Today’s interdomain routing protocol, Border Gateway Protocol (BGP) [9], scales well but suffers from two significant shortcomings. First, does not provide high availability in the event of failures or changes in network conditions (i.e., it converges slowly). Second, BGP is insecure: it provides little to no protection against malicious parties who can inject incorrect or misleading routing in...

The use of forward error correction (FEC) coding is often proposed to combat the effects of network packet losses for error-resilient video transmission on packet-switched networks. On the other hand, path diversity has recently been proposed to improve network transport for both singledescription (SD) and multiple-description (MD) coded video. In this work we model and analyze an SD coded vide...

We study the performance of TCP-based media transport when combined with packet path diversity (PPD) in the Internet. We present a simple PPD-TCP transmission scheme where the acknowledgments (ACKs) from the receiver are duplicated and sent across independent network paths. We also investigate a PPD-TCP scheme where in addition to path-diversified ACKs on the backward path, packet path diversit...

When considering many paths in a multihop wireless setting, the variability of channels results in some paths providing better performance than other paths, i.e., path diversity. While it is well known that some paths are better than others, a significant number of routing protocols do not focus on selecting the optimal path. However, cooperative diversity, an area of recent interest, provides ...

Path Diversification is a new mechanism that can be used to select multiple paths between a given ingress and egress node pair using a quantified diversity measure to achieve maximum flow reliability. The path diversification mechanism is targeted at the end-to-end layer, but can be applied at any level for which a path discovery service is available. Path diversification also takes into accoun...

In this paper, we argue that the metaphor form of a comparison (i.e., a topic-vehicle pair) is preferred over, and more comprehensible than, the simile form when the interpretive diversity for that comparison is high. Interpretive diversity refers to the richness of the figurative meaning of a comparison; it is high to the extent that more features or properties are related to the figurative me...

This phenomenological qualitative study examined the experiences of graduate-level teacher candidates enrolled in residency programs and serving as aides or assistants (TAs). Some participants were already employed TAs a large urban district an Urban Pipeline Residency Program, state-funded diversity initiative designed to increase number teachers from underrepresented groups by supporting purs...
