Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The method provided by the present invention mainly includes: after the switch receives the name registration message, obtains the host name and IP address contained in the name registration message, and judges whether it has stored the table entry containing the host name, and if not, stores the host name and IP address containing the name registration message. The table entry of the host name and IP address, and forward the name registration message; if so, further judge whether the IP address contained in the name registration message is the same as the IP address in the table entry containing the host name stored by itself , if yes, update the aging time of the entry stored by itself, and discard the name registration message.

Abstract

The invention provides a method and a switchboard for processing messages, which can judge whether the list items containing the host name carried in the name registration message are stored or not after receiving a name registration message,, if not, the list items containing the host name and the IP address carried in the name registration message are stored; if yes, the IP address carried by the name registration message is further judged whether to be the same as the IP address in the self-stored list items containing the host name; if the IP addresses are the same, then the maturing timeof the self-stored list items is renewed and the name registration message is brushed off; corresponding list items are stored in the switchboard, thus avoiding the broadcast of the name registration message in network, reducing the quantity of messages broadcasting in the network and reducing the burden of the network.

Description

technical field [0001] The invention relates to network communication technology, in particular to a message processing method and switch. Background technique [0002] Network Basic Input / Output System (NetBIOS, Network Basic Input / Output System) is a transmission protocol interface used by local area networks. Functionally speaking, NetBIOS can be regarded as a set of intra-process communication services, which can be divided into three categories : name service, session service and datagram service, the present invention mainly relates to name service wherein. [0003] Each network device in the LAN mainly broadcasts its own NetBIOS information, for example, publishes its own host name and IP address, and broadcasts to query the NetBIOS information of other hosts to resolve the names of other hosts. by figure 1 The shown LAN network structure is an example. After host A logs in, it will broadcast a name registration message containing its own host name and IP address in...
