Systems and methods for prioritizing multicast streams in an Internet Group Management Protocol (IGMP) network are provided. According to one implementation, a process, which may be executed by a router, is configured, in response to a reboot scenario, to query a plurality of hosts regarding membership in a plurality of IGMP multicast streams according to predefined priority levels. The process is further configured to receive membership reports from the plurality of hosts. Also, the process is configured to request a server to restart the IGMP multicast streams according to the predefined priority levels.

Systems and methods for incorporating a new channel-type value in the header of a Generic Associated Channel (G-ACh) for Connectivity Fault Management (CFM) Layer-2 packets over Multi-Protocol Label Switching (MPLS) networks are provided. The channel-type value of the G-ACh header may be used for identification of the network-generated CFM Layer-2 packets. In one implementation, a system may include a processing device and a memory device, where the memory device may be configured to store instructions that, when executed, cause the processing device to obtain a Connectivity Fault Management (CFM) packet, encapsulate the CFM packet with Pseudo-Wire (PW) and Label-Switched Path (LSP) labels to create an expanded packet, and incorporate a specific channel-type value in a G-ACh header of the expanded packet to uniquely identify the CFM packet.

Service availability determination systems and methods include determining availability of a packet service in a Maintenance Interval (MI) based on frame loss measurements in short intervals &#x394;t and marking each &#x394;t as available or unavailable based on the frame loss measurements and an associated Frame Loss Ratio (FLR) threshold, wherein each &#x394;t is a High Loss interval (HLI) when exceeding the FLR threshold; utilizing a sliding window of size n, n being an integer, to determine whether the packet service is available or unavailable; and utilizing an extension period after an end of the MI with the sliding window to ensure all &#x394;t's in the MI are marked as available or unavailable.
