FastRecorder and PacketExtractor  for monitoring IP Network

Overview

Today's networks are built with switches, routers, and gateways interconnected with 1, 10, 25, 40, and 100 Gbps full duplex fiber optic lines. These fiber connections increasingly carry packets (vs. circuits) with data, voice, and video, interleaved, aggregated, and burst out at ever faster, bigger, and longer distances.

Diagnosing issues on these networks requires error free, non-intrusive interception at full line-rate (wirespeed) and then storing the captures for post analysis with a protocol analyzer. At such high rates, capturing and storing requires a unique architecture, large RAM, and hundreds of terabytes of storage. Additional features, like wirespeed filtering, packet slicing, storing and later extracting intended application streams are also vital.

The application includes four modules - FastRecorder™, PacketExtractor™, PacketRecorder™ , and PacketReplay™.

  • FastRecorder™ and PacketExtractor™ provide extreme wirespeed IP traffic filtering and recording up to 320 Gbps direct to disk and offline filtering, extraction, and analysis. Supports 4 x 1 Gbps or 2 or 4 x 1/10/25 Gbps or 2 x 40/100 or 8 x 10 Gbps or 4 x 1/10/25 GigE Ethernet Interface
  • PacketRecorder™ and PacketReplay™ provide record and playback of IP traffic up to 10 Gbps

In FastRecorder™ mode, high rate real-time traffic can be recorded with precise hardware time stamping. The Record feature includes a powerful Hardware Filter that allows user to filter out unwanted traffic, and continuously capture the traffic of interest. The user can apply trigger conditions to Start or Stop writing to the Disk based on the Trigger criteria.

In PacketExtractor™ mode, the recorded traffic file on selected network interface ports and drives can be extracted to PCAP or PCAPNG (Wireshark® format), or HDL (GL Proprietary format) formats, and extracted trace files can be analyzed using any packet analyzer such as GL's PacketScan™. It also supports sequence number verification of extracted packets (BERT verification) Live traffic captured on a network using the Recorder utility, PacketScan™, or Wireshark® can be easily recreated in the lab. Also, PacketExtractor™ supports monitoring and analysis of eCPRI protocol.

GL's IP Analytics™ tool along with FastRecorder™ and PacketExtractor™ application ensure Quality of Service (QoS) by analyzing IP-based data streams to meet performance standards. GL's IP Analytics™ offers detailed statistics for various parameters such as Layer 3, COS, Layer 4, IPv4/IPv6 Endpoints, UDP/TCP Endpoints, and conversations, enabling precise analysis of network performance. Capable to compute and visualize network metrics with millisecond precision, including Packet Count, Byte Count, Packets/sec, and Bits/sec, provides real-time insights crucial for optimizing network efficiency.

FastRecorder™ and PacketExtractor™ applications work with GL's PacketScan™ HD (or Wireshark®) Analyzers. GL's PacketScan™ HD is a complete IP traffic analyzer – similar to but more powerful than Wireshark®. For example, real time voice quality, fax quality, call and session separation, powerful ladder diagrams are included.

The traffic captured on a live network can be analyzed using packet analyzers such as PacketScan™ - All IP analyzer or Wireshark®.

FastRecorder™ Architecture

Fast Recorder working principle

The traffic is captured on the selected port at the hardware level. The captured traffic will be timestamped and sent to the Host Buffer within the hardware. If the Hardware Filters are applied, then only the filtered traffic will be sent to the Host Buffer. In case of multiple port selection, the filtered traffic from the selected ports is aggregated and presented as a single stream.

The FastRecorder™ application has two modules such as Capture Module and Write Module. In the host buffer, the packets are segmented into different frames based on segment sequence number and segment sequence length and these stream of frames are captured from the selected network interface and the write module will save the captured traffic in the trace files in metadata format in to the SSD/RAM Disk.

PacketExtractor™ Architecture

Extractor working principle

The pre-recorded captured files (.dat format) stored in SSD/RAM disk will be fed to PacketExtractor™ application.

It reads the metadata file which contains the information of the recorded data on each drive with time stamp. The filters can be applied for extracting traffic of interest. The trace files segments are reassembled based on segment sequence number. The segment sequence number and segment length are used while analyzing or reassembling the segments.
The Extractor module extracts the packets from the reassembled segments. The write module will write the extracted packets to HDL or PCAP or PcapNG. The BERT verify option can be used to analyze the sequence number of extracted packets.

FastRecorder™ Application

FastRecorder™ application provides various options to capture the high density real-time traffic on disk drives and store the recorded traffic into a file. The application can capture the traffic continuously until user stops the recorder or specify the size limit to stop the traffic capture.

PacketExtractor™ Application

PacketExtractor™ application consists of configuration settings that allows user to extract recorded files on the selected HD NIC interface port with or without applying filters and by specifying the different limit criteria (Time, Packet Count and Size) into required output file format to analyze the results using PacketScan and Wireshark application . User can also save the extracted traffic in multiple files by providing the file size to create a new file after every specified file size.

In the packet extraction from the stored recordings without filter the Extractor Filter option is unchecked and no filter configurations are done to extract the traffic.

IP Analytics™

IP Analytics™ plays a crucial role for monitoring and maintaining Quality of Service (QoS) in telecom networks. This involves analyzing IP-based data streams to ensure that voice, video, and data services meet predefined performance standards. IP Analytics™ provides detailed insight into recorded IP traffic captured at high speed. By analyzing IP traffic and data, telecom companies can enhance network performance, troubleshoot malfunctioning infrastructure, improve customer satisfaction, and increase operational efficiency. GL IP-ANALYTICS displays statistics for Layer 3, COS, Layer 4, IPv4 Endpoints, IPv6 Endpoints, UDP Endpoints, TCP Endpoints, UDP Conversation, and TCP Conversation.

At the core of IP Analytics™ lies its capability to capture all Ethernet packets and intricately organize them into flows, categorizing them based on key parameters such as IP Class Of Service, IP Address (both Source and Destination), and UDP/TCP Port Numbers (both Source and Destination).

IP Analytics™ enables you to categorize packets and flows with precision, offering several perspectives:

  • Flow based on IP Class Of Service: Understand how different classes of service impact your network's performance
  • Flow based on Unique IP Address: View the amount of traffic transmitted and received by individual IP nodes, offering insights into network load and potential bottlenecks
  • Flow based on IP Conversation: Analyze the traffic between pairs of IP nodes, enhancing your understanding of network interactions
  • Flow based on Applications: Identify application-specific traffic patterns based on TCP/UDP port numbers, crucial for application performance monitoring

Setting IP Analytics™ apart is its capability to compute and visualize crucial network metrics with millisecond precision. This includes measuring Packet Count and Byte Count for Each Flow, enabling assessment of data volume within each categorized flow. Additionally, dynamically calculating and plotting Packets/sec and Bits/sec offers real-time insights into network throughput. These metrics extend beyond individual flows to encompass each Ethernet port, furnishing a comprehensive overview of network performance.
