Architecture Overview

OcNOS is an industry-standard network operating system with advanced networking features to meet the demands of data center, enterprise.

 The OcNOS networking protocol modules conform to leading IEEE, IETF, and other industry-specific standards:

  • Layer 2 switching: VLANs, Spanning Tree

  • Layer 3 routing: OSPFv2, OSPFv3, RIP, BGPv4, IS-IS

  • Carrier Ethernet

  • Data center Ethernet OcNOS provides configuration management through these layers:

  • Command line interface

  • SNMP


The major components of OcNOS are grouped into these categories:

  • The Management Interface that is used to configure and operate the OcNOS routing and switching protocols.

  • Protocol components, which include:

  • Layer 2 Protocols

  • Layer 3 Protocols

  • Multicast Protocols

  • Service components, which include:

  • Unicast Routing Information Base Module

  • Layer 2 Multicast Module

  • Layer 3 Multicast Module


Layer 2 Protocols

OcNOS includes these Layer 2 features:

  • Virtual Local Area Networks

  • Spanning Tree

  • Carrier Ethernet

  • Port Authentication (802.1x)
