Classification, Requirements and User's Guide
DESCRIPTION
The T4000 supports 4 Tbps in a single chassis and is
multichassis capable. This future-proofed architecture
scales comfortably as provider needs progress.
There is no single point of failure in T Series routers.
Component-level redundancy is available for Routing
Engines, CBs, and SIBs, as well as PEMs and the internal
control plane.
T4000 supports continuous operation under
maintenance conditions, and topological changes by
means of nonstop active routing (NSR) and unified in-
service software upgrade (unified ISSU).
The T4000 programmable ASICs family delivers
a comprehensive, hardware-based system for rich
processing.
Interfaces on the T Series range from DS3 to OC-
768 (SONET) and 100GbE for Ethernet. The T4000
provides the largest variety of interfaces in the densest
form factor among core routing platforms.
BENEFIT
T4000 scale and density features allow service
providers to increase capacity without adding additional
systems to the network.
HA and continuous operation is critical in core routing,
where loss of a single routing node can remove service
for a wide geographical area.
HA requirements in core networks include the
elimination of planned downtime, giving the benefit
of better network stability, easier operations, and less
operational risk.
Features such as highly granular QoS, advanced filter-
based forwarding, and flow-based monitoring are a key
component for providing wide ranging services on a
single network.
Combining the functions of previously disparate
network elements offers greater network simplicity, and
retains the service building advantages of the overlay
networks being replaced by the converged network.
