Abstract
In one embodiment, a method can include: (i) pre-configuring a stream control transmission protocol (SCTP) association; (ii) receiving a transmission control protocol (TCP) packet in a network device, where the TCP packet is intended for a destination node; (iii) encapsulating the TCP packet into an SCTP payload; and (iv) transmitting the SCTP payload across a wide area network (WAN).
Claims22
A method, comprising:
- pre-configuring a plurality of stream control transmission protocol (SCTP) associations;
- receiving a transmission control protocol (TCP) packet in a network device, the TCP packet being intended for a destination node;
- encapsulating the TCP packet into an SCTP payload for a selected one of the SCTP associations based on a quality of service (QoS) determination for the TCP packet;
- sending local acknowledgements in TCP for window scaling to increase a capacity of the selected SCTP association;
- and
- transmitting the SCTP payload across a wide area network (WAN) in an SCTP stream on the selected SCTP association.
3 more elements
A method, comprising:
- receiving a stream control transmission protocol (SCTP) payload in a network device coupled to a wide area network (WAN), wherein the SCTP payload includes an encapsulation of a first transmission control protocol (TCP) packet, the first TCP packet being intended for a destination node;
- de-encapsulating the SCTP payload, the SCTP payload being received from a selected one of a plurality of SCTP associations based on a quality of services (QoS) determination for the TCP packet;
- regenerating the first TCP packet for transmission to the destination node;
- and
- sending local acknowledgements in TCP for window scaling to increase a capacity of the selected SCTP association.
2 more elements
An apparatus, comprising:
- a first interface configured to receive transmission control protocol (TCP) packets;
- a circuit configured to encapsulate the TCP packets into stream control transmission protocol (SCTP) payloads for a selected one of a plurality of pre-configured SCTP associations based on a quality of service (QoS) determination for the TCP packets;
- and
- a second interface configured to transmit the SCTP payloads across a wide area network (WAN) in an SCTP stream on the selected SCTP association, wherein local acknowledgements in TCP are used for window scaling to increase a capacity of the selected SCTP association.
1 more element
An apparatus, comprising:
- a first interface configured to receive stream control transmission protocol (SCTP) payloads having encapsulated transmission control protocol (TCP) packets;
- a circuit configured to de-encapsulate the SCTP payloads and regenerate the TCP packets, the SCTP payload being received from a selected one of a plurality of SCTP associations based on a quality of service (QoS) determination for the TCP packet;
- and
- a second interface configured to transmit the TCP packets, wherein local acknowledgements in TCP are used for window scaling to increase a capacity of the selected SCTP association.

- means for encapsulating the first TCP packet into an SCTP payload for a selected one of the SCTP associations based on a quality of service (QoS) determination for the TCP packet;
- means for sending local acknowledgements in TCP for window scaling to increase a capacity of the selected SCTP association;
- and
- means for transmitting the SCTP payload across a wide area network (WAN) in an SCTP stream on the selected SCTP association.
