The growth of the internet has been fueled by an increasing number of sophisticated network-accessible services. Unfortunately, the high bandwidth and processing requirements of such services is at odds with current trends towards increased variation in network characteristics and a large diversity in end devices. Ubiquitous access to such services requires the injection of additional functionality into the network to handle protocol conversion, data transcoding, and in general bridge disparate portions of the physical network. Several researchers have proposed infrastructures for injecting such functionality; however, many challenges remain before these infrastructures can be widely deployed. CANS is an application-level infrastructure for injecting application-specific components into the network that focuses on three such challenges: (a) efficient and dynamic composition of individual components; (b) dynamic and distributed adaptation of injected components in response to system conditions; and (c) support for legacy applications and services. The network view supported by CANS consists of applications, stateful services, and data paths between them built up from mobile soft-state objects called drivers. Both services and data paths can be dynamically created and reconfigured: a planning and event propagation model assists in distributed adaptation, and a run-time type-based composition model dictates how new services and drivers are integrated with existing components. An interception layer that virtualizes network bindings permits legacy applications to plug into the CANS infrastructure, and a delegation model does the same for legacy services. This paper describes the CANS architecture and implementation, and a case study involving a shrink-wrapped client application in a dynamically changing network environment where CANS was used to improve overall user experience. |
