Abstract

An apparatus and method are described for supporting a plurality of connections between a client computer and a network server. The client computer supports a plurality of simultaneously logged on ("active") services. The client computer creates a connection for each set of distinct credentials supplied by services logged onto the client computer. The client computer includes a redirector for maintaining independent control, status and data information for a plurality of independent connections associated with the plurality of simultaneously active services having distinct sets of credentials.

Claims

1. A computer network comprising:

communications facilities connecting a network server to at least one client computer;

two or more networked services simultaneously supported by the client computer;

a redirector resident in the client computer for simultaneously supporting two or more connections over the communications facilities between the client computer and the network server, at least two of the connections each having a separate network credential and supporting at least two networked services.

2. The computer network of claim 1 wherein the redirector comprises means for maintaining information for the simultaneous connections.

3. The computer network of claim 2 wherein the means for maintaining information includes a connection status database for storing independent control information blocks, the independent control information blocks comprising server control blocks, and each server control block corresponds to one of the simultaneous connections.

4. The computer network of claim 3 wherein the independent control information blocks further comprise file control blocks linked to the server control blocks, and wherein each file control block specifies a file accessed through one of the simultaneous connections corresponding to one of the linked server control blocks.

5. The computer network of claim 1 wherein the client computer maintains a set of sockets for each one of the simultaneous connections.

6. The computer network of claim 1 wherein the network credentials associated with one of the simultaneous connections comprise a logon name and a password supplied by one of the networked services.

7. The computer network of claim 1 wherein the client computer further comprises a security system for receiving the network credentials from at least two of the networked services and assigning a unique identifier to each of these networked services in association with a logon procedure.

8. The computer network of claim 1 wherein the client computer comprises a program manager simultaneously supporting two or more networked services.

9. The computer network of claim 1 wherein the client computer further comprises a security system for receiving the network credential from one of the networked services and assigning a unique identifier to the corresponding connection in association with a logon procedure.

10. The computer network of claim 1 wherein at least two of the simultaneous connections between the client computer and the network server are made using Netware Core Protocol (NCP).

11. The computer network of claim 1 wherein one of the networked services is remote file sharing.

12. The computer network of claim 11 wherein the network server is a file sharing server.

13. The computer network of claim 12 wherein the network server is a Netware Core Protocol (NCP) file sharing server.
