Abstract

A category of auxiliary tasks (such as routing configuration management or packet content transformation) associated with transmission of network packets between sets of network endpoints is determined. A virtual router is configured to transmit the packets between the sets of network endpoints. Connectivity is enabled between the virtual router and an auxiliary task offloading resource. Results of an auxiliary task performed at the offloading resource are used to transmit at least some packets between the sets of network endpoints.

Claims20

Dependent claims

A system, comprising:

one or more computing devices;
wherein the one or more computing devices include instructions that upon execution on or across the one or more computing devices cause the one or more computing devices to:
determine, based at least in part on input received via one or more programmatic interfaces from a client of a provider network, a category of auxiliary tasks associated with transmission of at least a subset of network packets between a first isolated network and a second isolated network, wherein the category is a member of a set comprising (a) one or more routing configuration management categories and (b) one or more packet content transformation categories;
configure a virtual router to transmit network packets between the first isolated network and the second isolated network, wherein the virtual router comprises a plurality of packet processing nodes including a fast-path node and an exception-path node, wherein the fast-path node is configured to (a) obtain executable versions of one or more routing actions from the exception-path node and (b) implement the routing actions using the executable versions;
enable, using metadata provided to the exception-path node, communication between an auxiliary task offloading resource and at least one packet processing node of the virtual router, wherein the auxiliary task offloading resource is configured to perform the category of auxiliary tasks;
and
transmit, by a packet processing node of the virtual router, using a result of a particular auxiliary task of the category, a particular network packet to the second isolated network, wherein at least a portion of contents of the network packet originated at the first isolated network, and wherein the particular auxiliary task is performed at the auxiliary task offloading resource.

4 more elements

A computer-implemented method, comprising:

determining, based at least in part on input received via one or more programmatic interfaces, at least a first category of auxiliary tasks associated with transmission of network packets between a first set of network endpoints and a second set of network endpoints, wherein the first category is a member of a set of categories comprising (a) one or more routing configuration management categories and (b) one or more packet content transformation categories;
configuring a virtual router to transmit network packets between the first set of network endpoints and the second set of network endpoints;
enabling connectivity between an auxiliary task offloading resource and the virtual router, wherein the auxiliary task offloading resource is configured to perform at least the first category of auxiliary tasks;
and
transmitting, by the virtual router, using a result of a particular auxiliary task of the first category, a particular network packet to an endpoint of the second set of network endpoints, wherein at least a portion of contents of the particular network packet originated at an endpoint of the first set of network endpoints, and wherein the particular auxiliary task is performed at the auxiliary task offloading resource.

2 more elements

One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors cause the one or more processors to:

determine, based at least in part on input received via one or more programmatic interfaces, a category of auxiliary tasks associated with transmission of network packets between a first set of network endpoints and a second set of network endpoints, wherein the category is a member of a set comprising (a) one or more routing configuration management categories and (b) one or more packet content transformation categories;
configure a virtual router to transmit network packets between the first set of network endpoints and the second set of network endpoints;
enable connectivity between an auxiliary task offloading resource and the virtual router, wherein the auxiliary task offloading resource is configured to perform at least the first category of auxiliary tasks;
and
transmit, by the virtual router, using a result of a particular auxiliary task of the category, a particular network packet to a network endpoint of the second set of network endpoints, wherein at least a portion of contents of the particular network packet originated at an endpoint of the first set of network endpoints, and wherein the particular auxiliary task is performed at the auxiliary task offloading resource.
