Computer Network IT Support Chatswood Sydney

TCG TECH designs, plans & architects new & existing networks including configuring & installing:

  • Switches & Routers
  • Firewalls
  • Load Balancers
  • Storage Area Network (SAN)
  • Wireless
  • DNS...

​Our technicians also have diagnostic tools to diagnose & remediate problems to optimize the performance of your network. Our engineers diagnose problems such as increased network load, bandwidth-hogging users, bandwidth utilization, packet loss, congestion...or implementing failover architecture to avoid downtime - all part of our services.

Network Design & IT Planning

General principles/guidelines we have developed when designing/maintaining a network:

  • Our networks are designed to have 100% up time even in the event of failed links, equipment failure...

  • They reliably deliver applications & provide reasonable response times.

  • Our network design includes security provisions-protecting data transmitted & stored on devices.

  • Our designs are not over-complicated - they are easy to modify for network growth & business changes.

  • And troubleshooting failures are prompt & easy with our network documentation.

Fundamental Design Goals

When examined carefully, these requirements translate into four fundamental network design goals:

  • Scalability:  We build scalable network designs that grow to include new user groups, remote sites, new applications...without impacting the level of service delivered to existing users.

  • Availability:  Our network designs delivers consistent, reliable performance, 24/7/365.  The failure of a single link or piece of equipment will not significantly impact network performance because we build redundant systems into the network.

  • Security:  Security is planned & designed into the network from the start.  It includes planning the location of security devices, filters, and firewall features critical to safeguarding network resources.

  • Manageability:  We provide an industry-standard design that any experienced network administrator can manage and support.  A network design that is too complex or difficult to maintain cannot function effectively and efficiently.

Network Performance Monitoring

When it comes to in-depth open source network monitoring tools, our engineers custom-configure a Nagios & Cacti solution.  Nagios monitors networks for problems caused by overloaded data links or network connections, as well as monitoring routers, switches and more.  Nagios also monitors availability, uptime and response time of every node on the network.

We also utilize Nagios/Cacti to monitor virtual servers - a pre-warning system in case of downtime - to avoid the monthly fees associated with monitoring servers versus a one-time configuration fee.  Nagios can deliver the results in a variety of visual representations and reports.
