* GFP (Generic Framing Procedure) maps higher order protocols
onto SONET. GFP provides rules for payload specific mapping
on various network topologies.
* LCAS, the Link Capacity Adjustment Scheme, allows for
dynamic provisioning of bandwidth using VC. With LCAS,
the network does not need to be shut down and data is
not lost during the re-provisioning of bandwidth.
These new technologies create many new testing challenges.
For example, the diverse routing process inherent in VC
creates "differential delays" -- that is, time
differences between the arrivals of different paths at
the receiving end of the network (see diagram below).
The ramifications of these delays can be significant,
especially on delay sensitive services such as video and
storage.
SONET/SDH Network Delay Emulators help organizations
that are developing and deploying Next Gen SONET solutions.
Anue’s SONET/SDH WAN Emulation products generate two types
of delays: signal delays and path layer delays. A Signal
Delay Emulator is like a programmable spool of fiber,
where delays can be injected in bit level increments up
to 750 ms. The Path Delay Emulators delay individual segments
of data of various sizes within a SONET signal by up to
320 ms of differential delay. With these WAN Emulation
solutions users can simulate the transmission delays and
path jitter that will be encountered by diversely routed
members of a VC group.
Change in network content and competitive pressures have
fueled the need to develop Next Gen SONET technologies
to efficiently deliver new revenue generating services
over existing optical networks. Before deploying these
new technologies, however, it is critical to evaluate
the effects on services using GFP or running through a
VC/LCAS environment. Anue WAN Emulators can help you do
this!
With a scalable, cost-effective solution for many of the
challenges faced by today’s developers of Next Gen SONET
network equipment and systems, Anue Systems is leading
the way in Next Gen SONET testing. Designing, building
and testing next generation SONET products, including
VC/LCAS solutions, require WAN Emulation tools such as
those from Anue Systems with targeted delay emulation
and impairment functionality.
