routing protocols

different, peer network, Opportunity Network, random networks, self-organizing networks, mobile networks, the communication path of nodes and nodes in such networks is unpredictable, even if the long connection protocol, Routing items that have been cached on the last location node router will no longer have a chance to hit because of the fast movement of the nodes, even if we don't consider mobility, consider some signaling

upgraded.IPv6 is not backward compatible. The hardware and software used for communication routing and security analysis of the entire network must be upgraded to support the IPv6 protocol. Otherwise, these hardware and software do not support the IPv6 network protocol. Remember this when using boundaries to protect devices. To be compatible with IPv6. routers, firewalls, and intrusion detection systems all require software or hardware upgrades. 3. A

Transmission Protocol (2) Presentation Layer: The main function of this layer is to define the data format and encryption, which is generally encrypted in ASCII format. (3) Session Layer: defines how to start, control, and end a session, including the control and management of multiple two-way messages, so that the application can be notified when only part of the continuous messages are completed, the data displayed in the presentation layer is continuous. The main

basis for building a connection-oriented protocol. TCP/IP is based on a 4-tier protocol stack, as shown in:, both TCP and UDP are built on top of the IP. Therefore, IP is the basis for building the entire TCP/IP protocol family. But IP provides a best-effort, unreliable, non-connected service. It receives packets from its upper layer, encapsulates them in an IP packet, selects the correct hardware interface for grouping according to routing, and send

The OSPF dynamic routing protocol is worth learning a lot. Here we mainly introduce the internal zone routers, including the area border routers and backbone routers. One reason for OSPF's scalability is its route update mechanism. The OSPF dynamic routing protocol uses LSA to share routing information among OSPF nodes. The broadcast information will be transmitt

The routing protocol of swift WMN is called WMN. It is a distributed network with high capacity and high speed. Different from the traditional wireless network, it can be regarded as a combination of WLAN and Ad Hoc networks, they have also taken advantage of both, as a new network structure that can solve the bottleneck problem. 1. Currently, the implemented WMN adopts the TBRPF-based routing protocol, the

We use the Internet every day, how is it implemented?The core of the Internet is a series of protocols that collectively "Internet Protocol" Internet Protocol suite.1: Overview1.1 Five-layer modelThe realization of the Internet, divided into several layers, each layer has its own function, each layer on the next layer of supportHow to layered with different models, some divided into seven layers, but divided into 5 layers is relatively easy to underst

1. Network Protocol (PMTOCOL)The so-called network protocol is a set of rules, standards, or conventions established for the exchange of data in a computer network. A protocol always refers to a layer of protocol,accurately, it is a collection of communication rules and conventions that are developed for communication between the same layer entities. The network protocol consists of three elements:① semantics include control information for various frame headers and processing. ② syntax includes

same network topology database and routing algorithm. In the optical network, route selection is provided when a request is made to establish a connection, and the existing services are not affected when the connection is established. The optical network routing protocol flexibly contains various new information. bandwidth statistics in the optical network are also simpler than those in the IP network, mak

"routing IPX add/set staticroute, "routing ipx set global" indicates configuring global IPX route settings. SPX Protocol (Sequences Packet Exchange). The SPX Protocol is based on Xerox SPPSequences Packet Protocol, it is also a network protocol for LAN developed by Novell. In the LAN, the SPX protocol is mainly responsible for error-free processing of the entire transmitted data, that is, error correction.

In the reality of the network, the network connection is linked to the link protocol, but the Protocol is not the same, can not directly connect to use, our common in the reality of the Protocol is the RIP protocol and OSPF protocol. Today's experiment is about using the two protocols together. Experiment shows: This experiment is to do the OSPF routing and RIP routing
