The TCP/IP Model separates networking functions into discrete layers. Each layer performs a specific function and is transparent to the layer above it and the layer below it. Network models are used to conceptualize how networks should work, so that hardware and network protocols can interoperate. There are two main models: TCP/IP Model and OSIContinue reading “TCP/IP MODEL”

Google Cloud Platform (GCP)

What is Google Cloud Platform (GCP)? Google Cloud Platform (GCP) has one of the largest and fastest networks in the world. GCP resources are treated as services instead of hardware. For example, Persistent Disk is not a physical device, but is a service used over a network.   Projects, Networks, and Subnetworks All infrastructure resources in GCP are organized underContinue reading “Google Cloud Platform (GCP)”

Software-Defined Networking (SDN)

Key Areas in SDN SDN focuses on the following key areas: Separation of data plane from the control plane. Centralization of the control plane. Standardized interfaces between the device and controller. Programmability of control plane by external applications.   Separating Data Plane from Control Plane SDN allows the user to treat all the devices equallyContinue reading “Software-Defined Networking (SDN)”
