  • Patent number: 11770399
    Abstract: Various examples are provided related to software and hardware architectures that enable lightweight and trust-aware routing. In one example, among others, a method for trust-aware routing includes calculating trust values to represent how much a node can be trusted to route packets through its router. Each node can store the trust values of routers that are one hop and two hops away from it, which represent direct trust and delegated trust, respectively. When a router receives a packet, the router can update trust values and forward the packet to the next hop.

  • Patent number: 11757776
    Abstract: A dynamic SRMS (DSRMS) in a MPLS network generates unique segment identifiers for nodes of the network lacking segment identifiers (SIDs). The DSRMS receives network information from other nodes of the network that may include, for example, Internal Gateway Protocol (IGP) routing information, advertised prefix values for the nodes, and label values used in MPLS routing. The DSRMS analyzes the information and identifies nodes of the network that are not associated with a SID. For each identified node, the DSRMS generates a unique SID and then announces the SID to other nodes within the network. Generating the unique SID may include executing a hashing function using the IP address of the identified node as an input.

  • Patent number: 11748285
    Abstract: Ordering rules, such as those enforced by the peripheral component interconnect express (PCIe) protocol for data communications, can be intelligently enforced for independent transactions. A single device might host or be associated with multiple PCIe devices, such as virtual machines, and treating requests from these separate PCIe devices as coming from separate domains enables the ordering rules to be bypassed for certain transactions. Further, since a virtual machine might host multiple applications or be associated with multiple processors that can submit independent requests, the ordering rules can be bypassed at the transaction level in at least some instances. The ability to intelligently bypass ordering rules can help to improve the performance of the overall system, as requests do not need to be unnecessarily delayed and data storage capacity can be more fully utilized.

The protocol stack modules are operable to access target devices based on different communication protocols via a physical interface. The FPGA device further includes a universal access module operable to receive, from the application module, first data and a first identity of a first target device, the first target device acting as a destination of the first data, and transmit, based on the first identity and predetermined first routing information, the first data to a first protocol stack module accessible to the first target device via the physical interface. By introducing the universal access module, it is possible to provide unified and direct communications for the application module.

  • Patent number: 11722559
    Abstract: Some embodiments of the invention provide novel methods for performing services on data messages passing through a network connecting one or more datacenters, such as software defined datacenters (SDDCs). The method of some embodiments uses service containers executing on host computers to perform different chains (e.g., ordered sequences) of services on different data message flows. For a data message of a particular data message flow that is received or generated at a host computer, the method in some embodiments uses a service classifier executing on the host computer to identify a service chain that specifies several services to perform on the data message. For each service in the identified service chain, the service classifier identifies a service container for performing the service. The service classifier then forwards the data message to a service forwarding element to forward the data message through the service containers identified for the identified service chain.

  • Patent number: 11687470
    Abstract: An expander I/O module discovery/management system includes a secondary system chassis housing an expander I/O module coupled to a server device. The server device identifies the secondary system chassis and an expander I/O module port utilized by that server device, and then generates and transmits an expander I/O module reporting communication identifying the secondary system chassis and the expander I/O module port. A primary system chassis houses a switching I/O module coupled to the expander I/O module. The switching I/O module receives the expander I/O module reporting communication and determines that the secondary system chassis identified in the expander I/O module reporting communication is different than the primary system chassis. In response, the switching I/O module assigns a virtual slot to the expander I/O module, and assigns a virtual port associated with the virtual slot to the expander I/O module port identified in the expander I/O module reporting communication.
