Reservation-based quality of service (QoS) in a mixed wireless and wireline environment requires an end-to-end signaling protocol that is capable of adapting to the idiosyncrasies of the different networks. The QoS NSIS signaling protocol (QoS-NSLP) has been created by the Next Steps In Signaling working group at the IETF to fulfill this need for an(More)
This paper discusses the motivation for developing a new QoS sig-naling protocol for IP-based Radio Access Networks. It describes the main characteristics of these networks and the special requirements imposed by these characteristics on QoS signaling solutions. Due to its flexibility and cost efficiency, IP transport is gradually introduced in different(More)
Alkali-cation-dependent uptake of proline and glycine into brush-border membrane vesicles from the midgut of the larval tobacco hornworm Manduca sexta was investigated using rapid filtration assays. Uptake of both amino acids was by electrophoretic symport, with K+ being the favored cation at pH 10. Counterflow accumulation of proline was elicited by(More)
