Abstract: Example methods and computer systems for packet handling for active-active stateful service insertion are disclosed. One example may involve a computer system detecting a packet addressed from a source address to a service endpoint address. Based on configuration information associated with the service endpoint address, the computer system may identify a first active logical service router (SR) and a second active logical SR that are both associated with the service endpoint address and configured to operate in an active-active mode. The first active logical SR may be selected over the second active logical SR by mapping tuple information to the first active logical SR. The computer system may generate an encapsulated packet by encapsulating the packet with an outer header addressed to an outer destination address associated with the first active logical SR and send the encapsulated packet towards the first active logical SR for processing according to a stateful service.

Abstract: Example methods and systems for virtual tunnel virtualized computing instance (VTEP) learning based on transport protocol information are described. In one example, a computer system may learn first mapping information and second mapping information. The first mapping information may associate (a) a first VTEP with (b) first transport protocol information and inner address information associated with a first virtualized computing instance.

In response to determination that the egress packet specifies the first transport protocol information, a first encapsulated packet may be generated and sent towards the first VTEP. Otherwise, a second encapsulated packet may be generated and sent towards the second VTEP.

Abstract: Example methods and systems for service request handling with protocol translation are described. In one example, in response to intercepting a service request from a virtualized computing instance, a computer system may generate and send a translated service request towards a service node. The translated service request may be generated by performing a first translation of the service request from a service protocol to a data exchange protocol supported by both a client node running on the computer system and a service node. In response to receiving the service response that is generated according to the data exchange protocol from the service node, the computer system may generate and send a translated service response towards the virtualized computing instance. The translated service response may be generated by performing a second translation of the service response from the data exchange protocol to the service protocol.

Abstract: A data transmission method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to rolling sequence numbers of received data packets. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node transmits a replacement data packet to the receiving node. The replacement data packet carries a different rolling sequence number.
