NETWORK CONVERGENCE
Network convergence is one of the main challenges of Next Generation Networks
Carrier-Grade Ethernet as transport technology of future network architectures
- Provider BridgesIEEE 802.1ad
- IEEE 802.1ah Provider Backbone Bridges
- IEEE 802.1Qay Provider Backbone Bridges - Traffic Engineering
- IEEE 802.1aq Shortest Path Bridging
Metro Ethernet Forum and Broadband Forum support this tendency
Virtualization Techniques
Click Project
- Basic modules to emulate PB, PBB & PBB-TE
- Design phase: C++ development reusability
Tap Devices
- Layer 2 virtual network devices
- Network connection virtualization between elements
- Originally developed at MIT
http://read.cs.ucla.edu/click/
Virtual Bridges
- Composed by basic Click elements and tap devices: .click files
- One Click process per element
Virtual Bridges GUI
New Graphical Tool developed
- Network scheme composition more efficient
- .click files consistence check & tap creation
- Source nodes and capture devices
- VNUML nodes
Bridging Virtualization
New approach for network convergence
- Multiple CGE instances onthe same element
- Packet classification based on VLANidentifier
- Output QoS support
Click development
- Based on modularity
- .click files change
- Forwarding processdepends on the specifictechnology

Best Features of Bridging Tool
Interaction between real and virtual devices
- Complex network architectures easily created
Wireshark sniffing abilities
- Available on every virtual/real port
- Real traffic between emulated elements
- Commercial products can be tested
- Virtual network can be split up in multiple machines
