A method of configuring a set of conversation identifiers (IDs) at a network device in a distributed resilient network interconnect (DRNI) of a link aggregation group is disclosed. The method starts with initializing the set of conversation IDs, wherein the initialization includes setting entries of a Boolean vector associated with the set of conversation IDs to be a sequence of zeroes, and wherein the Boolean vector includes values indicating processing the set of conversation IDs through the single gateway or the single aggregator of the network device. The method continues with determining that distribution of the set of conversation IDs needs to be updated, setting values of an operational vector indexed by the conversation IDs, and setting values of the Boolean vector, wherein the Boolean vector lists whether the single gateway or the single aggregator of the network device is associated with each of the conversation IDs.

A method supporting a distributed resilient network interconnect (DRNI) in a link aggregation group upon communication failure at a network device is disclosed. The method starts with determining that the network device no longer communicates with its neighbor network device. The network device then determines that its partner network device no longer communicates with the partner network device's neighbor network device. The network device determines that the first portal that the network device belongs to has a higher portal priority than the second portal that the partner network device belongs to, wherein each portal is assigned a portal priority, and it determines that the network device has a lower network device priority than the neighbor network device, wherein each network device is assigned a network device priority. Then the network device halts transmitting and receiving frames of the link aggregation group at the network device.

A method of supporting a distributed resilient network interconnect (DRNI) at a network device is disclosed. The method starts with initializing the network device for operating distributed resilient control protocol (DRCP) on an intra-portal port (IPP) coupled to a neighbor network device using an intra-port link (IPL). The method continues with the network device checking that DRCP is enabled at the IPP and then enters an expired state. The network device then receives a DRCPDU and determines that the received DRCPDU is associated with the first portal it is assigned to. It determines that the received DRCPDU is compatible with the network device, and records neighbor network device's state information included in the received DRCPDU as state operational variables of the neighbor network device at the network device, wherein the neighbor network device's state information includes DRCP variables for the IPP.

A method supporting distributed resilient network interconnect (DRNI) in a link aggregation group at a network device is disclosed. The method starts with encapsulating a distributed relay control protocol data unit (DRCPDU) in a frame, wherein the DRCPDU includes a protocol data unit (PDU) structure. The PDU structure includes a type field indicating that the DRCPDU is for DRCP, a version field indicating a version number of the DRCP, and a set of type/length/values (TLVs) including: a terminator TLV indicating an end of the PDU structure, a portal information TLV indicating characteristics of the first portal, a portal configuration information TLV indicating configuration information of the first portal, a DRCP state TLV indicating variables associated with an intra-portal link (IPP), a home ports information TLV and a neighbor ports information TLV. The method continues with transmitting the frame encapsulating the DRCPDU from the network device to a neighbor network device.

A method supporting network and intra-portal link (IPL) sharing in a link aggregation group at a network device is disclosed. The method starts with transmitting frames on the IPL at the network device, where the physical link or aggregation link of the link aggregation group is dedicated to the IPL. The network device determines that the network device is configured with a network and IPL sharing method that is consistent with the neighbor network device, the network and IPL sharing method including sharing by at least one of time, tag, and encapsulation, where the network and IPL sharing method indicates sharing of the physical link or link aggregation between frames for the IPL and frames for another IPL or a network link of the link aggregation group. Then the network device transmits the frames between the network device and the neighbor network device using the network and IPL sharing method.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may receive, at a modem of the device, a plurality of data packets associated with one or more connections. The device may group, at the modem of the device, data packets, of the plurality of data packets, associated with a connection, of the one or more connections, into a container based at least in part on one or more characteristics associated with the modem or the data packets. The device may transmit, from the modem to a processor of the device, the container of grouped data packets. Numerous other aspects are provided.

A method and apparatus for in-line processing a data packet while routing the packet through a router in a system transmitting data packets between a source and a destination over a network including the router. The method includes receiving the data packet and pre-processing layer header data for the data packet as the data packet is received and prior to transferring any portion of the data packet to packet memory. The data packet is thereafter stored in the packet memory. A routing through the router is determined including a next hop index describing the next connection in the network. The data packet is retrieved from the packet memory and a new layer header for the data packet is constructed from the next hop index while the data packet is being retrieved from memory. The new layer header is coupled to the data packet prior to transfer from the router.
