Information processor and data transmission system and method

Abstract

An information processor includes a network adapter connected to a network for transmitting data at the data link layer level, and a setup processing section for recognizing the network adapter connected to the network within a memory, sending out a broadcast packet that requests a response at the data link layer level to the network via the recognized network adapter, verifying a response packet transmitted via the network, acquiring a hardware address and an IP address from the response packet, and thereby performing setup for data transmission at the data link layer level and the transport layer level, and automatically performing a data migration or exchange process between information processors.

Description

technical field [0001] The present invention relates to an information processor for transmitting data through a network, in particular to an information processor for transmitting data used to construct a network environment for an information processor ready to join an existing network, a data transmission system, a data transmission method and a user An information processor executable program for causing the information processor to execute the data transmission method. Background technique [0002] Typically, there are multiple information processors connected to a network environment, and they share applications, databases, printers, etc. This network environment makes office work more efficient and thus has recently become a common form of interconnecting information processors. Therefore, there is an increasing need for information processor maintenance and management work and information processor replacement connected to such a network environment. When connectin...

Problems solved by technology

However, ARP is only available when the IP address is known, so it is not suitable for establishing a handshake connection between two information processors with higher information reliability and more information when the IP address of the opposite end is unknown

In addition, in the case of constructing a network environment on the user side, there is a possibility that the priority of the network adapter set by each user for each information processor that has been used and connected to the network environment is different.

In general, from the perspective of security management, it is not applicable that the service provider does not have to verify or change the relevant information of the personal information processor managed by the user to deal with the above problems
