Introduction
The IntraCore® 35160 Layer 2 family of Gigabit Ethernet switches is Asante’s most powerful, flexible
range of backbone and aggregation switches.
With 16 ports of Gigabit Ethernet offered in two design options, your cost of ownership is reduced
considerably over other vendors switches by using mix and match GBIC/Copper ports.
By using a single-chip state-of-the-art architecture with shared memory, wire speed switching at Layer
2 is achieved on all ports.
Quality of Service
In the simplest sense, Quality of Service (QoS) means providing consistent, predictable data delivery
service. In other words, satisfying customer application throughput requirements including timing,
bandwidth and service prioritization.
QoS is to the ability of a network element (e.g. an application, host or router) to have some level of
assurance that its traffic and service requirements can be satisfied. To enable QoS requires the
cooperation of all network layers from top-to-bottom, as well as every network element from end-to-
end. Any QoS assurances are only as good as the weakest link in the "chain" between sender and
receiver.
For network’s that require more than just performance switching, the IntraCore® 35160 has a
comprehensive array of multicasting and Quality of Service tools to provide tailored service levels in
operations that involve Voice, Video, Image and Data traffic.
With future upgrade options that include Classification and filtering based on Layer 2 packets, Layer 3
protocols and Layer 4 protocols (TCP, UDP) and remapping priorities using DiffServ Code Point (DSCP),
traffic flows can be identified and managed by MAC address, VLAN, Port, source and destination
address.
Jumbo Packet Support
Jumbo Packet transmission is a requirement seen largely in Higher Education, Research and Distributed
Scientific computing environments, this commonly involves high level traffic flows of web, video and
database transaction processing between host and client.
Our implementation of Jumbo Packet support allows users to manually configure oversize frames of up
to 16384 bytes to be transmitted. Asanté’s end-to-end Jumbo Packet support includes FriendlyNET®
GigaNIX network cards also.
Low Cost Failure Backup Power Option
New to Asanté is the provision of an optional DC backup power supply to ensure continued operation in
situations of primary power failure. Used with Uninterrupted Power Supplies, Asanté IC 35160 can
ensure high productivity and extremely low downtime on mission critical networks.
The IC35-EPS12 operates at 12VDC and is used in standby mode simultaneously on-line with the 90-
260VAC primary power system. Should the primary power fail, the IC35-EPS12 automatically goes live
