The disadvantages of using SONET/ SDH in the metro include: * Fixed circuits. SONET/SDH provisions point-to-point circuits between ring nodes. Each circuit is allocated a fixed amount of bandwidth that is wasted when not used. That fixed allocation puts a limit on the maximum burst traffic data transfer rate between end points. This is a disadvantage for data traffic, which is inherently bursty. * Waste of bandwidth for meshing. Provisioning the circuits necessary to create a logical mesh over a SONET ring is not only difficult, but also results in an inefficient use of ring bandwidth. As the amount of data traffic that stays within metro networks is increasing, a fully meshed network that is easy to deploy, maintain and upgrade is becoming an important requirement. * Multieast traffic. On a SONET/SDH ring, multicast traffic requires each source to allocate a separate circuit for each destination. A separate copy of the packet is sent to each destination. The result is multiple copies of multicast packets traveling around the ring, wasting bandwidth.
Sonet Film was created in 1984.
Ishraq Sonet was born in 1987.
SDH = 3 times of SONET
Yes, Ethernet can be transported over SONET (Synchronous Optical Network) using a method called "Ethernet over SONET" (EoS). This technique encapsulates Ethernet frames within SONET frames, allowing Ethernet data to be transmitted over SONET links while taking advantage of SONET's high-speed, reliable transmission capabilities. EoS facilitates the integration of Ethernet services into existing SONET networks, enabling service providers to offer Ethernet services over long distances.
SONET
SONET uses an inverse multiplexing technique called virtual concatenation. SONET, which is the standard used in the United States and most of Europe, stands for Synchronous Optical Network.

A SONET is a type of network technology layer that is physical. It is used for transporting a lot of traffic over fiber optic cabling.
(True) SONET Specifies framing and multicomplexing at the physical layer of the OSI model.
Synchronous Optical Networks (SONET) have various optical networks. An OC-3 circuit is one of these. The answer is yes, since OC-3 is a product of the SONET architecture.
