Obrigado !!!
Today, together with our reseller channels, we are successfully meeting our mission of providing our products to enterprises, ASPs, and service providers who recognize the necessity for e-business applications and how they affect their public and private networks. 
First, a little about Sitara Networks. We were founded by Malik Khan, a true network visionary with over 20 years experience in the industry. Malik was the VP and General Manager of the Motorola Networks Systems Division. This division both originated the cable modem and generated the idea for Sitara Networks. 
Whenever cable modems were tested in a lab environment against traditional modems, cable modems consistently proved to be the hands-down winners. The surprise came when testing was performed in the real world of downloads and the Internet. In this arena, cable modems saw their superiority vanish due to network problems that hampered information transfer. Malik believed this problem could be overcome and built a team from a broad range of wide area networking companies that included Motorola, Bay/Nortel, Cisco, Lucent, 3Com, and IBM. 
Since those early days, Malik and his staff have formulated key partnerships with such companies as Primus Telecomm, a telecommunications applications service provider; Citrix, a remote application management company; and Sumitomo, a major distribution partner. 
Since our inception, we have received more than $49M in venture funding backed by a broad range of partners. This funding started with some of the leading lights in the communications industry: Charles River, New Enterprise Associates, and One Liberty. 
Our technological success has been further fueled by our partnerships with AOL and Intel. In fact, Intel is where we acquired the QuickWeb caching technology that provides a lot of the enhanced high-performance caching capability of the Sitara Networks product.
Presenter’s Note QuickWeb enhances squid capabilities. A discussion of squid is not recommended unless the customer understands squid. 
Squid Note The latest version of squid is enhanced by Sitara to allow squid to work cooperatively with the other parts of traffic management in our product. 
Todas as novas aplicações que são criadas são preparadas para rodar sobre IP, uma rede IP realiza sempre o melhor esforço (best effort) , a inteligencia da rede esta nos equipamentos de pontas para indicar se o pacote chegou correto ou não.
Novas aplicações ERP, CRM,Streaming video (Media), VOIP
Mais banda não é necessariamente a solução , custo,não priporiza as aplicações críticas e consumida logo.
Convergencia só será realidade a hora que as aplicações receberem o tratamento necessário (voz imagem) necessidade debanda e snsibilidade a atraso.

Gerenciamento efetivo do uso da rede
Today even large capacity networks must deal with congestion that results in problems, conflicts, and applications that do not perform effectively or efficiently. This situation is caused by application development that does not design applications to run on a network that shares resources among multiple applications. The solution -- redefine the network to guarantee service for the mission-critical applications.
In the good old days networks were principally costly IBM SNA networks acting as mini networks running applications on central servers with simple remote sites. These applications were easy to manage because each system ran only a small number of applications and these applications were designed to be very effective and to peacefully run on the current resources. 
Today’s networks are central sites with branches accessing several application types and the Internet. These systems are not easy to manage because of the massive volume of traffic and because the applications were not designed with the network resources in mind. These facts, combined with the lack of traffic controls, leaves today’s networks with the traffic competing for resources, potentially bursting, and even preventing business critical applications from working effectively.
This can be remedied with the QoSWORKS system and its ability to make enforcement decisions that buy back great chunks of bandwidth. For example, many times 30 to 40 percent of the web traffic moving through a connection can be cached to save the bandwidth at the branches. 
Voice and video applications cannot run until business sense is applied to the network and resources are doled out.
Today’s networks support a broad range of applications that range from latency insensitive text-based email requiring very little bandwidth, to high-latency-sensitive videoconferencing that requires very large amounts of bandwidth.
Managing these applications and the network resources can be complicated. For example, when an e-mail with one or more attached PowerPoint presentations is sent to multiple users, large amounts of bandwidth are required and network congestion can result. Delaying the e-mail traffic reduces or even eliminates this congestion and allows more latency-sensitive traffic to utilize the resources. This peaceful co-existence is necessary to guarantee high latency-sensitive business critical applications run uninterrupted.
Business critical applications often require terminal mode transactions for order entry, stock trades, database query, etc. These types of applications can be significantly impacted by even single second delays. In addition, today’s e-businesses are often migrating to more broader types of applications such as videoconferencing and voice traffic (voice over IP) that are both very high bandwidth and very high latency sensitive. While these applications can be of great value, as they reduce travel and save money on voice calls, they greatly impact a network. One solution is to control the times of day that these resource intensive applications are allowed to run. That is, become aware of what applications are business critical, when they must run, and what resources are required. For example, do not schedule a videoconference when end-of-year accounting is running.
In response to these needs, Sitara Networks offers the QoSWORKS system. This system monitors, analyzes, and doles out network resources to handle each and every application on a shared network, and results in managing the competition among all these application types.
Sitara Networks introduces the QoSWORKS system, the first quality of service appliance that addresses quality of service deployment in real business networks today. 
