小弟目前家裡是使用中華電信小烏龜(合勤版)當成分享器.
因網路孔已不敷使用, 想買個8port的hub來接.
目前家裡有看MOD, 也有一台NAS當成多媒體伺服器.
請問HUB有需要買有IGMP功能的嗎??(目前中華電信小烏龜是有而且有開啟)

您好,如果只是一般8port...(恕刪)
現在都是叫Switch了 已經沒有Hub這種產品
回歸正題 如果是這樣的話 那必須要換一台支援IGMP的Switch
這部分樓主可以找找

如果只是一般8port 的 hub功能, 沒有switch功能, 也會有這樣的要求嗎?
現在買不到"沒有switch功能"的hub吧
現在能買到的，不管名稱是"交換式集線器"、"交換器"，都會有switch功能
我查了一下 Wiki (英文版)
Network switch如下：
https://en.wikipedia.org/wiki/Network_switch
A network switch (also called switching hub, bridging hub, officially MAC bridge[1]) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.
Hub (network science)如下:
https://en.wikipedia.org/wiki/Hub_(network_science)
Hub is a concept in network science that refers to a node with a number of links that greatly exceeds the average. Emergence of hubs is a consequence of a scale-free property of networks.[1] While hubs cannot be observed in a random network, they are expected to emerge in scale-free networks. The uprise of hubs in scale-free networks is associated with power-law distribution. Hubs have a significant impact on the network topology. Hubs can be found in many real networks, such as Brain Network or Internet.
很多條線匯集的裝置(集線器)，稱它為hub也沒什麼錯(就不太精確)
例如可以讓很多條USB線匯集的裝置，稱為USB hub
