Techniques for combining the functionality of fabric interconnects and switches (e.g., Top-of-Rack (ToR) switches) into one network entity, thereby reducing the number of devices in a fabric and complexity of communications in the fabric. By collapsing FI and ToR switch functionality into one network entity, server traffic may be directly forwarded by the ToR switch and an entire tier is now eliminated from the topology hierarchy which may improve the control, data, and management plane. Further, this disclosure describes techniques for dynamically managing the number of gateway proxies running on one or more computer clusters based on a number of managed switch domains.

Managing traffic for endpoints in data center environments to provide cloud management connectivity

Techniques for automating the provisioning, configuring, and onboarding of network devices into a cloud management platform. The cloud management platform can be used to manage network devices that are provisioned in on-premise environments, cloud environments, and/or hybrid environments. However, it can be a cumbersome and error-prone process for a user to manually configure each of the network devices with connectivity settings needed to be managed by the cloud management platform. The techniques described herein provide an automated process to distribute connectivity information to the network devices to allow them to be managed by the cloud management platform. Once connected to the cloud management platform, the techniques described herein further include automating the process for attaching the network devices with the appropriate user account registered with the cloud management platform.

Automated provisioning of endpoint devices with management connectivity

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.

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.

Methods and devices for controlling traffic in a multi-level system are described. A first counter associated with a first node in a first level of the system is incremented. A second counter associated with a second node in an upstream level of the system is incremented. The first counter is incremented more frequently than the second counter.
