Source Packet Routing in Networking (SPRING) or Segment Routing

  • Compute traffic-engineered path delays using delay metrics (ACX5448, MX480, MX960, MX2010, MX2020, and PTX10008)—Starting in Junos OS Release 21.4R1, you can use delay-based metrics for a Path Computation Element (PCE) to compute traffic engineered paths. You can use delay-based metrics to steer packets on the least latency paths, or the least delay path. To do this, you need to measure the delay on every link and advertise that using a suitable routing protocol (IGP or BGP-LS), so that the ingress has the per link delay properties in its TED.

  • Support for SRv6 LSPs in PCEP (MX Series)—Support for SRv6 LSP in PCEP (MX Series)- Starting Junos OS Release 21.4R1, all types of SRv6 LSPs, such as PCE-Initiated, locally created, and delegated SRv6 LSPs are supported in the Path Computation Element Protocol (PCEP).
