Mobile Backhaul
ExtremeXOS is capable of providing carrier grade resiliency,
synchronization and high performance Gigabit Ethernet
switching for deploying true 4G mobile backhaul solutions.
ExtremeXOS-based switches supports two packet ring
resiliency protocols, Ethernet Automatic Protection
Switching (EAPS) RFC 3619, and ITU G.8032 standard for
Ethernet Ring Protection Switching, to enable carrier grade
resiliency for a superior subscriber experience and ensuring
service level agreements.
ExtremeXOS is capable of providing Synchronous Ethernet
through dedicated hardware support for ITU-T G.8262
Synchronous Ethernet (SyncE) and IEEE 1588v2 Precision
Time Protocol. SyncE distributes the clock between nodes
and provides the benefit of deterministic frequency
distribution. IEEE 1588v2 uses timestamps to distribute
both time and frequency between nodes. Synchronous
Ethernet ensures that 2G/3G TDM trac encapsulated
in TDM pseudowires and other Ethernet trac are
synchronized over fiber or microwave connections to
provide exceptional subscriber quality experience when
hand-o occurs between cell towers as subscriber roams
with their mobile devices.
ExtremeXOS and Ansible
Ansible network modules deliver the benefit of simple, powerful,
agentless automation to network administrators. Ansible
modules for ExtremeXOS can be used to configure, test and
validate existing network state on ExtremeXOS devices.
Extended Edge Switching
ExtremeXOS supports Extreme’s Extended Edge Switching
solution which simplifies the deployment and operation
of edge switches. Based on the 802.1BR specification,
Extended Edge Switching collapses multiple network layers
into a single-tier design that reduces the complexity of
traditional two and three-tier switch architectures. A central
ExtremeXOS aggregation switch can act as a single point
of control for multiple V300 and V400 edge switches and
seamlessly deliver ExtremeXOS services to these edge
switches. The solution, in eect, allows users to create
a “virtual” ExtremeXOS switching system, independent of
location, for simplified operations and reduced costs
Ethernet Audio Video Bridging
ExtremeXOS supports the latest IEEE 802.1 Audio
Video Bridging (AVB) standards to enable reliable,
real-time audio/video transmission over Ethernet for
today’s high-definition and time-sensitive multimedia
streams with perfect Quality of Service (QoS).
IEEE 802.1BA Audio Video Bridging Systems
ExtremeXOS uses these AVB technologies to identify
and reserve the network resources for AVB trac streams
and supports precise synchronous streaming capability
for reliable and high quality audio/video transmission
over Ethernet. The AVB protocols enables time sensitive
multimedia streams to be sent over the Ethernet network
with low latency and guarantees service quality for
today’s real-time, high definition information and
entertainment options.
