How each is put together

Same four layers. Different suppliers.

Both are commercial and carrier-grade, both run the same standards, and both come with SLAs and a global support organization. A router is four layers either way. What differs is who supplies each layer, and whether you can change one of them without changing the rest.

How to choose

Which one fits your network

The protocol sets overlap heavily, so the decision usually comes down to how you want to buy and operate the network.

Choose IP Infusion when you want
  • Licensing you own. Perpetual and term options, licensed separately from the hardware, so the features you depend on stay a cost you own rather than one you renegotiate at every renewal.
  • Hardware you can compete. The same OcNOS image runs on merchant-silicon platforms from Edgecore, UfiSpace and Celestica, so the box can go out to bid without changing the network OS.
  • Layers that stay separable. Hardware, software and optics are bought on their own merits, so a change of supplier in one does not force a change in the others.
  • Multi-vendor optics. Pluggables with proven interoperability from several suppliers, including 400G ZR and ZR+ coherent for IPoDWDM and DCI.
  • Support from one team. One responsive IP Infusion team backs both the software and the hardware, under a single contract and one RMA path, so a problem does not bounce between suppliers.
Choose Juniper when you want
  • A single vendor across hardware, software and support, with one JTAC relationship.
  • Operations already standardized on Junos OS or Junos OS Evolved, with Juniper tooling, automation and processes you intend to keep.
  • Features that live in the Junos stack specifically, such as advanced BNG and subscriber management on MX, or Junos-proprietary behavior your design depends on.
Platform mapping

Five Juniper anchor platforms, mapped by capacity and role.

Each row pairs a Juniper anchor platform with its IP Infusion equivalent, the one-way capacity comparison, the fit verdict and the key caveat. Where one IP Infusion platform does not carry the capacity, the row says so and names the combination that does.

Juniper platform IP Infusion equivalent Ports Capacity Match Notes
Juniper MX204SP edge / aggregation / DCI · Junos Trio AGR130 / S9510-28DCOcNOS-SP 8×10G + 4×100G → 48×10G + 6×100G 400G → 800G Capacity headroom Confirm in the assessment: Trio BNG subscriber scale and DCI throughput against your port mix.

Role, ports and capacity all line up Same capacity class Design review

How to read these. Rows are matched on role, port profile and capacity, and capacity is stated one way on both sides. Silicon is named only where the vendor names it: Juniper publishes the Trio chipset for the MX204 and Express4 for the PTX10001-36MR, and publishes no forwarding ASIC for the QFX5120, QFX5220 or ACX7100, so no Broadcom part is attributed to those platforms here. Specific feature areas (BNG scale, MACsec line-rate density, Class C timing, RSVP-TE facility-backup form) depend on your deployment and are confirmed by the migration assessment. No anchor SKU is presented as a guaranteed one-to-one swap. OcNOS competes strongest in standards-based routing, EVPN fabrics, metro aggregation and IP/optical transport; advanced BNG and subscriber-management workloads warrant deeper architecture work.

Vendor context

HPE closed the Juniper acquisition on 2 July 2025.

HPE completed its acquisition of Juniper Networks on 2 July 2025 at an announced equity value of approximately 14 billion US dollars. A US DOJ consent decree required HPE to divest the Instant On wireless LAN business and license Juniper Mist AIOps source code to third parties. The combined networking organization is branded HPE Networking, with HPE Juniper Networking and HPE Aruba Networking retained as sub-brands, and MX, PTX and QFX platforms continue to ship. That is the published record, and it is linked below. We make no claims about future roadmap or support windows.  HPE acquisition release.

Customer reference

Operators who made the move, and why.

Operators who have moved production traffic off Juniper, and in some cases Cisco, onto OcNOS on open hardware. Each reason below is the one the operator gave in its own published story.

