Access Stack Node (ASN)

Extends Network Connectivity

Ensures Network Availability

Maintains Network Performance

Simplifies Network Manageability

Overview

The Wellfleet Access Stack Node (ASN) from Bay Networks introduces an innovative stackable router architecture that provides cost-effective, growth-oriented solutions for remote, regional, and departmental locations. The ASN is the first router designed to provide seamless integration of multiple units stacked together for management as a single router. This architecture makes managing a growing internetwork easier because adding interfaces beyond a unit's capacity does not require adding more routers - and complexity - to the network's topology. A stack of four ASNs supports up to 24 network interfaces and forwarding performance of up to 200,000 pps, providing a superior path for growth.

The ASN easily integrates into the enterprise internetwork, supporting all major LAN and WAN media and protocols. The ASN's LAN and WAN interfaces (Ethernet, Token Ring, FDDI, Synchronous, and ISDN BRI) meet the connectivity needs for remote and campus offices by offering the modularity and flexibility to build configurations with industry-leading price/performance. The Motorola 68040 processor in the ASN's highly integrated design easily maintains high forwarding and filtering rates, regardless of the number of protocols and network interfaces used - even when processing SNMP management inquiries. The ASN supports all major network and bridging protocols, including DLSw for industry-standard IBM integration. Using Synchronous interfaces for SDLC allows further consolidation of IBM SNA and LAN traffic. For mission-critical applications in remote offices, the ASN supports Dial Back-up and Bandwidth-on-Demand. Uniform Traffic Filters, Traffic Prioritization, and Data Compression optimize bandwidth and maximize traffic control. The ASN's fault-resilient system software ensures high network availability. Wellfleet EZ-Install, EZ-Configure, and EZ-Update simplify ASN installation, configuration, and software maintenance. The ASN is easily configured and monitored via Bay Networks Optivity/Internetwork, which combines three applications - Site Manager, RouterMan, and PathMan - to form a seamless integrated router management package for Wellfleet routers.

The ASN complements the Wellfleet Access Node (AN), Backbone Link Node (BLN), and Backbone Concentrator Node (BCN) to satisfy all connectivity, performance, and availability requirements ranging from cost-effective workgroup or remote site access to high-performance, highly available network hubs. The Wellfleet router family connects up to 52 network interfaces and delivers aggregate system forwarding performance up to 760,000 pps.
