**Fiber Optic** - Gigabit fiber internet connections - **Ethernet** - Dedicated Ethernet circuits - **Leased Lines** - Point-to-point dedicated circuits - **Metro Ethernet** - Carrier Ethernet services - **MPLS** - Multi-Protocol Label Switching - **Dark Fiber** - Customer-owned fiber infrastructure #### Why Wired-Only Focus? - Consistent, predictable performance - Higher throughput capacity (1-100 Gbps) - Lower latency and jitter - No weather/signal degradation - Symmetric upload/download speeds - Enterprise-grade SLAs from carriers ### Load Balancing Algorithms #### Algorithm Options **Round Robin** - Distributes traffic equally across all WAN links - Simple, fair distribution - Best for similar-speed links - No session awareness - Good for general internet traffic **Weighted Load Balancing** - Assigns traffic proportional to link capacity - Example: 70% on 1 Gbps link, 30% on 500 Mbps link - Optimal bandwidth utilization - Configurable weights per link - Dynamic adjustment based on usage **Least Connections** - Routes to WAN with fewest active connections - Ideal for application servers - Session-aware distribution - Best for long-lived sessions - Application-level optimization **Source Hashing** - Routes based on source IP address - Ensures same user uses same WAN - Session persistence guarantee - Consistent routing behavior - No session table required **Spillover (Threshold-Based)** - Primary WAN handles traffic until threshold - Overflow to secondary WANs - Preserves priority link for critical traffic - Cost optimization (expensive vs cheap links) - Manual or automatic threshold setting ### Automatic Failover & Redundancy #### Failover Mechanisms - Instant detection of WAN link failure - Automatic traffic rerouting to healthy links - Session preservation where possible - Return to primary link when restored - Configurable failover policies - Pre-emptive failover on degradation #### Health Check Probes - **ICMP (Ping)** - Basic reachability test - **HTTP/HTTPS** - Web-based health check - **DNS Query** - DNS resolution test - **Custom TCP/UDP** - Application-specific probes - **Multi-target Testing** - Multiple destinations per WAN - **Configurable Intervals** -

Link quality scoring - Automatic link disable on failure ### Session Persistence / Stickiness #### Persistent Session Handling - HTTP cookies for web sessions - Source IP persistence - SSL session ID persistence - Application-level persistence - Configurable timeout periods - Session table synchronization #### Why Session Persistence Matters - Banking/financial transactions remain on same path - VoIP calls don't switch mid-conversation - VPN sessions maintain connection - Streaming media without interruption - Shopping cart consistency - CRM/ERP application continuity ### Policy-Based Routing (PBR) #### Traffic Classification - **By Application** - Route VoIP to low-latency WAN - **By Protocol** - HTTP/HTTPS, FTP, SSH, etc. - **By Source IP** - Department or user-based routing - **By Destination** - Cloud services to specific WAN - **By Port** - Application port-based decisions - **By Time of Day** - Business hours vs after-hours routing #### Policy Examples - **Example 1**: Route all VoIP (SIP/RTP) traffic to lowest-latency WAN - **Example 2**: Route video conferencing to highest-bandwidth WAN - **Example 3**: Route guest network to cheaper secondary WAN - **Example 4**: Route cloud backup to dedicated backup WAN - **Example 5**: Route critical ERP traffic to premium SLA WAN ### Link Weighting & Priority #### Weight Assignment - Proportional to link bandwidth capacity - Quality-based weighting (latency, jitter) - Cost-based priority (expensive vs cheap) - SLA-based weighting - Dynamic adjustment based on real-time metrics - Manual override capabilities #### Priority Configuration -

Low priority ### NAT Handling & Return Path #### Asymmetric Routing Prevention - Outbound traffic tracks WAN interface - Return traffic follows same path - NAT per WAN interface configuration - Policy NAT for specific traffic -
