摘要： Embodiments of the apparatus for modifying packet headers relate to programmable modifications of packets by applying commands to generalized protocol headers. Each protocol header of incoming packets is represented in a generic format specific to that protocol to enable modifications to packet headers. Missing fields from a protocol header are detected, and the protocol header is expanded to a maximum size such that the protocol header contains all possible fields of that protocol, including the missing fields. Each of the fields has the same offset irrespective of which variation of the protocol the protocol header corresponds to. Modification uses a set of commands that is applied to expanded protocol headers. All of the commands are thus generic as these commands are independent of incoming headers (e.g., size and protocol).
摘要翻译：用于修改分组报头的装置的实施例涉及通过向广义协议报头应用命令来对分组的可编程修改。传入分组的每个协议报头以该协议特有的通用格式表示，以允许对分组报头进行修改。检测到来自协议报头的缺失字段，并将协议报头扩展到最大大小，使得协议报头包含该协议的所有可能的字段，包括丢失的字段。每个字段具有相同的偏移量，而不管协议报头对应于哪个协议的变化。修改使用一组应用于扩展协议头的命令。所有这些命令因此是通用的，因为这些命令独立于输入头部（例如，大小和协议）。

摘要： Embodiments of the present invention provide a packet processing method and a device. The method includes: receiving a data packet that is generated and sent by a destination device after the destination device receives a first interest packet that is forwarded by a source device via the forwarding node, where the data packet carries a content name that is the same as a content name of content requested by using the first interest packet; when forwarding the first interest packet, generating, a PIT entry corresponding to the first interest packet in the PIT; and when determining that the data packet carries a second interest packet, matching the content name carried in the data packet with a content name in the PIT entry, and forwarding the data packet to the source device according to a port in the matched PIT entry.

摘要： A packet forwarding method and a VXLAN gateway. A VXLAN packet is received. The VXLAN packet includes a communication packet that is sent from a first VM to a second VM; a second VNI of a subnet in which a next-hop device of the communication packet is located is determined according to a first VNI of the VXLAN packet and an IP address of the second VM of the VXLAN packet; the communication packet is encapsulated according to the second VNI; and then an encapsulated VXLAN packet is forwarded to the next-hop device through a tunnel corresponding to the second VNI, to avoid that the VXLAN gateway can implement forwarding of the VXLAN packet only after the VXLAN gateway modifies the communication packet in the payload of the VXLAN packet, and improve efficiency of forwarding the VXLAN packet.

摘要： Methods and apparatus for load balancing across member ports for traffic egressing out of a port channel are provided herein. An example method according to one implementation may include: assigning a quantized value based on current load to each of the network ports in the port channel; receiving a data packet addressed to egress through the port channel; identifying a traffic flow with which the received data packet is associated; determining whether the identified traffic flow is a new traffic flow; and selecting one of the network ports in the port channel as an egress port. Selection of the egress port may be weighted according to the quantized value of each of the network ports in the port channel.

摘要： One embodiment of the present invention provides a computing system. The computing system includes a processor and a memory storing instructions that are executed by the processor. The computing system stores in a first table a first mapping between a first switch identifier and a next-hop switch identifier for the first switch identifier, and stores in a second table a second mapping between the first switch identifier and a first media access control (MAC) address of a remote device. The computing system encapsulates a first packet, which has first MAC address as a destination address, in a first encapsulation header with the first switch identifier as an egress switch identifier of the first encapsulation header. This encapsulated packet is forwarded in a network of interconnected switches based on the first encapsulation header.

摘要： A network device includes a plurality of ports and at least one packet processor separate from a central processing unit (CPU). The packet processor is configured to forward a received packet based on a look-up of a destination address of the received packet in a table of learned entries that associate first addresses checked by the CPU to the ports of the network device, to add a new provisional entry that associates a source address with an ingress port of the received packet based on a look-up of the source address in both the learned entries and provisional entries that associate second addresses to be checked by the CPU to the ports of the network device, and to upgrade the new provisional entry to a learned entry with a delay time (e.g., a pre-determined time period) to allow the CPU to check the source address.

摘要： A method and system for improving robustness of context update messages in robust header compression are disclosed in the present document, wherein, the method includes: when sending the context update message, a compressor performing check processing on important fields in the context update message, generating a check code, and sending the check code and the context update message out together; and after receiving the context update message and the check code of the important fields in the context update message, a decompressor firstly performing checking on the important fields in the context update message, if the checking is passed, continuing to execute decompression processing, and if the checking is failed, discarding the context update message. With the present document, the probability of mistaking other compression packets for IR/IR-DYN messages due to bit errors of packet format fields can be reduced, and the correctness of packet format identification can be improved.

摘要： The present invention relates to a point code emulation apparatus and method for dividing a Common Channel Signaling System No. 7 (or SS7) signaling network into two or more networks. The point code emulator is adapted to receive TCAP messages from two or more subnets and converts, for the messages crossing over the subnets, the information of the TCAP messages, including originating point code, destination point code, and transaction identifier, (and optionally, calling party number and called party number), and forwards to the other one of the two or more subnets. Correspondence among the two or more subnets may be provisioned by an authorized user of the system, may be learned automatically by the system based on ISUP message correspondences or previous TCAP transactions, or may be automatically discovered by the system broadcasting messages to nodes in the destined one of the two or more subnets.
