Due to the ever-increasing deployment of the IP (which is connectionless), it is becoming more difficult to find real-world examples of connection-oriented Network layer protocols. 25, which is a WAN-oriented Network layer protocol that emerged in the late 1970s that happens to be an example of a Network layer protocol that is connection-oriented and supports reliable delivery. In addition to addressing information, the header of a Network-layer protocol will include some way to indicate the proper higher-layer client protocol.

The presence of a "Type" field in the original Ethernet header is the main thing that distinguishes it from the protocols that were subsequently developed by the IEEE LMSC, since all of those subsequent protocols rely on the LLC sub-layer protocol (and possibly the SNAP sub-layer protocol) to identify the contents of the frame. [ Team LiB ] [ Team LiB ] 40 41 IEEE LAN Standards The job of developing LAN standards, which are occupants of the Data Link layer, was assumed by the IEEE Project 802 LAN/MAN Standards Committee (LMSC), which has developed a number of LAN standards, including those based on bus topologies and ring topologies.

Who knows, some future virtual telepresence technology may require presently unimaginable amounts of bandwidth. 11's MAC Sub-layer Frame Structure Besides defining access control and resource sharing capabilities for multiple stations contending for a common LAN medium, one of the other key operations performed by the Data Link layer is known as "framing," which is the process of encapsulating the higher-layer protocol packet (which may or may not be a Network layer protocol packet) in a set of Data Link layer headers, and appending a Data Link layer trailer, which is often simply an error-detecting sequence.
