A Packet Switch (PS) Core Engineer is a professional who specializes in the design, development, and maintenance of packet-switched networks. These engineers work on the core infrastructure of a network, which includes routers, switches, and other networking equipment that are responsible for routing data packets between different nodes or devices in the network.
The job of a Packet Switch Core Engineer typically involves tasks such as network architecture design, network optimization, troubleshooting network problems, and developing new networking technologies. They must have a deep understanding of networking protocols and technologies, including TCP/IP, routing protocols such as OSPF and BGP, and network security protocols.
