Network Infrastructure

Properly designed, implemented and maintained networking is essential for reliability of the services you need to access, as well as the ones you provide.

Network Design

Network design includes a set of planning decisions about aspects of your organization’s connectivity, including:

Active equipment

Routers and switches are the critical active components that ensure fast and reliable traffic flow within your network. I use different approaches, based on the size of the network (number of active devices) – ranging from SOHO routers and switches up to dedicated routers (usually FreeBSD-powered servers or specialized devices) and managed switches, providing quality of service, link aggregation, jumbo frames, spanning tree, etc.


Network security is a complex and constantly changing discipline, requiring very specialized knowledge and constant updates in order to keep the network safe.

I employ stateful firewalls and intrusion detection systems to keep intruders out. I use VLANs to segregate the network internally. Access to internal resources from outside is enabled through VPN.

Structured Cabling Systems

Structured cabling systems allow protection and longevity of the passive components – cables (copper and/or fiber), patch panels and racks (communication and/or equipment). Importance of proper structured cabling, cable management, labeling and documentation increases exponentially with the size of the network.

I design and implement network topologies, specify, procure and install active equipment, design and implement security, design implement and maintain structured cabling systems.
