Comparison of IPSec VPN and ssl vpn technologies

This article compares the IPSec VPN and ssl vpn technologies in detail, so that users from all walks of life can better understand the VPN technology and select the appropriate VPN product. Another VPN implementation technology different from the traditional

Test System Architecture designer must watch-Multicast

I. Data Transmission over an IP Network Multicast technology is one of the three methods of data transmission over an IP network. Before introducing the IP multicast technology, we will give a brief introduction to the unicast, multicast, and broadcast modes of data transmission over an IP network: GroupBroadcast Unicast transmission: Implements point-to-

Broadcast and Multicast

Introduction In Chapter 1st, we mentioned three IP addresses: unicast address, broadcast address, and multicast address. This chapter introduces broadcast and multicast in more detail.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. TCP is a connection-orie

Java Peer-to-peer Computing Practice: Discovery based on IP multicast

To accomplish useful work, peers in peer-to-peer applications must be able to discover each other and interact with each other. This article provides an implementation of a discovery based on IP multicast. Before a software entity can participate in a direct peer-to-peer interaction with a Peer-to-peer application feature, the entity must discover the appropriate peers to interact with. All available Peer-to-peer architectures provide a solution for

Concepts related to multicast

Class D addresses are used for multicast, which starts with 1110, and the remaining 28 are used to identify multicast addresses (the remaining 28 are non-structured addresses ), MAC addresses starting with 01005e are used to represent MAC multicast addresses, while the remaining 23 are used to identify multicast. IP

Python enables the sending and receiving of multicast data

In the project, the Ys Private protocol uses multicast technology, which uses Python to send multicast packets when verifying its security features, and to make a record here. Python has complete support for sockets. Some of the APIs though have a different signature than the POSIX equivalents. It is therefore possible to write multicast servers and clients

The MAC address is divided into two parts, the first 24 bits being the organization's unique identifier (OUI, organizationally unique identifier), and the last 24 bits being assigned by the vendor itself.MAC addresses have uni

Linux Network Programming-multicast

OverviewUnicast is used for end-to-end communication between two hosts, and broadcasts are used for data communication on all hosts on the entire LAN for a host. Unicast and broadcast are two extremes, either to communicate with a host, or to communicate with hosts on the entire LAN. In practice, it is often necessary to communicate with a specific set of hosts, rather than all hosts on the entire LAN, which is the purpose of multicasting.IP Multicast

What is unicast, multicast, and broadcast? BR

What is unicast, multicast, and broadcast? The terms unicast, multicast, and broadcast are all terms used to describe the communication methods between network nodes. So what exactly do these terms mean? What is the difference? Let's break it down. --★Unicast★--The communication between network nodes is like a conversation between people. If a person speaks to another person, the term network technology is

IP multicast technology

In recent years, with the rapid development of information technology, a large number of network applications have increased, so that the existing huge data transmission volume has multiplied, and the optimized bandwidth can meet the needs of increasing data transmission volume, IP multicast technology is an important means to optimize bandwidth. It is applicable to data transmission services from multi-point to multi-point or from one point to multip

A required technology for next-generation networks-IP multicast is mature

With the development of broadband, the increasing demand for multimedia services has stimulated the popularization and development of IP multicast technology and become an indispensable key technology for the next generation of networks. Currently, the IP multicast technology is quite mature, which means that operators and enterprises can use this technology to obtain economic benefits. Mature IP

IP multicast host Extension

1. Introduction IP multicast transfers data to some hosts. One or more hosts are represented by one IP address. Multicast transfers data to all hosts in the best way like normal IP Address Transmission. The group members are dynamic. Members can join or leave a group at any time. The group size and position are not limited. A host can be a member of multiple groups. The Group can be permanent or temporary.

TCP/IP protocol Volume one-----------broadcast and multicast

The little Porter is here again, 51 holidays are over.1. Introduction Broadcast and multicast only apply to UDP because TCP is a connection-oriented protocol (IP address determination) Unicast: The Ethernet frame is only destined for a single destination host, and the destination address indicates a single receive interface. In this mode, any two host communication will not affect the other hosts in the network (except for the

Analysis of Dynamic Multi-Point VPN

Encryption, the center needs to decrypt the data transmission branch tunnel and re-encrypt the received data in the branch tunnel. Another case is that the two branches of communication are in the same city and the center is in another city, which introduces unnecessary latency. When the scale of the star IPSec network (hub-and-spoke) continues to expand, the configuration of the Traditional VPN becomes more complex and is not easy to maintain and tr
