“…Lastly, we note that this work extends an earlier workshop paper [15] in which we proposed a set of primitives for Internet measurement. We expand and generalize that work by defining a broader set of primitives, defining and implementing the Morpheme language and compiler, a run-time environment in Click, and conducting a set of experiments with these tools to demonstrate the feasibility of our approach.…”

Abstract-The vantage points of routers along end-to-end paths in the Internet have long made them a compelling target for additional functionality. In this paper, we describe a new method for router data plane programmability that is simple, general, flexible and safe and enables complex network services to be built and deployed. Our method targets network processor (NP)-and FPGA-based routers, and is based on two central ideas: (1) primitive functions for routers that are designed for specific target service domains, and (2) a primitive-aware programming language that is expressive, easy to use and easy to analyze. To demonstrate our method, we describe a set of primitive functions in the context of three diverse domains -network measurement, real-time applications and traffic engineering. Next, we describe Morpheme, our primitive-aware programming language, and show how it can be statically analyzed to safeguard router processor and memory resources. We demonstrate the efficacy of our method by implementing the primitive functions in the Click modular router [1] and a prototype Morpheme compiler. Through a series of microbenchmark experiments, we substantiate the capabilities of our prototype implementation.

Abstract-With an ever-increasing number of services being moved to cloud computing platforms, it is essential for data centre operators to quickly identify any problems in their network in order to ensure optimal performance and provide guidance for when actions such as migration of computing instances are required. This paper introduces a distributed measurement infrastructure using low-cost in-line link measurements to reveal the true traffic-perceived service quality in short timescales. In-line measurement is highly relevant for data centres as it allows an accurate measure of important network services without the problem of injecting artificial traffic into a network with high contention for resources. The infrastructure presented allows real-time monitoring and visualisation of the state of the network, which can be used to inform virtual machine migration/instantiation events. We show that the in-line measurements used by the infrastructure have negligible impact on network traffic and the hosts conducting the measurements. The low overhead of in-line measurements potentially enables the infrastructure to function as an always-on measurement and management platform.

Programmable optical networks are a key solution to high performance dynamic network services in Future Internet scenario. Modular router architecture which meets this concept is here defined and represented in a flexible software context, using Click! tools. Evaluation of logical performance and testing of physical characteristics of information forwarding within this framework is shown as feasible. The approach allows also to easily test functions and interactions of control and data planes to support enhanced future Internet services. Sample implementations of programmable router subsystems are given and discussed.
