Resiliency
The Ethernet Routing Switch 1600
provides increased reliability for small
network cores. Dual redundant power
supplies ensure maximum availability of
networking hardware. Support for Split
Multi-Link Trunking (SMLT) and Link
Aggregation (802.3ad static compliant)
provides redundant load sharing
connections to one or more desktop
switches. Resiliency is addressed at
multiple layers ensuring the highest
availability of resources and the lowest
network downtime.

Split Multi-Link Trunking
(SMLT) and Link Aggregation
Link Aggregation support allows up to
four ports to be grouped as a single
trunk, providing increased bandwidth
and resilient connections. Combined
with Nortel’s unique SMLT technology,
switches can be dual homed or have
multiple active connections to a network
core. By utilizing these dual connections
and bypassing traditional solutions like
Spanning Tree Protocol, customers can
increase available bandwidth and
decrease network downtime with a
simple keystroke. Customers can now
increase reliability and performance
without restructuring the network.

Convergence-based
performance
performance
Application performance minimizes
packet delay and jitter when the traffic
load increases on the switch. Wire-speed
routing and Quality of Service (QoS)
mechanisms deliver the performance
required for applications such as IP
Telephony, as well as multimedia and
collaboration applications. A non-
blocking switch fabric, together with
hardware-based routing, decreases the
chance that data will be dropped when
the traffic load increases on the switch.
The policing and shaping features
permit traffic flows to be controlled
based on applications needs. With

QoS
Being able to classify, process and expe-
dite traffic based on an application’s
requirements is more important than
ever. QoS and the ability to prioritize
traffic are what enable a switch to
support bandwidth-sensitive applica-
tions. By assigning QoS levels to traffic
flows, applications can get the band-
width and network priority demanded by
specific applications. Four priority queues
are the basis for QoS in the Ethernet
Routing Switch 1600. Combined with
wire-speed routing and filtering, the
Ethernet Routing Switch 1600’s QoS
features enable application-based solu-
tions to be implemented when and
where you need them most.

Routing performance
Wire-speed routing and a non-blocking
switch fabric provide the basis for a
network designed to increase collabora-
tion and productivity. IP Telephony,
Customer Relationship Management
(CRM) and collaboration applications
promise great increases in employee
productivity.

Security
Security features provide added protec-
tion for switch configuration data, while
packet filtering helps secure and segment
sensitive traffic or network access.
Support for Simple Network Manage-
ment Protocol (SNMPv3) and Secure
Shell (SSHv2) supply protection for
tion for switch configuration data, while
packet filtering helps secure and segment
sensitive traffic or network access.

Multi-level access and defined access
policies help secure the switch against
unauthorized management access.
Packet filtering provides an additional
means to segment and secure sensitive
traffic or network access. Support for
RADIUS and TACACS+ gives customers
the freedom to use current security
databases.

device configurations or eavesdropping
on configuration command sessions
represents real security concerns. Switch
configuration information and its
integrity are critical to maintaining a
mission-critical network. The Ethernet
Routing Switch 1600 supports SNMPv3
and SSHv2 for controlling switch
configuration information. SNMPv3
provides services for sending and receiving
messages, authenticating and encrypting
messages, and controlling access to
managed objects. SSH specifies the way
to conduct secure communications over
a network. Together, these protocols
help ensure that access to critical network
resources, like the Ethernet Routing

Summary
As competition in the marketplace
intensifies, there will be more pressure
for networks to support additional
applications and the ability for a network
to adapt and perform will become more
critical. Core network routing represents
an area where technology will be asked
to deliver much in the way of perform-
ance and resiliency. The Ethernet Routing
Switch 1600 Routing Switch meets
these challenges head-on by combining
resiliency, performance and security into
a high-performance 1U high solution.
With this addition to the Ethernet
Routing Switch LAN portfolio, Nortel
continues its position as a complete
“end-to-end” enterprise solution company.
