This is not an exhaustive list, as there are numerous protocols in each layer and variations within each protocol. Additionally, some protocols may operate across multiple layers, such as IP which operates at the Network Layer but is encapsulated within Ethernet frames at the Data Link Layer. The list provided includes some of the widely used and well-known protocols in each layer of the network protocol stack.

Which Protocols operate across multiple layers?

List of protocols that operate across multiple layers of the network protocol stack:

1. TCP/IP (Transmission Control Protocol/Internet Protocol):

TCP operates at the Transport Layer, providing reliable, connection-oriented data delivery.
IP operates at the Network Layer, responsible for addressing, routing, and fragmenting/reassembling packets.

UDP/IP (User Datagram Protocol/Internet Protocol):

UDP operates at the Transport Layer, providing connectionless, unreliable data delivery.
IP operates at the Network Layer, handling addressing, routing, and packet fragmentation/reassembly.

Ethernet:

Ethernet operates at the Data Link Layer, providing a frame-based mechanism for data transmission.
It uses MAC (Media Access Control) addresses to identify devices at the Data Link Layer.

IPv6 over Ethernet:

IPv6 (Internet Protocol version 6) operates at the Network Layer, handling addressing, routing, and packet fragmentation/reassembly.
Ethernet operates at the Data Link Layer, providing the frame structure and physical transmission.

PPP (Point-to-Point Protocol):

PPP operates at the Data Link Layer, encapsulating multiple network layer protocols for transmission.
It is commonly used for establishing point-to-point connections over various physical media, such as serial connections and DSL.

MPLS (Multiprotocol Label Switching):

MPLS operates across the Data Link Layer and Network Layer, using labels to forward packets within a network.
It is often used to provide traffic engineering, quality of service (QoS), and virtual private network (VPN) services.

DNS (Domain Name System):

DNS operates across the Application Layer, Transport Layer (using TCP or UDP), and Network Layer (using IP).
It resolves domain names to IP addresses, enabling the translation between human-readable domain names and machine-readable IP addresses.

TLS/SSL (Transport Layer Security/Secure Sockets Layer):

TLS/SSL operates between the Transport Layer and the Application Layer, providing secure communication channels.
It encrypts data and provides authentication and integrity checks for secure transmission over protocols like HTTP (HTTPS).

These are some examples of protocols that span multiple layers, providing functionality and services across those layers in the network protocol stack.
