packet switched network definition

1 Introduction Automatically Switched Optical Network (ASON) is a new type of network that can automatically connect to the network. It consists of three planes: control plane, transfer plane, and management plane. The control plane technology is its core. It can implement dynamic exchange using the control plane. GMPL

First, the introduction Automatic Switched Optical Network (ASON) is a new generation of optical transmission network technology which is constantly adapting to the rapid development of the business. Ason Network as a distributed intelligent optical transport network, its b

on the network. Therefore, the network analysis tools in the system are not a threat to the security of the local machine, but a threat to the security of other computers on the network. Tcpdump is defined as simple as possible, namely: dump the traffice on anetwork. a packet analysis tool that intercepts packets on t

Chengdu Neusoft Information Technology Vocational College (Level 04) Apply layer network packet capture using Hook Technology Class: Class 2 of Visual ProgrammingINSTRUCTOR: Li DanStudent ID: 04311110210 Name: Liu Haiping Abstract Packet capture (interception) technology is mainly used in information security-related fields, especially firewall technology. With t

length of the packet end, to determine whether the package tail flag is consistent with our definition, if consistent, this package is a legitimate package. If there is an inconsistency, continue to look for the start flag for the next package and discard the data in front of the next2. The logic layer to determine the validity of the package.When we take out a legitimate package, we also have to judge the

The process of sk_buff encapsulation and Network Packet encapsulation is described in detail.It can be said that the sk_buff struct is the core of the Linux network protocol stack, and almost all operations are performed around the sk_buff struct, its importance is similar to that of BSD's mbuf (I have read "TCP/IP details Volume 2"). What is sk_buff?Sk_buff is t

for the TCP-based development of the communication program, there is a very important problem to solve, that is, packet and unpacking. I. Why TCP-based communication programs require packets and unpacking. TCP is a "flow" protocol, the so-called flow, is a string of data without bounds. You can think of the river water, is connected into a piece, in the meantime there is no dividing line. However, the general communication program development needs to

Network Packet monitoring using raw socket programming in C # Author: Unknown When talking about socket programming, you may think of QQ and IE. That's right.

C # Raw Socket for network packet monitoring, Compared with Winsock1, Winsock2 supports the Raw Socket type most obviously. Using Raw Socket, you can set the NIC to the hybrid mode. In this mode, we can receive the IP packet on the network, of course, for the purpose of not the local IP

Protocol tables in the system. However, to successfully mount the dispatch function, you also need to mount the dispatch function in the ndis_open_block structure corresponding to the Protocol, because NDIS does not directly call the dispatch function address registered by the protocol driver in ndis_protocol_characteristics, rather it calls the dispatch function in ndis_open_block. It is worth noting that in DDK of Windows9x/ME/NT, the definition of
