The System Packet Interface (SPI) family of Interoperability Agreements from the Optical Internetworking Forum specify chip-to-chip, channelized, packet interfaces commonly used in synchronous optical networking and Ethernet applications. A typical application of such a packet level interface is between a framer (for optical network) or a MAC ...
Throughout the 2000s, the OIF produced an important series of interfaces that influenced the development of multiple generations of devices. Beginning with the donation of the PL-3 interface by PMC-Sierra in 2000, the OIF produced the System Packet Interface (SPI) family of packet interfaces.
SPI-4.2 is a version of the System Packet Interface published by the Optical Internetworking Forum.It was designed to be used in systems that support OC-192 SONET interfaces and is sometimes used in 10 Gigabit Ethernet based systems.
A Queued Serial Peripheral Interface (QSPI; different to but has same abbreviation as Quad SPI described in § Quad SPI) is a type of SPI controller that uses a data queue to transfer data across an SPI bus. [19]
System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard.. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple ...
Beginning with the donation of the PL-3 interface by PMC-Sierra in 2000, the OIF produced the System Packet Interface (SPI) family of packet interfaces. SPI-3 and SPI-4.2 defined two generations of devices before they were supplanted by the closely related Interlaken standard in the SPI-5 generation in 2006.
The System Packet Interface series of standards from the Optical Internetworking Forum including SPI-4.2 and SPI-3 and their predecessors PL-4 and PL-3 are commonly used as the interface between packet processing devices and framer devices that implement POS. The acronym PL-4 means POS-PHY Layer 4.
