What is Network Processing and What Does Sahab Do Here?

Network Processing could be simply defined as processing of packet-based digital networking data, which has several applications in different network levels.
Network processing is becoming an increasingly important paradigm as the Internet moves towards an architecture with more complex functionality inside the network. Modern network hardware and software not only forward packets, but also process headers and payloads to implement a variety of functions related to security, performance, and customization.
It is important to get a detailed understanding of the workloads associated with this processing in order to be able to develop efficient network processing engines.
Currently we have two main products here: A unique DPI engine and a traffic manager that is using it.

What Does Sahab Do

Deep Packet Inspection (DPI) is used for in-depth analysis of the packets sent over the networks that enables advanced network management, user service, and security functions as well as internet data mining.
DPI is used in a wide range of applications, at the enterprise level (corporations and larger institutions), in telecommunications service providers, and in governments. For instance, In addition to using DPI to secure their internal networks, Internet service providers also apply it on the public networks provided to customers. Common uses of DPI by ISPs are lawful intercept, policy definition and enforcement, targeted advertising, quality of service, offering tiered services, copyright enforcement, and statistics.
Our DPI engine called Phorcys can determine type of applications and protocols in encrypted network traffics without the need of deciphering them. Phorcys had overcome this obstacle with occupying new AI technologies (pattern recognition, machine learning, deep learning, etc.) for reaching the maximum precision with the minimum cost.
Main features and benefits of Phorcys are:

  • Detecting 150+ protocols and applications
  • Protocol parsing for HTTP, DNS and TLS
  • Using multiple techniques for protocol detection such as:
    • pattern matching
    • flow correlation
    • statistical analysis
    • heuristics
    • machine learning
  • SDK for developing customized protocol detectors

What Does Sahab Do About Traffic Management?

Network traffic management deals with the process of monitoring and controlling the activities of network besides transforming the network into a managed resource by improving performance, efficiency, and security. It also helps to operate, administer, and maintain the network systems.
Our Traffic Management and Monitoring product have these characteristics:

  • Wire-speed packet processing engine on a single 10G NIC
  • Scalability to support multiple 10/40G links using a clustering solution
  • Inspecting packets inside GRE, IPIP and MPLS tunnels
  • Deep packet inspection using our home made DPI engine called Phorcys
  • Sending detailed layer7 information about network flows using IPFIX and syslog protocol
  • Flexible and feature rich policy engine
    • subscriber based policy definition
    • supporting Accept, Drop, Reject, Rate limit, HTTP redirect, DNS redirect actions per flow
    • rule definition based on layer2 up to layer7 (e.g. HTTP host, URL, etc.) headers
    • A user friendly GUI for monitoring and policy definition
    • A RESTful API for monitoring and policy definition
