IPv6 anycast Technology and Its anycast Address Resolution Protocol
Author: Wang Jianli fangwei
Abstract: anycast is a new network application. Anycast communication supports service routing. However, many definitions of anycast communication in IPv6 are vague, and no protocol standards have been reached in controlling routes, therefore, anycast communication between nodes cannot be implemented. In this article, we will first describe the anycast Communication Based on IPv6 and many potentia

General question:
First of all, the "general question" described below is not the original intention of the question, but it is impossible to perform AC based on the original intention of the question, because the test database is very different from the original intention of the question. By the way, it is recommended that you do not want to do this if you are new to poj, because if you do
acronymsAcronyms are words that consist of the first letter of each word in a term or phrase. For example, HTML is an acronym for Hypertext Markup Language. Acronyms should be used in identifiers only if they are widely recognized and understood by the public. Acronyms are different from abbreviations because abbreviations are abbreviations for a word. For example, theID is an abbreviation for identifier . Typically, the library name should not use a

True when the data packet is an IP broadcast data packet. It checks all broadcasts, including the addresses 0 and 1, and then checks the subnet mask.

identifiers.For all public members, types, and namespace names composed of multiple words, use Pascal case.
Note that this rule does not apply to instance fields. Public instance fields should not be used because of the detailed description in the member design guidelines.Use case-insensitive mixing for parameter names.
The following table summarizes the upper and lower case rules of identifiers and provides examples of different types of identifiers.
