Disadvantages of sonet?
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.
What is a collapsed sonet ring?
A collapsed sonet ring refers to a ring architecture where the physical fibers used for working and protect both reside in the same physical bundle or buffer tube. The result of this is that typically in the event of a fiber cut, the entire ring will be taken down.
What wan topologies that are good choices for highly available enterprise networks?
sonet ring
SONET uses which topology?
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
What is SONET's results from its use of a double-ring topology over fiber -optic cable?
fault tolerance
What is the minimum optical carrier level that the sonet ring must have to support the bandwidth of the t3?
Network+ Guide to Networks answer: OC1

What part of a sonet network allows it to be self healing?
A. Its double-ring topology.... try using the book now and again :D on pg325 Network+ 5th :P And for those of us confused and lost, thank you
The data rate of a particular SONET ring is indicated by its OC a rating that is internationally recognized by networking professionals and standards organizations?
OC (Optical Carrier) level.
What is a homograph sentence with the word ring?
Sure! Here is a homograph sentence with the word "ring": "He proposed with a diamond ring while watching the boxing ring."
What did one telephone say to the other when it proposed?
i will give you a ring
What is Ring Protection in SDH?
Ring protection is a system where multiplexers are connected in a ring topology. If a single span fails traffic switches around the other side of the ring.
