“…The early systems include Smart Packets [32], ANTS [36], and PLAN [8], while more recent systems include PAN [28], SafetyNet [35], StreamCode [14], and SNAP [24]. Although these systems differ on many details of their design and implementation, they all support the basic AP model and thus the same general styles of evolution.…”

Evolution in Action: Using Active Networking to Evolve Network Support for Mobility

et al. 2002

Abstract.A key early objective of Active Networking (AN) was to support on-the-fly network evolution. Although AN has been used relatively extensively to build application-customized protocols and even whole networking systems, demonstrations of evolution have been limited. This paper examines three AN mechanisms and how they enable evolution: active packets and plug-in extensions, well-known to the AN community, and update extensions, which are novel to AN. We devote our presentation to a series of demonstrations of how each type of evolution can be applied to the problem of adding support for mobility to a network. This represents the most large-scale demonstration of AN evolution to date. These demonstrations show what previous AN research has not: that AN technology can, in fact, support very significant changes to the network, even while the network is operational.

“…APs and plug-in extensions have been well studied in AN research (e.g. [32,36,8,28,35,14,24,3,37,20,5,6]) but update extensions have not been explored for AN [12].…”

“…Yet despite this panoply of technical solutions, there is no widespread deployment of platforms supporting third party computation for networks or anything else 1 . We would argue that this situation exists because there is no benefit to the manager of any platform in supporting third party computation, and further, that there is no way for the manager to reflect the risk undertaken by hosting the platform.…”

Abstract. We believe that the problems of safety, security and resource usage combine to make it unlikely that programmable networks will ever be viable without mechanisms to transfer risk from the platform provider to the user and the programmer. However, we have well established mechanisms for managing risk -markets. In this paper we argue for the establishment of markets to manage the risk in running a piece of software and to ensure that the risk is reflected on all the stakeholders. We describe a strawman architecture for third party computation in the programmable network. Within this architecture, we identify two major novel features:-Dynamic price setting, and a reputation service. We investigate the feasibility of these features and provide evidence that a practical system can indeed be built. Our contributions are in the argument for markets providing a risk management mechanism for programmable networks, the development of an economic model showing incentives for developing better software, and in the first analysis of a real transaction graph for reputation systems from an Internet commerce site.

“…Some are built with only a specific range of services in mind (for example, network management [2,3], signalling [4], and multicast [5,6]), while others fail to provide the necessary flexibility or extensibility to dynamically deploy new types of services, which have not been considered by the developers (for example, Scout [7], Click [8] and RouterPlugins [9]). Yet, the most neglected requirement in today's active router architectures is support for service composition enabling the installation and management of diverse services by independent users who may be unaware of each other.…”

Active Routers in Action: Evaluation of the LARA++ Active Router Architecture in a Real-Life Network

et al. 2004

Abstract. The paper reports on lessons learned from developing, deploying and operating LARA++ based active routers [1] along with a number of active services used daily in a real-life network environment. We evaluate how LARA++, which claims to be a truly generic and flexible active router architecture, performs when deployed in an operational network. The architecture is assessed whilst providing a range of diverse active services from well-known network services like NAT and firewalls to novel types of services such as Mobile IPv6 handoff optimisation. A particular challenge we consider is the transparent and concurrent introduction of new services by different end users and network administrators. Besides a qualitative evaluation of the LARA++ architecture, the paper provides a number of quantitative results that show the performance of LARA++ whilst providing the different services. The results indicate that LARA++ not only supports highly generic programmability by independent users, but also provides sufficient performance for today's edge networks.
