X-Series for Enterprise Backbone Aggregation
and Campus Connectivity
Enterprises depend on modular,
multi-layer, high-performance
switch routing solutions, providing
aggregation from the wiring closet
and between sites. This facilitates
segmentation and routing of traffic
between buildings, floors, and/
or departments. X-Series chassis-
based solutions have been explicitly
designed to perform this task,
enabling high-speed campus
connectivity between local area
facilities and access to the
data center.
High-performance distributed computing increases the demand for
secure campus networks. At the same time, business-critical systems and
services are becoming increasingly dependant upon enterprise backbone
infrastructures. X-Series secure core routers have the capacity, scalability,
and QoS functionality required to deal with these new demands.
Architected to ensure no single point of failure with the capability to
ensure transparent software recovery mechanisms, business continuity is
enhanced still further via the implementation of logical Layer 2 and Layer
3 resiliency protocols such as rapid spanning tree (802.1w), multiple
spanning tree instances (802.1s), link aggregation groups (802.3ad),
and Virtual Router Redundancy Protocol (VRRP).
X-Series provides high-density Gigabit Ethernet and 10 Gigabit Ethernet and
supports a wide array of optics to provide short-haul campus connectivity.
Total cost of ownership (TCO) is among the lowest in the industry and
future I/O module upgrades will increase throughput and switching.
X-Series for Enterprise Data Centers
A secure data center provides enterprises with ultra high performance
and density, enables granular control of IT assets and applications, and
assures protection against existing and emerging business continuity
threats. Key components of any data
center infrastructure include high-
port density (especially for Gigabit
Ethernet), secure high-availability,
plus flexible and powerful QoS
capabilities. The X-Series delivers
unrivalled high-performance,
scalable routing for enterprise
data centers, supporting over
2.5 Tbps switching capacity,
256 10 Gigabit Ethernet, and
1024 10/100/1000 Ethernet
interfaces in a single rack.
The data center is the heart of
corporate enterprise infrastructures
and it is crucial that security and
continuity are not compromised for
performance. The X-Series has been built from
the ground up to protect the network core and data center. Dedicated,
multiple classes of service for granular traffic control, policers, and traffic
shapers mitigate DDoS attacks and enhanced QoS guarantee predictable
availability for mission-critical applications, such as VoIP. Support for up
to 8 queues per port enables the highest level of granularity in terms of
shaping and prioritizing application traffic within a data
center environment.
Enterprise customers can use Virtual Routing and Forwarding (VRF)
to implement virtualization of network resources to support separate
security and application domains for different departments and groups
in the organization. VRF provides data center virtualization by allowing
multiple virtual routers to reside in a single hardware platform and
central location while providing access to a common infrastructure.
X-Series for Internet Exchanges
Both port density and switching capacity are needed by Internet
exchange points to accommodate expanding numbers of customers
and traffic growth. With industry-leading, high-density gigabit support,
the X-Series is an ideal solution for these exchanges. Larger Internet
exchanges are starting to exceed gigabit speeds for individual customers,
therefore economical 10 Gigabit Ethernet — rate limited as appropriate
to sell increments of bandwidth — provides additional options to
gracefully accommodate traffic growth for high-end customers.
The X-Series provides Internet exchanges with a solution based upon
industrial-strength security, enabling the confident implementation of
strict Service Level Agreements (SLAs). In order for providers to offer
competitive SLAs to customers, the network has to be more reliable than
ever before. Only the X-Series has been designed from the ground up to
offer this type of secure, carrier-class architecture.
