A Storage Redundancy System of High-speed Ethernet Switch Chip

Abstract

The invention discloses a storage redundancy system of a high-speed Ethernet switching chip, which comprises a plurality of transceiver modules, GMAC modules and data cache modules electrically connected in sequence; a plurality of GMAC modules all interact with a control unit; The determination module, the management unit and the frame analysis module interact with each other; the frame analysis module interacts with the forwarding port determination module through the address management module and the VLAN management module; In this case, it solves the risk of the entire chip being paralyzed by the blockage of the port, reduces the cost of the chip, and ensures the effective forwarding of exchanged data. The storage redundant design circuit structure of the present invention effectively solves the risk of the entire chip being paralyzed by the blockage of the port, and ensures the effective forwarding of exchanged data.

Description

【Technical field】 [0001] The invention belongs to the field of computer communication and network, and relates to a storage redundant system of a high-speed Ethernet switching chip, and is especially suitable for the fields of Ethernet switches, network servers, computer data storage systems and the like. For example, data service centers, large switches, etc. 【Background technique】 [0002] At present, in mainstream Ethernet switching chips, the method adopted is that all switching ports share a storage space. With the improvement of the network transmission rate and the amount of exchanged data, higher requirements are put forward for the management of the storage space of the high-speed Ethernet switch chip. However, when the link of a certain port is blocked, the data frames forwarded to the port will continue to occupy The storage space cannot be forwarded, which leads to full storage resources and eventually causes the switch chip to be paralyzed; if the capacity of t...

Problems solved by technology

[0005] In order to effectively solve the problem that the entire storage space will be occupied when a port of an Ethernet switch chip is blocked, the present invention proposes a storage redundancy system for a high-speed Ethernet switch chip. Dedicated memory, when the link of a certain port is blocked, the data of the port will be stacked in its own dedicated storage space first, which will not affect the shared storage space, avoiding the risk of paralysis of the entire switching chip due to the blocking of a certain port. Thus ensuring the normal forwarding of data
