Configure jumbo frame for RAC optimization and jumboframe for rac Optimization Configure jumbo frame for RAC Optimization) First, let's talk about the concept of MTU: in network communication, there is a concept of MTU (Max Transmission Unit), that is, the maximum frame size in network Transmission, the default value is 1500 bytes (the Ethernet Variable frame size is 46-1500Byte ).

ForWe will surely encounter this situation: Bank A and Bank B open your account almost simultaneously and see the original 1000 yuan deposit in your account, then both banks want to add a deposit of 500 yuan to your account. Then, Bank A will change 1000 yuan to 1500 Yuan, and Bank B will also change 1000 yuan to 1500 yuan. This is terrible! In the end, your bank account has only

determined by the physical characteristics of the Ethernet. This 1500 byte is called the MTU (maximum transmission unit) of the link layer ). The Internet Protocol allows IP sharding so that data packets can be divided into small fragments to pass through links with the maximum transmission unit smaller than the original size of the data packet. This fragment process occurs at the network layer. It uses the value of the maximum transmission unit that

counted as a group? What's the point of each signal bit? This is the function of the "link layer", which determines how 0 and 1 are grouped above the "solid layer". 3.2 Ethernet Protocol In the early days, each company had its own way of grouping electrical signals. Gradually, a protocol called "Ethernet"(Ethernet) occupies a dominant position. Ethernet requires that a set of electrical signals constitute a packet called "frame". Each frame is divided into two parts: header (head) and data.

sectionsHead contains: (fixed 18 bytes) Sender/Source Address, 6 bytes Recipient/Destination Address, 6 bytes Data type, 6 bytes Data contains: (minimum 46 bytes, maximum 1500 bytes) Details of the packet Head length +data length = Shortest 64 bytes, up to 1518 bytes, over maximum limit on shard send MAC Address: Ethernet Specifies that devices that are connected to the Internet
