Patent number: 7647393Abstract: The present invention provides a server load balancing apparatus using MPLS session labels. The server load balancing apparatus includes a packet analyzing unit, a load balancing processing unit, a session label switching unit, a session managing unit, and a session label managing unit. The packet analyzing unit inspects whether a session label has been attached to a received packet, analyzes header information of the received packet to learn session information, and attaches a session label to a header of the received packet. The load balancing processing unit assigns a server to a session of the received packet without the session label attached. The session label switching unit hardware-switches the received packet with the session label attached using only the session label information. The session managing unit manages and maintains relevant information and states of sessions. The session label managing unit manages the session label.Type: GrantFiled: April 15, 2004Date of Patent: January 12, 2010Assignee: Electronics and Telecommunications Research InstituteInventors: Sun Hee Yang, Hyeon Sik Yoon, Pyung Koo Park, Ho Sun Yoon

Publication number: 20040109687Abstract: The present invention provides a fast rerouting method through Generalized Multi-Protocol Label Switching (GMPLS). The method performs fast rerouting through when a failure occurs on a link and node in an optical network having a plurality of nodes. In the fast rerouting method, current node of the optical network receives the path message for label request from a higher node thereof and establish the main LSP. Further, the current node calculates a detour path therefrom to a next but one node thereof so as to provide against a failure of the next node. Further, if it is checked that the Loss Of Light (LOL) occurs in the current node, the current node establishes the detour path to allow data to flow through the calculated detour path.Type: ApplicationFiled: November 6, 2003Publication date: June 10, 2004Inventors: Hyeon Park, Sun Hee Yang, Sang Ha Kim, Wan Seop Lee
