SMDS few megabyte of data exchange service
SMDS is a principle based on the kinds of switched virtual circuit packet switching of the fast-small (cell-switching) data services technology. Small package means the length of the fixed 53-byte packets. At this stage the number of megabytes of data exchange service rate is not 44.736Mbps (T3) is a 1.544Mbps (T1), the next few years will increase to 155Mbps (OC-3).
The number of megabytes of data exchange service is ideal for business and enterprise communication between each other, especially the different short-term co-operation between enterprises wishing to develop new products or new systems to better show the number of megabytes of data exchange service of the urgent need to .
The number of megabytes of data access rate of exchange service is currently divided into six, namely, 1.17Mbps, 4Mbps, 10Mbps, 16Mbps, 25Mbps and 34Mbps. 1.17Mbps via T1 implementation; 10Mbps, 16Mbps, 25Mbps and 34Mbps, through the implementation of T3. As for the 4Mbps to 10Mbps on the need to upgrade the software with.
The number of megabytes of data exchange service then it is free-style service, easy to install. Not need to specify the virtual circuit CIR (Committed Information Rates, CIRs), the largest small packet rate (Peak Cell Rate, PCR) as well as the propagation delay tolerance.
