Abstract: Network devices, computer-readable media, and other embodiments associated with packet inspection are described. Packet inspection may be performed on data packets associated with a session, where a session can include multiple data channels and associated control channels that have been bound together. A session may be associated with an identity. Various policies may be associated with that identity. As packet inspection occurs, it can be determined whether policies are being violated on a per identity basis. If a policy is being violated, then an action may be selectively performed. The action performed may affect a single channel in the session or may affect the whole session. Different identities may have different policies. Example actions include dropping a session, throttling a session, monitoring a session, controlling the number of channels associated with a session, dropping a channel, throttling a channel, monitoring a channel, and other actions.

Abstract: An apparatus and method for implementing comprehensive QOS independent of the fabric system is disclosed. According to one embodiment, a system is provided comprising a switching medium, a plurality of line cards, a first scheduler associated with an ingress line card, and a second scheduler associated with an egress line card and communicatively coupled with the first scheduler. According to another embodiment, a line card is provided comprising a plurality of input buffers, a plurality of output buffers, output buffer status logic coupled to the output buffers operable to produce output buffer status information corresponding to each output buffer, a first scheduler coupled to the input buffers and operable to select data from the input buffers based upon the output buffer status, and a second scheduler coupled to the output buffers and operable to select data from the output buffers in accordance with Quality of Service requirements.
