A data center is a pool of resources (computational, storage, network) interconnected using a communication network. [1][2] A data center network (DCN) holds a pivotal role in a data center, as it interconnects all of the data center resources together. DCNs need to be scalable and efficient to connect tens or even hundreds of thousands of ...
Software-defined networking (SDN) is an approach to network management that enables dynamic and programmatically efficient network configuration to improve network performance and monitoring in a manner more akin to cloud computing than to traditional network management. [1] SDN is meant to improve the static architecture of traditional ...
A computer network diagram of clients communicating with a server via the Internet. The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. [ 1 ] Often clients and servers communicate over a ...
Hierarchical internetworking model. The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco in 1998. [1] The hierarchical design model divides enterprise networks into three layers: core, distribution, and access.
Service-oriented architecture integrates distributed, separately maintained and deployed software components. It is enabled by technologies and standards that facilitate components' communication and cooperation over a network, especially over an IP network. SOA is related to the idea of an API (application programming interface), an interface ...
A complement to IT application-level security and data-level security solutions, and a sub-set of Network management, Network assurance measures the impact of network change on security, availability, and compliance. Network assurance helps companies keep policies and defences correctly implemented during times of rapid network change.
SONiC (operating system) The Software for Open Networking in the Cloud or alternatively abbreviated and stylized as SONiC, is a free and open source network operating system based on Linux. It was originally developed by Microsoft and the Open Compute Project. In 2022, Microsoft ceded oversight of the project to the Linux Foundation, who will ...
A secure access service edge (SASE) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection (user, device, Internet of things (IoT) device, or edge computing location) rather than a data center. [1] It uses cloud and edge computing technologies to reduce the ...
