Stream distribution system and failure detection method
First Claim
1. A stream distribution system, comprising:
- a first stream distribution server for communicating with a client terminal via a network apparatus and sending stream data; and
a second stream distribution server configured as a redundant server of the first stream distribution server and connected to the first stream distribution server;
wherein the first stream distribution server includes;
a send unit configured to send communication information concerning the communication with the client terminal to the second stream distribution server; and
wherein the second stream distribution server includes;
an acquisition unit configured to acquire mirror data, which is a copy of data sent to the first stream distribution server, from the network apparatus; and
a network failure detection configured to detect a failure in a network between the first stream distribution server and the client terminal based on the communication information and the mirror data,wherein the second stream distribution server further includes an analysis unit configured to analyze a failure in the network when a failure is detected in the network.

Abstract
Provided are a stream distribution system and a failure detection method capable of easily identifying the cause of quality loss in stream distribution. This stream distribution system includes a first server for communicating with a client terminal via a router and sending stream data, and a second server configured as a redundant server of the first server and connected to the first server. The first server has a communication status notification unit for sending a connection management table concerning the communication with the client terminal to the second server. The second server has a packet recording unit for acquiring a mirror packet, which is a copy of a packet sent to the first server, from the router, and a network failure monitoring unit for detecting a failure in a network between the first server and the client terminal based on the connection management table and a packet buffer.

6. A failure detection method for use in a system including a first stream distribution server for communicating with a client terminal via a network apparatus and sending stream data, and a second stream distribution server configured as a redundant server of the first stream distribution server and connected to the first stream distribution server, comprising:
-
a send step of the first stream distribution server sending communication information concerning the communication with the client terminal to the second stream distribution server; an acquisition step of the second stream distribution server acquiring mirror data, which is a copy of data sent to the first stream distribution server, from the network apparatus; and a network failure detection step of the second stream distribution server detecting a failure in a network between the first stream distribution server and the client terminal based on the communication information and the mirror data, wherein the network failure detection step further includes an analytical step of the second stream distribution server analyzing a failure in the network when a failure is detected in the network. - View Dependent Claims (7, 8, 9, 10)
