It is my great pleasure to welcome you to the Eleventh ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS 2015). This year's conference will be held at the Oakland Marriott City Center in Oakland, CA, USA on May 7-8, 2015. In an important development, ANCS is this year co-located with the Twelfth USENIX Symposium on Networked Systems Design and Implementation (NSDI 2015) conference, something intended to become a regular feature to reduce travel expenses for those who attend both conferences.
This year's conference continues the tradition of ANCS in providing an opportunity for participants to exchange first-hand the cutting-edge system-oriented research results at the intersection of computer and network systems architecture from both academia and industry. We have an excellent program with 15 highquality papers, 15 posters, and two keynote presentations.
