  Humkinar Ad-exchange system provides an opportunity to the advertisers to reach users through advertisements on the Humkinar Urdu search engine. Our system intelligently and automatically matches the needs of users and advertisers to display the advertisement to the users.
  

• RouterLab
  The Routerlab is a router centric, customizable testbed that reflects the macroscopic structure of the Internet, with different clouds and tier levels and simulation of differing access properties via network emulation. This, in combination with a flexible traffic generation framework, enables students to conduct Internet-level experiments on a small scale, within the borders of the server room.
  

• LabTool
  Routerlab's management platform called Labtool supports heterogeneous hardware landscapes and user groups (e.g., labcourse student teams, individual researchers working on differing layers, developers). To accommodate the span of differing requirements of these user groups, it offers both virtualized and bare-metal, non-virtualized resources and can support versioned, controlled changes to the physical topology.
  

• QoE-Lab
  A multi-purpose heterogeneous testbed that supports a variety of networking conditions to evaluate QoE in future Internet scenarios. QoE-Lab includes 1) NGMN networks, 2) access/backbone network emulation, and 3) virtualization. It provides services like traffic generation, topology emulation and high-precision cross-layer monitoring. The experiments are provisioned, orchestrated and analyzed by a tool called ExpAuto.
