LAN / VLAN / ROUTING / DESIGN

Network Infrastructure

Design and implement enterprise networks from IP and VLAN planning to switching, routing, and branch connectivity, with a topology that is documented and practical to troubleshoot.

LAN design

Topology for the real site

Segmentation

Clear VLAN and subnet plan

Connectivity

Switching and routing

Documentation and diagnosis

NETWORK DESIGN

A network whose paths are understandable and extensible

An enterprise network is more than a set of switches. User and server locations, VLAN and subnet design, traffic paths, port capacity, and future growth need to fit one coherent map so changes and troubleshooting remain traceable.

SERVICE CAPABILITIES

What Network Infrastructure covers

Design and implement enterprise networks from IP and VLAN planning to switching, routing, and branch connectivity, with a topology that is documented and practical to troubleshoot.

Design and addressing

  • Network topology

    Align site, equipment, and aggregation points with organizational needs.

  • IP and subnet plan

    Plan addressing and subnets around services and expected growth.

  • VLAN design

    Define logical boundaries for users, servers, and connected equipment.

Switching and routing

  • Access and distribution

    Review layer roles and connection capacity across offices and branches.

  • Internal routing

    Document traffic paths between subnets and internal services.

  • Branch connectivity

    Assess site connectivity needs against available paths.

Performance and documentation

  • Connectivity troubleshooting

    Investigate ports, VLANs, addressing, routes, and performance symptoms.

  • Capacity planning

    Record port and uplink use alongside expected expansion.

  • Topology documentation

    Hand over a network map and key settings for operations.

NETWORK TOPOLOGY

Trace users to services and their network paths

A topology should represent real traffic paths and dependencies, not just decorative equipment placement.

OPERATIONAL OUTCOMES

A network that is easier to operate

  • Clear paths

    VLANs, subnets, and connection points are mapped.

  • Controlled changes

    New sites and services follow a documented structure.

  • Focused troubleshooting

    The checks from access layer through routing are clear.

COMMON ENVIRONMENTS

Network challenges this service addresses

New or redesigned network

Plan a LAN around buildings and teams.

New VLAN or subnet

Add maintainable logical segmentation and addressing.

Branch connectivity

Review requirements and paths between locations.

Intermittent or slow access

Trace ports, uplinks, routing, and traffic paths.

DELIVERY APPROACH

From current-state discovery to an implementation map

  1. 01

    Discover

    Record equipment, sites, services, and current connections.

  2. 02

    Define needs

    Clarify capacity, logical boundaries, and required paths.

  3. 03

    Design

    Prepare topology, IP plan, and VLAN layout.

  4. 04

    Implement

    Apply agreed changes in stages and validate connectivity.

  5. 05

    Document

    Hand over the map and relevant configuration details.

TECHNOLOGY SCOPE

Concepts and components considered

Implementation is aligned with the organization’s existing equipment; no vendor dependency is assumed.

  • LAN
  • VLAN
  • IPv4 Subnetting
  • Switching
  • Routing
  • Access / Distribution / Core
  • Branch Connectivity
  • Topology Documentation

WHY SYSTECHNIC

Architecture designed for practical operations

Clear service boundary

Connectivity design stays distinct from security control configuration.

Environment-aware

Existing equipment, capabilities, and operator skills inform the design.

Documented output

Decisions and paths remain useful for future changes.

FAQ

Network infrastructure questions

What is included in enterprise network design?

Depending on scope, topology, IP planning, VLANs, switching, routing, branch connectivity, and documentation are reviewed.

Does this page include firewall and VPN work?

No. This page focuses on LAN connectivity and architecture; firewalls, VPNs, and access controls are covered by Network Security.

Can you troubleshoot an existing network?

Yes. Ports, VLANs, subnets, routes, and performance symptoms can be investigated based on available access and information.

Can you design for multiple branches?

Yes. Branch requirements and available paths are considered; implementation depends on existing equipment and connectivity services.

Must equipment come from one vendor?

No. Compatibility and actual device capabilities are assessed against organizational needs and constraints.

What documentation is delivered?

Depending on scope, deliverables may include a topology map, IP/VLAN plan, and agreed key configuration details.
