Third switchboard choice

The modern local area 350-030 network infrastructure needs to carry on the 350-030 data transmission through the net boundary the question to provide newsolution, this needs to provide one kind simultaneously to have thesecond switchboard and the local area network router function, andmeantime extends is smaller than the 350-030 traditional local area networkrouter brand-new equipment. Usually we call it the third switchboard.
The network all based on the ethernet, FDDI and ATM also is the localarea network backbone technology by no means which most often uses.The ATM net once is regarded as was the 350-030 multimedia time only networktechnology. But many other technical such as 1G ethernets, also will have into tomorrow the local area networkbackbone technology potential. Had quite part of 1G ethernets switchboards already to support QoS and 350-030 CoS, and hasprovided the very high band width, had the transmission sound, theimage, the multimedia data and so on the ability. Although its QoSstability also is inferior to 350-030 ATM, but its low price and the lowcomplexity surpass the ATM technology, also easy with the networkproduct which has has connected. May infer from above these facts, anymust use in the backbone 350-030 net network equipment to have to supportbetween these technical the interconnection, and provides betweenthese technologies carries on the promotion the ability.
In the past, in the network 350-030 data only had probably 20% in the ordinarycircumstances is carries on the correspondence through the backbonerouter and the central server or the enterprise network other parts,but is already enhanced in today this proportion 50%. We all knew, inorder to deal with the data current capacity which unceasingly grows,the sharing medium network is substituted in abundance by the 350-030 exchangenetwork. This kind of change to originally used in the networkpartition traditional router to have the direct impact. In view of thefact that had so the great current capacity to surmount IP or the IPXsub- net, the router already has 350-030 become the network transmissionbottleneck in fact. The reason is because the traditional router paysgreat attention to the many kinds of medium type and the many kinds oftransmission speed support, but the present data cushion and the 350-030 transformation ability and are lower than the line fast handlingcapacity time extends importantly. Although the router performancerecently also obtained the certain enhancement - probably to achieve1Mpps - but to use this kind of router the expense also to be muchhigher.