BroadStar Replaced Juniper switches for MDU residential access. Cited OcNOS interoperating with other vendors, so hardware could be matched to budget and feature requirements, and a return on investment in months rather than years. Read the story → Celerity Internet / WispWest Moved off MikroTik and Juniper, which could not meet the scalability the company needed. Cited greater scalability from edge to core, better BGP router scalability, and compact, energy-efficient MPLS routing for tower sites with limited space. Read the story → Haefele Connect A former Cisco and Juniper network, now OcNOS-SP on Edgecore for L3 aggregation. Cited high-density 10G with medium-density 100G ports, equipment available in weeks instead of years, and interoperation with the Juniper system already deployed. Read the story → Vyve Broadband On track to 200 OcNOS nodes, displacing Cisco and Juniper. Cited the flexibility to convert existing hardware to OcNOS while gaining service-provider feature sets, and quicker deployment cycles on one standardized platform. Read the story →
FAQ

Frequently asked questions

Does IP Infusion sell complete switches and routers, or just the OcNOS software?
Both. The main offering is the finished product: a carrier-grade router or switch with OcNOS pre-installed on open hardware, plus the optics and the support contract, delivered as one system and validated on the Hardware Compatibility List. If you already run open hardware, you can license OcNOS on its own for it. Because hardware, software and optics stay separable, you can change any one of them later without replacing the others.
Can OcNOS replace a Juniper MX204 1:1 for SP edge and aggregation?
At the protocol layer yes: OcNOS-SP carries BGP, IS-IS, OSPF, MPLS-LDP, SR-MPLS, EVPN-MPLS, RSVP-TE, L2VPN/L3VPN, QoS, and IEEE 1588v2 timing on Edgecore AGR-series and UfiSpace SP platforms. The MX204 port profile (4xQSFP28 + 8xSFP+, 1RU, 400 Gbps) is closest to Edgecore AGR130 (AS5916-54XKS) for low-density edge work, and to UfiSpace S9510-28DC for higher-density aggregation. Trio-specific BNG subscriber scale and DCI throughput do not have a published OcNOS comparison, so a 1:1 swap for those workloads needs an SE design review against your actual port mix and feature usage.
What is the OcNOS equivalent for a QFX5120-48Y DC leaf?
Edgecore AS7326-56X (DCS203) is the port-for-port match: 48x25G SFP28 with 8x100G QSFP28 uplinks at 2.0 Tbps, the same profile Juniper publishes for the QFX5120-48Y (up to 2 Tbps unidirectional). UfiSpace S8901-54XC is the same class with 6x100G uplinks rather than 8. Both run OcNOS-DC with EVPN-VXLAN, BGP-EVPN and MAC-VRF, so the overlay primitives carry across. Juniper does not publish the forwarding ASIC for the QFX5120, so the match is made on role, ports and capacity. The SKU choice depends on copper-versus-fiber port preference and uplink mix, which the migration assessment maps against the HCL.
Does OcNOS run on a 32x400G spine equivalent to the QFX5220-32CD?
Yes. OcNOS-DC ships on the Edgecore AS9716-32D (Broadcom Tomahawk-3, 32x400G QSFP56-DD, 12.8 Tbps) for EVPN-VXLAN spine duty, which matches the QFX5220-32CD port for port and at the same 12.8 Tbps Juniper publishes. Juniper does not publish the forwarding ASIC for the QFX5220. For AI fabric workloads we steer customers to Broadcom Tomahawk 4 and Tomahawk 5 platforms instead, so the QFX5220 is not the AI-fabric platform on either side.
How close is OcNOS-SP feature parity with the ACX7100 for 5G xHaul and SR-MPLS aggregation?
Juniper publishes the ACX7100 at 4.8 Tbps (32C = 32x100G + 4x400G; 48L = 48x10/25/50G + 6x400G) and does not publish its forwarding ASIC. On capacity the match is UfiSpace S9600-56DX at 4.8 Tbps (8x400G + 48x100G, Broadcom Qumran2c), with Edgecore AS9947-36XKB (AGR560) as the headroom option at 7.2 Tbps on Jericho2C+. For smaller cell-site and access-gateway roles the Qumran-class AGR400, AGR130 and CSR440 platforms cover the tier below. Public validation includes the SKT 400G OpenZR+ live PoC (Jun 2025), the AnschlussWerk Edgecore and OcNOS wireline deployment (Nov 2024), and the TIP Validated Solution Gold Badge for the OcNOS DCSG profile. MACsec port density at line rate and Class C timing (T-BC, SyncE, PTP, 1PPS and 10 MHz GPS in and out) are the two feature areas to confirm against your specific deployment.
