Multiprotocol Label Switching Architecture & LDP

IntroductionConventional network forwardingEach router analyzes the coming packet’s header and independently chooses a next hop. Routing algorithm and adequate speed are prerequisite.MPLS forwardingAll forwarding is driven by the labels, no header analysis needed. Once a packet enters a network, it’s assigned a label. Each router forwards packets according their labels.To read further click on the following link below:http://www.mediafire.com/vi...

To the database user, the view appears just like a real table, with a set of named columns and rows of data. But unlike a real table, a view does not exist in the database as a stored set of data values. Instead, the rows and columns of data visible through the view are the query results produced by the query that defines the view. SQL creates the...
