IP Infusion Releases ZebOS Advanced Routing Suite with Layer 2 Protocol

1/7/2004 - IP Infusion, a leading provider of intelligent network software for enhanced IP services, announced the availability of ZebOS® Advanced Routing Suite (ARS) version 6.1 with significant enhancements to its Layer 2 protocol suite and management interface product offerings. ZebOS ARS now includes support for Multiple Spanning Tree Protocol (802.1s), Link Aggregation (802.3ad), GARP Multicast Registration Protocol (GMRP), and IGMP Snooping; enhancements to VLAN support with Port and Protocol VLAN classification (802.1v) and GARP VLAN Registration Protocol (GVRP) as well as Independent VLAN Learning. Also available in ARS 6.1 are basic access and IPv6 tunneling and transition management interface modules.

“As the enterprise switching and metro edge markets continue to expand and demand more advanced functionality, equipment vendors are facing tremendous pressure not only to deliver highly sophisticated and scalable solutions but also to do so with shorter development cycles and reduced costs,” said Nick Keating, President and CEO of IP Infusion. “Now with our new feature-rich Layer 2 software and widely used Layer 3 protocol suite, IP Infusion is addressing these ever growing needs and offers one of the most complete, flexible and modular routing and switching software solutions in the industry.”

About ZebOS Advanced Routing Suite Version 6.1 Features
Layer 2 Protocol Modules
802.1s Multiple Spanning Trees
The Multiple Spanning Tree Protocol (MSTP) is a supplement to 802.1Q. It allows VLAN bridges to use multiple spanning trees by providing the ability for traffic belonging to different VLANs to flow over potentially different paths within the virtual bridged LAN.

802.1v Port and Protocol Classification
Port and Protocol Classification is an amendment to 802.1Q that describes enhancements to allow for classification of incoming packets by methods other than source port. Specifically, it defines rules for classification based on data-link layer protocol identification.

GVRP - GARP VLAN Registration Protocol
The GARP VLAN Registration Protocol (GVRP) provides 802.1Q VLAN pruning and dynamic VLAN creation. A switch can exchange VLAN configuration information with other GVRP switches, prune unnecessary broadcast and unknown unicast traffic, and dynamically create and manage VLANs.

GMRP - GARP Multicast Registration Protocol
The GARP Multicast Registration Protocol (GMRP) provides multicast pruning and dynamic group membership for multicast. A switch can exchange multicast group information with other GMRP switches, prune unnecessary broadcast traffic, and dynamically create and manage multicast groups.

Internet Group Multicast Protocol (IGMP) Snooping
A switch supporting IGMP snooping can passively snoop on IGMP packets to learn the IP Multicast group membership. With IGMP snooping multicast traffic of a group is only forwarded to ports that have members of that group. IGMP snooping generates no additional network traffic.

802.3ad Link Aggregation
Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group (LAG), such that a MAC Client can treat the Link Aggregation Group as if it were a single link.

Management Interfaces
Basic Access
The Basic Access Module offers a series of interfaces that enable equipment vendors to easily configure and manage network services featured in the Linux operating system, such as DNS, DHCP, NAT, ACL, and PPPoE. As a result they are able to easily and rapidly integrate access software into their products and pass on the ease of manageability to their end users.

Tunneling and Transition
The IPv6 Tunneling & Transition Module provides tools and a command line interface (CLI) via the ZebOS Network Services Module to configure and set parameters of IPv6 to IPv4 transition and tunneling protocols such as 6to4, Intra-Site Automatic Tunnel Addressing Protocol (ISATAP), Generic Routing Encapsulation (GRE), and IP-in-IP encapsulation protocols. These features deliver enhanced performance, easy integration and management for access product OEMs/ODMs.
