Function Documentation

EthGtpip_ProcessDownlinkBulk()

uint64_t EthGtpip_ProcessDownlinkBulk	(	EthGtpip *	g,
		struct rte_mbuf *	pkts[],
		uint32_t	count
	)

Process downlink packets.

Parameters

pkts	Ethernet frames received on N6 interface.
count	quantity of pkts , maximum is 64.

Returns

bitset of accepted packets.

If a packet carries IP traffic that matches a known UE in g , its Ethernet header is removed and then the packet is encapsulated in GTP-U tunnel by prepending outer Ethernet + outer IP + outer UDP + GTPv1 headers.

EthGtpip_ProcessUplinkBulk()

uint64_t EthGtpip_ProcessUplinkBulk	(	EthGtpip *	g,
		struct rte_mbuf *	pkts[],
		uint32_t	count
	)

Process uplink packets.

Parameters

pkts	Ethernet frames received on N3 interface.
count	quantity of pkts , maximum is 64.

Returns

bitset of accepted packets.

If a packet carries GTP-U traffic that matches a known UE in g , its outer Ethernet + outer IP + outer UDP + GTPv1 headers are removed, and then a new Ethernet header is prepended.
