This document serves as the definitive technical reference for the OEM Mini MDU Box platform, detailing its subscriber capacity, VLAN scaling limits, and hardware-level forwarding constraints. Designed for service providers and system integrators, this datasheet provides engineering-level specifications required for network planning, procurement, and deployment in Fiber-to-the-Home (FTTH) and Multi-Tenant Unit (MTU) environments.

CORE INTERNAL TOPOLOGY

The OEM Mini MDU Box is architected around a purpose-built, carrier-grade switching fabric that delivers deterministic performance across all subscriber interfaces. The internal topology is organized into three primary functional planes:

1. DATA PLANE: A non-blocking shared-memory switch fabric with integrated packet processor. The fabric employs a cut-through forwarding architecture with store-and-forward fallback, ensuring sub-microsecond latency for time-sensitive IPTV and VoIP traffic. The forwarding engine maintains a complete Layer 2/Layer 3 forwarding information base (FIB) with hardware acceleration for ACLs and QoS policies.

2. CONTROL PLANE: An integrated ARM-based network processor running a hardened Linux-based operating system. The control plane is isolated from the data plane via dedicated memory and bus interfaces, preventing control traffic storms from impacting subscriber forwarding performance. The management interface supports SNMPv3, CLI, and RESTCONF/NETCONF for full programmability.

3. MANAGEMENT PLANE: Out-of-band management via dedicated MGMT port with separate routing table. This plane includes a sophisticated telemetry engine capable of streaming sFlow/IPFIX data to external collectors for real-time subscriber usage analytics.

SWITCHING SUBSYSTEM CAPABILITIES

The switching subsystem is the heart of the Mini MDU Box, integrating a high-performance Ethernet switch ASIC that provides wire-speed forwarding across all ports simultaneously. Key architectural highlights include:

- SWITCHING FABRIC: The internal fabric operates at a maximum switching capacity of 56 Gbps for the 24-port model and 104 Gbps for the 48-port model, ensuring non-blocking performance under full line-rate traffic loads.

- FORWARDING RATE: The platform supports line-rate 64-byte packet forwarding at 1.488 Mpps per Gigabit port, with aggregate throughput reaching 41.66 Mpps for the 24-port configuration and 83.33 Mpps for the 48-port configuration.

- BUFFER MEMORY: A shared 2 MB packet buffer pool (expandable to 4 MB via internal memory upgrade) provides robust burst absorption capabilities, essential for handling simultaneous subscriber service activations and broadcast traffic.

- MAC ADDRESS TABLE: Hardware-based MAC learning supports up to 16,000 unique MAC addresses, enabling dense subscriber deployment per physical port.

OPERATIONAL ADVANTAGES

The OEM Mini MDU Box delivers significant operational advantages for service providers managing multi-tenant buildings:

1. SUBSCRIBER DENSITY OPTIMIZATION: The platform supports up to 48 active subscriber ports in a compact 1RU form factor, reducing rack space requirements in central offices and distribution hubs by up to 60% compared to traditional access switches.

2. ENERGY EFFICIENT DESIGN: Utilizing IEEE 802.3az Energy Efficient Ethernet (EEE), the platform dynamically adjusts port power consumption based on link utilization. Typical power consumption is rated at 25W for the 24-port configuration and 45W for the 48-port configuration, enabling deployment in environmentally sensitive locations.

3. ZERO-TOUCH PROVISIONING: The Mini MDU Box supports DHCP-based auto-configuration and Trivial File Transfer Protocol (TFTP) firmware upgrades, allowing for rapid, remote deployment without on-site technical intervention.

4. ENHANCED TELECOM RELIABILITY: Features such as per-port hardware-based loopback detection, broadcast/multicast storm control, and bidirectional forwarding detection (BFD) ensure network stability and rapid fault isolation.

SPECIFICATION MATRIX

HARDWARE OVERVIEW

The OEM Mini MDU Box is constructed with a ruggedized steel chassis designed for 19-inch rack or wall-mount installation. The front panel features modular port configurations, LED status indicators for link/activity and system health, and a console port for local management access.

KEY FEATURES

- Subscriber Capacity: Scalable from 8 to 48 subscriber ports per device, supporting both 10/100/1000Base-T copper and 1000Base-X SFP fiber interfaces for flexible last-mile connectivity.

- Multi-VLAN Scaling: Hardware supports up to 4,096 active VLANs (802.1Q) with full Q-in-Q (802.1ad) stacking capabilities for service segmentation. This allows for up to 4,096 unique virtual networks across the subscriber base, essential for multi-service delivery (voice, video, data, and Wi-Fi) per tenant.

- VLAN Limit Per Port: Each physical port can be assigned up to 512 VLAN sub-interfaces simultaneously via 802.1Q trunking, enabling complex multi-service profiles per subscriber.

- Link Aggregation: Support for up to 8 Link Aggregation Groups (LAGs), each containing up to 8 member ports, providing increased uplink bandwidth and link-level redundancy.

- QoS Capabilities: 8 hardware priority queues per port with strict priority and weighted round-robin (WRR) scheduling, ensuring service differentiation for latency-sensitive applications.

- Security: Hardware-based ACLs supporting up to 2,048 access control entries, port-based MAC address filtering, and DHCP snooping for subscriber access control.

- Multicast: Full IGMPv1/v2/v3 snooping with fast leave processing and MVR (Multicast VLAN Registration) for optimized IPTV traffic distribution.
