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.

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.

7. 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. - View Dependent Claims (8, 9, 10, 11, 12)
