Problems solved by technology

However, in the traffic engineering, there is no function corresponding to the change of the frequency band utilization rate after the route is set, so the problem that the processing is concentrated on a specific line when the traffic volume is large has not been solved.

Embodiment Construction

[0073] Next, embodiments of the present invention will be described in detail.

[0074] figure 1 is a block diagram showing the basic configuration of an apparatus to which the present invention is applied.

[0075] The premise of the information relay device of the present invention is that it can be used in a network in which large-capacity data traffic frequently occurs and in an access network in which broadbandization is increasing in recent years.

[0076] The information relay device includes data receiving units 2 2-1 to 2-n having a plurality of input ports (logical ports) connected to a plurality of lines 4-1 to 4-n to perform line control for connecting devices. , The data transmission unit 3 having a plurality of output ports 3-1 to 3-n connected to a plurality of lines 5-1 to 5-n has an association with the input and output ports in order to switch the input and output routes inside the device The software switch section 1. A method of communicating with progra...

Abstract

A content relay node comprising a data processing unit for storing or transmitting a data packet on the basis of the data attribute, a storage connected to the data processing unit, transmitting units each for processing the header of a data packet in accordance with a control signal from the data processing unit and transferring the data packet to a neighboring relay node, and a routing control unit for selecting the transmitting unit or the data processing unit as a destination of a data packet on the basis of routing information including a storage address, wherein the storage unit stores a copy of a data packet at least until transfer of the data packet to the next node is completed.

Description

technical field [0001] The invention relates to a network route control method and a network relay device. Specifically, the present invention relates to routing of data information packets using application layer data identification information contained in the data information packets in order to efficiently transmit multimedia data such as images and sounds and large-capacity data such as enterprise internal technical data. The data transmission method and its relay device, especially relate to the data transmission method using the address of the storage part in the network with the storage device as the constituent element, the data storage type transmission method and its relay device. Background technique [0002] In the conventional network system, the routing technology of the network layer protocol based on the ISO reference model is used. The main protocols include: Routing Information Protocol (RIP) that determines the optimal route based on the number of router...
