VLAN Comparison Report

The VLAN Comparison Report provides flow detail-derived views of network activity for each VLAN type identified by a flow-enabled PacketShaper. You can click on a linked VLAN ID in the first column of this report to drill down to a VLAN Detail Report.


Table Headings

The following list includes the column headings on the VLAN Comparison Report. The table can be sorted on any column by clicking on the column heading.

Heading Description
Average Jitter The average variation in speed detected. Not applicable to short duration flows
Average One Way Delay The average of all reported values for measured delay times in one direction of data flow
Bytes The total number of bytes used by this host pair during the report period
Efficiency Level % The percentage of bytes that did not require retransmission
Flows The type of data flow used
Host Transmit Speed The observed rate at which a host transmits data
Network Delay Average number of milliseconds packets spent in transit
Normalized Network Delay The transaction delay in the network, normalized by transaction size. It shows how long it takes to send 1Kb of data.
Packets The total number of packets exchanged by the host pair in the report period
Packet Loss Percentage The ratio of lost or dropped packets to total packets, expressed as a percentage.
PET Client Packet Exchange Time observed for the client
PET Server Packet Exchange Time observed for the server
Ping Exchange Time The round trip time for an ICMP PING protocol packet
Ping Success % The percentage of ICMP PING requests that received a response before the timeout value was reached
Server Delay Average number of milliseconds required for servers to process requests. The time starts when the server has received all required request packets and ends when the server issues the first packet of the response.
Throughput The rate of data exchange for this VLAN in bits per second
Total Delay Average number of milliseconds to complete transactions; includes network delay and server delay
Transaction Count The total number of unique iterations of a transfer of data or control detected during the report period
VLAN The VLAN ID number of a virtual LAN included in the report
