Patent number: 12132780Abstract: 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.Type: GrantFiled: July 7, 2023Date of Patent: October 29, 2024Assignee: VMware LLCInventors: Jeremy Tidemann, Constantine Polychronopoulos, Marc-Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Raja Kommula, Georgios Oikonomou, Mingjie Zhao

Patent number: 11902080Abstract: A system can reduce congestion in slice-based networks, such as a virtual service network (“VSN”). The system can include a monitoring module that communicates with agents on switches, such as routers or servers. The switches report telematics data to the monitoring module, which determines slice-specific performance attributes such as slice latency and slice throughput. These slice-specific performance attributes are compared against software license agreement (“SLA”) requirements. When the SLA is not met, the monitoring module can implement a new slice path for the slice to reduce the congestion.Type: GrantFiled: May 17, 2021Date of Patent: February 13, 2024Assignee: VMware, Inc.Inventors: Raja Kommula, Jeremy Tidemann, Constantine Polychronopoulos, Marc Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Georgios Oikonomou

Publication number: 20230123237Abstract: Some embodiments of the invention provide a novel method of performing network slice-based operations on a data message at a hardware forwarding element (HFE) in a network. For a received data message flow, the method has the HFE identify a network slice associated with the received data message flow. This network slice in some embodiments is associated with a set of operations to be performed on the data message by several network elements, including one or more machines executing on one or more computers in the network. Once the network slice is identified, the method has the HFE process the data message flow based on a rule that applies to data messages associated with the identified slice.Type: ApplicationFiled: October 29, 2022Publication date: April 20, 2023Inventors: Raja Kommula, Constantine Polychronopoulos, Thayumanavan Sridhar, Marc-Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Georgios Oikonomou, Jeremy Tidemann

Patent number: 11595315Abstract: A switch in a slice-based network can be used to enforce quality of service (“QoS”). Agents can run in the switches, such as in the core of each switch. The switches can sort ingress packets into slice-specific ingress queues in a slice-based pool. The slices can have different QoS prioritizations. A switch-wide policing algorithm can move the slice-specific packets to egress interfaces. Then, one or more user-defined egress policing algorithms can prioritize which packets are sent out into the network first based on slice classifications.Type: GrantFiled: January 8, 2021Date of Patent: February 28, 2023Assignee: VMware, Inc.Inventors: Raja Kommula, Jeremy Tidemann, Constantine Polychronopoulos, Marc Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Georgios Oikonomou

Patent number: 11588733Abstract: In a slice-based network, switches can be programmed to perform routing functions based on a slice identifier. The switch can receive a packet and determine a slice identifier for the packet based on packet header information. The switch can use the slice identifier to determine a next hop. Using the slice identifier with a multi-path table, the switch can select an egress interface for sending the packet to the next hop. The multi-path table can ensure that traffic for a slice stays on the same interface link to the next hop, even when a link aggregation group (“LAG”) is used for creation of a virtual channel across multiple interfaces or ports.Type: GrantFiled: May 14, 2019Date of Patent: February 21, 2023Assignee: VMWARE, Inc.Inventors: Raja Kommula, Jeremy Tidemann, Constantine Polychronopoulos, Marc Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Georgios Oikonomou

Patent number: 11522791Abstract: Some embodiments provide a novel method for adjusting a path for a packet flow from a source machine to a destination machine in a network. The method of some embodiments identifies a condition at a first forwarding element along a first path traversed by the packet flow through the network. The first path traverses through a hardware, second forwarding element before the first forwarding element. In some embodiments, the second forwarding element includes a programmable data plane circuit. The method, in some embodiments, uses an application programming interface (API) of the programmable data plane circuit to provide a set of parameters to the data plane circuit that cause the data plane circuit to forego selecting the first path to forward the packets of the packet flow to the destination machine and instead to select a second path, not traversing the first forwarding element, to the destination machine.Type: GrantFiled: June 19, 2021Date of Patent: December 6, 2022Assignee: VMWARE, INC.Inventors: Raja Kommula, Constantine Polychronopoulos, Thayumanavan Sridhar, Marc-Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Georgios Oikonomou, Jeremy Tidemann

Publication number: 20220303195Abstract: Examples can include an optimizer that dynamically determines where to place virtual network functions for a slice in a distributed Telco cloud network. The optimizer can determine a slice path that complies with a service level agreement and balances network load. The virtual network functions of the slice can be provisioned at clouds identified by the optimal slice path. In one example, performance metrics are normalized, and tenant-selected weights can be applied. This can allow the optimizer to prioritize particular SLA attributes in choosing an optimal slice path.Type: ApplicationFiled: June 2, 2022Publication date: September 22, 2022Inventors: Jeremy Tidemann, Constantine Polychronopoulos, Marc Andre Bordeleau, Edward Choh, Ojas Gupta, Robert Kidd, Raja Kommula, Georgios Oikonomou

Patent number: 11374830Abstract: In a slice-based network, slice multiplexers can be used to anchor inter-cloud tunnels across different clouds in a slice path. The slice multiplexers can dynamically change a total allocated bandwidth of an outer tunnel and reconfigure relative slice bandwidths of inner tunnels. This can result in an optimized bandwidth allocation that enforces slice priorities, maintains required SLA performance levels, and minimizes total allocated bandwidth on the network connection. The dynamic changes can be based on slice priority levels, total number of slices, and historical slice throughput.Type: GrantFiled: December 20, 2019Date of Patent: June 28, 2022Assignee: VMWARE, INC.Inventors: Robert Kidd, Raja Kommula, Jeremy Tidemann, Constantine Polychronopoulos, Marc Andre Bordeleau, Edward Choh, Ojas Gupta, Georgios Oikonomou, Mingjie Zhao
