Recommendations
The ACX7100-32C/48L and ACX7509 are excellent choices for access and aggregation purposes. They offer enhanced performance and a wide range of advanced features, delivering significant scale and performance over previous generation ACX platforms. Both the ACX7100 and ACX7509 are particularly well-suited for the HSR or Lean Edge metro segments, as they provide the necessary scale, bandwidth, and performance characteristics. The ACX7100 feature-rich capabilities surpass most access nodes requirements but are ideal for supporting 400G Fronthaul or Metro Access deployments.
EVPN-VPWS is primarily tested at scale, but Flexible Cross Connect (FXC) may further improve HSR resiliency by aggregating services and reducing control plane scale. However, no issues were seen on ACX7000 series handling these services at scale with E-OAM for single-homed EVPN.
Segment routing is a recommended underlay architecture to support end-to-end Seamless MPLS stitching with BGP-LU across multiple IGP and inter-AS domains; this can be further enhanced with seamless segment routing and BGP-CT once supported, starting with Junos OS 23.1R1-EVO. By utilizing TI-LFA and ECMP mechanisms, we can achieve fast failover and resilience in the reference architecture. The ACX7100 and ACX7509 platforms can be confidentially deployed to support the featured protocols and services.
While the reference design of this JVD is the 5G xHaul infrastructure, the technologies and practical solutions covered can be leveraged as building blocks from which additional designs may evolve to support multidimensional network architectures.
