Aricent TB/STP is a portable software implementation of Transparent Bridging, IGMP Snooping and the Spanning Tree Algorithm including Rapid Spanning Tree and Multiple Spanning Tree support. The software is portable to different operating systems and switch hardware using well-defined external interfaces. Aricent TB/STP has provision for supporting Link aggregation and Port authentication. It provides comprehensive management capabilities.

Features :

• Implements Transparent Bridging (802.1D) and the Rapid Spanning Tree Protocol for Rapid Recovery (802.1w), supporting recovery in the order of less than a second.
• Supports Multiple Spanning Tree Instances (802.1s) to enable more than one forwarding path by associating one or more VLAN Ids to each of the spanning tree Instance.
• Supports all features specified in RFC 1493 for transparent bridges.
• RSTP and MSTP bridges are designed to flexibly interoperate with bridges running in STP/RSTP/MSTP modes.
• Supports all features specified in the draft MIB for RSTP.
• Requires minimum efforts, during integration with external modules (Port Based Network Access Control, Link Aggregation and VLAN/GARP).
• Generic set of NP APIs are provided for all the components of TB/STP for effortless integration with Switch Hardware
• Provides filtering based on protocol, MTU, source and/or destination MAC addresses.
• Controls the forwarding of Multicast packets using the information learnt by IGMP Snooping.
• Can be easily integrated with different types of switch hardware from various vendors.
• Provides support for configuration and management through SNMP & CLI.
• Conforms to Future Software Architecture for Portability (FSAP2), thus ensuring a highly portable code, which uses flexible buffer and timer management libraries.

Benefits :

Aricent TB/STP reduces the time to market for OEMs and VARs who wish to incorporate the TB/STP functionality into their switching/routing devices.
