Abstract

The present invention is directed to the use of a messaging component for sharing a common network communication channel by a plurality of threads of execution. The messaging component receiving a message and forwarding the message to one or more of the threads using information in a payload portion of the message, which is compared with supplied registration information. In addition, according to the present invention, messaging and job components may be used by each of a plurality of execution threads to negotiate a manner of transferring data between two network computers, wherein the job component proposes a manner of transfer, which is communicated using the messaging component to a receiving a computer. The proposed manner of transfer may be accepted or rejected by the receiving computer. An alternative manner of transfer may be proposed, where another manner of transfer is found to be unacceptable.

Claims

1. A method for transferring job data in a digital cable network system wherein the digital cable network system includes a sending component and a receiving component which communicate over the network, the method comprising:

determining, at the sending component, a manner of transfer which is selected from a group consisting of all of (i) a referential transfer using a secure pipe, (ii) a referential transfer not using a secure pipe, (iii) a direct transfer using a secure pipe, and (iv) a direct transfer not using a secure pipe,

wherein, in the referential transfer, the sending component uploads the job data to a predetermined location on a secure server, and the sending component sends location information corresponding to the secure server to the receiving component, and the uploaded job data is received by the receiving component from the predetermined location on the secure server, wherein the uploaded job data is received in accordance with a request which includes the location information from the receiving component;

transferring, from the sending component to the receiving component, a message which includes the determination result of the determining step;

uploading the job data from the sending component to a predetermined location on a secure server, responsive to a determination of the determining step that the manner of transfer is (i) a referential transfer using a secure pipe or (ii) a referential transfer not using a secure pipe;

transferring the job data from the sending component to die receiving component via direct communication responsive to a determination of the determining step that the manner of transfer is (iii) a direct transfer using a secure pipe or (iv) a direct transfer not using a secure pipe;

wherein when the determining step determines that the manner of transfer is (i) a referential transfer using a secure pipe or (iii) a direct transfer using a secure pipe, said transferring step and said uploading step control communication by using a secure socket layer protocol; and

wherein the job data uploaded by the uploading step is received by the receiving component in accordance with the request from the receiving component when the manner of transfer is determined (i) or (ii) in which the referential transfer is used.

2. The method according to claim 1, wherein said uploading step further encrypts the data itself before uploading via a secure socket layer.

3. A sending component operating in a cable head end (CHE) which communicates over a network to transfer job data to a receiving component operating in a set top box (STB) in a digital cable network system, comprising:

a determining unit constructed to determine, at the sending component, a manner of transfer which is selected from a group consisting of all of (i) a referential transfer using a secure pipe, (ii) a referential transfer not using a secure pipe, (iii) a direct transfer using a secure pipe, and (iv) a direct transfer not using a secure pipe,

wherein, in the referential transfer, the sending component uploads the job data to a predetermined location on a secure server, and the sending component sends location information corresponding to the secure server to the receiving component, and the uploaded job data is received by the receiving component from the predetermined location on the secure server, wherein the uploaded job data is received in accordance with a request which includes the location information from the receiving component;

a transferring unit constructed to transfer, from the sending component to the receiving component, a message which includes the determination result;

an uploading unit constructed to upload the job data from the sending component to a predetermined location on a secure server, responsive to a determination of the determining unit that the manner of transfer is (i) a referential transfer using a secure pipe or (ii) a referential transfer not using a secure pipe;

transferring unit constructed to transfer the job data from the sending component to the receiving component via direct communication responsive to a determination of the determining unit that the manner of transfer is (iii) a direct transfer using a secure pipe or (iv) a direct transfer not using a secure pipe;

wherein when the determining unit determines that the manner of transfer is (i) a referential transfer using a secure pipe or (iii) a direct transfer using a secure pipe, said transferring unit and said uploading unit control communication by using a secure socket layer protocol; and

wherein the job data uploaded by the uploading unit is received by the receiving component in accordance with the request from the receiving component when the manner of transfer is determined (i) or (ii) in which the referential transfer is used.

4. The apparatus according to claim 3, wherein said uploading unit further encrypts the data itself before uploading via a secure socket layer.

5. A computer-readable storage memory medium having computer-executable process steps stored thereon for transferring job data in a digital cable network system, wherein the digital cable network system includes a sending component and a receiving component which communicate over the network, wherein said process steps comprise:

a determining step to determine, at the sending component, a manner of transfer which is selected from a group consisting of all of (i) a referential transfer using a secure pipe, (ii) a referential transfer not using a secure pipe, (iii) a direct transfer using a secure pipe, and (iv) a direct transfer not using a secure pipe,

wherein, in the referential transfer, the sending component uploads the job data to a predetermined location on a secure server, and the sending component sends location information corresponding to the secure server to the receiving component, and the uploaded job data is received by the receiving component from the predetermined location on the secure server, wherein the uploaded job data is received in accordance with a request which includes the location information from the receiving component;
