As a network specialist I worked with the Network Competency Center team at the Boston One Campus. Our role was to perform system design and validation of complex system prototypes for selected customers which included VPN, routing, firewalls, QoS, network management, IDS, IPS, redundancy and other technologies. In addition, we performed system level validation of new products to ensure they were suitable for use in the preferred architectures and we developed complex test and validation plans.
