shortcut links. We propose its adaptation to Ethernet, using a new type of hierarchical Ethernet addresses and a procedure to assign them to bridges. We show that compared to RSTP, TRE offers improved throughput. The impact of transient loops in TRE is lower compared to the application of the classical shortest path routing protocols to Ethernet. Finally,(More)
In this note, we propose a security mechanism for protecting IPv6 networks from possible abuses caused by the malicious usage of a multihoming protocol. In the presented approach, each multihomed node is assigned multiple prefixes from its upstream providers, and it creates the interface identifier part of its addresses by incorporating a cryptographic(More)
Ethernet switched networks do not scale appropriately due to limitations inherent to the spanning tree protocol. Ethernet architectures based on routing over a virtual topology in which turns are prohibited offer improved performance over spanning tree, although in some cases suffer from excessive computational complexity. Up/Down routing is a turn(More)
This paper proposes a scalable solution for the support for globally moving networks. It is basically oriented to airborne mobile networks built in commercial aircrafts in order to provide Internet access to the passengers. As opposed to currently used solutions, the proposed solution has no impact in the global routing tables while it provides optimized(More)
—We claim that the slow deployment of IPv6 seen so far is related with the complete decoupling with IPv4 regarding to routing and addressing. In this paper we propose Integrated Routing and Addressing (InRA), a new solution to allow IPv6 to integrate with IPv4 routing and addressing in order to decrease management cost during the coexistence period, and(More)
In this paper we propose Fast Path Ethernet, an evolution of the transparent bridges learning mechanisms to increase infrastructure utilization for campus and datacenter networks in a simple way. Fast Path Ethernet Switches reuse standard ARP Request and Reply packets to set up fast on-demand paths between hosts. This architecture uses the standard Ethernet(More)
