  2. Synchronous optical networking - Wikipedia

    en.wikipedia.org/wiki/Synchronous_optical_networking

    SONET/SDH is not a complete communications protocol in itself, but a transport protocol (not a "transport" in the OSI Model sense). Due to SONET/SDH's essential protocol neutrality and transport-oriented features, SONET/SDH was the choice for transporting the fixed length Asynchronous Transfer Mode (ATM) frames also known as cells. It quickly ...

  3. G.709 - Wikipedia

    en.wikipedia.org/wiki/G.709

    The G.709 OTUk signal is positioned as a server layer signal for various client signals, e.g. SDH/SONET, ATM, IP, Ethernet, Fibre Channel and OTN ODUk (where k=0, 1, 2, 2e, 3, 3e2, 4 or flex). [3] Work on support for InfiniBand and Common Public Radio Interface client signals is currently [ when? ] in progress.

  4. Ethernet over PDH over SONET/SDH (EoPoS) is one of many techniques that provided Ethernet connectivity over non-Ethernet networks. EoPoS is a standardized method for transporting native Ethernet frames over the existing telecommunications optical infrastructure use both the established Plesiochronous Digital Hierarchy (PDH) and Synchronous Digital Hierarchy (SONET/SDH) transport technologies.

  5. Ethernet over SDH - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_SDH

    After traversing SDH paths, the traffic is processed in the reverse fashion: virtual concatenation path processing to recreate the original synchronous byte stream, followed by decapsulation to converting the synchronous data stream to an asynchronous stream of Ethernet frames. The SDH paths may be VC-4, VC-3, VC-12 or VC-11 paths.

  6. Packet over SONET/SDH - Wikipedia

    en.wikipedia.org/wiki/Packet_over_SONET/SDH

    Packet over SONET/SDH, abbreviated POS, is a communications protocol for transmitting packets in the form of the Point to Point Protocol (PPP) over SDH or SONET, which are both standard protocols for communicating digital information using lasers or light emitting diodes (LEDs) over optical fibre at high line rates. POS is defined by RFC 2615 ...

  7. Virtual concatenation - Wikipedia

    en.wikipedia.org/wiki/Virtual_concatenation

    Sonet/SDH is a hierarchical network. At each level, payloads are a concatenation of lower-order payloads. So, for example, an STS192 (10 Gbit/s) payload consists of four OC48 (2.5 Gbit/s) payloads concatenated together.
