TELECOM NETWORK MANAGEMENT
Our solutions deliver data to applications that monitor critical Ethernet/IP connections in real time, as a supplement to information provided by traditional network nodes and interfaces. This improves underlying network performance and availability.
In mobile networks, all subscriber Internet traffic is carried in GTP (GPRS Tunneling Protocol) or IP-in-IP tunnels between nodes in the mobile core. IP-in-IP tunnels are also used in enterprise networks. Monitoring traffic over interfaces between these nodes is crucial for assuring Quality of Service (QoS).
Napatech accelerators open up these interfaces, providing visibility and insight into the contents of the tunnels. Analysis applications can use this capability to test, secure, and optimize mobile networks and services. To effectively analyze the multiple services associated with each subscriber, it is important to separate them and analyze each one individually. Napatech accelerators have the capability to identify the contents of tunnels, allowing for analysis of each service used by a subscriber. This quickly provides invaluable information to the application, and allows for efficient analysis of network and application traffic. The Napatech features for frame classification, flow identification, filtering, coloring, slicing, and intelligent multi-CPU distribution can thus be applied to the contents of the tunnel rather than the tunnel itself, leading to a more balanced processing and a more efficient analysis.
GTP and IP-in-IP tunneling are powerful features for telecom equipment vendors who need to build mobile network monitoring products. With this feature, Napatech can off-load and accelerate data analysis, allowing customers to focus on optimizing the application, and thereby maximizing the processing resources in standard servers.
MULTI-PORT PACKET MERGE
Napatech accelerators typically provide multiple ports. Ports are usually paired, with one port receiving upstream packets and another port receiving downstream packets. Since these two flows going in different directions need to be analyzed as one, packets from both ports must be merged into a single analysis stream. Napatech accelerators can merge packets received on multiple ports in hardware using the precise time stamps of each Ethernet frame. This is highly efficient and offloads a significant and costly task from the analysis application.
There is a growing need for analysis appliances that are able to monitor and analyze multiple points in the network, and even provide a network-wide view of what is happening. Not only does this require multiple accelerators to be installed in a single appliance, but it also requires that the analysis data from all ports on every accelerator be correlated.
With the Napatech Software Suite, it is possible to merge the analysis data from multiple accelerators into a single analysis stream. The merging is based on the nanosecond precision time stamps of each Ethernet frame, allowing a time-ordered merge of individual data streams.
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
IP FRAGMENT HANDLING
IP fragmentation occurs when large Ethernet frames need to be broken into several fragments in order to be transmitted across the network. This can be due to limitations in certain parts of the network or when tunneling protocols are used. Fragmented frames are a challenge for analysis applications, as all fragments must be identified and reassembled before analysis can be performed. Napatech accelerators can identify frame fragments and ensure that these are associated and sent to the same CPU core for processing. This significantly reduces the processing burden for analysis applications.
