APPLICATION PERFORMANCE MANAGEMENT
 
Our solutions deliver data to monitor applications in real time and analyze application latency and response times. This helps network managers optimize the efficiency of their applications and network infrastructure.
 

 

TROUBLESHOOTING AND COMPLIANCE 
 
Our solutions deliver data to applications that provide access to all information that has passed through the network in the order it was received. This allows network managers to comply with regulations, as well as analyze problems from historical data. It also allows them to take actions that will prevent problems from recurring in the future.
 
 

 

NETWORK BEHAVIOR SIMULATION
 
Our solutions deliver data to, and receive data from, applications that enable telecom operators to simulate real-life subscriber behavior with a variety of applications and services. These applications generate insights that lead to better decision-making regarding infrastructure, service upgrades, and deployment.
 
 

 

NETWORK AND CONTENT SECURITY 
 
Our solutions deliver data to network appliances such as Intrusion Prevention Systems (IPS) that can see every detail within the networks they are protecting. They can stop attacks, as well as protect against data leaks, while at the same time ensure there is a 100% accurate record of everything that happened.
 
 

 

FULL LINE-RATE TRANSMIT
 
Full line-rate transmit is an important capability for a number of test and analysis applications. Testing network performance under maximum load is increasingly important to not only assure quality of experience, but also to harden networks against attacks, such as Distributed Denial of Service (DDoS) attacks. 
 
Napatech accelerators make it possible to build solutions where the maximum transmission capability can be achieved to thoroughly test network resilience.
 
With Napatech accelerators, the frames to be transmitted are either generated by the application, replayed frames that were previously captured to disk, or retransmitted frames received in an in-line configuration.
Frames that are generated for transmission, or host-based transmit, allow frames to be generated by the host and transmitted at line speed on the network. This is useful for load-testing of networks and devices or simulating network behavior for network management and security testing. Timing can be important in these cases to ensure that the right frames are transmitted at the right time and in the right order.
 
Replay-from-disk allows previously captured frames to be analyzed for troubleshooting or security purposes. In this case, it is important that timing is preserved to accurately recreate what happened. It can also be useful in these cases to change behavior to simulate different situations. For example, it can be useful to manipulate the inter-frame gap (IFG) to speed up or slow down transmission.
 

 

MULTI-CPU DISTRIBUTION
 
Modern servers provide unprecedented processing power with multi-core CPU implementations. This makes standard servers an ideal platform for appliance development. But, to fully harness the processing power of modern servers, it is important that the analysis application is multi-threaded and that the right Ethernet frames are provided to the right CPU core for processing. Not only that, but the frames must be provided at the right time to ensure that analysis can be performed in real time. 
 
Napatech Multi-CPU distribution is built and optimized from our close knowledge of server architecture, as well as real life experience from our manufacturing customers.
 
Napatech accelerators ensure that identified flows of related Ethernet frames are distributed in an optimal way to the available CPU cores. This ensures that the processing load is balanced across the available processing resources, and that the right frames are being processed by the right CPU cores.
 
With flow distribution to multiple CPU cores, the throughput performance of the analysis application can be increased by orders of magnitude. Not only that, but the performance can also be scaled by using faster processors or more processing cores. 
 
Napatech accelerators support different distribution schemes that are fully configurable:
 
  • Distribution per Port: All frames captured on a physical port are transferred to the same CPU core for processing
  • Distribution per Traffic Type: Frames of the same protocol type are transferred to the same CPU core for processing
  • Distribution by Flows: Frames with the same hash value are sent to the same CPU core for processing
  • Combinations of the Above

 

FRAME CLASSIFICATION
 
Ethernet-based networks are designed to be generic, frame-based media for carrying all kinds of protocols, not only TCP/IP. For users who want to monitor their network traffic in the most efficient way, it is therefore important to be able to recognize as many protocols as possible.
 
Napatech accelerators have a unique set of features for extracting information from the layer 2-4 network traffic. Header information for the various protocols transported over Ethernet is made available for analysis. This includes encapsulation and tunneling protocols.
 
The protocols that Napatech accelerators can recognize include:
 
• Protocols: IPv4, IPv6, UDP, and TCP
• Encapsulations: ISL, VLAN, and MPLS
• Tunneling Protocols:  GRE, SCTP, IP-in-IP, and GTP
 
When combined with deep packet inspection (DPI) software from Napatech partners, this information provides deep and real-time insight into what is happening in the network right now.
