WANem is a Wide Area Network Emulator, meant to provide a real experience of a Wide Area Network/Internet, during application development / testing over a LAN environment. Typically application developers develop applications on a LAN while the intended purpose for the same could be, clients accessing the same over the WAN or even the Internet.
However, as noted by Hitesh this kind of setup should be avoided because WAN routers have much less forwarding capabilities then LAN switches and because broadcast traffic will consume WAN bandwidth. Some use of this is seen in some disaster recovery designs that ask for extending selected Vlans between central site and disaster recovery site. State of the WAN: 50% of WAN traffic is in the cloud Aryaka’s 2017 State of the WAN report shows the cloud era has arrived in a big way, making SD-WANs business-critical. Companies must adopt this An SD-WAN policy rule references a Traffic Distribution profile to distribute sessions and to fail over to a better path when path quality deteriorates. Based on your SD-WAN configuration plan, create the SD-WAN Traffic Distribution Profiles you need based on how you want the applications in your SD-WAN policy rules to be session loaded and to Importantly, TeaVaR, which optimizes how user traffic is split across network tunnels, can be coupled with any scheme for WAN tunnel selection, including oblivious routing, k-shortest paths, and link-disjoint routes. We also show that our optimization is fairly robust to inaccuracies in failure probability estimations. Not only can you optimize your WAN traffic, you can achieve the highest level of WAN redundancy and reliability. Additionally, unlike other WAN optimization/acceleration products that provide WAN caching at the file level, FatPipe WAN caching works at the file as well as the byte level.
Web traffic is another common type of traffic that a network administrator may wish to optimize or control. This branch will leverage a PbR rule to send web traffic over VPN tunnels formed on the WAN 1 interface, but only if that matches a custom-configured performance class.
I am saying that you have no assurance that it hasn't been snooped on by anyone, hence, the need for encrypting the traffic before it hits the WAN. This should be standard operating procedure, but I still hear from IT admins in different verticals and different size companies who transmit potentially sensitive data unencrypted over the carrier SNMP to monitor the routers traffic on the WAN ports, coupled with network monitor mapping software like TheDude to create nice visual representation of links with current utilisation. (As a bonus The Dude changes the link color as the utilization increases towards its capacity)
WANEM : The Wide Area Network Emulator
What is WAN Optimization (WAN Acceleration)? WAN optimization -- also known as WAN acceleration -- is the category of technologies and techniques used to maximize the efficiency of data's flow across a wide area network (), between organizations' centralized data centers and their remote locations.In an enterprise WAN, the goal of optimization is to increase the speed with which end users can access business-critical applications and Traffic shaping - Wikipedia Traffic shaping is a bandwidth management technique used on computer networks which delays some or all datagrams to bring them into compliance with a desired traffic profile. Traffic shaping is used to optimize or guarantee performance, improve latency, or increase usable bandwidth for some kinds of packets by delaying other kinds. It is often confused with traffic policing, the distinct but Best Network Traffic Generator Software & Tools for WAN WAN Killer Network Traffic Generator.
