802.11i
802.11i
IEEE 802.11i is a comprehensive
network (WLAN) that describes
to the
MAC
encryption techniques than the original
Encryption Standard (AES).
The original WPA, which can be considered a subset of 802.11i, uses Temporal Key
Integrity Protocol (TKIP) for encryption. WPA2 is backwards-compatible with products
that support the original WPA
IEEE 802.11i /
802.11j
EEE 802.11j standardizes chipsets that can use both the 4.9 and 5 GHz radio bands
according to rules specified by the Japanese government to open both bands to indoor,
outdoor and mobile wireless LAN applications. The regulations require companies to adjust
the width of those channels. IEEE 802.11j allows wireless devices to reach some previously
unavailable channels by taking advantage of new frequencies and operating modes. This is
partially an attempt to mitigate the crowding on the airwaves, and has tangential
relationships to IEEE 802.11h.
802.11k
IEEE 802.11k is a developing
auto-manage network
utilization. 802.11k capable networks will automatically load balance network traffic across
APs to improve network performance and prevent under or over-utilization of any one AP.
802.11k will eventually complement the
ensuring QoS for multimedia over a wireless link.
802.1p
802.1p is an extension of the IEEE 802 standard and is responsible for QoS provision. The
primary purpose of 802.1p is to prioritize network traffic at the data link/ MAC layer. 802.1p
offers the ability to filter multicast traffic to ensure it doesn't increase over layer 2 switched
networks. It uses tag frames for the prioritization scheme.
