Communication quality management and apparatus
First Claim
1. A communication quality management method of multicasting data from a distribution server to reception terminals via a router connected to a network, the method comprising:
- receiving a multicast packet from the distribution server;
adding quality information to the multicast packet;
retransmitting the multicast packet with the added quality information via the router;
removing the quality information from the multicast packet by a reception terminal proxy coupled between each corresponding reception terminal and the router;
performing quality information calculations and data processing by the reception terminal proxy;
transferring the processed quality information from each reception terminal proxy to an accumulation server coupled to the router;
accumulating the transferred quality information in a database; and
distributing, to the reception terminal, the multicast packet from which the quality information is removed.

Abstract
A server proxy (12), which is arranged between a distribution server (11) and a router (13a), adds quality information to a packet (19a) from the distribution server (11) to output a packet (19b). A plurality of reception terminal proxies (17a-17n), which are arranged immediately before respective reception terminals (18a-18n), remove the quality information from the packet (19b) distributed via a network (14) and routers (13b-13m), and distribute only necessary information to the respective reception terminals (18). Each reception terminal proxy (17) which includes a quality information acquisition unit (17A) acquires the quality information to transmit, from a quality information calculation/transmission unit (17B), the quality information (51) to an accumulation server (15). The accumulation server (15) saves, in a quality information database, packet quality information (52) for each reception terminal (18).

6. A communication quality management apparatus for multicasting data from a distribution server to reception terminals via a router connected to a network, the apparatus comprising:
-
a server proxy arranged between the distribution server and the router to add quality information to a multicast packet received from the distribution server and retransmit the multicast packet with the added quality information via the router; a reception terminal proxy arranged between the router and the reception terminal and including a quality information acquisition unit which acquires, from the multicast packet, the quality information added by said server proxy and a quality information calculation/transmission unit, said reception terminal proxy distributing, to the reception terminal, the multicast packet from which the quality information is removed; and an accumulation server which receives and accumulates the quality information from said reception terminal proxy. - View Dependent Claims (7, 8)

9. A communication quality management apparatus for multicasting data from a distribution server to reception terminals via a router connected to a network, the apparatus comprising:
-
a server proxy arranged between the distribution server and the router to add quality information as a quality information header to a multicast packet received from the distribution server and retransmit the multicast packet with the added quality information via the router; reception terminal proxies arranged between the router and corresponding reception terminals, which reception terminal proxies distribute the multicast packet to the reception terminals, the reception terminal proxies including; a quality information acquisition unit, which removes the quality information header from the multicast packet, acquires the quality information from the quality information header, and distributes the multicast packet, from which the quality information header is removed, to the corresponding reception terminal, and a quality information calculation/transmission unit, which processes the acquired quality information and calculates results based on the processed quality information; and an accumulation server which receives and accumulates the quality information and the calculation results from each reception terminal proxy for each of the reception terminals.
