Distribution among peers. it's very cost valid tive as the stream is distributed among peers. you can either distribute stream from a client or FMS (with the future release ).
Native IP MulticastThis one is distributed over the network not using P2P connection, but using network routing capabilities. it mostly works in internal, enterprise, VPN or LAN networks-basically in closed networks, which supports that. you can combine native IP Multicast with application level multicast to deliver comb

ProgramDESIGN: when the cat shouted, all the mice started to escape and the host was awakened. (C # language)Requirements:
1. The behavior of rats and Masters Should Be passive.2. Considering scalability, the call of a cat may cause other association effects.

I. Program Design: when the cat shouted, all the mice started to escape and the host was awakened.
Requirement: first, the interaction between the mouse and the host is passive. Second, considering scalability, the call of a cat may cause other linkage effects.
Answer:
1. Use inerface design:
Using System;Using System. Collections. Generic;Using System. Text;Using System. Collections;
Class Program{Static void Main (string [] args){Cat cat = new Cat ();Mouse mouse1 = new Mouse ("mouse1", cat );M
The cat shouted, and all the mice started to escape, and the host was awakened. (C # language)
1. The behavior of rats and Masters Should Be passive.
2. Considering scalability, the call of a cat may cause other association effects.
1. Use interfaces:Code

reports. A, monthly Statement (monthly Report)-------All transactions list for the month of the selected category. B, Annual cumulative Amount (YTD Sales chart)-Displays the annual cumulative amount of the selected category in months. (3) When a different category is selected, the data for both reports is refreshed, displaying the report for the currently selected category. To achieve the desired functionality, it is easy to see that two report objects rely on objects that hold user

Program design: The cat shouted, all the mice began to flee, the owner was awakened. (C # language)Requirements:1. To have linkage, the behavior of the mouse and the host is passive.2. Considering scalability, cat calls can cause other linkage effects.
Main points: 1. Linkage effect, run the code as long as the cat.cryed () method is executed. 2. Abstract the mouse and the hostRating criteria:
