Patent number: 8477626Abstract: Provided are a packet processing apparatus for realizing a wire-speed, and a method thereof. The packet processing apparatus realizes a wire-speed by making an inputted packet be processed in another packet processing apparatus instead of processing the inputted packet for itself. The packet processing apparatus for realizing a wire-speed by having an inputted packet processed in a packet processor of another packet processing apparatus by making an inputted packet detour a packet processor into a detour path, includes: a packet classifier for classifying and storing the inputted packet in a multi-queue based on a priority; a queue manager for including the multi-queue, determining a detour packet among packets stored in the multi-queue and marking the packet as a detour packet; and a packet scheduler for transmitting the packet designated as the detour packet to the detour path. The apparatus is used for a packet communication system.Type: GrantFiled: December 29, 2008Date of Patent: July 2, 2013Assignee: Electronics and Telecommunications Research InstituteInventors: Jin-Ho Hahm, Hae-Won Jung

Patent number: 7652989Abstract: In the adaptive connection admission control method of the present invention, a corresponding ingress edge node performs connection admission control for a new connection within the amount of bandwidth initially allocated to each of paths between the ingress and egress edge nodes. The amount of remaining bandwidth allocated to a specific path Pr is compared with an amount of bandwidth required for a call requesting new connection setup input to the corresponding ingress edge node. The amount of additional bandwidth to be requested from the bandwidth broker is predicted when the amount of the remaining bandwidth does not satisfy the amount of bandwidth required for the connection setup requesting call. The ingress edge node requests additional bandwidth from the bandwidth broker on the basis of the predicted amount of the additional bandwidth, changing bandwidth information of the corresponding path Pr, and performing connection admission control.Type: GrantFiled: April 16, 2004Date of Patent: January 26, 2010Assignee: Electronics & Telecommunications Research InstituteInventors: Mi Jung Yang, Woo Seop Rhee, Jin Ho Hahm, Young Sun Kim, Jun Hwa Lee, Sang Ha Kim

Patent number: 7477599Abstract: The system of the present invention guarantees quality of service with respect to packets transmitted/received between an external network capable of providing differentiated services and a home network. The system includes a packet classifier, a marker, a priority class queue, a scheduler and a token bucket. The packet classifier classifies the packets according to addresses and traffic types. The marker allocates information on priorities to packets transmitted from the home network to the external network. The priority class queue has a plurality of queues classified according to the priorities. The scheduler services packets stored in the priority class queue according to the priorities. The token bucket drops packets, bandwidths of which are above a preset maximum bandwidth, when the packets are generated.Type: GrantFiled: November 2, 2004Date of Patent: January 13, 2009Assignee: Electronics and Telecommunications Research InstituteInventors: Wang Bong Lee, Jin Ho Hahm, Young Sun Kim
