BGP, Transit & Multihoming
Upstream integration, route policy, prefix filtering, local preference, prepending, communities, failover, and traffic engineering.
ISP & Service Provider Consulting
Engineering for Networks
That Carry Networks.
Routing, peering, transit, architecture, automation, and operational support for small and regional Internet service providers that need experienced engineering without another full-time senior hire.
Built for Growing Providers
Deep network expertise when your next problem is bigger than routine operations.
Whether you're adding upstream capacity, connecting to an Internet exchange, redesigning an IGP, improving routing policy, or troubleshooting a difficult production issue, JZ Technology Services can provide focused engineering help without forcing you into a traditional managed-services model.
The goal is to work alongside your team, solve the problem, document the design, and leave you with an environment that is easier to operate.
Service Provider Capabilities
From the edge to the core.
Practical engineering across the routing, transport, and operational systems that keep provider networks moving.
Peering & Internet Exchanges
IX connectivity, bilateral peering, route-server integration, filtering, policy design, and growth planning.
IGP & Core Architecture
OSPF and IS-IS design, metric strategy, convergence, redundancy, routed-core modernization, and topology reviews.
Network Design & Expansion
Core and aggregation architecture, new POPs, inter-site connectivity, NNIs, customer handoffs, capacity planning, and migrations.
Switching & Infrastructure
Core and aggregation switching, NNIs, VLAN transport, customer handoffs, LACP, redundancy, and high-capacity infrastructure design.
Firewall & VPN Engineering
Edge security, management-plane access, site connectivity, IPsec VPNs, NAT, segmentation, high availability, and firewall troubleshooting.
Monitoring & Automation
BGP and interface monitoring, SNMP and telemetry, Grafana dashboards, alerting, NetBox/IPAM, Python automation, configuration validation, and operational tooling.
IP Addressing & RIR Strategy
IPv4 and IPv6 planning, ASN and prefix strategy, routing registry considerations, geofeeds, and RIR-related technical guidance.
Common Engagements
Bring in extra engineering where it has the most impact.
JZ Technology Services can supplement your existing technical team for a defined project, an architecture review, or an escalation that needs deeper routing experience.

How I Work
Engineering support without taking over your network.
Project Engineering
Defined design, migration, implementation, or expansion work with clear technical deliverables.
Architecture Review
An independent look at topology, routing policy, redundancy, capacity, and operational risk before you make the next change.
Escalation & Troubleshooting
Additional engineering depth for routing instability, performance problems, outages, and issues that have resisted normal troubleshooting.
Ongoing Engineering Retainer
Regular access to experienced network engineering for providers that need another technical resource without another full-time position.
Multi-vendor experience: Cisco, Juniper, and mixed service-provider environments. Recommendations are driven by the network requirement, not a preferred vendor.
