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 herein describe using virtual destinations to route packets through a NoC. In one embodiment, instead of decoding an address into a target destination ID of the NoC, an ingress logic block assigns packets for multiple different targets the same virtual destination ID. For example, these targets may be in the same segment or location of the NoC. Thus, instead of the ingress logic block having to store entries in a lookup-table for each target, it can have a single entry for the virtual destination ID. The packets for the targets are then routed using the virtual destination ID to a decoder switch in the NoC. This decoder switch can then use the address in the packet (which is different than the destination ID) to select the appropriate target destination ID.

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.
