Abstract
Methods for segment routing in a software-defined networking (SDN) system are disclosed. In one embodiment, a method includes receiving a plurality of values of maximum segment identifier (SID) depths, each from one network element of the SDN system, and identifying a path for a packet to transmit through a plurality of network elements, where a plurality of SIDs corresponding to the plurality of network elements is ordered to represent the path. The method further includes splitting the path into a plurality of sub-paths based on the values of the maximum SID depths of the plurality of network elements, where each network element, for the path, is allocated to process a number of ordered SIDs, and where the number is within the network element's maximum SID depth, and causing packet forwarding of the packet along the plurality of sub-paths based on SIDs allocated to the network elements.
