each Cisco ACE module was brought online. In
addition to the linear scalability tests across four
Cisco ACE modules, the second scalability test
demonstrated how the Cisco ACE enables
scaling from 4 Gbps to 8 Gbps to 16 Gbps of
throughput on a single Cisco ACE module using
only a software license upgrade.

Performance Results
L4 CPS:
The Layer 4 connections per second (CPS),
concurrent connections, and throughput tests for
various server response file sizes were
performed on the Cisco ACE. Across the file
sizes tested, the Cisco ACE demonstrated
consistently strong performance. At the largest
server response file size (64K bytes), Spirent
Avalanche reached its CPS (~4.5K per device)
generation limit inhibiting the ability to determine
the maximum CPS limit for large server
response file size on the Cisco ACE module.

L4 Concurrent:
The Layer 4 Concurrent test results showed that
the Cisco ACE handled almost 4 million
bidirectional connections (Chart 4). Each of
these connections represents both the client-to-
DUT as well as the DUT-to-server side of the
connection.

L4 Throughput:
The Layer 4 throughput test at different response
file sizes shows a consistently strong
performance by the Cisco ACE. From files sizes
of 512K down to 2K (Chart 1, cover), the Cisco
ACE maintained a performance of greater than
12 Gbps.
L7 Results:
These Layer 7 tests differ from the Layer 4
series, as the traffic generated requires the
device under test (DUT) to perform TCP
termination, analyzing at least the first data
packet after the TCP setup sequence (SYN /
SYN_ACK / ACK) in order to make an intelligent
switching decision.
