In "Corporate Networks" we use a laboratory scenario based on Linux+Traffic Control, which allows expermientation with several QoS mechanisms: Traffic shaping. Traffic policing. Traffic scheduling. The scenario is shown below: Two customer edge devices (CE1, CE2) can communicate through a service provider offering Ethernet connectivity. In order not to complicate the scenario, CE1 behaves as an end user device running […]

The MetroEthernet Forum (MEF) produces the MetroEthernet service specifications. These specifications include bandwidth profiles and policing. Recent versions of the bandwidth profiles are increasingly complex, but in their simplest configuration they can be described as a double token bucket. Here I will briefly describe the basic operation of this mechanism. The interested reader can further explore the […]

Virtual Private LAN Service (VPLS) is studied in Redes Corporativas (4º year of GIST). For teching and learning VPLS it is veri useful to have virtualized network scenarios. For virtualization of network scenarios, the Virtual Networks over LinuX (VNX) tool has been developed at DIT-UPM. VNX allows deploying of virtual machines running a variety of platforms and operating systems. […]
