Architecture Overview

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

• MPLS: LDP, RSVP, L2VPN, L3VPN

• 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

• Multi Protocol Label Switching 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

• Data Center Bridging

• Port Authentication (802.1x)

• Link Aggregation (802.1AX)

• Multi-Chassis Link Aggregation 

Layer 3 Protocols

OcNOS supports these IP protocols:

• Border Gateway Protocol

• Open Shortest Path First

• Routing Information Protocol

• Intermediate System to Intermediate System

• Virtual Router Redundancy Protocol

• Bidirectional Forwarding Detection

In addition to the standard Layer 3 routing protocols, OcNOS offers:

• Virtual Routing (VR) support

• Virtual Routing and Forwarding (VRF) support

• Constrained Shortest Path First (CSPF) topology support for the Open Shortest Path First (OSPF) and Intermediate System-to-Intermediate System (IS-IS) protocols
