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 ...
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.
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 ...
The OTN signals at all data-rates have the same frame structure but the frame period reduces as the data-rate increases. As a result, the Time-Slot Interchange (TSI) technique of implementing SONET/SDH switch fabrics is not directly applicable to OTN switch fabrics. OTN switch fabrics are typically implemented using Packet Switch Fabrics.
In honor of Cow Appreciation Day, they shared 5 different ways that cows show they are happy, and it'll warm your heart! The first one they share is that if a cow trusts you completely, they'll ...
Deer Greek: Also called Cerynitis, was an enormous deer that lived in Keryneia, Greece. It was sacred to Artemis, the chaste goddess of the hunt, animals and unmarried women. It had golden antlers like a stag and hooves of bronze or brass, and it was said that it could outrun an arrow in flight.
The yellow dot is the origin of the family Camelidae and the black arrows are the historic migration routes that explain the present-day distribution. Camelids are unusual in that their modern distribution is almost the inverse of their area of origin.
Here is every type of economic system out there explained with cows: Posted by Mike Hosking. Cows are being used for way more than making milk. From protests like the one above, all the way to ...
