DECnet Router Server V1.2 SPD Oct88

The DECnet Router Server, Version 1.2, is a software product designed to provide DECnet routing functions within a network. It runs on Digital's Ethernet Communications Server hardware, primarily connecting DECnet nodes on an Ethernet LAN to other nodes located off the Ethernet via synchronous and asynchronous communication lines.

Key functions and features include:

• Routing Capabilities: Supports both Phase III and Phase IV DECnet environments, enabling routing between different areas (Level 2) and within the same area (Level 1). It uses adaptive routing to determine the least-cost path for message forwarding and can act as a "designated" router on an Ethernet segment, offloading routing tasks from host computers.
• Protocol Support: Implements the Digital Data Communications Message Protocol (DDCMP) Version 4.0 for full/half-duplex communications over point-to-point lines.
• Network Management: Provides remote utilities for displaying statistics, controlling server operations (e.g., starting/stopping lines, software loading), logging events, and performing network tests.
• Connectivity: Interfaces with various synchronous and asynchronous line cards (e.g., DUP11, DMC11, DMR11, DMV11, DZ11 series) via RS-232-C/CCITT V.24 and V.35 cables.
• Performance: Can handle up to 63 DECnet areas and 1023 nodes. It supports a maximum aggregate line throughput of 500 kilobits per second across up to 32 lines, and processes up to 140 packets per second for routing.
• Operation: Software and diagnostics are down-line loaded from a host system on the Ethernet. It's configurable via host-based files, allowing for system-level parameter adjustments.

The product requires specific Digital VAX, MicroVAX, or PDP-11 systems to act as load/dump hosts, running compatible VMS, MicroVMS, or RSX-11M operating systems, along with the appropriate DECnet software. It is warranted for use only with supported Phase III and IV DECnet products by DIGITAL.
