Network Architecture Overview
All three nodes (BKK06, BKK07, BKK08) participate in our advanced networking infrastructure:
Anycast Implementation
- 100G Backbone: High-speed interconnects between storage nodes
- BGP Routing: Each node operates as a route reflector client
- Dedicated ASN: Independent autonomous system number per edge node
- Service Isolation: Q-in-Q VLAN tagging for traffic segregation
Redundancy Features
- Dual Uplinks: Each node has redundant connections to core routers
- Active-Backup Bonds: Sub-second failover between interfaces
- Path Diversity: Multiple routing paths for fault tolerance
- VLAN Segmentation: Separate VLANs for management, storage, and service traffic
Performance Optimization
- Hardware Offload: Intel E810-C NICs provide advanced packet processing
- NUMA Awareness: Memory and network affinity for optimal performance
- Jumbo Frames: MTU 9000 enabled on storage network
- Flow Control: Configured for lossless Ethernet on storage paths
