 Overview |
|
Corecess 5424 is a powerfulMetro Ethernet
Switch for Triple Play Services that
can create intelligent and advanced IP services at
the metro area network edge as well as at the access
networks. Corecess 5424 product integrates the functions
of legacy edge router and IP service switch into a
single platform.
From the services point of view,
Corecess 5424 can provide secure access and advanced
quality of service (QoS) features for enabling the
delivery of "Triple Play" Services,
which is a new term that has been coined from the
often used term "Multimedia Services". This feature
is aimed at providing priority traffic including dedicated
bandwidth, controlled jitter and latency (required
by some real-time and interactive traffic), and improved
loss characteristics. It also makes sure that providing
priority for one or more flows does not make other
flows fail.
By incorporating these highly integrated
and well-equipped service features into the Corecess
5424 product, it has been possible to make this product
highly fault tolerant and its flexible architecture
has made Corecess 5424 extremely robust so as to integrate
well into traditional SONET, ATM, and POS networks.
Corecess 5424 is the first product
to have come out of the Corecess 5400 family, which
has 12.8 Gbps of Switching Throughput, wire speed
forwarding capability, and fine tuned traffic control
features. Corecess 5424 is delivered in an eight slot
modular type (two for uplink and six for downlink)
and can provide up to 24, 100Mbps ports and 4 Gbps
ports when fully equipped.
Functionally, Corecess 5424 is suitable
for applications which demand any or a combination
of the following -Layer 2 aggregation, IP routing,
Layer 3 forwarding, rate-limiting, traffic engineering,
and QoS marking and classification. Corecess 5424
can be used for the following applications.
Metro Ethernet service aggregation in a relatively
large customer site.
Metro Ethernet aggregation in a small and medium
sized Central Office (CO).
Interworking of Ethernet, ATM and EoS on a single
platform.
Corecess 5424 provides various functionalities
for next generation IP services. It finds its application
in both edge and access nodes depending on the nature
of applications and network architecture. Corecess
5424 is highly useful, especially for metro Ethernet
service providers. There are many types of subscriber
cards including 100Mbps-FX, Single Fiber. In addition
to this, since service providers have the option to
increase subscriber base by units of 4, initial CapEx
is very low. Considering stability and redundancy,
Corecess 5424 is designed to support two power units
and FANs. The redundant power supply unit and FAN
are replaced on the fly.
For metro Ethernet applications,
Corecess 5424 can be promoted as a solution to the
Corecess 9500 series (gigabit aggregation switch)
and the Corecess 5600 Layer 3 switch to provide a
comprehensive solution governing the region from the
edge to the customer premise.
