Embodiment Construction

[0026] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention adopts the method of detecting the destination network protocol (IP) address of the IPv6 multicast message to determine the type of the IPv6 multicast message: protocol message or data message, so that the multicast traffic used for protocol operation and the common Differentiate the multicast data traffic: that is, the multicast traffic composed of protocol packets is multicast traffic for the protocol, and the multicast traffic composed of data packets is ordinary multicast data traffic, so as to implement different forwarding control strategies. The method of the invention is applicable to access equipment.

[0028] The address-based IPv6 multicast flow control method of the present invention is as follows: figure 1 shown, including the following steps:

[0029] Step 101, determine t...

Abstract

The invention discloses an address-based internet protocol version 6 (IPv6) multicast flow control method, which comprises: determining the type of an IPv6 multicast message according to the address of a target network protocol (IP) of a received IPv6 multicast message; and applying corresponding flow forwarding control policies for different types of IPv6 multicast messages. The invention also discloses an address-based IPv6 multicast flow control device. Based on the method and the device, the problem that a mechanism, which relays on multicast message for protocol operation, of the IPv6 cannot work normally is solved.

Description

technical field [0001] The invention relates to multicast flow control technology, in particular to an address-based IPv6 multicast flow control method and device. Background technique [0002] With the rapid development of the Internet and the rapid expansion of its scale, the existing Internet Protocol version 4 (IPv4, Internet Protocol version 4) faces many problems in terms of scalability, such as insufficient address space and so on. Therefore, Internet Engineering Task Force (IETF, Internet Engineering Task Force) proposed Internet Protocol version 6 (IPv6, Internet Protocol version 6) to solve the above-mentioned problems faced by IPv4 in terms of scalability. Since the IPv4 address space is gradually being exhausted, some short-term solutions to delay address consumption are being implemented, and some long-term solutions such as IPv6 technology are also being gradually implemented. [0003] With the gradual deployment and commercial use of IPv6 networks, in some fi...
