Patent number: 7957293Abstract: The invention provides a system and method for identifying and communicating congested paths throughout a network fabric. Briefly, the present invention augments the congestion management mechanism defined in ASI to allow for the communication of congested paths through the fabric, rather than the simple congested output port notification supported today through the use of DLLPs. Further, it also uses the communication mechanisms already defined in the ASI specification to implement this additional capability. Specifically, the present invention uses Transaction Layer Packets (TLPs) to communicate the information concerning congested flows throughout the network. This packet type allows the inclusion of much more information than DLLPs, allowing a more comprehensive and elegant solution to the issue of congestion management in an Advanced Switching network fabric.Type: GrantFiled: January 22, 2010Date of Patent: June 7, 2011Assignee: Jinsalas Solutions, LLCInventor: David Mayhew

Patent number: 7948974Abstract: Creating a low-bandwidth channel in a high-bandwidth channel. By taking advantage of extra bandwidth in a high-bandwidth channel, a low-bandwidth channel is created by inserting extra packets. When an inter-packet gap of the proper duration is detected, the extra packet is inserted and any incoming packets on the high-bandwidth channel are stored in an elastic buffer. Observing inter-packet gaps, minimal latency is introduced in the high-bandwidth channel when there is no extra packet in the process of being sent, and the effects of sending a packet on the low-bandwidth channel are absorbed and distributed among other passing traffic.Type: GrantFiled: December 20, 2007Date of Patent: May 24, 2011Assignee: JDS Uniphase CorporationInventors: Slawomir K.
