SUMMARYThis paper proposes a new system architecture which achieves stable HDTV distribution service using ISP multicast networks. With the recent spread of broadband access networks including FFTH, the distribution of broadcasting contents using IP multicast is becoming indispensable in the ISP service menu. The important issues in the development of such a content distribution service are to provide high service availability and to construct a highly flexible distribution system that can handle various distribution formats. The authors have proposed a nonstop IP multicast technique without modification of router implementation intended for the ISP network, and also a packet transmission control procedure which works independently of the distribution format. A prototype was implemented and a video distribution experiment is performed on an IP multicast network corresponding to digital HDTV broadcasting by satellite. It is shown that nonstop service can be provided using the prototype system, compensating the loss of approximately 27,500 packets, accompanied by detection and recovering of network failure at the router.

“…The IGMP/PIM processing time in each router for backup setting, and the delay from IGMP transmission to (B, Gb1/Gb2) packet arrival (multicast join latency: tree construction time) were measured 10 times each by using a packet capture system [28] with 1-µs timestamp resolution. Table 2 shows the test results.…”

“…The number of main groups varies from 1 to 3, i.e. join latency values of a maximum of 3 pairs of backup groups (6 groups in total) are measured using our proprietary passive GbE monitor providing accuracy to the microsecond [23]. In all cases, UDP clients can receive (M, Gm) the packets proxy distributed from the multicast gateway.…”

This paper presents an architectural concept for IP-based TV broadcasting infrastructure on ISP's multicast network. As broadcasting grows into an indispensable service menu for ISP, its service availability and independency of content format are crucial issues for smooth business deployment. Hence we newly propose some practical solutions to realize a non-stop IP broadcasting service with simple and content format free server implementation. We also implemented a prototype as an HDTV broadcasting system. The verification results show that our system can compensate about 27,500 packet losses and archive non-stop HDTV broadcasting, even in the event of network layer trouble, without any changes in router implementation.

“…HostID: 15 bytes UMAC value: 4 bytes This means that each outgoing IP packet length will be increased by 19 bytes, which approximately 0.0125 of the maximum Ethernet packet (The Ethernet maximum packet length is 1514 bytes). Since, no packet must exceed the Maximum Transfer Unit (MTU) of the network [21,22,23], in this case (Ethernet), therefore, the MTU must be decreased by the total length of the extended information which is 19 bytes.…”

Network security has become one of the most important interesting areas for researches. Protecting the network can be done by many mechanisms. Among the most effective one is the network firewall. While the firewall protecting the network from the external intruding, it does upward nothing about the internal intruding. Internal intruding or Inside attacks can lead to a big loosing. One of these attacks is attaching an unauthorized host to the network to get benefits of using the network resources provided by the server (like Internet service) or to leak information into the outside.To solve this problem, this paper suggested that two new programs have to be built under windows operating system in a client server model, one at the client and another at the server. The first supplies an authenticated unique host-ID to each packet destined to leave the network, while the latter verifies these information, allowing the authenticated packet to pass into its destined while dropping and documenting the unauthorized one.This work is considered as a logical extension of the conventional network firewall and can be installed with any of these firewalls. While the conventional firewall is protecting against outside attacks, this work is protecting against one of these inside attacks.
