Addressing in ip networks

In this chapter we discuss our first client/server application program, Dynamic Host Configuration Protocol (DHCP). This application is discussed first because it is the first client/server application program that is used after a host is booted. In other words, it serves as a bootstrap when a host is booted and supposed to be connected to the Internet, but the host does not know its IP address.

Ôn lại cách chuyển số Dec  Bin MAC: mỗi thiết bị giao tiếp mạng được nhà SX gán cho 1 địa chỉ vật lý gọi là “MAC address”. Địa chỉ này là duy nhất cho mỗi sản phẩm. Cấu trúc IP address Địa chỉ IP là dãy gồm 32 số Bin, chia làm 4 octet (mỗi octet có 8 bit = 1 Byte) Giá trị mỗi octet: từ 0000 0000 đến 1111 1111 (từ 0 đến 255) Dãy 32 bit của địa chỉ IP được chia làm 2 phần: Network ID và Host ID Network ID + Host ID...

Multiprotocol Label Switching Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols....

This paper describes an architecture for differentiation of Quality of Service in heterogeneous wireless-wired networks. This architecture applies an “all-IP” paradigm, with embedded mobility of users. The architecture allows for multiple types of access networks, and enables user roaming between different operator domains.
