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:...
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
Multicast on the other hand enables one-to-many communication among hosts. It enables one or more multicast sources to send one copy of a packet to multiple receivers. The packet is sent to a specific multicast address, which, unlike unicast addresses, belongs to a group of hosts rather than...

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...
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...

Some patterns in message addresses identify if they are multicast or 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 mu...
