Today’s Priority Queue returns to the IETF to explore the concept of path-aware networking. Currently, end points on a network have little control over or information about the path over which their traffic is carried.
Efforts are under way, both by vendors and within standards bodies, to develop technologies and protocols to both provide more information about links (i.e. performance, trust, cost, and so on) and enable end points to select the most appropriate path to meet certain criteria.
For example, SD-WAN gateways can connect to multiple links and then direct traffic across one or more of those links based on customer-defined policies.
Greg Ferro and guests from the IETF’s Path Aware Networking Research Group discuss the concepts of path aware networking and examine the work being done by the group.
Our guests are Brian Trammell, co-chair of the Path Aware Networking Research Group and a researcher at ETH Zurich; and Jen Linkova, also a co-chair of the research group and a network engineer at Google.
Thanks to Huawei, which covered travel and accommodations to enable the Packet Pushers to attend IETF 99 and record some shows to spread the news about IETF projects and initiatives.
