Match each IPv6 base header field to its correct functional description.
- Payload LengthIndicates the size in bytes of the packet data carrying extension headers and upper-layer data, excluding the 40-byte base header.
- Flow LabelIdentifies packets belonging to a specific communication flow to maintain consistent routing path handling without deep packet inspection.
- Next HeaderSpecifies the protocol type immediately following the base header or identifies the first extension header.
- Hop LimitDecrements by 1 at each routing hop to prevent infinite packet looping, discarding the packet when it reaches zero.
Cevap
Payload Length pairs with describing payload size excluding the 40-byte base header; Flow Label pairs with identifying specific packet flows for path handling; Next Header pairs with specifying the encapsulated protocol or extension header; Hop Limit pairs with decrementing at each hop to prevent loops.
Each item matches its corresponding function: Payload Length measures bytes beyond the fixed 40-byte base header, Flow Label tags specific packet streams for uniform routing treatment, Next Header identifies protocol payloads or extension headers, and Hop Limit prevents loops by decrementing at each hop.
