    Description

    Some VNFs require internal VLDs to have MTU higher than the traditional default 1500 bytes. In addition, some VNFs might expect to communicate in a NS VLD using an MTU higher than the aforementioned value.

    This feature proposes the addition of a new MTU field in NS VLDs and VNF internal VLDs. That MTU would have to be configured by the RO at instantiation time. It is assumed that the physical interfaces of the compute nodes used both for overlay and underlay networks must have an MTU value higher than the requested MTU value. Otherwise, an error should be raised at instantiation time.

    It is left for the design phase whether it makes sense to add the MTU as an instantiation parameter to be configured for both NS VLDs and VNF internal VLDs.
