  2. 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.

  3. 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 ...

  4. Virtual concatenation - Wikipedia

    en.wikipedia.org/wiki/Virtual_concatenation

    In conjunction with LCAS and GFP, Virtual Concatenation gives the advantage of splitting the required bandwidth equally among a set number of sub paths called Virtual Tributaries (VT). The Virtual Concatenation is specified in ITU-T Recommendations G.707 (2007) [ 1 ] and G.783 (2006).

  5. Subnetwork connection protection - Wikipedia

    en.wikipedia.org/wiki/Subnetwork_Connection...

    In telecommunications, subnetwork connection protection (SNCP), is a type of protection mechanism associated with synchronous optical networks such as synchronous digital hierarchy (SDH). SNCP is a dedicated (1+1) protection mechanism for SDH network spans which may be deployed in ring, point to point or mesh topologies .

  6. Ethernet over PDH - Wikipedia

    en.wikipedia.org/wiki/Ethernet_over_PDH

    EoPDH is a standardized methodology for transporting native Ethernet frames over PDH links such as T1, E1, or DS3.The technologies used in EoPDH include GFP frame encapsulation, Ethernet Mapping, Virtual Concatenation, Link Capacity Adjustment Scheme, and Management Messaging (OAM Archived 2006-08-23 at the Wayback Machine).

    Prospect Point at the Niagara Reservation, c. 1900.The reservation, known today as Niagara Falls State Park, was the first park opened by New York State.. State-level procurement and management of parks in New York began in 1883, when then-governor Grover Cleveland signed legislation authorizing the appropriation of lands near Niagara Falls for a "state reservation".
