What is the difference between MTU and PMTU?

Image
MTU (Maximum Transmission Unit) The maximum transmission unit is used to notify the other party of the maximum size of the data service unit that can be accepted, and to indicate the size of the payload that the sender can accept. Both Ethernet and 802.3 have a limit on the length of the data frame, and their maximum values  are 1500 bytes and 1492 bytes, respectively. This characteristic of the link layer is called MTU, which is the maximum transmission unit. Most types of networks have an upper limit on the length of several frames. If there is a datagram to be transmitted in the IP layer, and the length of the data frame is greater than the MTU of the link layer, then the IP layer needs to be fragmented (fragmentation), that is, the datagram is divided into dry slices, so that each slice is smaller than MTU. Different data links have different maximum transmission units (MTU). Since the IP protocol is the upper layer of the data link, it must be able to be used wi...

CCIE Routing & Switching: TS2 + + Diag3 LAB1

Speaking about the overall feeling of the test, the examination room except the desktop mouse control is not very sensitive and other parts are very smooth. I have (shift + Insert) that DELL keyboard and mouse feel great. txt shortcut that  you can create multiple texts on your desktop. There has a sheet of personal information white paper that you can use as scratch paper. Also , there has a water fountain, a bread and a pen,etc. To thanks, I want to thank my family for their support. I also want to thank the teachers of  PASSHOT  and everyone who helped me along the way. Finally, I wish all the friends on the CCIE road can get their CCIE number as soon as possible! (1) TS2++ Q3 SW110-SW210 exchange visits did not occur. At the beginning, I was nervous but I thought it would not be a Bug. In fact, to the back of the same and finally also according to the solution to complete. Set 9 phenomena. Tip: I suggest you don't go directly to the wrong spot. First, use the met...

Detailed interpretation of IPSec protocol

Image
IPSec (Internet Protocol Security) is a set of open network security protocols formulated by IETF (Internet Engineering Task Force). It is not a single protocol, but a collection of protocols and services that provide security for IP networks. It provides high-quality, interoperable, and cryptographic-based security guarantees for data transmitted on the Internet. IPSec mainly includes security protocols AH (AuthenticationHeader) and ESP (Encapsulating Security Payload), key management exchange protocol IKE (Internet KeyExchange), and some algorithms for network authentication and encryption. IPSec mainly uses encryption and verification methods. The authentication mechanism enables the data receiver of IP communication to confirm the true identity of the data sender and whether the data has been tampered with during transmission. The encryption mechanism guarantees the confidentiality of the data by encrypting the data to prevent the data from being eavesdropped during transmission. T...
