Problems solved by technology

[0013] Although the existing IPv6-based routing protocols support multicast and quality-of-service (QoS)-oriented transmission functions, they cannot effectively provide QoS guarantees. At the same time, the various quality-of-service (QoS) routing algorithms currently proposed are difficult to deploy in actual networks. middle

Embodiment 1

[0081] Construct an IPv6-based QoS controllable video conferencing system. Its hardware platform includes 22 PCs, of which 16 are used as prototype routers and 6 are used as application servers; 22 INTEL network cards, 35 TP_DLINK network cards, 30 network cables, and 1 Huawei S2016 switch. The configuration of each machine:

[0082] 1) 4 prototype routers, the specific models are as follows: CPU is Intel P4 2.0; memory is 256M; hard disk is 40G;

[0083] 2) One prototype router, the specific model is as follows: CPU is 512 Intel P4 2.4; memory is 512M; hard disk is 80G;

[0084]3) 5 prototype routers, the specific models are as follows: CPU is Intel P4 2.6HT, memory is 512M; hard disk is 160G;

[0085] 4) 6 prototype routers, the specific models are as follows: CPU is Intel P4 3.0HT; memory is 1G; hard disk is 160G;

[0086] 5) 6 application servers, the specific models are as follows: CPU is Intel P4 2.6HT; memory is 512M, hard disk is 160G.

[0087] The software platform is con...

Embodiment 2

[0108] Take the video conferencing system of embodiment 1 as an example to illustrate the method of controlling the quality of service of allocating bandwidth, such as Picture 12 As shown,

[0109] Specific steps are as follows:

[0110] Step 1: The application server E generates a multicast listener message (MLDv2) join message (join) according to the service type, and sends it to the router directly connected to it; the service type refers to a file transfer protocol;

[0111] Steps 2 to 4 are consistent with the operation steps of Example 1.

[0112] Step 5 The application server A sets the data_descripition object and the sender-tspec object, generates an RSVP_PATH message, and sends it in the form of multicast data. Among them, setting the data_descripition object means setting the reservable bandwidth, number 201; setting the level field of the sender-tspec object, setting it to 1, and setting the F field to 2;

[0113] Step 6 is consistent with the operation steps in Exampl...

Abstract

A quality control method for multicast service based on IPv6 belongs to the field of computer network communication. The method expands MLDv2 protocol, and adds service type fields; adds service type fields in PIM-SSM protocol message; adds data-description object and resv-description object in RSVP message; expands sender-tspec object and flowspec object in standard RSVP protocol; expands multicast router table, adds service type fields, control scheme fields, distribution layer/bandwidth fields, queue serial number fields and filter serial number fields to realize quality control for multicast service based on IPv6. The invention uses current network resource in a minimum way to ensure the service quality requirement of users; when the network is overloaded or congested, the service quality control method can prevent the important portfolio from being delayed or abandoned and ensure the efficient running of the network.

Description

[0001] Design field [0002] The invention belongs to the field of computer network communication, and particularly relates to an IPv6-based multicast service quality control method. Background technique [0003] With the continuous expansion of network scale and the continuous growth of new network application requirements, the current development of the Internet (Internet) is facing many challenges: lack of address space; digital divide; difficulty in real-time end-to-end applications; difficulty in developing new services; Mobility support is limited; there are many network security vulnerabilities; it is difficult to guarantee the quality of service (QoS); various repair links have led to more and more complex networks, high operating and maintenance costs, and so on. The Next Generation Internet (NGI) with IPv6 as the core came into being. The information highway plan proposed by the US government in 1993 not only promoted the development of the Internet itself, but also promo...
