Technical Specifications

Network Architecture

NELL-IX operates a redundant, high-performance switching infrastructure designed for maximum reliability and low latency. Our network is built on industry-leading equipment with multiple layers of redundancy.

Switching Platform

  • Arista 7280R3 series switches
  • 100G capable ports
  • Sub-microsecond latency
  • Redundant power supplies

Design Philosophy

  • Layer 2 switching fabric
  • No single point of failure
  • Active monitoring and alerting
  • Automated failover capabilities

Technical Specifications

Supported Speeds

  • 1 Gbps 1000BASE-LX/LR
  • 10 Gbps 10GBASE-LR/ER
  • 25 Gbps 25GBASE-LR
  • 40 Gbps 40GBASE-LR4
  • 100 Gbps 100GBASE-LR4

Protocol Support

  • IPv4 & IPv6

    Dual-stack support on all ports

  • Jumbo Frames

    MTU up to 9000 bytes

  • 802.1Q VLANs

    VLAN tagging supported

Security Features

Layer 2 Security

  • • MAC address filtering per port
  • • Storm control (broadcast/multicast/unicast)
  • • ARP and ND snooping
  • • DHCP snooping
  • • Port security enforcement

Route Security

  • • RPKI validation on route servers
  • • IRR-based prefix filtering
  • • Maximum prefix limits
  • • Bogon/martian filtering
  • • AS path validation

Monitoring & Statistics

SNMP

Read-only SNMP access available to members for monitoring their port statistics and traffic patterns.

sFlow

sFlow sampling available for advanced traffic analysis and DDoS detection.

Traffic Graphs

Real-time and historical traffic graphs available through our member portal.

BGP Best Practices

Recommended Configuration

! Example BGP Configuration
router bgp YOUR-ASN
  neighbor ROUTE-SERVER-IPv4 remote-as 11859
  neighbor ROUTE-SERVER-IPv4 description NELL-IX Route Server
  neighbor ROUTE-SERVER-IPv4 maximum-prefix 100000
  neighbor ROUTE-SERVER-IPv4 prefix-list YOUR-PREFIXES out
  !
  neighbor ROUTE-SERVER-IPv6 remote-as 11859
  neighbor ROUTE-SERVER-IPv6 description NELL-IX Route Server IPv6
  neighbor ROUTE-SERVER-IPv6 maximum-prefix 20000

Important Considerations

  • • Always implement prefix filtering - announce only your own prefixes
  • • Set appropriate maximum prefix limits to prevent routing table overflow
  • • Keep your IRR records (RADB, RIPE, etc.) up to date
  • • Register ROAs for RPKI validation
  • • Use BGP communities for selective peering and traffic engineering - see our peering policy for full BGP community documentation
