To do useful work, P2P applications must be able to discover and interact with each other. This article provides an implementation of IP multicast-based discovery. Before a software entity can participate in direct peer-to-peer interaction with P2P applications, the entity must discover the appropriate Peer-to-Peer Points to interact. All feasible P2P architectures provide a solution for Problem Discovery. In this article, I will describe the implemen

PIM-DM Basics PIM-DM uses five RIMv2 messages Hello Join/Prune (Add/CUT) Graft grafting) Graft-ACK (OK) Assert (Declaration) The PIMv2 router uses the Hello message to discover the neighbor, when the PIMv2 router PIM-SM or PIM-DM) is active, will periodically send the Hello Message on each interface configured with PIM; PIMv1 vro has similar functions, but uses Query messages. A Hello (or Query) message contains a storage time holdtime, which specifies the maximum time for a neighbor to

Basic multicast knowledge: Common IP communication is performed between a sender and a receiver. We call it point-to-point communication. However, for some applications, this point-to-point communication mode cannot effectively meet the needs of practical applications. For example, a digital teleconference system is composed of multiple venues. When participants in one of the venues speak, other venues are required to instantly obtain the content of t

How to configure cross-route access in NLB multicast Mode Some time ago, because a large number of shared files were required to be accessed, two servers were configured to improve the concurrent access speed, and NBL for windows was used for configuration. There were many configuration methods on the Internet. After configuration, multicast can be accessed locally, but it cannot be accessed from other netw

PIM-DM intensive mode)The PIM intensive mode is the preferred configuration in the multicast routing protocol. This Protocol is strongly supported by Cisco and provides easy configuration and troubleshooting methods. Similar to DVMRP, the PIM intensive mode does not have the characteristics of flooding or deleting. Therefore, it can still be used as an option for configuring short-term protocols for wide-area multi-point transfer. Meanwhile, the PIM S

+ = Operator-= OperatorI learned about multicast delegation. Now let's talk about the + = Operator and the-= Operator.In our previous studies, we know that the + = Operator is used for auto-increment operations, but in the delegate, the + = operator has a new meaning.First look at an instance:First define a delegate typePublic delegate void del (int a, int B );Then define a delegate variable:Del delegate;Now, let's assume that we have the following me

1. Introduction Unicast transfers data to a specific host. If an IP packet is sent to a host, the link layer header is a very specific destination address. For Ethernet, It is the MAC address of the NIC. Broadcast and multicast are only used in UDP. They are very important for applications that need to transmit packets to multiple receivers at the same time. Broadcast is to send packets to all hosts on a network. The network may be a network, a

Broadcast and multicast are only applicable to UDP. Generally, each Ethernet frame is sent only to a single destination host. The destination address specifies a single receiving interface, which is called unicast ). A host sends frames to other hosts on the Internet. This is broadcast. Multicast (multicast) is between unicast and broadcast: Ethernet frames are s

Definition : Delegate It is a type of method reference stored in an object, and also a type of safe function pointer. One way to understand delegation can regard the role of delegation as specifying a name for the method signature. The delegate definition is similar to the method definition, but there is no method body. The keyword delegate must be added before the defined delegate name. Because the definition delegate basically defines a new class, you can define the delegate anywhere in

, which are called multicast delegates. IfYou can call multiple methods in sequence by calling multicast delegates. Therefore, the delegate signature must return void (otherwise, where should the return value be sent ?) (When a delegate only contains one method, its return type declaration can refer to the encapsulated method, not necessarily void ). In fact, if the compiler finds that a delegate returns vo
