Certeon's WAN Optimization Solutions

Tell Me More

Many IT managers try to mitigate WAN issues by just adding more bandwidth, only to discover that the effects of high latency and packet loss still impact remote application access performance, even during non-peak network times. This opened up the opportunity for multiple WAN optimization techniques such as compression, caching, and differencing, and products such as asymmetrical and symmetrical network devices to make their way into the market. Certeon's aCelera Virtual Appliance approach to WAN optimization falls into the symmetrical class of devices, with some major differences in how Certeon optimizes the application traffic from other vendors.

Symmetrical WAN Optimization Techniques

The Certeon aCelera is deployed in software on each side of the WAN link to accelerate application response times. Certeon incorporates a number of techniques to minimize the impact of WAN issues on application performance - all transparent to existing clients, servers, and applications. Certeon’s WAN optimization techniques are discussed below.

Traditional WAN Optimization

Certeon employs many traditional network optimization techniques, including the following:

Forward Error Correction (FEC) enables the receiving node to regenerate these lost packets without the extra latency of retransmitting them. With FEC, the sender adds one or more Error Correcting Code (ECC) packets to a group of data packets, and the receiver uses the ECC packets to regenerate any lost or significantly delayed data packets (up to the number of ECC packets). Certeon utilizes both QoS and FEC for traffic control and error correction.

Application Intelligent Networking

The key challenge remaining is to significantly reduce the amount of Web data that needs to be sent over the WAN, thereby reducing response times and increasing the ability to support a greater number of remote users. Application-aware acceleration methods, such as Certeon's Application Acceleration Blueprints and Object Differencing Engine (ODE), provide much higher levels of data reduction and hence application acceleration. The Blueprints identify specific application objects, and the ODE maximizes the differencing between those objects and sends only those differences over the network. No changes are made to the client or server software or system - acceleration is fully transparent.

Key attributes of Application Intelligent Networking include:

Certeon reduces application response time over the WAN by over 95%. Learn more about aCelera Virtual Appliance for Application Acceleration software.
