The World Telecommunication Standardization Assembly (WTSA) is held every four years with the aim of helping define the next period of study for the ITU Telecommunication Standardization Sector (ITU-T). As preparations continue, I want to give a quick update on what has – or more importantly what hasn’t – changed for New IP in the lead up to WTSA-20.
As discussed in a recent blog, the bridged overlay model does not provide a mechanism for inter-VXLAN routing functionality within the fabric. Depending on your requirements, this may be sufficient – or even desired. However, if you want routing to happen within the fabric you need to consider another option.
If you want to get a sense of what is happening in the high-end of the Ethernet switch and routing market, it is Arista Networks, formerly an upstart and now just one of the bigger vendors taking on the hegemony of Cisco Systems in networking in the datacenter and now on the campus and at the edge, is probably the best bellwether there is. And so, we like to keep an eye on what Arista is up to.
