Embodiment Construction

[0011] The MoCA head-end with multiple VLAN modes of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings, so that the advantages and characteristics of the present invention can be more easily understood by those skilled in the art, thereby making a more detailed description of the protection scope of the present invention. to clearly define.

[0012] Such as figure 1 As shown, the CPU and the PHY chip are connected through the MII to realize data forwarding, the MoCA main chip and the CPU are connected by a PCI interface, and the core running in the CPU uses the PCI driver to access and control the MoCA main chip to realize data forwarding. The skbuff structure transmits data packets. skbuff is a structure transmitted by Linux in its protocol stack, which contains the headers of various layers of protocols, such as ethernet, ip, tcp, udp, etc., and also contains Ethernet data packets. information such as the s...

Abstract

The invention discloses a multimedia over coax alliance (MoCA) head end provided with various virtual local area network (VLAN) patterns. The MoCA head end provided with the VLAN patterns comprises a MoCA main chip, a central processing unit (CPU) and a physical layer (PHY) chip, wherein the CPU and the PHY chip are connected through a media independent interface (MII) to achieve transmission of data, the MoCA main chip and the CPU are connected through a programmable communication interface (PCI), an inner core which operates in the CPU accesses and controls the MoCA main chip through adoption of a PCI drive to achieve transmission of the data, and a sk_buff structural body in the PCI drive is applied to transmit a data package. The head end is provided with a VLAN processing function and suitable for a single-port terminal network, a manageable multi-port terminal network, or a network with a single port and a manageable multi-port terminal mixed in a current broadcast television network. The problem that various MoCA terminals exist in the same network in different periods is solved, and multi-business application requirements of broadcast television users are met.

Description

technical field [0001] The invention belongs to the technical field of network communication and radio and television, and relates to a MoCA (MultimediaoverCoax Alliance, Multimedia over Coax Alliance) headend, in particular to a MoCA headend with multiple VLAN modes as an access device. Background technique [0002] As a broadband network access technology, MoCA technology uses existing coaxial cables to achieve high-speed, high-reliability access and network transmission without any adjustments. Compared with xDSL and Ethernet, it has advantages and has been adopted More and more radio and television operators are using it. With the advancement of triple play, more and more radio and television operators will only provide a single Internet service at the beginning, and gradually begin to increase interactive on-demand services such as IPTV and IPCAM. [0003] VLAN (Virtual Local Area Network, Virtual Local Area Network) is a new data exchange technology that logically divi...
