The SSID, BSSID and MAC address are all essential unique identifiers for a wireless network.
The Service Set Identifier (SSID) is the human readable name associated with an 802.11 wireless network.
It is often called the wireless “network name” and can be shared by multiple access points.
The Basic Service Set Identifier (BSSID) uniquely identifies a specific access point and is in the same format as a MAC address;
thus, most commonly, it is the MAC address of the access point.
The Extended Service Set Identifier (ESSID) can essentially be thought of as a group of BSSIDs that share the same Layer 2 network and the same SSID.

困惑
上网查询之后，各种说法，有的说整个路由器就一个mac，有的说路由上面的每个端口代表一个mac，还有的说有两个，一个用于wan一个用于lan。
工作的时候也听说过，无线网络中的bssid用来表示一个无线访问点的地址，和物理mac地址形式一样(48位)，并且一般只和物理mac地址相差很少(甚至两者是连续的)，并且使用wireshark和airpcap配合抓包之后，显示的bssid确实和物理mac地址相差一位，所以便以为bssid是一个虚拟的mac地址；也遇到过路由器（motorola docsis3.0）上面标注了有两个mac地址的但是两个mac地址相差很多（至今对此存有疑惑）
