffic based on the comparison of the monitored CP traffic to the expected CP traffic.
At least one machine readable medium comprising a plurality of instructions that in response to being executed by a system at a network interface card (NIC) cause the system to:
- monitor control plane (CP) traffic between one or more user equipment (UEs) wirelessly coupled to a communication network and a first virtual network function (VNF) arranged to process the CP traffic for an application service provided to the one or more UEs through a second VNF arranged to process user plane (UP) traffic for the application service, the UP traffic and the CP traffic routed through the NIC;
- compare, following a monitoring time window over a first time period of a time period, monitored CP traffic to expected CP traffic for the application service during the first time period;
- and
- cause at least a first portion of the UP traffic to be routed to a third VNF arranged to process UP traffic based on the comparison of the monitored CP traffic to the expected CP traffic.
