Abstract: A method for establishing a virtual channel between network devices is disclosed. In the case of a local network device establishing a virtual channel with a remote network device, a virtual channel request message is sent from the local network device to the remote network device. A virtual channel acknowledgement message and a remote capability list are received and a virtual channel resume message and a local capability list are sent. The virtual channel is then enabled. In the case of a remote network device establishing a virtual channel with a local network device, a virtual channel request message is received from a local network device by a remote network device. A virtual channel acknowledgement message and a remote capability list are sent and a virtual channel resume message and a local capability list are received. The virtual channel is then enabled.

Abstract: The systems and methods disclosed herein allow for a switch (in a packet-switching network) to track buffer statistics, and trigger an event, such as a hardware interrupt or a system snapshot, in response to the buffer statistics reaching a threshold that may indicate an impending problem. Since the switch itself triggers the event to alert the network administrator, the network administrator no longer needs to sift through mountains of data to identify potential problems. Also, since the switch triggers the event prior to a problem arising, the network administrator can provide remedial action prior to a problem occurring. This type of event-triggering mechanism makes the administration of packet-switching networks more manageable.

Abstract: Disclosed are various embodiments for multiserver platforms. In some embodiments, a packet from an external network is received in a first switch. The first switch is in a first multiserver platform in which multiple servers communicate with the external network via the first switch. The first switch transmits the packet to a central switch to forward the packet to a second switch in a second multiserver platform. The central switch communicates with the external network via the first switch in the multiserver platform.
