Dear RTGWG, SPRING This draft is a very important draft for operators which utilizes a SDN controller optimization to address complex challenges of ephemeral short lived traffic flows that cause congestion that can be network impacting that are difficult to address with existing mechanisms such as PCEP, Netconf/Yang.
The draft is based on the tactical TE concept of tackling ephemeral flow state in the network and utilizes RPC programming to push the short lived SR TE policy to balance short lived flows across the network to eliminate congestion in the network. This draft describes a controller API based SR Policy push solution to tackle unforeseen congestion issues with ephemeral flow state in the network problem as described in the TTE draft below.
