The new layer-2 configuration protocols work with backward-compatible extensions to the Ethernet 802.1 frame format; such minimal changes allow AVB devices to coexist and communicate in standard IT networks, however, only AVB-capable switches and endpoint can reserve network resources with admission control and synchronize local time to a ...
SSL Secure Socket Tunneling [2] AFP Apple Filing Protocol [2] Independent Computing Architecture , the Citrix system core protocol; Lightweight Presentation Protocol (LPP) [2] NetWare Core Protocol (NCP) Network Data Representation (NDR) [2] Tox, The Tox protocol is sometimes regarded as part of both the presentation and application layer
The NPL network, or NPL Data Communications Network, was a local area computer network operated by a team from the National Physical Laboratory (NPL) in London that pioneered the concept of packet switching. Based on designs first conceived by Donald Davies in 1965, development work began in 1966. Construction began in 1968 and elements of the ...
Connection-oriented Presentation protocol – ITU-T Rec. X.226 [ISO/IEC 8823-1] Connectionless Presentation protocol – ITU-T Rec. X.236 [ISO/IEC 9576-1] This layer defines and encrypts/decrypts data types from the application layer. Protocols such as MIDI, MPEG, and GIF are presentation layer formats shared by different applications.

While Generic Routing Encapsulation (GRE) might seem to be a network-layer protocol, if the encapsulation of the payload takes place only at the endpoint, GRE becomes closer to a transport protocol that uses IP headers but contains complete Layer 2 frames or Layer 3 packets to deliver to the endpoint. L2TP carries PPP frames inside transport ...
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
This defines protocols and practices for the operations, administration, and maintenance (OAM) of paths through 802.1 bridges and local area networks (LANs). The final version was approved by the IEEE in 2007. [1] IEEE 802.1ag is a subset of the earlier ITU-T Recommendation Y.1731, which additionally addresses performance monitoring. [2] The ...
