PRODUCT OVERVIEW & MARKET POSITIONING
The Small Business Multi-WAN Load Balancing Router (Model Series: SB-R3000) represents a paradigm shift in edge connectivity for the distributed enterprise. Designed to eliminate single points of WAN failure and aggregate diverse broadband links (Fiber, DSL, 5G/LTE), this platform delivers carrier-grade link redundancy at a cost-optimized entry point.

CORE ARCHITECTURE & CHASSIS DESIGN
The SB-R3000 is housed in a compact, fanless 1RU hardened metal chassis measuring 9.8 x 6.2 x 1.7 inches. The architecture is built around a dedicated Network Processing Unit (NPU) offloading session-based load balancing from the main CPU. Passive thermal dissipation enables silent operation in open office environments while supporting 0°C to 45°C ambient temperatures.
HARDWARE FEATURE MATRIX
– WAN PORTS: 4x Gigabit Ethernet (Copper) configurable as either WAN or LAN
– LAN Switching: 4x Gigabit Ethernet (Copper) with integrated 802.1Q VLAN
– USB Extension: 1x USB 3.0 for LTE modem failover or configuration backup
– Console Port: 1x RJ45 Serial (115200 default)
– Load Balancing Algorithms: Weighted Round Robin, Least Latency, Packet Hash, and Failover Only
– Session Persistence: Source IP, Destination IP, and Round Robin sticky modes

PROTOCOL & INTEROPERABILITY LAYER
The control plane supports full dynamic routing with RIP v1/v2, static route leak, and Policy-Based Routing (PBR) to steer traffic by application signature or DSCP tag. The unit acts as a transparent bridge for PPPoE passthrough and includes Deep Packet Inspection (DPI) for application-aware load distribution. IPsec VPN performance is hardware-accelerated up to 350 Mbps with concurrent 30 VPN tunnels.
QUALITY OF SERVICE & TRAFFIC MANAGEMENT
Per-port hierarchical QoS with 8 hardware queues supports Low Latency Queuing (LLQ) and Class-Based Weighted Fair Queuing (CBWFQ). The SB-R3000 can shape traffic at 1Kbps granularity and includes Smart Queue Management (SQM) for bufferbloat mitigation.
