VistaOne can see what’s on your enterprise network. We know why it’s slow. We know who’s soaking up all your bandwidth. We know what apps are giving it trouble. Give us access. We’ll tell you.
In one week-long look through our Packeteer appliance, VistaOne can tell you what’s right with your corporate WAN and what could be better. What’s more, we can tell you what threatens your data exchange now and down the road.
VistaOne can look at several locations over a designated period. Then, we study and report:
VistaOne pays particular attention to any area you’ve identified trouble (for example, slow Microsoft Exchange traffic, hesitation and drops in voice traffic, etc.).
We deploy our Packeteer PacketShapers at specified locations to collect data for the analysis. We install at the core and edge of the network for at least one week, to get a complete picture of what’s happening and a realistic view of network behavior—a sort of snapshot in time.
The PacketShapers gather statistics on the types of traffic, the top users, the latency of specific applications, and WAN performance based on bandwidth utilization and retransmissions. VistaOne experts then compile a report. We focus on the locations experiencing the most severe performance issues and follow with recommendations for their resolution. We intently examine the three critical areas:
Traffic Discovery
Traffic Discovery is the process of identifying the application and traffic types that are running over the wide area link for a specific location. The objective for this analysis is to identify the ten most active applications and reveal the bandwidth usage for each application in bits-per-second as well as the percentage of total bandwidth used by each application for inbound and outbound traffic.
Network Efficiency
Next, we analyze bandwidth use in comparison to the CIR and port speed. The number of retransmissions gives us an idea of packet loss across the network, which can be indicative of congestion or over-subscription. The example graph below indicates that during most of the day, retransmitted packets are rare. In this 
sample, the percentages represented indicate that on average, 100% of the throughput is good. That means packets are not being retransmitted. If there is a decrease in percentage of throughput, we suspect network congestion and/or overflowing router queues. Both can cause packet loss and timeouts, forcing retransmissions and exacerbating the original problem.
Bandwidth Utilization
Network Utilization is designed to show a link’s average and peak bandwidth consumption in bits-per-second. Average bandwidth alone doesn’t tell the complete story. Averages, especially over long periods of time, can lead to the false conclusion that ample capacity exists. That’s why we examine peak utilization. Peak reports can reveal traffic that is hitting a capacity limit frequently. During these periods, applications compete for bandwidth and performance suffers. Often, it’s the business-critical apps sitting in queue.
Network Analysis Benefits
VistaOne’s observations and recommendations can help you improve the performance of your network, increase security and reduce costs. They can include:
Result: satisfied users, consistent strong performance, improved security and a network that is easier to manage.
