Aricent RSTP/MSTP – Multiple Instances is a portable software implementation of 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. It provides comprehensive management capabilities.

Figure 1. Aricent RSTP/MSTP - MI Architecture

Features :

• Implements 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.
• 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 effortless integration with Switch Hardware.
• 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.
• Provides multiple instances support for RSTP and MSTP to facilitate Virtual switching.
• Supports Root Guard feature to enhance network reliability, manageability and security by securely enforcing the topology of the switched network.

Benefits :

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