Internet Aggregation Buying Guide

Buying Guide for Internet Aggregation Software

Internet aggregation software, also known as multi-WAN or link aggregation, combines multiple Internet connections into a single, more robust, and higher-performing network. This technology is crucial for businesses requiring uninterrupted connectivity, maximizing bandwidth, and ensuring application performance, especially in environments where a single ISP connection may be unreliable or insufficient.

What Internet Aggregation Software Does

At its core, Internet aggregation software intelligently manages and routes traffic across several distinct Internet Service Provider (ISP) links. It doesn't just fail over to a backup connection; it actively utilizes all available bandwidth simultaneously. This provides:

  • Increased Throughput: By combining the speeds of multiple connections, businesses can achieve higher overall download and upload speeds than any single connection offers.
  • Enhanced Reliability and Redundancy: If one internet connection fails, traffic is automatically and seamlessly rerouted across the remaining active connections, preventing downtime and maintaining business continuity.
  • Optimized Application Performance: Traffic can be intelligently steered based on application requirements, prioritizing critical data and ensuring low latency for sensitive applications like VoIP or video conferencing.

Key Features to Evaluate

When selecting an Internet aggregation solution, consider these essential features:

  • Load Balancing Algorithms:
    • Round Robin: Distributes connections sequentially across available links.
    • Least Connections: Directs new connections to the link with the fewest active connections.
    • Application-Aware Routing: Prioritizes specific application traffic over certain links.
    • Policy-Based Routing: Allows administrators to define rules for traffic distribution based on source/destination, application type, or QoS tags.
  • Failover and Failback Mechanisms:
    • Instantaneous Detection: Ability to quickly identify link failures (e.g., within milliseconds) and reroute traffic.
    • Seamless Failover: Ensures ongoing sessions are not interrupted during a link failure.
    • Automatic Failback: Returns traffic to the primary link once it recovers, without manual intervention.
  • Quality of Service (QoS):
    • Traffic Prioritization: Assigns higher priority to critical applications (e.g., VoIP, video conferencing) to ensure their performance.
    • Bandwidth Allocation: Guarantees a minimum or maximum bandwidth for specific traffic types or departments.
  • Monitoring and Reporting:
    • Real-time Link Utilization: Dashboards showing bandwidth consumption for each link.
    • Performance Metrics: Latency, jitter, and packet loss statistics for each connection.
    • Alerting: Customizable notifications for link failures, performance degradation, or unusual traffic patterns.
    • Historical Data: Logs and reports for capacity planning and troubleshooting.
  • VPN Integration: Support for aggregating VPN tunnels for increased secure connection bandwidth and reliability.
  • Centralized Management: A single interface to configure, monitor, and manage multiple aggregation devices or instances across different locations.

Use Cases

Businesses leverage Internet aggregation for various reasons:

  • Branch Office Connectivity: Ensuring highly available and fast internet for remote offices.
  • Retail and POS Systems: Guaranteeing uptime for transaction processing.
  • Media and Content Creation: Accelerating large file transfers and uploads.
  • Cloud Application Access: Optimizing connectivity to SaaS applications and cloud platforms.
  • Manufacturing and IoT: Maintaining stable connections for operational technology (OT) and sensor data.
  • Businesses in Underserved Areas: Combining multiple lower-speed connections (e.g., DSL, cellular, satellite) to achieve usable broadband.

Implementation Considerations

  • Existing Infrastructure: Assess compatibility with current routers, firewalls, and network topology.
  • ISP Diversity: Ensure you are using different ISPs for maximum redundancy, as common points of failure can negate benefits if links share infrastructure.
  • Deployment Model:
    • Hardware Appliance: Dedicated device for aggregation, typically higher performance.
    • Virtual Appliance: Runs on existing virtualization platforms, offering flexibility and scalability.
    • Cloud-Based Service: Managed service, often used with SD-WAN solutions, offloading infrastructure management.
  • Network Latency: Consider how aggregation might affect latency for specific applications, especially when combining links with vastly different characteristics.

Pricing Models

Internet aggregation software typically follows these pricing structures:

  • Per-Device/Per-Appliance: A one-time purchase or annual license fee per hardware or virtual appliance.
  • Per-Bandwidth/Throughput: Pricing tiers based on the aggregated bandwidth supported by the solution.
  • Per-Link: Cost scales with the number of aggregated internet connections.
  • Subscription-Based (SaaS): Monthly or annual fees, often including support and updates, common for cloud-managed solutions.
  • Feature-Based Tiers: Basic features at lower cost, with advanced capabilities (e.g., deeper QoS, advanced reporting) in higher-priced tiers.

Selection Criteria

  1. Performance Requirements: What combined bandwidth do you need? What are your latency and uptime targets?
  2. Budget: Align features with allocated budget for hardware, software licenses, and ongoing subscriptions.
  3. Scalability: Can the solution grow with your business needs as more bandwidth or locations are added?
  4. Ease of Management: Look for intuitive interfaces and robust monitoring capabilities.
  5. Vendor Support and Reputation: Evaluate vendor responsiveness, documentation, and customer reviews.
  6. Integration: How well does it integrate with your existing network security and management tools?
  7. Future-Proofing: Does the solution support emerging technologies like 5G or advanced SD-WAN capabilities?

By carefully evaluating these factors, businesses can select an Internet aggregation solution that delivers significant improvements in network reliability, performance, and operational efficiency.
