首先我們先看看 MAC address 的結構,共有 32bits 如下,在 IP Multicast 中的前 23 個 Bits 是固定的,源由請看【為何IP Multicast 位址的 MAC address 必須擠到 23 位元裡面?】有詳細的說明,但是在 NLB 使用的 Multicast 模式中沒有這個限制,因為 NLB 的 Multicast 只有使用到 Layer 2 的 Multicast 協定:...
Range of IP Multicast Addresses IP multicast addresses used by network-layer multicast are required to enable multicast sources and group members to communicate. IPv4 multicast addresses The Internet Assigned Numbers Authority (IANA) allocates Class D address space to IPv4 multicast. An IPv4 address ...
Multicast Requires multicast-enabled network infrastructure. Deploying multicast in a network involves configuring routers and switches to support IGMP. 8 Unicast Simple network configuration. Setting up a unicast connection involves straightforward IP addressing and routing. 9 Multicast Limited by network sup...
Unicast (单播) 一对一 Multicast(多播) 一对多 (可以选择特定对象) enables multiple applications to "subscribe" to a given IP address and port number and listen for messages. Broadcast(广播) 一对所有
PROBLEM TO BE SOLVED: To simultaneously execute the queuing of plural frames and to continuously transmit cells by individually managing intra-net headers and data in the case of converting a multicast frame into a unicast frame by copying an IP frame in a device and transmitting the unicast ...
In the radio access network (RAN), each MBS session is carried to UEs over one or more Multicast Radio Bearers (MRBs), which are set up to provide the needed IP multicast communication within the QoS requirements, as provided by the 5GC (see Fig. 1). These MRBs are the MBS ...
Are the DHCP Offer and DHCP acknowledgement messages unicast or multicast? No doubt the DHCP discover and DHCP request are both broadcasts, but what of the other 2? I captured a wireshark trace I did on my pc, and I can see the IP and MAC address on the packets are indicative of uni...

not.For example, in IPv4, the most significant four bits determine if an address is a multicast one or not. In this case, multicast addresses must present the bit sequence of 1110. IPv6 is another protocol that supports multicast. In this protocol, multicast addresses use the prefix ff00:...
[要点解析] IPv6支持3种基本地址类型:单播(unicast)地址、组播(multicast)地址、任意播(anycast)地址。这3种地址类型的定义及其相互间区别见表6-4。地址类型 定义 备注 单播地址 是点对点通信时使用的地址,目的地址为某一台计算机或路由器的IP地址 此地址仅标识一个接口。网络负责把对单擂地址发送的分组送到该接口...
