摘要： In accordance with various implementations, a method is performed at a multicast gateway node within an operator network, where the multicast gateway node includes one or more processors, non-transitory memory, an ingress interface, and one or more egress interfaces. The method includes determining a multicast identifier for a user device in response to obtaining a registration request associated with the user device. The method also includes generating a header for a multicast data stream based at least in part on the multicast identifier in response to obtaining a multicast flow join request. The method further includes populating a packet associated with the multicast data stream with the header. The method further includes forwarding the packet to the user device via a portion of the one or more egress interfaces, where the portion of the one or more egress interfaces is associated with the user device.

摘要： A port number extension method and a switch are provided. A first switch determines bits for identifying the first switch in a Media Access Control (MAC) address in an identifier (ID) of a specified bridge; calculates a bit for port number extension according to the bits for identifying the first switch; and combines the bit for port number extension and original bits for specifying a port, to obtain new bits for specifying a port. In this way, a problem that Spanning Tree Protocol (STP) port numbers are insufficient in a super virtual fabric with a massive quantity of ports is resolved.

摘要： An apparatus and method for performing procedures (protocols) of a PDCP (Packet Data Convergence Protocol) layer and an RLC (radio layer in an E-UMTS (Evolved Universal Mobile Telecommunications System) which has evolved from UMTS, among radio protocols of a mobile communication system. The PDCP layer performs ciphering on data (i.e., PDCP SDU) received from an upper layer, generates an indicator discriminating ciphered data and non-ciphered data (i.e., an ROHC feedback packet directly generated by the PDCP layer), and transmits the same to a lower layer (i.e., MAC layer). A PDCP SN (Sequence Number) is defined as an algorithm for ciphering the data in the PDCP layer to perform ciphering in the PDCP layer.

摘要： A method, apparatus, and machine readable storage medium is disclosed for performing network address translation (NAT) on fragments of a Internet Protocol (IP) packet, comprising: receiving a packet fragment of the packet; calculating a hash key based on a subset of header information in the fragment; if the packet fragment is the first fragment of the packet; initiating a NAT session for the packet; storing the NAT session identifier at an entry in the linked list indexed by the hash key; and if the packet fragment is not the first fragment of the packet, then: retrieving a NAT session identifier, if available, at an entry in said linked list indexed by said hash key; and performing NAT on the fragment using the NAT session identified by the NAT session identifier. The hash key is a subset of a CRC32 calculation performed on: IPv4 source address; IPv4 destination address; and IP Identifier of the fragment. If the indexed entry in the linked list is not available, accessing a second dimension of the linked list.

摘要： A method includes encapsulating, by a first virtual switch, a packet from a first virtual machine (VM) into a tunneled packet by appending the packet with a tunnel header that is addressed for a second virtual switch, wherein the packet includes a first destination address for a virtual default gateway. The first virtual switch forwards an inner packet of the encapsulated packet to a second VM. The first virtual switch acts as a virtual default gateway based on replacement of a first destination address for the virtual default gateway with a second destination address for the second VM.
