This article will attempt to outline the problems that many organizations face with their network today, and identify methods that Exinda and our x60 WAN Optimization appliances use to provide exceptional control of misbehaving network traffic, recreational application traffic and other non business critical network traffic that consumes scarce network bandwidth.
The top problems that organizations are trying to solve
1. User experience / customer satisfaction – User complaints about the speed of the network.
2. Application issues – Specific applications performing slowly (ie – student registration system, off-campus access, CRM, backups, centralization/consolidation/virtualisation efforts etc)
3. Rising network costs – I am running out of bandwidth. When do I need to buy more, and how much do I need?
4. Aggressive and/or recreational applications – Certain users or user groups are eating up the bandwidth which causes problems for other users.
5. Productivity – Measuring time wasted by employees and helping to remedy.
Savvy network managers therefore are looking to provide users with the best network experience possible by maximizing the speed and efficiency of their applications over wide area networks (WAN). In discussions with our customers we have identified a series of requirements that seem to be almost universal in nature. These clients not only need to ensure that business-critical application(s) perform at acceptable levels of service, and can benefit from the maximum application performance possible they have determined that their WAN Optimization solution should:
- Serve environments with the ability and/or need to run bandwidth-eating applications on the network where controlling access and even blocking access as needed is an absolute requirement.
- Serve a variety of users with a wide range of application requirements.
- Be deployable by organizations with a limited number or no dedicated IT staff serving multiple locations, wearing multiple hats, without the luxury of time to focus on the network.
- Be suitable for an organization needing an affordable and complete solution for WAN performance issues with multiple locations having applications utilizing a WAN
Exinda’s unified performance management (UPM) solution brings together a suite of advanced, best-of-breed, visibility, traffic-shaping and WAN optimization technologies into a single, easy to-use appliance designed to improve network productivity. Exinda is the only Unified Performance Management solution on the market. Unified Performance Management provides users with a tightly integrated, cost saving solution to getting the most out of your network. All controlled through a unified management console the Service Delivery Point a cloud computing based network management system.
An organization that opts for an Exinda x60 WAN Optimization platform running our ExOS 5.4 software should experience the following improvements in WAN performance:
Reduce set-up time by 50% to 80%, for multi-site WAN optimization deployments.
Exinda’s auto discovery and configuration turns a problem that once took days and hours, into a solution that takes just minutes.
Exinda drastically simplifies deployment of WAN optimization technology. Exinda’s intelligent architecture provides Exinda appliances with the ability to recognize one another, share configuration settings and automatically sync to accelerate traffic and improve network efficiency.
This means no longer needing to…
- manually create tunnels between devices,
- reconfigure QoS policies,
- apply changes to clients, servers, routers, or IP addresses in order to accelerate traffic between devices.
Exinda is smart enough to do the work for you.
Reduce up to 90% of WAN data.
Exinda’s universal WAN memory cache removes repetitive data from being resent over the WAN. The overall reduction in traffic increases application speed and frees up bandwidth.
Make the most out of de-duplication efforts and deliver warm pass results bi directionally without the need to partition disk space at each branch office or endpoint.
The universal cache also improves storage efficiency on all Exinda devices.
Improve Delivery Time 50-100x
Improve data delivery 50 to 100 times. Since data is now accessed locally from the disk cache, users now experience LAN speeds over the WAN.
Improved TCP Delivery (Layer 4 Optimization)
Mitigate the negative impact high latency has on TCP delivery. Exinda uses the latest in layer 4 optimization techniques to ensure fast and consistent TCP transmissions.
These techniques allow Exinda users to bypass traditional TCP problems where it will not send additional data until an acknowledgement is provided from the other side of the transmission.
Techniques used include: TCP window scaling, selective, local, and delayed acknowledgements, packet aggregation, TCP fast start, and the ability to implement control mechanisms to reduce network congestion.
Technical Benefits of a UPM solution include:
- Reduction in packet loss & retransmissions
- Improved performance through reduction in acknowledgements required from packets
- Improved congestion control across a variety of network environments
- Increased connection throughput early into the connection
- Increased speed in packet transmission through acknowledgment of multiple packets at a time
Reduce User Experienced Latency (Layer 7 Application Acceleration)
Exinda uses a variety of techniques to improve the efficiency of WAN communications and advance a network user’s experience. The use of Layer 7 application acceleration, encompassing methods such as compression, prefetch data, and local cache, allow Exinda to reduce an application’s footprint on the network and improve usability.
In my next posting I plan to outline some of the visibility attributes of an Exinda x60 and ExOS 5.4 enabled Unified Performance Management solution.
