Abstract: A method of transmitting a deterministic flow, applied to an ingress node of the deterministic flow in a deterministic network domain, comprises, receiving a deterministic flow data packet; determining an index number of an elastic buffer queue (EQ) for buffering the deterministic flow data packet and buffering the deterministic flow data packet in the EQ corresponding to the index number of the EQ; in a current scheduling cycle Cycle x, obtaining a planned EQ resource of a next scheduling cycle Cycle (x+1), wherein the EQ resource at least comprises: an EQ index number and a planned transmission resource amount of the EQ corresponding to the EQ index number; obtaining at least one deterministic flow data packet from the EQ corresponding to the obtained EQ index number, storing the obtained at least one deterministic flow data packet into a physical queue corresponding to the next scheduling cycle Cycle (x+1).

Abstract: The invention discloses a method for dynamic allocation of slot bandwidth on a switch. First, the method sets that number of slots for dynamic allocation bandwidth is N and bandwidth needed to be dynamically allocated is B. Secondly; the method defines a minimum allocated bandwidth unit being ?B, according to requirement. Then, the method sets B/?B pieces of N-selected-one devices on main switch board. Further, the method allocates the bandwidth B to all N-selected-one devices on the main switch board, and makes input bandwidth of every N-selected-one device being N*?B. Finally, the method outputs strobe signal from a control logic chip to control said N-selected-one device, and bandwidth is allocated to the slot. The method, proposed by the invention, makes that bandwidth from service processing board slot to the main switch board can be dynamically allocated, and bandwidth allocated to each slot is flexible.

Abstract: The invention discloses a method for dynamic allocation of slot bandwidth on an exchange. First, the method sets that number of slots for dynamic allocation bandwidth is N and bandwidth needed to be dynamically allocated is B. Secondly; the method defines a minimum allocated bandwidth unit being &Dgr;B, according to requirement. Then, the method sets B/&Dgr;B pieces of N-selected-one devices on main exchange board. Further, the method allocates the bandwidth B to all N-selected-one devices on the main exchange board, and makes input bandwidth of every N-selected-one device being N*&Dgr;B. Finally, the method outputs strobe signal from a control logic chip to control said N-selected-one device, and bandwidth is allocated to the slot. The method, proposed by the invention, makes that bandwidth from service processing board slot to the main exchange board can be dynamically allocated, and bandwidth allocated to each slot is flexible.
