what are two functions supported by a data link layer protocol?
242693
The three main functions of the data link layer are to deal with transmission errors, regulate the flow of data, and provide a well-defined interface to the network layer.

Protocols in the data link layer are designed so that this layer can perform its basic functions: framing, error control and flow control. Framing is the process of dividing bit - streams from physical layer into data frames whose size ranges from a few hundred to a few thousand bytes.

Layer 3 provides switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node. Routing and forwarding are functions of this layer, as well as addressing, internetworking, error handling, congestion control and packet sequencing.

Protocol data units of the OSI model are: The Layer 4: transport layer PDU is the segment or the datagram. The Layer 3: network layer PDU is the packet. The Layer 2: data link layer PDU is the frame.

other services and applications: WAP layered architecture enables other services and applications using the WAP good interface protocol stack through a set of function definitions. External applications can directly access the protocol stack in the session layer, transaction layer, security and transport layers.

Remote Function Call (RFC) is the standard SAP interface for communication between SAP systems. RFC calls a function to be executed in a remote system. There is now a whole series of different RFC variants, each of which has different properties and is used for a specific purpose. Synchronous RFC.

Explanation: The Logical Link Control (LLC) defines the software processes that provide services to the network layer protocols. ... This information allows multiple Layer 3 protocols, such as IPv4 and IPv6, to utilize the same network interface and media.

The User Datagram Protocol (UDP) is a very thin protocol build on top of the Internet Protocol. The basic unit of data is a User datagram and the UDP protocol provides the same unreliable, connectionless service transferring user datagrams as the IP protocol does transferring its datagrams.

Network Security The MAC sublayer controls device interaction. The LLC sublayer deals with addressing and multiplexing. Physical addressing for network connections exists at the data link layer. The data link layer combines data bits into entities called frames.

The data link layer is responsible for framing data bits, providing the physical addresses of the sender/receiver, data rate control and detection and correction of damaged and lost frames. ... Routers operate at this layer—sending data throughout the extended network and making the Internet possible.

The "a=fmtp:" attribute in the answer specifies 101 as payload type number instead of 120. That means it doesn't apply to the telephone-events payload and no information is available as to which DTMF events are supported (RFC 4733). ... It is an indication that you should expect DTMF issues.

UDP (User Datagram Protocol) is a communications protocol that is primarily used for establishing low-latency and loss-tolerating connections between applications on the internet.
