摘要： A method and system of data communication, switching network board are disclosed. The data communication system includes multiple line card chassis, each including multiple line cards, at least one switching chip and at least one relay chip. The line card is respectively connected to the switching chip and the relay chip of the same line card chassis. The switching chip of one line card chassis is connected to the relay chip of at least one of other line card chassis. The relay chip of the one line card chassis is connected to the switching chip of the at least one of other line card chassis. The switching network board includes a switching chip and a relay chip. By implementing the above embodiments, the networking complexity is reduced, the networking cost is saved and the system reliability is enhanced in the case that a few line card chassis are cascaded.
