the final destination, it will be delivered to the appropriate transport layer protocol. 1. Option Processing Ip_dooptions: processing option. If ip_dooptions returns 0, ipintr continues to process the group. Otherwise, ip_dooptions forwards or discards the group Ipintr can process the next group in the input queue. After processing the option, ipintr compares ip_dst in the IP header with the IP addresses

Java Network Programming (2) InetAddress class and udp protocol, inetaddressudpInetAddress class JDK provides the java.net package for developing network applications. The classes and interfaces under this package are almost all network programming services. InetAddress: the object used to describe the IP address The InetAddress class does not provide a constructor, Instead, a static method is provided to o

helps the devices verify that the network is actually transferring all the packets and that the quality is acceptable. There are several ways to calculate quality; most of these methods compare the time packets arrived to the time they shocould have arrived, and they also detect and count the number of packets that were lost.VoIP elementsoffer-answer The default media negotiation protocol is the Session Description

Basic tutorial for Android -- 7.6.3 Socket communication based on TCP protocol (2)This section introduces: In the previous section, we introduced some basic concepts and usage of Socket, and then wrote a simple chat room for piggyDemo, I believe you have a preliminary understanding of the Socket. In this section, we will learn how to use the Socket to achieve resumable upload of large files!The following

1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test"; 2 function Funcarg () {3 alert (FUNCARG.A

IGMP communicates group membership information between hosts and routers on the local network, and routers periodically multicast IGMP queries to all host groups. Host multicast IGMP reporting messagesIn response to the query.From an architectural standpoint, IGMP is the Transport layer protocol located above IP. It has a protocol number (2), and its message is h

JavaSE-UDP protocol network programming (2), javaseudp In UDP network programming, the sender has no connection with the receiver, and there is no obvious difference between the server and the client. Class DatagramSocket: This class indicates the socket used to send and receive the datagram packet. Main constructor methods: DatagramSocket (): creates an instance, binds the default IP address of the loca

means the server supports TLS, TCP, sctp and UDP in this order.ServiceValue determines the transport type. A client that does not support TLS will choose the second option, "sip + d2t" which means "sip over TCP. "To use TCP, the client now needs to resolve _ sip. _ tcp.arstechnica.com. We have the transport type, but now the port is unknown. it is true that the default port is 5060, but this port will only be used if we cannot resolve a different port. to resolve the port, the client performs a

I2S Audio bus Learning (2) I2S Bus Protocol I. I2S bus Overview The collection, processing and transmission of audio data is an important part of multimedia technology. Many digital audio systems have entered the consumer market, such as digital audio tapes and digital audio processors. For devices and manufacturers, the standardized information transmission structure can improve the adaptability of the sys

is as follows: 1. Allocate and initialize mbuf. Assign the mbuf of the Data header of a group and assign values to the two length fields. 2. initialize the pointer. Assign values to the pointers EA and eh, and assign the value of the ether_arp structure to 0. 3. Fill in the Ethernet frame header. Set the destination ethernet address to an Ethernet broadcast address, and set the Ethernet frame type to ether

, so the rtrequest function is called and the number of references is Rtm_add, the flag is rtf_up and rtf_cloning. Each IFADDR structure has a pointer to a function (Ifa_rtrequest member). This function is invoked on its own initiative when creating or deleting a route table node, and for all Ethernet devices, In_ifinit points the pointer to the Arp_rtrequest function. Therefore, when the call route function creates or deletes a route table node for ARP , Arp_rtrequest is always called, and whe

longer simple 0 and 1, but are divided into 5 levels ( -2,-1,0,1,2). This is divided into 5 levels of level signal called the code element, 1 code elements can carry a number of bits of information depending on the characteristics of the code element and encoding method. For example PAM5, each PAM5 code element carries a maximum of 2.32 bit (22.32=5), taking into account the efficiency of the coding and th
