The ACM 8th international conference on emerging Networking EXperiements and Technologies (CoNEXT) was or- ganized in a lovely hotel in the south of France. Although it was in an excellent location in the city center of Nice with views to the sea, it suffered from poor Internet connectivity. In this paper we describe what happened to the network at CoNEXT and explain why Internet connectivity is usually a problem at small hotel venues. Next we highlight the usual issues with the network equipment that leads to the general network dissatisfaction of conference attendees.

During the last decade, we have seen the rise of discussions regarding the emergence of a Future Internet. One of the proposed approaches leverages on the separation of the identifier and the locator roles of IP addresses, leading to the LISP (Locator/Identifier Separation Protocol) protocol, currently under development at the IETF (Internet Engineering Task Force). Up to now, researches made on LISP have been rather theoretical, i.e., based on simulations/emulations often using Internet traffic traces.

The Internet operator and research communities have been lamenting the increase in BGP routing table entries and increase in churn for some time now. Many solutions have been proposed, but few have been deployed. This paper looks at the operational deployment of the Locator/ID Separation Protocol, or LISP. LISP is a protocol that separates two functions of IP addresses -- identifying a communication endpoint, and locating where it is connected to the Internet. This provides flexibility in sending traffic to an endpoint via different connection points or routes, while managing the traditional problems of routing table bloat and churn. As can be seen on the lisp4.net website, the current LISP topology includes over a hundred tunneling routers and a large number of endpoint prefixes. This paper explains LISP, gives an overview of the current deployment, and examines how the performance of LISP has changed over time. The deployment of LISP is still in its early stages and it is premature to do an in-depth research study on it. However, the reviewers agree that this paper provides value to the community as an introduction to the protocol and statistics on the current deployment. The authors have worked diligently with the reviewers to improve their paper.
