<p><P>PROBLEM TO BE SOLVED: To acquire an End-to-End route even in an IP/MPLS mixed environment. <P>SOLUTION: In a route acquisition method, a transmission source terminal searches for an ordinary IP route (S1), creates an LSP route search notification message (S2) and transmitting it to an LSR; the LSR determines whether or not to pass on an LSP being set by the LSR based on a destination address of the LSP route search notification message, searches a route of the LSP in the LSR when it is determined to pass on the LSP, transmits LSP route information; and, the transmission source terminal derives an entire communication route from both IP route information and LSP route information transmitted from the LSR. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
