A computer-implemented method, and a related system, for facilitating data communication of a trusted execution environment. The method includes: processing a plurality of data packets to form a data stream including the plurality of data packets. Each data packet includes respective metadata. The data stream is a single continuous data stream in application-layer such that a boundary between two adjacent packets are not easily identifiable. The method also includes transmitting the data stream to or from a network interface module for the trusted execution environment.

Disclosed is a .[.UGMII.]. system to interface multirate devices including 10 gigabit per second data exchange rates. Mode selection is enabled to provide for automatic detection and adaptation to any transmit rate including 10M, 100M, 1G, and 10G. Mode selection comprises the negotiation between the UGMII extension sublayers located at the MAC and PHY to select between one of several operational modes including: XGIVIII communication, GIYIII encapsulation, Clause 22 MDIO register management and Clause 45 MDIO register management. Selection of UGMII and XGMII operating modes are negotiated between the MAC and PHY using ordered sets to announce and acknowledgement a mode change. In one embodiment 802.3 Clause 46 defined ordered sets are utilized.

Methods and systems for transmitting data are presented. Data received from at least one data source is retained in at least one buffer. In one example, initial hierarchical data may be provided from the at least one buffer to a device, followed by additional hierarchical data. In one example, the data is received into the at least one buffer via a multicast connection, and the data is provided to the device via a point-to-point connection.

To handle network traffic, a Deep Packet Inspection (DPI) node receives, from a Policy and Charging Rules Function (PCRF) network node, packet inspection control data that maps a specific service to an identifier. The DPI node identifies that a data packet pertains to the specific service. The identifying comprises performing DPI on at least a data section of the data packet. The DPI node notifies the PCRF network node that the DPI node received the data packet and that the data packet pertains to the specific service. The DPI node marks the data packet with the identifier in accordance with the packet inspection control data received from the PCRF network node.

A user equipment receives incoming data packets from one of a plurality of bearers. The incoming data packets comprise a first identifier indicating a source. The user equipment also detect outgoing data packets which include a second identifier indicating the source of the first identifier as destination of the outgoing data packet. The user equipment routes detected outgoing data packets which include the second identifier to the same bearer from which the incoming data packets having said first identifier are received. The detecting and routing is selectively activated on the basis of a control signal.

In a mobile communication environment, the data traffic is mapped to a number of bearers. In a downlink direction, this is accomplished by filtering data packets on the basis of an identifier which is included into the data packets in response to packet inspection. In the uplink direction, a mirroring function is applied which detects incoming data packets, which are received on one of a plurality of bearers and have a first identifier, and outgoing data packets having a second identifier which is complementary to the first identifier. The outgoing data packets having the complementary second identifier are routed to the same bearer from which the incoming data packets are received.

Disclosed is a method and an apparatus for transmitting and receiving data via a MAC protocol in a mobile communication system. The method includes inputting at least one Service Data Unit (SDU) containing transmission data through a corresponding logical channel and generating at least one first Protocol Data Unit (PDU) that includes said at least one SDU without including multiplexing information for identification of the logical channel, by a first transmission entity; acquiring the first PDU and generating a second PDU including the first PDU in a payload of the second PDU, by a second transmission entity that operates between the first transmission entity and a physical layer; inserting the multiplexing information for identification of the logical channel corresponding to said at least one first PDU into header information of the second PDU; and transmitting the second PDU through the physical layer. The method can reduce load due to additional processing, such as a bit operation or memory copying, in a receiver requiring high speed data transmission.

A Chip-to-Chip (C2C) interface utilizing Flexible Ethernet (FlexE) includes circuitry configured to provide a packet interface on a single card or over backplane/fabric links between two devices, wherein the circuitry comprises flow control and channelization for the FlexE. Each of the two devices can include any of a Network Processor (NPU), a Fabric Interface Card (FIC), a framer, and a mapper. A rate of the FlexE can be increased to support additional information for the flow control and the channelization.
