Patent CA-2260988-A1 (CA)
Inventor: SAITOH KAZUYA
IPC: C03C13/04
Filed: 1997-07-14
Abstract: This ultralow-loss glass is characterized in that high purity silica glass contains 1 to 500 wt.ppm of at least one network modifying oxide. It is assumed that the network modifying oxide appropriately loosens the tetrahedral network structure of silica and hence Rayleigh scattering is decreased. Examples of the network modifying oxide include Na 2 O, K 2 O, Li 2 O, MgO, CaO, and PbO. Since Rayleigh scattering losses are minimal in comparison with these of high purity silica glass, this impurity-added silica glass is excellent as a base material of a glass fiber for a long-distance transmission.

Title: Method and apparatus for controlling traffic flows in a packet-switched network
Inventor: PEZESHKI-ESFAHANI HOSSAIN
IPC: H04Q11/04
Filed: 1999-02-03
Abstract: A scheduling device for use in a packet-switched network, belonging to the class of non-work conserving or idling weighted round robin (WRR) arbiters, assigns a packet stream slots in a fixed-length time division multiple access (TDMA) frame by selecting free slots which are closest to ideal slot positions that would, if assigned, eliminate fitter or cell delay variation. The scheduler is able to simultaneously determine if a new constant bit rate connection requiring a predetermined bandwidth conforms to a leaky bucket or GCRA  algorithm characterized by a peak packet or cell emission interval T=1/PCR and a packet or cell delay variation time, CDVT, i.e., whether the new connection is GCRA(T, CDVT) conformant. This determination is made by comparing the quantity ME + ML against the CDVT, where ME corresponds to the maximum time or distance by which any assigned slot is earlier than a corresponding ideal slot and ML corresponds to a maximum time or distance by which any assigned slot is later than a corresponding ideal slot. The scheduler can thus also carry out connection admission control (CAC) functions in an ATM network switch.
