These days our networks have to handle large amount of traffic, serve thousands of clients. It is very difficult for a single server to handle such huge load. The solution is to use multiple servers with load balancer acting as a front end. The clients will send the requests to the load balancer. The load balancer will forward the client requests to different servers depending upon load balancing...
We propose a scale-out solution for deep packet processing (DPP) appliances, which uses a standard Ethernet switch in combination with a load balancing controller. The majority of the data-plane traffic is distributed via the switch's built-in traffic distribution function and no connection state is kept. If the load balancing controller detects a skew in the load of the DPP appliances, it updates...
Verifying new hardware systems is a daunting task. To reduce the amount of effort involved, verification teams attempt to reuse as much verification IP as possible. We introduce a novel approach for test generation that enables the reuse of verification IP to verify new functionality. This method applies to a significant category of features, which are variations on the functionality of an existing...
With the rapid growth of both information and users, how to effectively improve the quality of network service becomes an urgent problem to be addressed. Load balancing is to overcome this problem in an effective way. At present it is mainly achieved by the load-balancing hardware and software, but there are also many problems, such as unscientific and inaccurate algorithm, imperfect and impractical...
To increase the application accuracy of the inertia instrument, a distributed network test system for inertial instrument is designed and realized, on the base of analyzed the test contents, test parameters, network architecture, and network test mode. The system has four layers composite architecture based on C/S/B network model. The scheme of automatic test based on VXI bus was adopted in the field...
The increase of the web traffic has created the need for web switches that are able to balance the traffic to the server farms based on their contents (e.g. layer 7 switching). In this paper we present a web switch implemented in a multiprocessor reconfigurable platform augmented with hardware co-processors. The system supports the TCP splicing scheme to accelerate the routing of the packets by forwarding...
A significant challenge in today's Internet is the ability to efficiently incorporate customizable network intelligence in commercial high performance network devices. This paper tackles the challenge by introducing the Active Flow Manipulation (AFM) mechanism, a key enabling technology of the programmable networking platform Openet. AFM enhances the control intelligence of network devices through...
