2. Generic Framing Procedure - Wikipedia

   en.wikipedia.org/wiki/Generic_Framing_Procedure

   GFP utilizes a length/HEC-based frame delineation mechanism that is more robust than that used by High-Level Data Link Control (HDLC), which is single octet flag-based. There are two types of GFP frames: a GFP client frame and a GFP control frame. A GFP client frame can be further classified as either a client data frame or a client management ...

3. Ethernet over SDH - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_SDH

   A 10-Mbit/s Ethernet link is often transported over a VC-12-5v which allows the full bandwidth to be carried for all packet sizes. A 100-Mbit/s Ethernet link is often transported over a VC-3-2v which allows the full bandwidth to be carried when smaller packets are used (< 250 bytes) and Ethernet flow control restricts the rate of traffic for ...

4. 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 ...

5. Ethernet over PDH over SONET/SDH - Wikipedia

   en.wikipedia.org/.../SDH

   EoPoS is a standardized method for transporting native Ethernet frames over a SONET/SDH network, by first mapping into one or more PDH tributaries such as T1, E1, or DS3. The tributaries can then be dropped from a legacy ADM , delivered to the customer premises, and the PDH links resolved back to an Ethernet connection by a piece of equipment ...

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. STM-1 - Wikipedia

   en.wikipedia.org/wiki/STM-1

   The STM-1 (Synchronous Transport Module level-1) is the SDH ITU-T fiber optic network transmission standard. It has a bit rate of 155.52 Mbit/s. It has a bit rate of 155.52 Mbit/s. Higher levels go up by a factor of 4 at a time: the other currently supported levels are STM-4 , STM-16 , STM-64 and STM-256 .
