Patent number: 9130861Abstract: Traffic engineering and bandwidth management of bundled links may, at times, require the selection of one of a plurality of component links in a bundled link to use in admitting a connection requiring admission. While performing the selection it may be determined that more than one of the component links has the resources required to admit the connection. An admission policy may then be selected from among a plurality of admission policies. Based on the selected admission policy, a particular component link may then be selected. Such bandwidth management, based on admission policies, may be seen to be well suited to balancing and component link recovery in traffic engineered, connection-oriented MPLS networks.Type: GrantFiled: May 7, 2013Date of Patent: September 8, 2015Assignee: RPX CLEARINGHOUSE LLCInventors: Sameh Rabie, Tong Shan

Patent number: 9118590Abstract: The two types of virtual local area networks (VLANs) may be defined: p-bits-Inferred-scheduling class VLAN (p-VLAN); and VLAN-10-Only-Inferred-scheduling class VLANs (v-VLAN). As such, upon receipt of an Ethernet frame, the type of VLAN associated with the Ethernet frame may be determined. The type of VLAN provides the receiving node with an indication of a method of determining a scheduling class. A p-VLAN supports multiple scheduling classes. For a p-VLAN, the scheduling class and drop precedence for the received Ethernet frame may be determined based on a “service map” that describes the relationship between the p-bits and forwarding treatment. A v-VLAN supports a single scheduling class. As such, the scheduling class for a received Ethernet frame may be determined based on the VLAN-10 of the received Ethernet frame. The described VLAN QoS information may be configured or signaled across the network.Type: GrantFiled: March 21, 2013Date of Patent: August 25, 2015Assignee: RPX CLEARINGHOUSE LLCInventors: Sameh Rabie, Osama Aboul-Magd, Dinesh Mohan

Patent number: 9054994Abstract: A method and system for maintaining quality of service parameters for transmissions as a native Ethernet service between a first network having a first communication protocol and a second network having a second communication protocol. The interworking device includes a first network interface operable to communicate with the first communication network using the first communication protocol, a second network interface operable to communicate with the second communication network using second communication protocol and a processing unit in communication with the first network interface and the second network interface. The processing unit receives a frame from the first network in the first communication protocol, maps parameters corresponding to quality of service parameters in the first communication protocol to quality of service parameters in the second communication protocol and assembles a data packet in the second communication protocol.Type: GrantFiled: February 3, 2014Date of Patent: June 9, 2015Assignee: RPX Clearinghouse LLCInventors: Sameh Rabie, Osama Aboul Magd

Patent number: 8954109Abstract: The present invention provides a control function in an access point, switch, or like node on a wireless local area network. The control function operates to ensure frames transmitted by a user terminal are transmitted using an appropriate transmission priority scheme. The control function will assist and provide an appropriate priority level to the user terminal. Frames transmitted from the user terminal are passed through the control function, which will analyze priority level information provided in the frames to determine if the frames were transmitted using the appropriate transmission priority scheme. An enforcement action may be taken in response to identifying frames that were not transmitted using the appropriate transmission priority scheme.Type: GrantFiled: October 5, 2012Date of Patent: February 10, 2015Assignee: Apple Inc.Inventors: Osama Aboul-Magd, Hesham Elbakoury, Sameh Rabie

Publication number: 20140293791Abstract: A network includes an edge node configured to define the per-hop behaviors using a set of bits in an Ethernet header of a frame and a core node configured to receive the frame and to forward the frame according to the per-hop-behaviors. The network can also include a defined set of differentiated service classes, each differentiated service class associated with the set of per-hop behaviors, indicated in the set of priority bits. The network classifies the Ethernet frame based on at least one of a set of priority bits or information in at least one protocol layer in the frame header of the Ethernet frame and determines a per-hop behavior based on the classification.Type: ApplicationFiled: June 12, 2014Publication date: October 2, 2014Inventors: Sameh RABIE, Osama ABOUL-MAGD, Bashar ABDULLAH, Baghdad BARKA
