• ITU-T has published G.8275.1 (07/2014) - “Precision time protocol telecom profile for phase/time synchronization with full timing support from the network”

• Profile defines how to distribute high accuracy time for mobile base station applications of Advanced LTE (eMBMS, eICIC, CoMP) using both IEEE1588 and Synchronous Ethernet

• Interoperable PTP over Ethernet encapsulation

- Uses well-defined multicast address

- Untagged packets are used

• TWAMP RFC 5357 is a Client – Server Model with functional blocks – control Client, session-sender, server and session-reflector

• 7210 supports the server & session reflector portion of RFC5357, in base router instance for IPv4

• Limited industry support for control-client and no per service measurements

• TWAMP-Light model needs only session sender (built-into OAM-PM) and session reflector

• Simplify operations – control channel is configured

- Base router instance & per VPRN service for IPv4 support

- Session reflector port configuration is required on peer

• Distribute MPLS service traffic among multiple parallel links- load-balancing

• Mobile traffic encapsulated in GTP header- Per flow identifier: teid

• Classic fields for load-balancing won’t work

- src.ip=eNB, dst.ip=GW, udp/tcp port=fixed

• Hash on classic fields + teid- Already supported for IP ECMP under GRT/IP-VPN

• Hash to turn into a unique label, intermediate LSRs can use

- No packet re-ordering by intermediate nodes

- LSR load-balancing based on “hash” label

• Eth PW and VPLS services

IS-IS for IPv6

• The IS-IS protocol extended to support the IPv6 address family

• Native support – RFC 5308

- 2 new TLV Types

– IPv6 Reachability TLV [Type 236] [0xEC]

– IPv6 Interface Address TLV [Type 232] [0xE8]

- IPv6 Protocol Identifier

– IPv6 NLPID 142 [0x8E]

– This is carried in the existing protocols support TLV 129

• IPv4 and IPv6 topologies in a single IS-IS instance be congruent

- Single SPF run for both protocols, so all area routers must support the same set of protocols (IPv4-only, IPv6-only, IPv4/IPv6)

• Link up doesn’t equate to link quality

• Calculate CRC error-rate detected on an Ethernet port over a pre-configured window

- Raise event/trap when thresholds crossed

– Thresholds defined with two variable: M * 10E-N

- M = Multiplier

- N = Exponent

- Example: M=5, N=6 sets the threshold at 5 * 10-6

– Configurable Signal Degrade (SD) Threshold

– Configurable Signal Fail (SF) Threshold

– Configurable Window (W), in seconds.

- CRC Error Rate is calculated as a sliding window average with error rates collected every seconds
