Operations Consultant

  • Auditing a network of 50,000+ websites for resource usage using SNMP-capable open-source network management systems monitoring Cisco 2950 series switches
  • Providing customers with layer 2 quality of service (QoS) features such as link failure detection, transmission error accounting, and broadcast suppression via SNMP
  • Providing customers with layer 3 QoS features such as gateway redundancy via HSRP and load sharing via multiple OSPF routing paths
  • Implementing a seamless migration from a non-redundant core network to a fully redundant, auto-switching core consisting of SONET and DS-3 circuits
  • Maintaining a core network of Juniper M5 and M7i routers, providing Internet services such as load balancing and asynchronous routing via BGP
  • Maintaining an access network of layer 2/3 Cisco 4000 switches, providing LAN services such as gateway redundancy and layer 2 STP loop prevention
  • Detailing network traffic profiles to aid in detecting intrusions, denial of service (DoS) attempts, and customer network abuse
  • Researching and beta testing new technologies for network devices, such as the Juniper Networks Adaptive Services module providing stateful firewall packet inspection, intrusion detection (IDS), and flow accounting
  • Stress-testing current and proposed router and switch software for stability, performance, and security
  • Integrating Cisco 7206 VXR routers to handle the layer 3 routing and gateway functions, enabling the Cisco 4000 switches to focus on layer 2 functions
  • Projecting future bandwidth, electrical power, and equipment needs for the next 18-24 months based on initial and updated data analysis
  • Training staff to build server and telco racks, manage cable, conduit and distribution runs, and implement easy-to-follow labeling schemes
  • Training staff on network design concepts such as routing, switching, and performance tuning
  • Designing a complete, integrated network management platform comprised of open-source software for automating alerts, failure detection, trouble-ticket creation, failure correlation, and network overviews
  • Creating a centralized login cluster to provide simple user creation and authorization for all servers via OpenLDAP, allowing authorized login to selected systems using the same username and password pairs
  • Streamlining the purchasing process to provide faster ordering of equipment, lower purchasing costs, and more intelligent equipment purchases
  • Managing IP allocation, network security and documentation policies
  • Utilizing Visio 2003 to produce network diagrams detailing current network topologies, maintenance, and future integrations
  • Managing personnel issues such as vendor relationships, customer communications, and team building
