Argon Networks

Argon Networks was a late-1990s networking infrastructure startup that developed a high-speed routing switch for what was then described as the next-generation multi-service Internet, combining IP routing with ATM switching in a single carrier-class platform. The company was venture backed by Canaan Partners (Series B, partner Eric Young), Matrix Partners, New Enterprise Associates and Greylock. Siemens acquired Argon Networks in March 1999 in a deal reported at roughly $240 million and folded the team into Unisphere Solutions / Unisphere Networks, the carrier-infrastructure unit later acquired by Juniper Networks in 2002. Argon Networks predates the public web API era: it shipped carrier networking hardware, never operated a developer program, and has no surviving website, documentation, SDKs or API surface. This profile is retained as a historical venture-portfolio record rather than as an active API provider.

Argon Networks is profiled on the APIs.io network. Tagged areas include Company, Networking, Internet Infrastructure, Routing, and Switching.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
