Abstract: A method and an apparatus determines a network device receiving a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface. A first physical layer clock is determined based on the first signal. A second physical layer clock is determined based on the at least one second signal or the first physical layer clock and the at least one second signal. The first physical layer clock or the second physical layer clock is used as a sending clock of a non-flexible Ethernet interface. The network device includes the first flexible Ethernet interface and the non-flexible Ethernet interface.

Abstract: A method includes: a first network device obtains a synchronization mode indication and synchronization information, where the synchronization mode indication indicates a target network device to perform synchronization based on the synchronization information. The first network device sends the synchronization mode indication and the synchronization information through a network that supports FlexE. A second network device receives the synchronization mode indication and the synchronization information through a network that supports FlexE. The second network device performs synchronization based on the synchronization mode indication and the synchronization information.

Abstract: A thermoplastic composition includes a poly(etherimide-siloxane) copolymer having a siloxane content of more than 0 to less than 50 weight percent based on the total weight of the poly(etherimide-siloxane) copolymer; an aromatic polyketone; and a mineral filler having a particle diameter of 0.1-2 micrometers. The thermoplastic composition has a lower toxicity index than the same composition without the aromatic polyketone, the mineral filler, or both, as determined in accordance with EN53505.

Abstract: Compositions based on polycarbonate copolymers to provide ultra-clean materials and articles useful in the hard disk drive and semiconductor industries. In one aspect, the compositions include a polycarbonate copolymer based on a sebacic acid, BPA, PCP polyestercarbonate. The compositions may be used with or without other polymers, fillers or additives. The compositions based on this polycarbonate copolymer exhibit ultra clean performance, low organic contamination, low LPC, and low ionic contaminations. Meanwhile, the compositions also exhibit good flow ability, good ductility and good surface quality.
