Google Tech Talk (more below) March 3, 2011 Presented by Prof. Fernando Pedone, University of Lugano. ABSTRACT Atomic broadcast is an important communication primitive often used to implement state-machine replication. Despite the large number of atomic broadcast algorithms proposed in the literature, few works have discussed how to turn these algorithms into efficient executable protocols. Our...

Anycast Routing is used on the Internet to provide many services, including NTP and DNS, but very few know that you can locally deliver websites and content over HTTP/TCP/Anycast. There's many factors that go into designing an anycasted network. We'll discuss a real world event on Dyn Inc's network which caused a severe service degradation for one of our nameservers due to uncontrolled anycast ...

Many systems that speak over TCP have simple call-and-response protocols. These lend themselves well to extracting reasonably accurate request and response start and end times. This is a fabulously rich source of data that can be mined for many types of purposes. All that is needed is the first 384 bytes of each packet, containing IP and TCP headers but no payload. This is simple and non-intrus...

Google Tech TalkFebruary 10, 2010ABSTRACTPresented by Dino Farinacci.We will describe the initial problem statement LISP was created for. Since fall of 2006, when the IAB held a routing workshop in Amsterdam, we have found many more use cases for the level of indirection LISP brings. LISP is taking the overloaded semantics of the IP address, where a network device's identity address and locatio...

Google Tech TalkFebruary 17, 2010ABSTRACTPresented by Dino Farinacci.In Part 1, we discussed how endpoint IDs and routing Locators are used to provide a level of indirection for routing and addressing. This session will describe all the database mapping algorithms we have considered for mapping an EID to a set of Locators. We will take about the technical challenges of each and brainstorm about...

Google Tech TalkFebruary 24, 2010ABSTRACTPresented by Dino Farinacci.Now that Part 1 and Part 2 sessions gave you the foundation of the technology, we will take a deep-dive of the various use-cases LISP provides. From low opex multi-homing to using provider independent addresses to Data Center to Mobility applications, we will show how one architectural solution can solve so many critical probl...
