Leveraging network performance with IPv6 multihoming and multiple provider-dependent aggregatable prefixes
Computer Networks, 2006Co-Authors: Cédric De Launois, Bruno Quoitin, Olivier BonaventureAbstract:Multihoming, the practice of connecting to multiple providers, is becoming highly popular. Due to the growth of the BGP routing tables in the Internet, IPv6 multihoming is required to preserve the scalability of the interdomain routing system. A proposed method is to Assign multiple provider-dependent aggregatable (PA) IPv6 prefixes to each site, instead of a single provider-independent (PI) prefix. We show that the use of multiple PA prefixes not only allows route aggregation but also can be used to reduce end-to-end delays by leveraging the Internet path diversity. We quantify the gain in path diversity, and show that a dual-homed Stub As that uses multiple PA prefixes hAs already a better Internet path diversity than any multihomed Stub As that uses a single PI prefix, whatever its number of providers. The benefits provided by the use of IPv6 multihoming with multiple PA prefixes are an opportunity to develop the support for quality of service and traffic engineering.

coplanar waveguide bandpAss filter a ribbon of brick wall design
IEEE Transactions on Microwave Theory and Techniques, 1995Co-Authors: Fanglih Lin, Chienwen ChiuAbstract:This paper proposes a novel ribbon-of-brick-wall design of the coplanar waveguide bandpAss filter which is built from cAscading several sections of quarter wavelength open-end series Stubs. The design originates from modeling the series Stub As a system of two Asymmetrically coupled transmission lines, which is then made equivalent to a bAsic filter element of admittance inverter. The relationship between the parameters of the coupled transmission lines and the admittance inverter is derived and the design charts are provided for the convenience of the designers. Systematic procedure is established to design the Chebyshev filter, which is also fabricated and meAsured. In addition, the quAsistatic equivalent lumped circuit models of the discontinuities formed between two sections are evaluated and incorporated into the circuit simulation to get better prediction for the filter performance. The good agreement between simulation results and experimental data justifies the design procedure and validates the present analysis approach. >
