MAC地址有单播、组播、⼴播之分。单播地址(unicast address)表⽰单⼀设备、节点，多播地址或者组播地址(multicast address、group address)表⽰⼀组设备、节点，⼴播地址(broadcast address)是组播的特例，表⽰所有地址，⽤全F表⽰：FF-FF-FF-FF-FF-FF。当然，三层的IP地址也有单播、组播、⼴播之...
MAC地址分成两部分,前24位是组织唯一标识符(OUI, Organizationally unique identifier),后24位由厂商自行分配。 MAC地址有单播、组播、广播之分。单播地址(unicast address)表示单一设备、节点,多播地址或者组播地址(multicast address、group address)表示一组设备、节点,广播地址(broadcast address)是组播的特例,表示所有...
NLB 叢集電腦會透過 ARP 回應 NLB 叢集 MAC 位址 (Multicast MAC address),switch 便會將封包送至 NLB 叢集的 switch ports [註:有些 switch 無法處理 Multicast MAC address]如何區分 Unicast MAC address 與 Multicast MAC address?首先我們先看看 MAC address 的結構,共有 32bits 如下,在 IP Multicast 中...
address are 0x01005e, the 25th bit is 0, and the 23 least significant bits are the same as the 23 least significant bits of an IPv4 multicast address, as shown in the figure. For example, the multicast MAC address corresponding to the IP multicast address 224.0.1.1 is 01-00-5e-00-01...
This is my first time setting up Windows NLB. I would like to verify one thing about the multicast\unicast mac addresses. I realized a unique mac address is created for the NLB cluster. My question is as soon as the cluster is created, will this new cluster mac address be available righ...
A first node may transmit, to a second node, based on a unicast MAC address of the second node or a multicast MAC address associated with the second node, a discover message that may include a first MAC address or a first range of MAC addresses. The first node may receive an offer ...
To receive multicast, the UE however needs to be “connected” and will therefore also need to use the uplink, as with unicast. NR multicast inherits most of the functionalities from NR unicast - including those that address reliability, coverage, latency, and mobility. Efficiency and ...
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...

When you use the multicast method, each cluster host retains the original MAC address of the adapter. In addition to the original MAC address of the adapter, the adapter is assigned a multicast MAC address, which is shared by all cluster hosts. The incoming client requests are sent to all ...
