5 Maintenance Maintenance agreement with line operator, in case of major failure 24hrs to restore connectivity. Failures may result from: a) improper installation b) material defects c) Force Majeure d) others (aging...?) They are repaired by the specialized company and are paid respectively by: a) installing company b) cable manufacturer c) PSNC d) PSNC...? Monitoring infrastructure is being developed...

6 Link optimization a side effect of an urgent demand for DCM module ;-) replacement of G.652 fiber with G.655 fiber (NZDS) cost reduction via: lower # of regenerators, lower # of DCF modules But: higher fiber cost and optimisation is valid for selected cases only and is wavelength/waveset/link dependent.

8 Network problems Some problems appeared during installation: few faulty modules (1 DCM, 1 AMP, 2WCMs) instantly replaced on-spot on a stretched link the devices report transmission errors, which are corrected by FEC mechanism (working on 82km with 80km interface ;-) ). This is assymetric (one way) only. Problem can be fixed by additional regenerator. No significant network problems noticed during the network operation.

9 New network services ATM transport in 10GE network continuation of former ATM network (still many customers connected with ATM) concatenation of Juniper CCC with 10GE 802.1p VLANs service in the deployment/testing phase approx. 20 connections between 5 MANs

10 Bandwidth on demand New network services establishes channels with given QoS between edge nodes of backbone network bases on VLAN and 802.1p technology tagged VLANs in QoS profiles (profiles globally defined). own topology database (defined by operator) and presented in GUI (there is no topology discovery yet) automatic (BFS) or manual VLAN path setup all decision based on configuration information gathered from switches (via SNMP and telnet) Contacts: Maciej Stróżyk

11 New software Mulitcast monitoring Trouble Ticket system Network Inventory MCast6

12 Multicast monitoring (MUVI) Multicast network topology discovery Network connections and routers availability monitoring Event messages Statistics MIB browser Multicast groups traffic visualisation Contacts: Radosław Krzywania

13 Trouble Ticket system web interface problem groups two types of tickets: trouble ticket information ticket the ticket life cycle: OPEN [UPDATED] - CLOSED (CANCELED) Trouble Ticket System was built on the basis of the Joshua Portal Framework (designed and realized in Java technology in PSNC). Contacts: Bartosz Belter bart@man.poznan.pl

14 MCast6 Multimedia streaming aaplication with IPv4-IPv6 and unicast/multicast gateway - client/server - distributed architecture with remote components - support for a number of streaming servers - client: multimedia streaming player - server: web-based application composed of: access, AA, gateway, server management plug-ins, etc. - own JMF-based streaming server - wrapper for IceCast streaming server - on-demand feature

15 MCast6 future work implementation of RTSP protocol distributed content management dynamic timetable of streaming sessions (SAP/SDP) new wrappers, e.g. for Videolan streaming sessions capture module Contacts: Roman Łapacz