Is there an OcNOS-SP equivalent for the PTX10001-36MR compact core?
Yes, but it has to be sized honestly. Juniper publishes the PTX10001-36MR at 9.6 Tbps (24x400G + 12x100G, 1RU) on Express4 silicon, which is a large box. The single-platform answer is OcNOS-SP on the UfiSpace S9610-36D: 36x400G at 14.4 Tbps on Broadcom Jericho2c+ with a 16 GB buffer, in 2RU. The Edgecore answer is two AS9947-36XKB (AGR560) units at 7.2 Tbps each, also Jericho2c+; one on its own does not reach 9.6 Tbps. Express4 and Jericho2c+ are architecturally distinct, so buffer depth, FIB/RIB and LSP scale and MACsec line-rate density are compared against your peering and core requirements. This is the most design-dependent of the five anchor mappings and is handled as a per-deployment design exercise rather than a SKU-for-SKU swap.
How does Junos route-policy translate to OcNOS route-map syntax?
Junos policy-statement is a chained match-and-then language attachable from any protocol; OcNOS route-map is the industry-standard sequence + match/set form, which covers most real BGP and IGP redistribution patterns but is structurally narrower. Migration projects need a policy-translation pass rather than a line-by-line port. The CLI cheat-sheet below shows the standard mappings; complex nested Junos policy chains should be validated before cutover.
Does OcNOS support sub-50 ms FRR with RSVP-TE the way Junos does?
OcNOS-SP MPLS documents RSVP-TE FRR one-to-one with node-protection and the corresponding configuration form. BFD provides the fast failure detection that, combined with pre-computed FRR backup paths, supports sub-50 ms protection; achievable times depend on the BFD interval/multiplier, hardware offload, and platform (OcNOS BFD minimum 3 ms hardware, 10 ms software). Facility-backup (link-protection / bypass) and auto-bandwidth are documented in the broader OcNOS-SP MPLS tree. For the specific FRR coverage you need - detour vs facility, link vs node protection, and CSPF constraints - contact us for the detailed mapping.
What did the HPE acquisition of Juniper change?
HPE closed its acquisition of Juniper Networks on 2 July 2025 at an announced equity value of approximately 14 billion US dollars. A US DOJ consent decree required HPE to divest the Instant On wireless LAN business and to license Juniper Mist AIOps source code on a perpetual, non-exclusive basis to third parties. The combined networking organization is branded HPE Networking, with HPE Juniper Networking and HPE Aruba Networking retained as sub-brands, and MX, PTX and QFX platforms continue to ship. Those are the published facts, and they are linked on this page. We do not speculate about future roadmap or support windows.
How does OcNOS licensing compare to Juniper on cost and lock-in?
OcNOS licenses the software independently of the hardware, with perpetual and term options and progressive feature tiers unlocked by software upgrade, so the software cost is visible and separable from the box, and the hardware can be competed across ODMs on the Hardware Compatibility List. Router licensing across the industry is broadly shifting toward subscription and term models, so a renewal or a refresh is a good moment to model the full multi-year cost. Vendor-neutral questions worth asking any incumbent: which capabilities are perpetual versus subscription, whether any feature previously included now carries an annual fee, and how purchase price, support price, and lead time compare for the same role. Per-deployment cost figures come from an IP Infusion migration assessment rather than a marketing chart.

Where IP Infusion fits

A finished router or switch, sourced on open terms.

Juniper is a mature incumbent with a deep portfolio and JTAC behind it. IP Infusion competes on procurement: merchant-silicon hardware you can compete across ODMs, software licensed separately from the box and available perpetually, and optics from more than one supplier, delivered as a finished router or switch validated on the Hardware Compatibility List. Where your requirement is the standards-based protocol set, that is the trade worth pricing.
