Network Topology
A typical Layer-2 circuit involves: Site A (Remote Location):
Starlink terminal installed on-site
Starlink Gateway configured with VLAN tagging
Customer equipment (router/switch) connected to gateway
Secure Private Network Interconnect Over Satellite
Layer-2 private circuits deliver dedicated point-to-point connectivity for enterprises requiring deterministic network performance, maximum security, and private traffic isolation. Ideal for banking core systems, payment processing, data centre interconnects, and regulated industries with strict compliance requirements.

What is Layer-2 / Private Circuits?
Layer-2 private circuits create transparent LAN extensions between geographically separated locations as if both sites were connected to the same physical switch. Traffic travels in a dedicated VLAN that never touches the public internet, providing the highest level of security and predictable performance.
Fieldbase delivers Layer-2 circuits using Starlink's LEO satellite constellation combined with our direct peering agreement with SpaceX. We create VLANs from your remote site through satellites to our infrastructure at partner data centres, where you can cross-connect to your own equipment.
Why you need Layer-2 Private Circuits
Performance
Latency: 20–40ms (typical)
Jitter: <10ms
Packet Loss: <0.1% under normal conditions
Throughput: Dedicated bandwidth per VLAN based on Starlink plan
Physical constraints (building structure, cable routing, equipment placement)
Security
AES-256 encryption for all traffic
Private VLAN circuits with no internet exposure
Traffic never traverses public networks
Suitable for PCI-DSS, HIPAA, SOX compliance frameworks
Availability
99.5% uptime SLA (standard tier)
99.7% uptime SLA (premium tier with redundant paths)
Optional: Dual-circuit redundancy for mission-critical applications
Integration
Seamless integration with MPLS networks
Compatible with SD-WAN architectures
Supports BGP routing for dynamic failover
QoS (Quality of Service) support for traffic prioritization
How Layer-2 Circuits work
How organizations use it
Banking & Financial Services
Connect remote bank branches to core banking systems using private Layer-2 circuits. Support:
ATM connectivity and transaction processing
Branch teller systems and customer databases
Payment processing and clearing
Regulatory compliance (data sovereignty, encryption requirements)
Layer-2 circuits ensure banking traffic never traverses the public internet, reducing exposure to cyber threats and meeting regulatory requirements for private connectivity.
Data Centre Interconnect (DCI)
Establish private connectivity between geographically distributed data centres:
Data replication for disaster recovery
Virtual machine migration between facilities
Storage area network (SAN) extension
Management and administrative access
Layer-2 DCI allows you to treat remote data centres as a single logical infrastructure stretching VLANs and subnets across sites.
Deployment process
A streamlined deployment process designed to deliver secure enterprise connectivity with minimal disruption.
Why choose layer 2 over layer 3?
Use Layer-2 Private Circuits When:
You need transparent LAN extension (remote site appears on same subnet)
Security or compliance requires traffic to bypass the internet entirely
You want to manage all routing and firewalling on your own equipment
Applications require Layer-2 adjacency (broadcast domains, multicast)
You need deterministic, predictable network performance
Use Layer-3 Internet Service When:
You need standard internet access (web, email, cloud software)
You're comfortable using VPN for secure remote access
Simplicity and rapid deployment are priorities
Cost is a primary concern (Layer-3 is typically less expensive)
