Network Architecture

Modern networks must provide reliable connectivity across offices, data centers, cloud environments, remote users, and third-party services.

TJs Network & Security helps organizations design and modernize network infrastructure that is resilient, secure, scalable, and operationally supportable.

Routing and SD-WAN

We assist with environments that require more than basic static routing.

Areas of experience include:

  • BGP
  • OSPF
  • Route reflection
  • Route maps and policy control
  • Prefix filtering
  • Path selection
  • Redundant internet connectivity
  • Multi-hub SD-WAN
  • ADVPN
  • Application-aware routing
  • Underlay and overlay monitoring
  • Asymmetric-routing analysis
  • Cloud route integration

Network Modernization

A modernization engagement may include:

  • Reviewing the existing environment
  • Identifying technical debt and operational risk
  • Developing a target architecture
  • Creating migration phases
  • Validating hardware and licensing requirements
  • Building implementation templates
  • Documenting rollback procedures
  • Assisting with deployment and testing

Common Network Engagements

  • Redesigning a network that has grown without consistent standards
  • Consolidating several routing and switching platforms
  • Improving branch resiliency
  • Migrating to SD-WAN
  • Troubleshooting intermittent packet loss or asymmetric routing
  • Designing a new data center or cloud connection
  • Reviewing a proposed architecture before purchase or deployment
  • Creating repeatable standards for future locations
