Application QoS

Achieve true QoS by ensuring availability, effectively managing resources and prioritizing applications across the WAN.

The Challenge: Achieving True QoS

Having QoS is one thing. Achieving it quite another. QoS is impacted by every point on the network—from client PC to LAN to telecom carrier to the servers that process the transaction. Not all segments, however, are created equal.

Availability at Every Link

LAN-WAN Congestion

When high-speed LAN traffic transitions to lower speed WANs, congestion happens. It's just too much traffic for so small a WAN pipe. The result? Holds or drops—and real application performance issues.

Stuck Traffic, Retransmission, Disastrous Drops

When data is stuck in the queue, the application freezes and feels choppy. Or worse, it asks the server to retransmit—and duplicate data ends up competing for the same bandwidth. And once router queues are overwhelmed, packets drop completely. Application performance plummets dramatically.

Converging Customer Traffic

Converging customer traffic on carrier networks often creates congestion—depending on how a carrier balances supply and demand with capacity and bandwidth. Carriers may apply Committed Information Rates (CIR) and Excess Information Rates (EIR) to selectively allocate resources.

Is MPLS Help Enough?

MPLS helps QoS, but not nearly enough. MPLS does not:

• Manage LAN-WAN congestion
• Control competing inbound traffic
• Possess application intelligence
• Avoid reactive queuing mechanisms that degrade performance

The Packeteer Solution: QoS Delivered, Simply

Packeteer's suite of innovative, patented technologies overcome queuing device limitations to deliver true WAN QoS under a simple policy based framework with:

• TCP Rate Control
• UDP Rate Control
• Application Session Provisioning
• Behavioral Threat Suppression
• Application Marking
• Dynamic Subpartitions

Classify at Layer 7 Plus

Packeteer's Auto-Discovery mechanisms automatically classify hundreds of networked applications. Sub-classify applications into sub-applications and/or create custom classes.

Contain Recreational Applications

Cap or block recreational application use by simply categorizing it as low priority. Give business applications more bandwidth when need is high—tightly cap iTunes®, for example, while still granting Web browsing more leniency.

Suppress DDoS, Virus and Worm Propagation

Weed out security threats through Packeteer's Distributed Threat Suppression. Identify and isolate infected hosts, mitigating network impact. Our Flow Detail Records provide a detailed repository for forensic and compliance purposes.

Prioritize Critical Applications

Packeteer's application-intelligent QoS mechanisms make prioritizing simple. Allocate required bandwidth per session for sensitive real-time applications like ERP queries, transaction processing and VoIP—without wasting resources.

Allocate Remote Site Bandwidth

Inbound traffic gets compromised when a single connection—over hundreds of remote sites—connect over meshed Internet and MPLS-based networks. Only Packeteer delivers bi-directional QoS, with patented TCP rate control.

Contain WAN Costs

Controlling network resources helps contain costs. Just by trimming your recreational traffic by 30 percent—and allocating bandwidth to critical applications—you can enjoy up to a 30 percent savings on bandwidth.
