Flexible Bandwidth using GFP and VCAT
For IP packet transport, the V-Node supports to
establish transparent paths between Ethernet. For
efficient and reliable Ethernet transport, Generic
Framing Procedure (GFP) and VC-n-Xv Virtual
Concatenation (VCAT) are adopted.
The GFP adaptation encapsulates Ethernet MAC
frames for subsequent transport over SDH
networks. The VCAT enables the GFP adaptation
to establish flexible bandwidth path.
„
LCAS
The LCAS provides a control scheme to hitless
increase or decrease the bandwidth of a VCAT
Group link to meet the bandwidth needs of the
application.
In addition, the LCAS automatically decrease the
bandwidth if a VCAT member experiences a failure
in the network, and increase the bandwidth when
the network failure is repaired.
„
Various service support
The V-Node provides various interface packages,
such as Gigabit Ethernet, Fast Ethernet, STM-16,
STM-4, STM-1, 45M, 34M and, 2M. The V-Node
main shelf has 13 interface package slots.
„
Bandwidth upgrade up to STM-16
For future traffic growth, the V-Node can be
economically upgraded to dual 2-Fiber STM-16
ring system by just replacing optical interfaces.
„
152x152 VC-4 and 2016x2016 VC-12 matrix for
flexible service support
The matrix of the V-Node has flexible granularity of
152x152 VC-4 and 2016x2016 VC-12.
This
composite matrix enables VC-12 traffic grooming
among VC-4 containers.
„
Integrated management with NEC’s other SDH
and SpectralWave DWDM systems
The INC-100MS offers total management of the
NEC’s photonic transport network composed of the
SpectralWave C-Node, U-Node, the SpectralWave
DWDM systems and the other SMS series SDH
products.
„
Point to Point/Multipoint Ethernet Service
The V-Node can establish Ethernet Line (E-Line)
service type of point-to-point paths. The bandwidth
assignment itself is flexible and can be hitless
changed by using VCAT and LCAS methods.
The E-Line service is a best effort type of
connection service using L2SW sharing the
bandwidth of VCAT paths among plural
connections. Security among the connections is
guaranteed by VLAN method.
The E-Line type of connection service using L2SW
can be easily expanded to Ethernet LAN (E-LAN)
service type of multipoint-to-multipoint connections.
Security among the connections is guaranteed by
VLAN method.
