Problems solved by technology

However, this method is relatively fixed and less flexible. It only supports one type of L2VPN or L3VPN, and cannot flexibly choose between L2VPN and L3VPN. It only supports global configuration, and all dynamic flows use the same VPN. Scenarios that support multiple VPNs

[0091] See figure 1 , which is a schematic flowchart of a method for transmitting a dynamic stream according to the first embodiment of the present invention, the method includes:

[0092] S101. The routing device configures a virtual private network identification (VPN ID) and a layer-2 virtual private network (L2VPN) or a layer-3 virtual private network (L3VPN) on a cable modem (CM) configuration file or a cable modem termination system (CMTS). The corresponding relationship of the first preset parameter of the virtual private network is established, and the first association mapping between the virtual private network identifier and the forwarding path of the virtual private network is established.

[0093]Optionally, the first preset parameter includes a routing forwarding table (Virtual Routing Forwarding, VRF), a virtual link (Pseudo Wire, PW), a virtual local area network (Virtual Local Area Network, VLAN) or a multi-protocol label switching (Multiprotocol Label Switch...

Abstract

The embodiment of the invention discloses a method for transmitting dynamic streams and a routing device. The method comprises the steps that the routing device configures a corresponding relationshipbetween virtual private network identities and first preset parameters of a layer 2 virtual private network or a layer 3 virtual private network in a cable modem configuration file or a cable modem termination system and establishes first association mapping between the virtual private network identities and virtual private network forwarding paths; a corresponding relationship between the virtual private network identities and second preset parameters of a terminal employing the dynamic streams is configured, and second association mapping between the dynamic streams and the virtual privatenetwork identities is established; third association mapping between the dynamic streams and the virtual private network forwarding paths is established according to the first association mapping andthe second association mapping; and determining a transmission path with the terminal according to the third association mapping and finishing transmitting the dynamic streams. Through adoption of themethod and the routing device, the flexibility of transmitting the dynamic streams can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for transmitting dynamic streams and a routing device. Background technique [0002] Data Over Cable Service Interface Specification (DOCSIS) is a set of high-speed bidirectional data service transmission on Hybrid Fiber-Coaxial (HFC) network developed by CableLabs. interface specification. Among them, the cable modem termination system (Cable Modem Termination System, CMTS) belongs to the head-end (office end) equipment, which can be deployed at the front-end of the cable television network, and can also be deployed at the optical node in the bidirectional HFC network. Cable Modem (CableModem, CM) is a terminal device, between the HFC network and the user end device; CMTS and CM complete the process of interactive transmission of data signals on the analog channel. In today's world of economic globalization, connection channels may be established between various...
