In a converged world, reliability goes
beyond individual nodes and is meas-

across the network — providing trusted
and dependable fail-over that is consis-

Switch Clustering
Nortel’s advanced resilient technology
— Split Multi-Link Trunking (SMLT)
— provides complete protection against
any individual component, link or node
failure. This solution provides for sub-
second recovery combined with user
session-based load-balancing — all
leveraging standards-based link aggrega-
tion at the network edge (user or server).
Deploying the ERS 8300 in the core is
the ideal solution for delivering highly-
available services.

High availability chassis-based
solution
As a stand-alone device, ERS 8300
provides an extremely robust platform
for resilient networking. The system
supports dual redundant switch fabric
modules, N+1 power supplies and hot-
swappable modules and fan trays.

Precision performance
Real-time applications are sensitive to
variable performance and are relatively
bandwidth-intensive. Performance is
closely linked to reliability. Many of the
design options for today’s networks can
be a trade-off between performance
needs and reliability requirements.

Performance architecture
At the heart of the ERS 8300 is a
passive backplane design and a distrib-
uted forwarding architecture that lever-
ages the advantages of dual N-1,
active-active Switch Fabrics. The 720
Gbps Crossbar and the new 8394SF
Switch Fabric module deliver up to
464Gbps of genuine data throughput
and 345Mpps of frame-forwarding
performance per switch. Putting these
figures into a business context, an ERS
8300 Core Switch Cluster can transport
more than 60,000 average-sized office
files per second, and still not be subject
to contention.

Advanced Quality of
Service (QoS)
The ERS 8300’s QoS features allow
more efficient use of bandwidth to opti-
mize existing network resources and
capabilities, and also provide packet
classification and marking at the edge of
the network to simplify the QoS solu-
tion at the core. By classifying, priori-
tizing, policing and marking LAN
traffic, networks can deliver the right
service levels for mission-critical and
quality-sensitive applications. The ERS
8300 provides eight hardware queues per
port. Advanced QoS features support
the standard Internet Engineering Task
Force (IETF) Differentiated Services
(DiffServ) QoS architecture — packet
classification based on the contents of
the IP Packet Header fields (e.g., voice,
video and data).

Traffic Policing and Shaping
Traffic Policing enables the provisioning
of different service levels by limiting
traffic throughput at the ingress
(inbound) port of the ERS 8300. This
feature ensures that limits can be placed
upon the amount of bandwidth that
particular users or applications can push
into the network. An associated capa-
bility — Customizable Auto-Negotia-
tion Advertisements (CANA) — allows
for only specified connection rates to
be advertised by auto-negotiation, and
therefore limits low priority devices to
the appropriate connection speed.

Traffic Shaping offers the ability to limit
traffic on egress (outbound) from the
ERS 8300, typically to comply with
some form of service tariff. Enterprises
working with service providers or
carriers can use this feature when they
deploy Ethernet as an alternative to
traditional Frame Relay or ATM WAN
access solutions.

IP Filtering
IP Filters can be used to manage traffic
and provide security, by ensuring that
specific actions are performed when
defined criteria are matched. Only data
that matches the pattern is allowed to
pass through the filter, and these filters
can be used to set traffic priority, drop
or allow IP packets, as well as define
the conditions for mirroring traffic
(e.g., IP telephony in a contact center
environment).

Convergence and Unified
Communications
Communications
The reality of today's networks is that
different applications must be given the
quality of service appropriate to their
differing needs and requirements. The
ERS 8300 facilitates enterprises’ transi-
tion to convergence-based applications
by implementing key enabling technol-
ogies while minimizing capital and
operational costs.
