TCP/IP provides end-to-end rules for packetizing, addressing, transmitting, routing, and receiving data across networks.
The Internet protocol suite (TCP/IP) is a framework for organizing the communication protocols used on the Internet and similar networks by functional scope. Its purpose is to enable end-to-end data communication by defining how data is packetized, addressed, transmitted, routed, and received. The suite’s foundational protocols are IP (Internet Protocol) along with TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). The suite is structured into four abstraction layers: the link layer, internet layer, transport layer, and application layer. Together, these layers form a protocol stack for a given application, where each layer provides services to the layer above it. The scope of the suite includes both the core protocols and related support standards, with technical specifications maintained by the IETF (Internet Engineering Task Force). Key architectural principles include end-to-end communication, encapsulation across layers, and robustness in how implementations send and accept data.
TCP/IP provides end-to-end rules for packetizing, addressing, transmitting, routing, and receiving data across networks.
The suite is organized into four layers (link, internet, transport, application), and an application’s implementation uses these layers as a protocol stack.
IETF maintains the standards for TCP/IP, including the defining RFCs that describe the layered abstraction and support protocols.
A framework that organizes networking protocols for Internet communication by functional scope and layered abstraction.
The core protocol that provides internetworking by exchanging datagrams across network boundaries.
A transport protocol that provides reliable, connection-oriented data delivery with flow control and connection establishment.
A transport protocol that provides an unreliable, connectionless datagram service.
The process of wrapping data with protocol-specific information as it moves down the layers, enabling abstraction and interoperability.
An architectural idea that places most intelligence and state at the network edges (end hosts) rather than inside the network core.
The organization responsible for maintaining technical standards and specifications for the Internet protocol suite.
