Problems solved by technology

The so-called static configuration means that regardless of whether the client device has an uplink transmission requirement, the central office device always allocates a fixed uplink bandwidth for each client device, which obviously cannot make full use of network bandwidth resources

Embodiment Construction

[0036] see figure 1 , which is a structural diagram of an embodiment of the MAC chip of the user end equipment in the EOC network of the present invention, which includes SRAM, memory management module, MAC interface module, packet analysis module, clock synchronization module, registration module, scheduling module, management report A text processing module, a multicast filtering module, an Ethernet interface module, a priority module, a reporting message generating module, a statistical module, and a reset monitoring module.

[0037] There is only one SRAM on the MAC chip, and for the convenience of each module, the memory management module allocates the SRAM into multiple logical buffer areas. The logical cache includes an uplink cache, a downlink cache, and a statistical information cache. The uplink buffer area further includes a high-priority uplink buffer area, a high-priority uplink data packet length buffer area, a low-priority uplink buffer area, and a low-priority...

Abstract

The invention discloses a MAC chip of a user end device in an EOC network, in which the CPU module is omitted, and the functions that need to be completed by the CPU are implemented on the MAC chip of the central end device, and the user end device only plays an execution role, thus reducing the user's The complexity and cost of end equipment. The MAC chip of the present invention realizes the support of the TDMA bandwidth sharing mode by the cooperative work of the reporting message generation module and the scheduling module, and supports the central office equipment to dynamically allocate bandwidth according to the actual needs of each user equipment, compared to CSMA mechanism or static TDMA mechanism has higher bandwidth utilization. The MAC chip of the present invention realizes the automatic reset function under abnormal conditions by the reset monitoring module, so as to improve the robustness of the whole system. The MAC chip of the present invention adopts a shared memory structure to further reduce the chip area.

Description

technical field [0001] The invention relates to a MAC chip of user terminal equipment in an EOC network. Background technique [0002] EOC (ethernet over coax, Ethernet over coaxial cable) network is a point-to-multipoint network, and one central office device is connected to multiple user end devices through a coaxial cable. The EOC network is an access network, and the access network requires central office equipment to centrally manage and configure user equipment. [0003] Most of the current active EOC networks are transformed based on home networking technology, and the essence of home networking is a peer-to-peer network. As far as the MAC layer is concerned, the central office equipment and the user end equipment in the current EOC network have the same MAC chip, and the MAC chip includes a CPU module, so it has strong management and configuration capabilities. The MAC chip of the central office device can help it manage and configure multiple client devices, and t...
