Abstract
The present technology is directed to a system and method for implementing network resource partitioning and Quality of Service (QoS) separation through network slicing. Embodiments of the present invention describe scalable network slicing method based on defining Segment Routing Flexible Algorithm to represent a network slice and assigning a distinct QoS policy queue to each of the Flexible Algorithms configured on a network node. Therefore, scalable network slice based queuing is implemented wherein a single packet processing queue is assigned to each Flex-Algorithm based network slice. QoS policy queue may be implemented in a hierarchical fashion by differentiation between flow packets in a single QoS policy queue based on value of experimental bits in the header.
