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

Patent number: 7565436Abstract: A method of supporting multiple quality of service (QoS) levels for data being transmitted between two networking devices, such as customer equipment (CE), that use Ethernet and Frame Relay (FR). The method supports multiple QoS services in a network where a first CE is connected to a first edge device (interworking unit) using the Ethernet protocol and a second CE is connected to a second edge device using the FR protocol. The edge devices may be directly connected together or they may be connected through a network backbone using any generally accepted network protocol. The first CE may be connected to the first edge device using a single Ethernet port, multiple Ethernet ports, a single virtual local area network (VLAN), or multiple VLAN's. The second CE is connected to an edge device using a single data link connection (DLC), or multiple DLC's. The method ensures QoS for data transmitted between the first and the second CE via the Ethernet protocol to the FR protocol and vice versa.Type: GrantFiled: December 24, 2003Date of Patent: July 21, 2009Assignee: Nortel Networks LimitedInventors: Sameh Rabie, Richard Pommainville, John Whatman, Bashar Abdullah, John Rosser Davies, Baghdad Barka

Patent number: 7505466Abstract: A method and system for interworking between an Ethernet communication network and an ATM network, in which a first network interface is operable to communicate with the Ethernet communication network using an Ethernet communication protocol. A second network interface is operable to communicate with the ATM communication network using an ATM protocol. A processing unit is in communication with the first network interface and the second network interface, in which the processing unit encapsulates frames received from the Ethernet network into ATM frames, decapsulates frames received from the ATM network to recover Ethernet frames and maps parameters corresponding to the received one of the ATM and Ethernet frames into the other of the ATM and Ethernet frames, the mapped parameters including connection configuration control plane information and data plane parameters corresponding to individual frames.Type: GrantFiled: December 21, 2004Date of Patent: March 17, 2009Assignee: Nortel Networks LimitedInventors: Sameh Rabie, Osama Aboul Magd, Bashar Abdullah, Baghdad Barka
