The 5-layer TCP and 7-layer OSI models are taught as high-level frameworks in which the various protocols that are used in computer networks operate.These models provide valid insights in the organization of network functionalities and protocols; however, the difficulties to fit some crucial technologies within them hints that they don't provide a complete model for the organization of -and relationships between -different mechanisms in a computer network.Recently, a recursive model for computer networks was proposed, which organizes networks in layers that conceptually provide the same mechanisms through a common interface. Instead of defined by function, these layers are distinguished by scope.We report our research on a model for computer networks. Following a rigorous regime alternating design with the evaluation of its implications in an implementation, we converged on a recursive architecture, named Ouroboros. One of our main main objectives was to disentangle the fundamental mechanisms that are found in computer networks as much as possible. Its distinguishing feature is the separation of unicast and broadcast as different mechanisms, giving rise to two different types of layers. These unicast and broadcast layers can easily be spotted in today's networks.This article presents the concepts underpinning Ouroboros, details its organization and interfaces, and introduces the free software prototype. We hope the insights it provides can guide future network design and implementation.

SUMMARYThe identifier/locator separation has been widely recognized as a feasible solution for addressing the current Internet's routing scaling problem. Moreover, such a separation solution in terms of mobility can keep connection survivability and support global seamless roaming. A critical challenge in supporting efficient mobility is how to update the identifier‐to‐locator mappings of mobile nodes (MNs). In this paper, we propose a mapping forwarding (MF) scheme for location management in the identifier/locator separation architecture. In the MF scheme, a tunnel router (xTR) is selected as an agent of an MN and keeps the MN's identifier‐to‐locator mapping invariable by setting up an MF chain. As long as the MN is managed by the same xTR, the MN's mapping stored in the xTR of each correspondent node of the MN does not need to be updated, thus reducing the location update signaling cost. Meanwhile, the unchanged mapping assures the correct forwarding of packets, which reduces mobility‐related disruption and enhances the location management's reliability. In addition, for the handoff in two MF chains, we propose a data‐triggered update scheme that can achieve route optimization. To evaluate the proposed MF scheme, we establish two analytical models and formulate the blocking probability and the total protocol cost. The performance results show how the blocking probability changes under various parameters and how the MF scheme can effectively reduce the blocking probability compared with the location management scheme without the MF strategy. Meanwhile, our analysis demonstrates that the MF scheme has a lower overhead when the mobility rate is high. Copyright © 2011 John Wiley & Sons, Ltd.
