01 / Campus
Enterprise & campus networks
Consistent wired and wireless access, resilient switching, identity-aware admission, and segmentation that supports operations.
NET.01 // Network Engineering
NetworkEngineering.
Engineer the fabric that keeps the mission connected.
Vetrotac designs resilient, secure, and programmable networks across campus, WAN, data center, cloud, wireless, and mission-edge environments. We connect different platforms through one coherent operating architecture.

NET.01 // CAPABILITY OVERVIEW
From foundational connectivity to operational assurance.
A network must do more than move traffic. It must recover predictably, enforce policy, expose its operating state, and remain understandable to the people responsible for it.
Our engineering begins with mission flows, failure domains, trust boundaries, and lifecycle constraints—not a preferred hardware catalog.
02 / WAN
WAN & mission edge
Routing policy, carrier diversity, SD-WAN, encrypted transport, QoS, and predictable recovery between distributed sites.
03 / Fabric
Data center fabrics
Underlay and overlay design, ECMP, VXLAN/EVPN, multi-tenancy, interconnects, and explicit failure boundaries.
04 / Hybrid
Cloud & hybrid connectivity
Private connectivity, transit routing, resilient egress, hybrid name resolution, and controlled paths between workloads and users.
05 / Services
Core network services
DNS, DHCP, IPAM, NTP, IPv4/IPv6 planning, out-of-band management, and services designed to survive infrastructure faults.
06 / Assurance
Observability & assurance
Telemetry, flow records, logs, packet evidence, configuration state, capacity baselines, and controlled failover validation.
NET.01 // ENGINEERING FIELDS
One discipline. Eight connected fields.
Each area is designed in the context of the full network, not as an isolated product deployment.
Create a consistent foundation for users, devices, and critical services across access, distribution, core, and wireless environments.
Engineering focus
Hierarchical and fabric-based campus design, wired and wireless access, redundancy, 802.1X, guest isolation, and policy segmentation.
NET.01 // TECHNOLOGIES & METHODS
Standards first. Platforms in context.
Technology is selected for the operating requirement, lifecycle, interoperability, and support model. Protocols and data models remain the connective tissue across vendors.
01 / Routing & transport
Routing & transport
Control reachability, path selection, convergence, and service quality.

02 / Switching & fabrics
Switching & fabrics
Build predictable local and data center forwarding domains.
// Ethernet// VLAN// VRF// LACP// MLAG// VXLAN// EVPN
03 / Wireless & secure access
Wireless & secure access
Tie access decisions to identity, device posture, and policy.
// Wi-Fi// 802.1X// RADIUS// NAC// MACsec// ZTNA
04 / Network services
Network services
Protect the shared services every application path depends on.
// DNS// DHCP// IPAM// NTP// Load distribution
05 / Operations & assurance
Operations & assurance
Observe traffic, behavior, configuration, capacity, and faults.
// SNMPv3// Syslog// NetFlow/IPFIX// Telemetry// Synthetic tests// Packet analysis
06 / Programmability
Programmability
Express intent and validation through portable automation interfaces.
// Python// Ansible// Terraform/OpenTofu// Nornir// Git// CI/CD// NETCONF// RESTCONF// gNMI// YANG
07 / Illustrative platform environments
Illustrative platform environments
Apply standards-led engineering across routing, switching, wireless, security, cloud, and open systems.
// Cisco// Juniper// Arista// HPE Aruba// Extreme// Nokia// Palo Alto// Fortinet// F5// Azure/AWS/GCP// Linux/open source
Illustrative technology landscape—not a certification, partnership, or exhaustive product list. Platform selection depends on the customer environment and scope.
NET.01 // NETWORK AUTOMATION
Intent in. Evidence out.
A bounded change moves from observed state to an approved, validated outcome. Human authority and rollback readiness stay visible throughout.
SIMULATION ONLY // NO LIVE SYSTEM CONNECTION
Observe before deciding.
Read inventory and current state so the workflow understands device role, platform, and approved management scope.

campus-a / switch edge-b / branch router fabric-c / leaf switch mode / read-only discovery
Read-only discovery complete.
NET.01 // DELIVERY APPROACH
Defined intent. Controlled change. Verified outcome.
Architecture decisions remain traceable through implementation and operations. Each phase produces evidence the next team can use—not only a completed installation.
Establish the baseline.
Inventory the environment, map flows and dependencies, identify constraints, and define the failure conditions that matter.
Design the operating system.
Develop routing, addressing, segmentation, resiliency, management, and migration decisions with clear rationale.
Test assumptions before impact.
Use lab, pilot, or controlled pre-checks to validate convergence, policy, performance, and automation behavior.
Move with rollback readiness.
Execute in bounded phases, retain acceptance evidence, deliver as-built documentation, and transfer operational knowledge.
