Title: Method and apparatus for providing support for multiple qos levels within a third generation packet data session
Inventor: SEN SANJOY
IPC: H04L12/56
Filed: 2000-03-30
Abstract: A classification application utilizing a table of connection numbers and associated TCP/IP applications is utilized for determining a wireless packet communication, quality of service level by decoding a connection number field of the compressed packet header. Packets carrying different connection numbers can be mapped to different Quality of Service planes. When a non-active TCP connection becomes active, the classification application detects and identifies the connection by reading the connection number field of a compressed TCP/IP header in a packet of the application. The classification application applies the appropriate Quality of Service level as determined from a user database and a list of available Quality of Service levels. If the connection has no table entry, the TCP/IP application is identified based on comparison to a pre-loaded table of port numbers and a new entry is created in the connection number table.

Inventor: ROY BRIAN PAUL
IPC: D21C3/26
Filed: 2000-05-04
Abstract: Pulp is produced from wood or other lignocellulosic material by an improved kraft process in which the white liquor is introduced into the digester in at least two streams. A portion of the white liquor is used in an initial stage of the pulping process. Another portion of the white liquor is oxidized to convert reduced sulfur compounds in the white liquor to sodium thiosulfate and/or sodium sulfate, and this liquor is used during a later stage of the process. The benefits of using split sulfidity white liquor to produce pulp are realized by using a combination of white liquor and oxidized white liquor in the pulping process.
