The Need for ZebOS

What does ZebOS do?
Vividh Siddha

IP Infusion’s ZebOS® Advanced Routing Suite provides a complete implementation for provider bridging (802.1ad) and supports provisioning and configuring VLAN registration tables for mapping Customer VLANs (C-VLAN) to Service VLANs (S-VLAN). ZebOS also supports configuration of VLAN translation tables. An enhanced version of the Rapid Spanning Tree Protocol (RSTP) for Provider Edge (PE) bridges to handle customer spanning tree packets has been implemented. The handling of customer Layer 2 control packets (tunnel, peer or discard) can be configured on a per-port/per-protocol basis.

Metro Ethernet

A Metro Ethernet is a computer network based on the Ethernet standard, which covers a metropolitan area. It is commonly used as a Metropolitan Access Network (MAN) to connect subscribers and businesses to a Wide Area Network (WAN), such as the Internet. Large businesses can also use Metro Ethernet to connect branch offices to their internal networks. The figure contains a simplified model of Ethernet services from a Service Provider, through the User Network Interface (UNI) to the Customer Edge (CE).


Metro Ethernet Modules

802.1ad Provider Bridging – Provider bridging enables a service provider to use the architecture and pro­tocols of IEEE standard 802.1Q to offer the equivalent of separate Local Area Networks (LANs), Bridged LANs, or Virtual Bridged LANs to multiple customers, while requiring no active cooperation between the customers, and only minimal cooperation between individual customers and the service provider.

MEF User-to-Network Interface (UNI) The MEF UNI supports the Metro Ethernet Forum’s UNI require­ments, framework, and functional model for how a UNI reference point operates in a Metro Ethernet Net­work (MEN).
