We present our design, implementation, and experience with OCALA, an overlay convergence architecture that achieves this goal. OCALA interposes an overlay convergence layer below the transport layer. This layer is composed of an overlay independent sub-layer that interfaces with legacy applications, and an overlay dependent sub-layer that delivers packets to the overlay. Unlike previous efforts, OCALA enables: (a) simultaneous access to multiple overlays (b) communication between hosts in different overlays (c) communication between overlay hosts and legacy hosts (d) extensibility, allowing researchers to incorporate their overlays into OCALA. We currently support five overlays, i3 [32], RON [1], HIP [19], DOA [39] and OverDoSe [31] on Linux, Windows XP/2000 and Mac OS X. We (and a few other research groups and end-users) have used OCALA for over a year with many legacy applications ranging from web browsers to remote desktop applications.}, note = {San Jose, California}, publisher = {USENIX / ACM}, booktitle = {Proceedings of 3rd ACM Sigcomm/ACM Sigops Symposium on Networked Systems Design and Implementation (NSDI 2006)}, organization = {ACM}, author = {Joseph, Dilip A and Lakshminarayanan, Karthik and Stoica, Ion and Wehrle, Klaus} } @Inproceedings { 200410acmmultimediai3composition, title = {Support for Service Composition in i3}, year = {2004}, url = {http://i3.cs.berkeley.edu}, address = {New York, USA}, booktitle = {Proceedings of ACM Multimedia 2004}, organization = {ACM}, author = {Lakshminarayanan, Karthik and Stoica, Ion and Wehrle, Klaus} } @Techreport { 200606i3proxytechreport, title = {Supporting Legacy Applications over i3}, year = {2004}, number = {UCB/CSD-04-1342}, abstract = {Providing support for legacy applications is a crucial component of many overlay networks, as it allows end-users to instantly benefit from the functionality introduced by these overlays. This paper presents the design and implementation of a proxy-based solution to support legacy applications in the context of the i3 overlay [24]. The proxy design relies on an address virtualization technique which allows the proxy to tunnel the legacy traffic over the overlay transparently. Our solution can preserve IP packet headers on an end-to-end basis, even when end-host IP addresses change, or when endhosts live in different address spaces (e.g., behind NATs). In addition, our solution allows the use of human-readable names to refer to hosts or services, and requires no changes to applications or operating systems. To illustrate how the proxy enables legacy applications to take advantage of the overlay (i.e., i3) functionality, we present four examples: enabling access to machines behind NAT boxes, secure Intranet access, routing legacy traffic through Bro, an intrusion detection system, and anonymous web download. We have implemented the proxy on Linux andWindows XP/2000 platforms, and used it over the i3 service on PlanetLab over a three month period with a variety of legacy applications ranging from web browsers to operating system-specific file sharing.}, url = {http://i3.cs.berkeley.edu}, address = {UCB, Berkeley, USA}, institution = {University of California at Berkeley}, type = {Technical Report}, author = {Kannan, Jayanthkumar and Kubota, Ayumu and Lakshminarayanan, Karthik and Stoica, Ion and Wehrle, Klaus} }
