ExtremeWare® Network Operating System

ExtremeWare Operating System (OS) delivers the comprehensive security features, intuitive management and robust network service required in today’s demanding service provider and enterprise networks. A field-proven OS, ExtremeWare has benefited from extensive deployment in a wide range of network topologies and service applications. This has enabled continuous refinement of ExtremeWare, establishing a basis for resilient networks, capable of voice-quality connections. Management complexity can be a common hindrance associated with the growth and repurposing taking place as service providers roll out new services and enterprises centralize networks and continue to build out applications such as storage and data warehousing. This is complicated by the integration of new applications such as wireless and Voice over IP.

ExtremeWare starts by establishing a secured network environment. Advanced features such as policy-based network access and Denial of Service protection help to meet the high expectations of network security. This foundation of a well-guarded and highly available network infrastructure is essential in today’s business environment, especially as the stakes rise due to compliance requirements and new security legislation. ExtremeWare simplifies this next wave of network growth with powerful features such as LLDP device discovery, UniStack stacking technology and sFlow flow-based monitoring that simplify the setup and maintenance of large convergence networks. Its comprehensive set of Layer 2 and Layer 3 control protocols provides flexibility on the design of highly resilient networks.

  • ExtremeXOS® compatible functionality and CLI
  • Comprehensive set of Layer 2 and Layer 3 resiliency protocols, including EAPS
  • Ease of management and monitoring with support for LLDP and sFlow
  • Network access authentication integrated with host integrity checking, control and management plane security

Benefits & Features

ExtremeWare guards access to the network through authentication, Network Login/802.1x, and host integrity checking. It hardens the network infrastructure with Denial of Service (DoS) protection and provides security using authentication and encryption. Its sFlow data monitoring supports provides Layer 2-7 visibility into the network, including statistics on which applications are running over your network, biggest talkers, etc.

ExtremeWare scales networks simply and transparently using UniStack™—Layer 2 and Layer 3 switch stacking. Its leading LLDP support provides vendor independent discovery. Its EAPS protocol provides network resiliency for carrier and voice grade networks, enabling continued uptime for all mission critical applications in your network.

  • Advanced data and equipment monitoring capabilities
  • Secured access to your network
  • Integration with leading host integrity checking solutions
  • Carrier and voice grade network resiliency with EAPS protocol
  • Powerful stacking capability simplifies management

EAPS – Carrier and Voice Class Ethernet Resiliency

To support the triple play of voice, video and data, networks must deliver highly-reliable transport for the three different application types. Network failure events should be completely transparent to the end users, making interruptions in voice, video or data applications imperceptible. The answer to the challenge of service resiliency over Ethernet networks is Ethernet Automatic Protection Switching (EAPS) from Extreme Networks.

A service-aware ring-based protection scheme, EAPS uses a standard Ethernet MAC and is capable of meeting the carrier class benchmark of 50ms. Its rapid failover speed is perfect for VoIP deployments, as calls can stay up. EAPS also supports a variety of complex network topologies, including dual-attached rings and subtended rings giving Metro Ethernet service providers and enterprise networks greater flexibility for protecting a broad variety of network architectures and topologies.

  • Rapid failover, voice call tolerant
  • Simple and flexible ring-based network design
  • Tolly Group tests demonstrate toll-quality voice across 5 types of failures
  • Installed and operating in hundreds of converged networks
