SIB2-I-PTX5K-BB Use Case
High-Density Spine Connectivity for Hyperscale Data Centers with SIB2-I-PTX5K-BB
In a hyperscale data center build-out, network engineers deploy Juniper PTX5000 routers fitted with the SIB2-I-PTX5K-BB base bundle to provision up to 40×100GbE or 8×400GbE front-panel ports. This architecture delivers sub-microsecond latency, linear scale to 10 Tbps per chassis, and simplified cabling, resulting in 25 % higher east-west throughput and a 15 % reduction in total cost of ownership.
5G Mobile Backhaul Aggregation and Reliability in Edge Data Centers
A Tier-1 mobile operator integrates the PTX5000 with SIB2-I-PTX5K-BB in regional edge sites to consolidate 5G gNodeB backhaul over IP/MPLS. Leveraging up to 400 GbE trunk ports and segment routing, the operator achieves a 70 % reduction in aggregation nodes, 99.999 % network availability, and streamlined OPEX through automated provisioning and centralized transport management.
Cloud Service Provider EVPN-VXLAN Multi-Tenant Fabric Automation
A global cloud service provider uses PTX5000 routers equipped with SIB2-I-PTX5K-BB to build an EVPN-VXLAN underlay across distributed PoPs. The solution enables automated tenant segmentation, on-demand Layer 2/3 provisioning, and seamless scale to over one million endpoints, delivering 40 % faster service activation, enhanced network visibility, and strict tenant isolation.
