Embodiments herein describe using a virtual destination to route packets through a NoC (105). In one embodiment, instead of decoding an address as a target destination ID for the NoC (105), an ingress logic block (115) assigns the same virtual destination ID to packets for multiple different targets. For example, the targets may be located in the same segment or location of the NoC (105). Thus, the ingress logic block (115) does not have to store an entry for each target in a lookup table, but it may have a single entry for the virtual destination ID. The virtual destination ID is then used to route the packets for the targets to a decoder switch (140) in the NoC (105). The decoder switch (140) may then select an appropriate target destination ID using the address in the packet, which is different from the destination ID.

Techniques for utilizing a network gateway provisioned in a software-defined network to verify service readiness of one or more security service(s) of a service chain prior to redirecting network traffic along a given data-path to the security service(s). The gateway may be configured to open a specific port on a network device hosting a security service to transmit network policies and / or test network traffic to the security service. The network gateway may host a virtual source and / or a virtual destination and cause the virtual source to send test network traffic through the security service via the port and to the virtual destination. The gateway may then utilize the received test network traffic to determine whether a given security service satisfies a threshold health and / or functionality measurement. Once it is determined that the security service satisfies the thresholds, the gateway may cause network traffic to be redirected to the security service.

Embodiments of the present application provide a message forwarding method and device, a line card chip and a computer readable storage medium, and relate to the technical field of communication. In the case that a first network entry message is received through any network interface, a virtual destination line, an overlay ARP pointer and a physical exit of the first network entry message are obtained according to a routing parameter of the first network entry message. In the case that the physical exit represents that an exit of the first network entry message is a remote chip, an inner layer parameter of the first network entry message is updated according to the virtual destination line and the overlay ARP pointer, a Fabric message header is added to the first network entry message according to the virtual destination line, and a second network entry message is obtained. The second network entry message is forwarded through a Fabric interface, so that the number of parameters carried in the Fabric message header can be reduced, the Fabric bandwidth occupied by the message is reduced, and the difficulty of global maintenance and management is reduced.
