DESCRIPTION:All traffic at Meta\, Cloudflare\, and many large companies ar
 e inspected\, optimized\, and balanced by tiny eBPF programs. Today\, the 
 eBPF ecosystem caters to the dominant open-source use cases\, i.e.\, debug
 ging (observability)\, and network functions (e.g.\, Firewalls\, and cloud
  networking). However\, a growing set of use cases within the enterprise a
 nd hyperscaler domains remain unaddressed. As a consequence\, eBPF program
 s in these programs are susceptible to significant performance and availab
 ility issues\, as evidenced by recent outages.\n\nIn this talk\, I will pr
 ovide a brief overview of these emerging use cases and the challenges they
  introduce. Then\, I will discuss recent work at Meta to generalize BPF-ma
 nagement heuristics by introducing mechanisms to decouple BPF management p
 rimitives from the kernel's heuristics. Finally\, I will describe ongoing 
 efforts to increase flexibility and reactivity by introducing a novel orch
 estration paradigm.\n\n\nBio: Theophilus A. Benson is a professor of Elect
 rical and Computer Engineering at Carnegie Mellon University. He earned hi
 s B.S. from Tufts\, Ph.D. from U of Wisconsin-Madison\, and post-doctorate
  from Princeton. Prof. Benson's research focuses on improving the performa
 nce and availability of computer networks. In particular\, he works with a
  broad set of cloud providers to improve their infrastructures. He has rec
 ently been developing an initiative to address the digital divide in the G
 lobal South. His research was recognized by paper awards\, including IMC\,
  EuroSYS\, ANRP. Dr. Benson received the SIGCOMM Test of Time Award\, NSF 
 CAREER Award\, NEC Faculty Award\, Google Faculty Award\, Facebook Faculty
  Award (X2)\, and Faculty Research and Engagement Program (X2). Prof. Bens
 on was recently named to DARPA's ISAT (Information Science and Technology)
  study group.\n