The QoSWORKS system:
Is based on an open, standards-based platform that can be extended to handle newly emerging applications
Bundles all quality of service tools and techniques in one box making the system quick, easy, and cost-effective allowing the network manager to avoid the time and expense of managing additional resources
Is easy to integrate and manage using its web-based and command line interfaces 
The QoSWORKS system incorporates all of the tools necessary to manage a network.
Our intuitive policy management includes both web-based and
command line interfaces to easily and simply identify and manage traffic, and to generate the real results quickly and easily. 
Presenter’s Note: The policy management on a router is difficult to change, as it requires modifying access lists in huge text files. 
Sitara’s AccuRate traffic management system includes TCP rate shaping, class-based queuing (CBQ), packet-size optimization, and fair allocation of bandwidth by connection.
TCP rate shaping allows for very accurate control of TCP-based transactions. This includes preventing specific traffic from entering the network. 
Class-based queuing is a highly accurate means of controlling traffic moving through the system. It uses a hierarchical queuing system to accurately represent bandwidth allocation. 
Presenter’s Note: Traditional queue-based control mechanisms do not manage oversubscribed frame relay networks. On the QoSWORKS system, CBQ manages the wire traffic and sends the rate feedback and queue size information to the rate shaping mechanism. This cooperation and efficiency would not be possible if the two techniques were managed in separate boxes.
The one box, multi-solution QoSWORKS system effectively manages dynamic networks by intelligently deploying the right tool for the right application type. We have documented our industry-leading throughput and response time for critical applications (Tolly white paper reference) and accurate policy enforcement. 
The QoSWORKS system ensures optimum utilization of bandwidth without ever applying any formal or artificial limitations. We have verified our network efficiency through reports and graphical representations that track how the network is performing, where the bandwidth is going, which applications are using it.
In addition, we have proven the superiority of the QoSWORKS system at sites where no quality of service expertise exists, and only traffic types and management criteria have been defined. 
	The six LEDs on the front panel of the pizza box provide you with specific information about the power, status, link, and port activity.
Emphasize that the values here are sample values only - not meant as recommended values for the customer’s network.
Point to packet-size optimization (called “Max Trans Unit”) and Max. Queue Delay on the GUI. Note that packet-size optimization is only used for TCP-based traffic - this is why this field is not filled in here. 
The Policy Editor screen in the QoSWORKS UI is used to define the traffic hierarchy. This example shows the headquarter perspective where the traffic is broken up into multiple physical links to the branch sites. This division is possible because class-based queuing can configure bandwidth to exactly mirror how a network actually operates. 
This comprehensive display includes information about how the traffic is managed and how the policy sets are defined. 
The QoSWORKS system can set the policies according to time of day. That is, define the same policy different ways for the business day and outside the business day. For example, if an overnight batch job must run and a specific bandwidth access is required to guarantee the job completes, set the overnight policies to account for the bandwidth requirement.
Note: Other products in the marketplace require compromises when defining bandwidth utilization.

Note: Other products in the marketplace require compromises when defining bandwidth utilization. 
The Policy Benefits screen in the QoSWORKS UI is used to display a snapshot of performance vs. all of the policies that have been set in the QoSWORKS system. This example shows a typical view of a relatively complicated network with multiple physical links and the traffic distribution for each link. 
This page also shows each of the policies and the current utilizations in the bar graph with the overall bandwidth allocation that has been guaranteed and the allowable burst.
Notice the orange coloration as a particular class begins to burst into its burst area. This graph provides a quick, simple at-a-glance look of the how the network and the policies are performing. 
The QoSWORKS system is the first fully integrated solution built on open platforms for quick addition of features. It provides the highest throughput, fastest response time, and the most accurate policy enforcement for critical applications. 
The QoSWORKS system is also the first quality of service solution that is easy to deploy and manage. In fact, the policies can be up and running in 15 minutes.
When these benefits are combined with the low cost of the package, the QoSWORKS system is truly the most cost-effective quality of service solution in the marketplace today.
Presenter’s Note: It is recommended that you bring copies of the Tolly report to customer meetings. It is available through our web site. The test compared QoSWORKS and Packeteer PacketShaper. It is important to note that the throughput figures were gathered without caching enabled (on AccuRate alone). Results with caching would be expected to be much higher (as long as there was cacheable traffic on the network).
Tolly Labs, the leading data communications equipment test house, performs test evaluations among competitors in the marketplace. During a test against the Packeteer PacketShaper we delivered 19% higher throughput. This means we are efficient and can move more information through a particular constrained resource because we have that wide area pipe. We can also give you almost 20% more utilization capacity because we are more accurate in managing that traffic. This means that when there are sudden shifts in the way traffic is moving we make sure the critical applications take advantage of that by plugging the holes in the data flow. This comes from the 22% greater accuracy in policy enforcement than point quality of service products.
Note: Accuracy refers to the amount of deviation from bandwidth limitations - if we allocate 20Kbps of bandwidth to a given application, we deliver very close to 20Kbps. This is not so for our competition, who may deliver 10Kbps, 30Kbps, etc.
