ZebOS by IP Infusion Inc.
ZebOS provides a complete suite of networking protocol software supporting Layer 2 (L2), Layer 3 (L3), unicast, multicast, Multi-Protocol Label Switching (MPLS) and Metro Ethernet standards. It supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) networks as well as a number of transition technologies which enable seamless transport of IPv6 traffic over existing IPv4 networks. ZebOS is well-positioned not only to support core, edge and access routing and switching platforms in provider and enterprise networks, but also to act as the standard routing and switching platform for an entire range of future IPv6-enabled devices. These include Small Office Home Office (SOHO) gateways, wireless, access and security devices, as well as devices that support Virtual Private Network (VPN) and Voice-over-Internet Protocol (VoIP) technologies requiring high Quality of Service (QOS) and leading-edge bandwidth management.
All ZebOS components benefit from an industry-leading validation and testing program, including thousands of tests run internally, as well as interoperability testing at industry events and conformance testing at independent laboratories.
ZebOS Network Platform
The ZebOS Network Platform includes the Hardware Abstraction Layer (HAL) and the Platform Abstraction Layer (PAL) to enable communication with the underlying operating system or network processor for forwarding table updates. The ZebOS Network Platform management interface software provides customers with ease of management, configuration and operation, offering a comprehensive set of tools to manage all routing and switching protocols.
The ZebOS Network Platform also offers a High Availability (HA) Solution which provides the control plane redundancy necessary to meet the demanding 99.999% or 99.9999% uptime requirements of carrier networks. Features include stateful switchover operations (SSO) for a variety of HA configurations (1+1, 1:1, m:n, or simplex); SSO using replication for ZebOS Spanning Tree Protocol (STP) and Link Aggregation Control Protocol (LACP); and SSO using replication of Routing Information Base (RIB) to support Non-Stop Routing (NSR). The ZebOS HA Solution comes pre-integrated with the ENEA Element middleware via a versatile Checkpoint Abstraction Layer (CAL). Management functionality is similarly abstracted through a Management Abstraction Layer (MAL). This pre-integrated platform provides industry-leading checkpointing and is primed to provide In-Service Software Upgrades (ISSU). The CAL can also be used to extend the environment to support other commercial or proprietary HA middleware solutions.
ZebOS Hardware Services Layer (HSL)
The ZebOS Hardware Services Layer (HSL) is an array of software modules, each designed and integrated with an industry-leading merchant silicon solution and operating system. The ZebOS HSL provides a comprehensive forwarding plane implementation supporting Layer 2, Layer 3 (both IPv4 and IPv6), multicast and MPLS/Traffic Engineering. When combined with the ZebOS Network Platform Layer 2, Layer 3, multicast and MPLS networking protocol modules for the control plane, the ZebOS HSL provides a full system solution for enterprise switching, Metro Ethernet, core, access, edge, mobile wireless and advanced IP services applications.
The ZebOS HSL modules are fully system tested with the ZebOS Network Platform protocol software on leading merchant silicon reference platforms. The well-defined and extensible API between the ZebOS Network Platform (control plane) and the ZebOS HSL (forwarding plane), called the Hardware Abstraction Layer (HAL), accommodates easy addition of custom features and applications and easy integration to virtually any silicon and operating system environment.
ZebOS Network Platform Profiles
The ZebOS Network Platform Profiles leverage the industry’s most comprehensive suite of robust, standards-based IPv4 / IPv6, unicast, multicast, MPLS and Metro Ethernet protocol modules to create highly optimized solutions designed to accelerate time to market for specific application segments. Each individual protocol module takes full advantage of the services and clean APIs of the ZebOS Network Platform to eliminate specific hardware, OS and middleware dependencies. Each protocol in a module group is typically implemented as a distinct process to ensure robustness and to eliminate dependencies on other protocol modules.
The following profiles are typical examples; it is possible to construct other variations focused on specific applications.
Enterprise Switching Profile
The Enterprise Switching Profile's focus is providing all the required Layer 2 software support for use within the enterprise. It includes Ethernet Media Access Control (MAC) bridging, STP, Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), Virtual LAN (VLAN) and hardware forwarding APIs, Internet Group Management Protocol (IGMP) Snooping, GARP Multicast Registration Protocol (GMRP), GARP VLAN Registration protocol (GVRP), Port and Protocol VLAN classification (802.1v), 802.1x Port Authentication and Link Aggregation (802.3ad).
This profile is useful in requirements that are well satisfied by Layer 2 only networks.
ZebOS Advanced Platform Profiles
Enterprise Routing Profile
The Enterprise Routing Profile includes key routing protocols such as Routing Information Protocol (RIP) and Open Shortest Path First version 2 (OSPF) hybrid switching routing that enables synergistic interaction between the L2 and L3 protocols. The hybrid switch router that can take advantage of the fast path forwarding provided by today's advanced networking hardware. Typical routed networks provide a greater level of segregation that might be attractive in enterprise networks.
Carrier Ethernet Profile
The Carrier Ethernet Profile consists of modules from the Layer 2 and Metro Ethernet groups. The Profile focuses on providing Ethernet services - E-LINE, E-LAN and their virtual counterparts - in full compliance with Metro Ethernet Forum (MEF) standards 9, 10.1, 13 and 19. Even though Carrier Ethernet is primarily a Layer 2 definition and service, several alternatives exist for service providers in making the service available to their subscribers. For example, an Original Equipment Manufacturer (OEM) could combine the Layer 2 and the Metro Ethernet module groups to provide a low-cost Carrier Ethernet solution that is relatively simple because it contains only Layer 2 control protocols. Implementations such as VLAN tagging, Provider Bridging and Provider Backbone Bridging only make use of Layer 2 control plane protocols.
ZebOS Network Platform also scales to support a broad range of more sophisticated implementations. Ethernet over MPLS, for example, requires the use of Layer 3 control plane protocols such as Label Distribution Protocol (LDP).
Provider Edge Profile
The Provider Edge (PE) Profile, sometimes also called the network-facing provider edge (N-PE), consists of modules from a number of module groups: Layer 2, Layer 3 (IPv4 and IPv6), Multicast (IPv4), VR (IPv4), Metro Ethernet, MPLS (IPv4), HA Layer 2 and HA Layer 3. The Profile provides IP-layer services such as IP VPNs using virtual routers, IP VPNs using MPLS/BGP, IPv6 islands connected by an IPv4 core network and IPv6 VPNs through an IPv4 core. Provider Edge devices can also be called upon to provide Layer 1 and Layer 2 services that make use of the same Layer 3 control plane protocols as MPLS.
For example, an OEM could combine the Layer 2, Layer 3, IPv6/IPv4 Dual Stacking, Multicast and HA module groups to provide an effective PE solution that is able to serve well in the transition to IPv6.
(Note: A Provider Edge Profile that is focused on a pure IPv4 network is a simpler subset of the above example.)
IPTV/VoD Profile
By combining Multicast, Metro Ethernet, Layer 3 and MPLS module groups, an OEM can create a very effective Internet Protocol Television (IPTV) and/or Video-on-Demand (VoD) solution. IPTV functionality requires a very effective multicast support, whereas VoD requires high quality of service unicast capability. A set-top box targeted to the home is a good candidate for this functionality.
