A Method and System for Non-Disruptive Reset of a Virtual Channel Utilizing a Common Channel-Administrative Path

In some instances of a virtual channel, the path carrying channel-data traffic is logically different from a path carrying channel-administrative traffic. In such cases, when

attempting to reset the virtual channel, it is necessary to synchronize clearing of channel-data traffic, and channel-administrative traffic associated with the channel-data traffic. An existing solution uses a dedicated channel-administrative traffic path for each channel-data traffic path. Thereafter, at a first end of the link, both the channel-data traffic path and the dedicated channel-administrative traffic path are reset. Synchronization in the existing solution is achieved by enabling a path reset at the first end of the link to be sensed at a second end. Consider a situation wherein, a common channel-administrative traffic path is shared by multiple virtual channels. Here, if the existing solution is used, other virtual channels could be disrupted, when a virtual

channel is reset due to resetting of the common channel-administrative path.

Disclosed is a method and system for non-disruptively resetting a virtual channel associated with a common channel-administrative path by signaling an intention to reset the virtual channel using a reset-request command.

The method and system signals an intention to reset a virtual channel by sending the reset-request command over the common channel-...
