  2. Network planning and design - Wikipedia

    en.wikipedia.org/wiki/Network_planning_and_design

    Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]

  3. OSI model - Wikipedia

    en.wikipedia.org/wiki/OSI_model

    Cross-layer functions are the norm, in practice, because the availability of a communication service is determined by the interaction between network design and network management protocols. Specific examples of cross-layer functions include the following: Security service (telecommunication) [34] as defined by ITU-T X.800 recommendation.

  4. Hierarchical internetworking model - Wikipedia

    en.wikipedia.org/wiki/Hierarchical...

    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.

  5. Network architecture - Wikipedia

    en.wikipedia.org/wiki/Network_architecture

    The Open Systems Interconnection model (OSI model) defines and codifies the concept of layered network architecture. Abstraction layers are used to subdivide a communications system further into smaller manageable parts. A layer is a collection of similar functions that provide services to the layer above it and receives services from the layer ...

  6. Hierarchical network model - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_network_model

    The hierarchical network model is part of the scale-free model family sharing their main property of having proportionally more hubs among the nodes than by random generation; however, it significantly differs from the other similar models (Barabási–Albert, Watts–Strogatz) in the distribution of the nodes' clustering coefficients: as other models would predict a constant clustering ...

  7. Software-defined networking - Wikipedia

    en.wikipedia.org/wiki/Software-defined_networking

    Software-defined mobile networking (SDMN) [51] [52] is an approach to the design of mobile networks where all protocol-specific features are implemented in software, maximizing the use of generic and commodity hardware and software in both the core network and radio access network. [53]

  8. Complex network - Wikipedia

    en.wikipedia.org/wiki/Complex_network

    Ideas and tools from network science and engineering have been applied to the analysis of metabolic and genetic regulatory networks; the study of ecosystem stability and robustness; [11] clinical science; [12] the modeling and design of scalable communication networks such as the generation and visualization of complex wireless networks; [13 ...

  9. Network layer - Wikipedia

    en.wikipedia.org/wiki/Network_layer

    The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI (Open Systems Interconnection) network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.
